I'm a 43 year man and came up under a trio of old German Machinist if you had a German accent your explanations would be the same as my mentors. I'm mentoring a young man now and have been setting him down at the computer with your videos to help him learn the trade. Thanks Joe please keep up the good work
I use to be a test writer for PLTW. Your geometry example is almost identical to one of the test questions I wrote years ago. I enjoy your videos and your hands on treatment of mathematics. Thank you.
Hey Joe! Another great video! Retired with 48 years of machining 2 years ago. The whole time I wished I had paid more attention in high school. I made decent grades but didn't retain much. Like someone else said in the replies," you explain things where it's easy to wrap your head around it". Great job! Congrats on your children too! J. Lezak Chappell Hill, TX
Congratulations to Joe and Captain Victoria Pieczynski! I know you two just made your Dad the proudest Dad in Austin, or Texas or UA-cam! Huge accomplishments and obviously the result of a lot of hard work. We wish you both all the best.
Crikey Joe, I am 58 with a degree and I have learned more in the last 13.283333333333333333 minutes than in any comparable time in my life. Thank you very much. I am looking forward to the next instalment.
Joe, Fantastic video! I found you as a hobby machinist; but as a Land Surveyor, I use the information you're providing on a regular basis. You have a lot to be proud of; it's obvious that the apples haven't fallen far from the tree. Thanks again!
Great memories Joe. Thanks! When I started to run CNC mills we did the programming with a drawing , a pad of paper, a calculator, a trig table book and chart of the "G" and "M" codes typing the instructions out on a Flexwriter on paper tape. Did the program in incremental and programmed tool line rather than part line per the instructions of the co-worker who was training us. Later we figured how to use cutter compensation for part line and absolute on our own. We sure did a lot of Trig in those days. Today in my home hobby shop I draw the part in CAD pass the drawing through a program that figures the "G" code and run the machine. As the young folks say "Sweet"
First of all, better late than never, congratulations to your son and daughter on their achievements. I just want to say how grateful I am for your time and effort posting these incredible videos. I had a bit of a shaky start in life as I went to school in the 60' and 70's here in the UK and, later, at university as a mature student found I was an undiagnosed dyslexic. This had reeked havoc with my schooling. Anyway, I don't want anyone feeling sorry for me but I've worked really hard to catch up and come back from it. Also, given the time and the area I went to school in girls like me were only expected to marry and have kids. All the boys in my family are engineers or do technical jobs (my brother of whom I'm very proud, but don't tell him, is a chartered engineer). I was always interested in engineering and mechanical things and finding out how they work. I set up my little shop doing one off jobs for people with vintage British motorcycles and have taught myself with the help of books and videos like yours to do more and more jobs. Anyways, I just wanted to say a huge thank you and to say, if there's an operation or a job I'm struggling with or need help I've always come to your channel first and you've never let me down 🙂
@@joepie221 To add a little context, I'm currently on a job for a lovely guy who's terminally ill and a couple of us are trying to finish his dream bike before time catches up with him.
One proud dad with those kid's doing so well - terrific Joe, congrats to them. Thanks for the extra very useful geometry lesson - lost count of how many times I forget some of this stuff. Of course when you go thru with your inimitable logic and clear demos - it again seems so easy! Thanks Joe. My beat up old rotary table could never reach accuracy once we get into mins and secs!
Joe, thanks for the shout out to all of those suffering from our recent fires in CA. Great info on the math. When I teach I stress the math in machining. My best advice to a young machinist apprentice is to buy the machinery handbook, learn how to use it. Because you don’t need to remember the formulas but knowing how to apply them with the info you have on the print is the next best thing.
You explained changing x.x° into x° x' x" better than my nautical teacher did in 1979. Same calculation usable in 2 completely different work enviroments, nautical navigation and machine shop. I still have my Norries tables, never thought i could use them again after retiring from sea. This brought back memories, Thanks
Thanks Joe for all of your videos and presentations and congratulations to you and your family. As for some of the negative comments I learned several years ago when I started a business of my own I wanted to try and please every customer that came through the door. It only took me a few days to realize that's impossible. 99.9% of us appreciate what your doing.
I've always loved rotary table work Joe. And I applaud you for teaching this information on your channel Joe! Learning geometric theorems and axioms when I was a kid serving my apprenticeship was eye opening for me. Sadly this is lost to alot of young machinists in todays autocad and cnc world.
For the record sierra nevada brewing is in, well the Sierra Nevads. Chico California, near where the camp fire was. This has no bearing on the video, great as always.
Excellent, it's all in the triangles as you say. Thanks for the refresher. By the way, I had to go back to your setting up of the fly cutter to an exact radius and it worked a treat as usual. Thanks Joe
As always, your information is next level. Thank you so much for taking the time. If only my geometry teachers had thought to take the class to a machine shop, I would have learned so much more easily!
Nice job Joe. I’m sure this lesson is helpful to people new to machining, and a great refresher to the CAD folks that never twirled a compass. I will look for that beer at my local adult beverage store. Thanks.
Congrats on your kids! My radio shack scientific calculator from the ‘80s had a button to convert between decimal degrees and ° ‘ “ . Wish my iPhone calculator had that button. It would save a little time. Chris
Wow. That's an amazing use of Pythagorean geometry. I think it was the Transverse Parallel Theorem (TPT). Every triangle possesses 180 degrees total, interiorly. Great job, Pie. Congrats on your kids' accomplishments. Always learning from you!
Congratulations to both of your children! Thanks for the great insight into radius tangents. That information can come in handy programming an arc on a CNC as well.
@@joepie221, I ran into that a time or two, in the past. Luckily, I was programming Hurco conversational. Put in what I knew, angle of previous segment, radius of arc, angle and endpoint of the segment after the arc. Once I got that info entered, the control figured out the rest.
Hey Joe. I've been a flight test engineer for 40 years and I spend a lot of time doing mission planning and converting latitudes and longitudes back and forth between decimal degrees and DMS. I've found that pilots prefer DMS and engineers prefer decimal degrees (or even worse, radians) but sooner or later the two groups have to exchange information so I spend a lot of time doing what you just did. Wouldn't life be simpler if everybody just used the same units! Good job on the explanations.
Funny story. A novice pilot got blown off course and couldn't find the airport. She called the tower for help telling them she was lost. The ATC asked her, her current position. The pilot replied, 46 degrees, 54 feet 27 inches based on the GPS readout on her instrument. The ATC replied " You sure are !
Love your daughter for her accomplishment! Two of my daughters joined the national guard and served in Iraq, Egypt and Kuwait. I know your pride! Love your videos.
Joe thanks again for a great vid. I will hitting this part of geometry in my college machine shope mathmatics course I teach. I will play this for them in class. Even though I require a calculator as a mandatory tool the Casio 260-x they all have to learn and demonstrate they can do the math without the magic converstion button on the calculator. Looking forward to the next section.
Very good explanation Joe, I particularly liked the use of the Pie Chart at 5:40 or so. How appropriate for you to use that for your explanation of a percentage of a degree! lol. Keep the tutorials coming as I always pick up a new idea from you sharing knowledge. Cheers from John, Australia.
In this case, I believe that a Pie chart may as well be called a Joe chart, as Joe is Pie, and little wonder he is so good at geometry, when he is the key number in calculating most of things in geometry... 3.14, a Pi...e...
thank you sir, i have always struggled with that sort of thing and you just made it easier for me to understand for the 1st time! now if i can just remember it
Thanks for the shout out, man! I really appreciate it, and I appreciate everything you do on this channel. I seem to learn something new just about every time I watch. Keep up the great work!
Hey Jason. Thanks for stopping by. Jackie and Travis put me up to this. if you ever have any specific machining issues get in your way, feel free to post a question. I usually reply. best of luck with your shop.
Joe,you are my best mentor on UTube!!!! I am probably one of your older subscribers 70yrs. I will share with you my main background is medical ,ie a clinical psychologist so for me I OVER THINK EVERYTHING.Joe to that end Appreciate your dumbing itdown for this ole fart to get it!!Joe this is my first attempt to ask a question on your channel so here’s gos.My question is re your fly cutter info.I work mostly grade5 titanium.I have always sought out the best option for a fly cutter especially considering my mill is low power 2hp. So positive inserts have been my first choice.I recently saw a clip on a unique design made by Suberban Tool.This design is very beefy,but the tool holder is about flat to the bottom of its holder or parallel to its bottom unlike any other fly cutter I have seen which the tool holder projects at an angle,much your example. I can see several advantages with this design,and the video clip from Suberban. Looks truly inspiring !OK so in your vast experience is this a more hype than anything.The price of this tooling is quite expensive, around $350 plus the necessary adapter for your particular mill,in my case R-8.Again great job with your teaching,so before I invest in half my SS check I would love your feedback.I think you will agree,the design is quite unique,at least according to “FRED”.Thanks again Fred
If we are talking about the same set, the insert holder arms give the clearance needed. Mine and many others are more of the conventional design for HSS tool bits. If you don't mind grinding your own tools, and don't require insert repeatability, I personally would just make one and save the money.
Hey Joe,thanks so much for taking the time to reply,I am really flattered.Joe,that said I am sorry I could not offer a model number to accurately identify the Suberban fly cutter I was referring to.I would understand that no one could really comment on an unknown object.Thanks again,I do believe you are one of the few that. Could quite your day job and go into teaching LOL.I must say again I have learned many things I have taken for granted or just was not aware.Have a great day and continue to enhance all your followers lives in such a positive way.Fred
Thanks for the review. Math minor in college, 100 years ago +-. Trig is the most useful everyday math. All those calculus courses I took haven't been of much use. I suspect the thumbs downs are from people that can't add &/or subtract. 9,152 views in 3 days says a lot.
The comparison of 60 minutes in a degree to 60 minutes in an hour and 60 seconds in a minute is a slick one.. As a civil engineer sometimes it is useful to use angles in decimals of degrees and convert to degrees, minutes and seconds at the end.
Happy for mom and dad and the kids! It so nice to have some millennials make it through all of the dead end traps our society has put in their way. Having taught preclinical dental classes, I appreciate your teaching style-understand the basics first, then demonstrate. Anyone who Ieaves a thumbs down is to be forgotten.
Great stuff Joe. I can see many applications to what you taught. I recently purchased a rotary table like yours and will put your lessons to work. Thankyou so much.
Joe, we went decimal in the 1960’s in South Africa, but still use DMS in most cases. Looking at other comments, it is fine to just use built in conversion functions on calculators or to use CAD to get the info, but surely it is good to know what the calculator or CAD program is doing and not just rely on the easy way out. Good job you’re doing
As a hobbyist, I went to trade school taking machine shop and tool and die making. I enjoy your instructional courses and have learned much from you and other tool and die makers on You Tube.
What do you do for work? I work at a shop (production) and don’t really like it but I lovvvvee the trade looking to switch careers for something that actually pays money
Joe, Congrats to your kids. Nice presentation on decimal degrees. I worked as a prototype machinist for some time. Always preferred decimal degrees. Too bad rotary tables etc. are stuck on the degrees minutes and seconds [DMS]routine. Somewhat like fractional drill bit sizes rather than decimal sizes. Huge pain in the brain. For those times when one must convert a decimal angle to DMS use a Hewlett-Packard HP-41 or emulator of said on your smartphone. Does the conversion with a built in function. You get to think in decimal and work in DMS this way.
congrats to the kids...besides being a great machinist/educator, your children prove your a great parent (and we know it can take two, congrats to your wife)....enjoyed
Great video and congrats to the kids! Former USMC Combat vet here. Hell of an achievement your daughter reached making Captain! Onto the rotary table question now...How would you accurately center an arc over the COR of the rotary table? I usually mark it during layout or center punch the center of the arc when i can, and use a dead center or other accurate conical tool in the spindle to line them up. Always wondered what a more accurate method would be. Thanks Joe!
Just about the right amount of detail. I didn't need a user manual to follow your presentation. It is unfortunate we are stuck with degrees, minutes, seconds. It would have been simpler to work in decimal degrees. I have considered making a new collar and vernier for my rotary graduated in decimal degrees. My Excel worksheet output is in decimal degrees and I have to convert to DMS to use the rotary. PITA. Please keep making videos. They are always great. Thanks.
@Donald R. Cossitt You are right. I converted radians to decimal degrees. That was easy. It took me a while to figure out how to convert the decimals to DMS.
Good video. I have a question for you. How would you set up an arc cut with a radius longer than the table on your mill? Say you have a part that is roughly 3”x6” but one side needs an arc that has a radius of 55”.
hey joe thanks for this precious info you gave to all of us... it was really use full... congrats to your children for their achievments... joe that rotary table does it take indexing plates to cut gears? if Yes can you do a video of how you cut gears and calculation...... I know that this is a vast topic on gears.. thanks karl from Malta
Joe love your videos learned a lot from you. I used to work with the old man that used to turn large radius on lathe by turning the desired radius on spare piece of material and then placed that piece onto the lathe somewhere not sure where I’m guessing on a bar set on the ways directly below the part set up a dial indicator onto that piece and he traced the radius onto the part he was cutting. I can’t figure out how he did it maybe you may know.
He also used to mill radius on parts on the end of flat bars by making a sub plate clamped in the vise with a dowel pin pressed in the plate then he would put the bar with a hole the size of the dowel pin located at the center of the radius desired, offset his cutter for the radius and would physically grab the bar and pull it into the cutter cutting the radius into the end of the bar. I’m still not sure how he did it. He did say to make sure you conventional mill and to use hss.
Nice video Joe. Could you do a follow up video showing the order of operations you would use to make that part. I am not asking you to physically make the part just number the steps on the board. Thanks
Its a world class facility. My oldest daughter Jackie is moving up through the ranks with her motorcycle and runs hot laps out there quite often. I go out to watch.
My daughter went on to be a Captain and recently received a masters degree in forensic chemistry. My son now works for Dell and is doing very well. I am very proud of my (3) children.
Hi Joe, I'm a newbie. I learn so much from your videos. Any chance you could show how to take these derived measurements and use them to mount the part on the rotary table to cut the arc. Cheers Bill
The lazy way to do it is to plug that drawing into a CAD program and have it give you the dims you're missing. I often use AutoCAD as a visual calculator like that. But it's nice to know the construction rules for when the power is out and all I have to work with is an 1800's book of trig tables.
Congratulations to Joe and Victoria, ... and to you Joe, for being the rock they stood upon to do so well in their endeavors! The solution to "all" of America's problems, is in having more Fathers like you......Well done video, and in watching it, it seemed suspicious to me that I have seen those measurements somewhere before ??? ...Eerily reminiscent of the heel of my long awaited project?.....(smiles) ..... I knew you couldn't stand it. I knew you would be constantly thinking about it in the back of your mind, like I have been for ten years, and that eventually it would surface to the frontal cortex of your mind and manifest itself in curiosity and being inquisitive about it.....Then you would think, "Where did that come from?" I found, as you move forward and deeper into it, it will consume your life and world, until you have beaten it. It did for me anyway. Don't you just love blueprints that don't have everything called out on them? and you have to "find" what they are trying to convey to you? An engineer once told me, that he thought the guys doing those prints way back then, were playing a sick joke on their colleagues by doing them that way. Case in point: As a builder, the first thing I look for on a house print and front elevation drawings, is the overall height, length, and width of the structure, and there it is! ...... but on the ones I am discussing here on my project, there are no measurements called out for those dimensions! You can't get there from here .....unless you know a guy like Joe Pie !!! ...Outstanding bud!
Like the geometry lesson. Used to be good at it in scool. I have a tricky one for you Joe. Can i machine an oval like the beam on a beam steam engine, with manual machines?
@@joepie221 You know, these model beam steam engines, considering making one from bar stock instead of buying castings. The beam may be 15" something long and 1.5" high. Nice elliptical shape. The outside would be easy to file or grind, but it should also have an inside shape following the outside. So we are talking two elliptical lines. One a bitt smaller than the other.
I'm a 43 year man and came up under a trio of old German Machinist if you had a German accent your explanations would be the same as my mentors. I'm mentoring a young man now and have been setting him down at the computer with your videos to help him learn the trade.

If we are talking about the same set, the insert holder arms give the clearance needed. Mine and many others are more of the conventional design for HSS tool bits. If you don't mind grinding your own tools, and don't require insert repeatability, I personally would just make one and save the money.

Hey Joe,thanks so much for taking the time to reply,I am really flattered.Joe,that said I am sorry I could not offer a model number to accurately identify the Suberban fly cutter I was referring to.I would understand that no one could really comment on an unknown object.Thanks again,I do believe you are one of the few that. Could quite your day job and go into teaching LOL.I must say again I have learned many things I have taken for granted or just was not aware.Have a great day and continue to enhance all your followers lives in such a positive way.Fred
@@fredechevarria3798 Thanks Fred. That means a lot.
Thanks Joe, this was very helpful.
Thanks for the review. Math minor in college, 100 years ago +-. Trig is the most useful everyday math. All those calculus courses I took haven't been of much use. I suspect the thumbs downs are from people that can't add &/or subtract. 9,152 views in 3 days says a lot.
I love geometry - no really! New to the rotary table and this information is fab, thanks.
I was a geometry wizard in high school. Loved it.
You throwing away .2 arc seconds gave me a good chuckle. Radio astronomers using VLBI will form images of objects spanning milliarcseconds.
The comparison of 60 minutes in a degree to 60 minutes in an hour and 60 seconds in a minute is a slick one.. As a civil engineer sometimes it is useful to use angles in decimals of degrees and convert to degrees, minutes and seconds at the end.
Happy for mom and dad and the kids! It so nice to have some millennials make it through all of the dead end traps our society has put in their way. Having taught preclinical dental classes, I appreciate your teaching style-understand the basics first, then demonstrate. Anyone who Ieaves a thumbs down is to be forgotten.
Great stuff Joe. I can see many applications to what you taught. I recently purchased a rotary table like yours and will put your lessons to work. Thankyou so much.
Joe, we went decimal in the 1960’s in South Africa, but still use DMS in most cases. Looking at other comments, it is fine to just use built in conversion functions on calculators or to use CAD to get the info, but surely it is good to know what the calculator or CAD program is doing and not just rely on the easy way out. Good job you’re doing
As a hobbyist, I went to trade school taking machine shop and tool and die making. I enjoy your instructional courses and have learned much from you and other tool and die makers on You Tube.
What do you do for work? I work at a shop (production) and don’t really like it but I lovvvvee the trade looking to switch careers for something that actually pays money
Sounds like you're a great parent and machinist. Congrats to all!
Thanks.
Thank you. Anyone thats done it knows being a parent isn't always easy. I'm blessed.
Great video and congrats on your children's achievements..
Joe,
Congrats to your kids. Nice presentation on decimal degrees. I worked as a prototype machinist for some time. Always preferred decimal degrees. Too bad rotary tables etc. are stuck on the degrees minutes and seconds [DMS]routine. Somewhat like fractional drill bit sizes rather than decimal sizes. Huge pain in the brain. For those times when one must convert a decimal angle to DMS use a Hewlett-Packard HP-41 or emulator of said on your smartphone. Does the conversion with a built in function. You get to think in decimal and work in DMS this way.
Sierra Nevada brewing is located in Chico , CA , and is not very far from those fires .
Excellent
If I had teachers like you in high school, I would be making fusion reactors now :-)
Thank you.
congrats to the kids...besides being a great machinist/educator, your children prove your a great parent (and we know it can take two, congrats to your wife)....enjoyed
Thanks Chuck.
cool lesson, thanks
another great lesson. Thanks. Congrats to your kids. do you use some kind of precision engineering calculations when getting a hair cut too??
thanks very much for the schooling Joe
Great video.Thank you.
Glad you liked it!
All of this time, I did not realize you were saying This is Joe "Pi". Now I get it! :) Euclid would be proud of you!
Congrats to your kids! Thanks for the tips
Thank you. I'm very proud of my kids.
Hey, congrats to your kids!!
Damn good time to be a Pie! Congrats!
Great video and congrats to the kids! Former USMC Combat vet here. Hell of an achievement your daughter reached making Captain! Onto the rotary table question now...How would you accurately center an arc over the COR of the rotary table? I usually mark it during layout or center punch the center of the arc when i can, and use a dead center or other accurate conical tool in the spindle to line them up. Always wondered what a more accurate method would be. Thanks Joe!
Thanks, and thank you for your service as well. I'll show the centering in upcoming videos. Got some very cool tricks.
Nice shirt. One of your awesome kids must've given that to you. :) Love you, Dad. xoxo
Hi Punkin. I love you too. Thanks for checking in.
VERRY GOOD INFORMATION
I still have my AE-1 Program from the 80's. Have the autowinder for it too... :-)
Nice video, really nice content.
Many people struggle a lot with sine and cosine, to figure out dimensions on let´s say a little odd shaped parts.
Just about the right amount of detail. I didn't need a user manual to follow your presentation. It is unfortunate we are stuck with degrees, minutes, seconds. It would have been simpler to work in decimal degrees. I have considered making a new collar and vernier for my rotary graduated in decimal degrees. My Excel worksheet output is in decimal degrees and I have to convert to DMS to use the rotary. PITA.
Please keep making videos. They are always great. Thanks.
@Donald R. Cossitt You are right. I converted radians to decimal degrees. That was easy. It took me a while to figure out how to convert the decimals to DMS.
OK Joe. You have convinced me. I should have paid attention in Geometry Class. Unfortunately that was not the case.
Thanks Joe
Good video. I have a question for you. How would you set up an arc cut with a radius longer than the table on your mill? Say you have a part that is roughly 3”x6” but one side needs an arc that has a radius of 55”.
You would have to use out riggers! I managed to do a 350mm radius on a 8 inch rotory table.
Hello sir, this is my first comment for you. all the information contained are useful and interesting thunks for sharing.good luck.
I'm from Algeria
Thanks for the comment and for leaving your home location. Its good to know how far these videos go.
hey joe thanks for this precious info you gave to all of us... it was really use full... congrats to your children for their achievments... joe that rotary table does it take indexing plates to cut gears? if Yes can you do a video of how you cut gears and calculation...... I know that this is a vast topic on gears.. thanks karl from Malta
Joe love your videos learned a lot from you. I used to work with the old man that used to turn large radius on lathe by turning the desired radius on spare piece of material and then placed that piece onto the lathe somewhere not sure where I’m guessing on a bar set on the ways directly below the part set up a dial indicator onto that piece and he traced the radius onto the part he was cutting. I can’t figure out how he did it maybe you may know.
He also used to mill radius on parts on the end of flat bars by making a sub plate clamped in the vise with a dowel pin pressed in the plate then he would put the bar with a hole the size of the dowel pin located at the center of the radius desired, offset his cutter for the radius and would physically grab the bar and pull it into the cutter cutting the radius into the end of the bar. I’m still not sure how he did it. He did say to make sure you conventional mill and to use hss.
Proud Dad Joe :) Best regards G :)
Nice video Joe. Could you do a follow up video showing the order of operations you would use to make that part. I am not asking you to physically make the part just number the steps on the board.
Thanks
Another excellent video Joe. Cool shirt by the way.. I hope to attend a MOTOGP event there soon. Maybe I'll stop by the shop and say hello.
Its a world class facility. My oldest daughter Jackie is moving up through the ranks with her motorcycle and runs hot laps out there quite often. I go out to watch.
Great common sense and straightforward as always Joe, a couple of years late, but congratulations to your Son and Daughter sir
My daughter went on to be a Captain and recently received a masters degree in forensic chemistry. My son now works for Dell and is doing very well. I am very proud of my (3) children.
Outstanding Joe x
Thank god I built me a little CNC cutter. That maths was WAY to advanced for my feeble brain! :)
Hi Joe, I'm a newbie. I learn so much from your videos. Any chance you could show how to take these derived measurements and use them to mount the part on the rotary table to cut the arc. Cheers Bill
Coming right up.
Joe great video. I've always loved geometric construction too. Do I get any extra credit for the answer being .224?
I am actually going to make the cut in the next video. Congrats on doing the math.
The lazy way to do it is to plug that drawing into a CAD program and have it give you the dims you're missing. I often use AutoCAD as a visual calculator like that. But it's nice to know the construction rules for when the power is out and all I have to work with is an 1800's book of trig tables.
Congratulations to Joe and Victoria, ... and to you Joe, for being the rock they stood upon to do so well in their endeavors! The solution to "all" of America's problems, is in having more Fathers like you......Well done video, and in watching it, it seemed suspicious to me that I have seen those measurements somewhere before ??? ...Eerily reminiscent of the heel of my long awaited project?.....(smiles) ..... I knew you couldn't stand it. I knew you would be constantly thinking about it in the back of your mind, like I have been for ten years, and that eventually it would surface to the frontal cortex of your mind and manifest itself in curiosity and being inquisitive about it.....Then you would think, "Where did that come from?" I found, as you move forward and deeper into it, it will consume your life and world, until you have beaten it. It did for me anyway. Don't you just love blueprints that don't have everything called out on them? and you have to "find" what they are trying to convey to you? An engineer once told me, that he thought the guys doing those prints way back then, were playing a sick joke on their colleagues by doing them that way. Case in point: As a builder, the first thing I look for on a house print and front elevation drawings, is the overall height, length, and width of the structure, and there it is! ...... but on the ones I am discussing here on my project, there are no measurements called out for those dimensions! You can't get there from here .....unless you know a guy like Joe Pie !!! ...Outstanding bud!
Thanks Rick. I enjoy a good challenge now and then.
A straight line that becomes an arc is a loxodrome. A tangent merely touches the arc.
Like the geometry lesson. Used to be good at it in scool.
I have a tricky one for you Joe. Can i machine an oval like the beam on a beam steam engine, with manual machines?
Depends on the upper and lower radius size. I'd bet we could figure out a way.
@@joepie221 You know, these model beam steam engines, considering making one from bar stock instead of buying castings. The beam may be 15" something long and 1.5" high. Nice elliptical shape. The outside would be easy to file or grind, but it should also have an inside shape following the outside. So we are talking two elliptical lines. One a bitt smaller than the other.
