Very satisfying watching the layout die removed as you cut each tooth. Gotta like that Hardinge dividing head, Tubalcain
The more I watch your vids the more I appreciate your great skill and patience--Thank you.
I appreciate that!
Mr Pete = a positive side of social distancing! Thanks for helping to make math equations more relevant.
Hey Mr Pete-you explain not only what the project is but what mistakes I should look for. Your “re-Pete” idea is fantastic !!
Thanks
Great stuff, Mr Pete! I like using Dykem red. It hides the blood when I cut myself on the work piece ;-)
lol
Got you beat, I just use the blood. :op
Mr Pete, Just an Idea but have you ever done a video about how you got started being a machinist including your time as a shop teacher, not trying to put you on the spot here but I think your viewers would like it.
nice to see the little Bridgeport is in the picture as well
Sat night in Australia and I’ve just watched 18 cuts when I’d usually be watching 70s rock on Utube😆 Precision cuts Mr Pete.
Thanks
Thumbs up, you really are the No.1 You Tube shop teacher.
Thank you very much
Lovely... always a joy to see your projects.
👍
Saturday morning quality time aka Mr Pete 👌😊 Thanks for the entertainment Mr
I always enjoy when you guys show us how you word the dials
Great content as always Mr. Pete
Nice work. Love the stories from your teacher days.
I wasn’t allowed to do Metal Shop at school. I went on to be a Fitter Machinist. Whoops :)
Great work. Very edutaining. Gotta get me a dividing head, cutting gears is something I plan on doing. Very Helpful video. I thought more of my High School machine shop teacher than any other. He was a great teacher who be came a friend when I got older.
Many people liked their shop teachers. And that is very gratifying. Not many people liked their English teacher
I know this is a older video but it's really great information! Thanks mr pete
Thanks
I used your method to center the cutter, if it is a large tooth profile, I lock the quill up and use the elevating crank to center the tool. I then made a cut across the face, put magic marker on the cut, turn the indexing head 180 degrees, and take the cutting pass again. If the cutter is perfectly centered, the cutter will remove some or all the magic marker on both sides of the cut. If the second cut only takes material off one side of the cut, I use the elevating crank to fine tune the cutter position.
i still do not see how any body can give these or any of the communities machining videos a thumbs down it just pisses me off sorry for the rant keep up the good work Mr Pete
Yes, they are hurtful and love it
@@mrpete222 Mr Pete you are the teacher every boy i grew up with would have loved to have, i have learned so much from you and the community
Threading and gear cutting are the two most fun machine shop tasks. Thanks for another great video.
Yes
Mr Pete, I'm a long-time subscriber. I've been meaning to send you a direct thank you for your videos, but I'd also like to say you mean so much to a lot of folks, so please stay safe and keep isolated! I'm sure a man who values safety, discipline, and doing the right thing will not need to be told not to cut corners with safety, or that the dangers are deadly serious, but I feel I needed to share. ERs and ICUs are now full of people who didn't think they were taking risks. This virus is sneaky and nasty.
I'm a molecular biologist, and I probably will never set up my own machine shop, but I've been enjoying your channel for years. In an age of uncertainty, your videos showcase precision, exactitude, and craftsmanship. Your videos are more than just how-to's: they are a window into a world where the parts fit, the right tool for the job is at hand and in its proper place, and all the measurements line up. Now more than ever, this is needed.
Even in the best of times, we've become accustomed to cheap disposable crap made in far off lands, and there's something pleasurable and reassuring to see things made with care to both the process and the finished product. Please keep up the good work. I wish good health to you and yours!
Thank you very much for the warning. Because I haven’t taken this thing very seriously. At my age I do not worry too much about dying since it is inevitable. I enjoyed your comment it was very touching. I really wish I would get more views, because I have been getting discouraged lately
Another interesting and instructive video. I pickup machining tips each time I watch one of your videos. Stay well and take care..
Thanks
The 1st time I cut a gear I miscalculated setting the cutter center so my teeth were all leaning horribly to one side. How fun! Needless to say I learn my lesson there.
You sound like my dentist, is your name Rob?
@@MrUbiquitousTech Sounds like you need a different dentist. Preferably one who doesn't sing...
Dentures & fillings & missing tooth faces,
Root canal problems & tightening braces,
Brown yucky tartar that won't get too clean,
These are a few of my favorite things.
When the tooth aches, when the gums bleed, when I'm feeling pain,
I simply remember my favorite things,
and know that I'll go insane.
Pustules & boils & festering rashes,
Tumorous swellings that turn into gashes,
Gangrenous digits that blacken & sting,
These are a few of my favorite things.
When the sores bleed,
When the pus runs,
When I'm dripping ooze,
I simply remember my favorite things,
and then I don't need my booze.
@@ExtantFrodo2 HAAAAA! Well done! ;o)
Thanks Mr Pete for another great video, looking forward to the final part in this series. Hope you and your family are well in these troubling times.
Great video,reminded me of my high school shop class where we cast a brick sized block of aluminum and made a rack and pinion press that the teacher called it a nut cracker cria 1964.Will
Saturday is off to a great start. Thanks, Mr. Pete! :-)
Good Morning Mr. Pete, Good show old boy Time for coffee.
Always some awesome content mate. Thanks for sharing
Thanks
Well done... can't wait to see video part #4. Best regards
Mr.Pete way better than Saturday cartoons,lol great video thank you!.
Hello mr Pete, thanks for sharing your interesting video, look forward to the next one.
Thanks
Excellent, I really enjoy the process.
Love these videos!! I really fancy matching up some half shaft for my elderly Land Rover!! 🤣🇬🇧
👌
I have no use for one of these machined parts Mr Pete but I sure love your teaching style.
Mr. Pete, many thanks for all of your dividing head videos! I have the same little Hardinge as you and really enjoy using it. I’ve used the social distancing period to make a rack and pinion gear for my bassoon reed machine, using your advice. I’ve also been rebuilding and making parts for an old NIchols Horizontal Miller. Lots of peace and quiet and good fun in the basement!
My shop is my sanctuary. Basoon reeds, That’s a good one most people do not even know what that instrument is.
Great work mr Pete
Mr. Pete, I may have been one of those boys in shop class with a less than perfect project; however I don't remember that thankfully for a conveniently failing memory...lol.
lol
Job well done. Time to make a small arbor press. Stay Safe and well.
Yes Randy it has already been made. Videos available in about two weeks. Very nice job on your second video on bearings. Your photography is exquisite
@@mrpete222 Shoot I was just guessing. Nice. Thank you.
Love it! Thank you Lyle. You always make things look so simple. NONE finer!
you area great teacher to rate fantastic :)
Thanks
Thank you mr Pete for another great video. You kinda remind me of Paul Harvey, used to listen to him all the time, thanks stay safe
thanks for sharing at 80 yrs young I love the older ways!
I also used a shadow graph for my cutter pitch and a chart for the dividing head and plate.
Great video once again!! You are a Great teacher!
a great video Mr Pete
Awesome video.
Great work. Mr. Pete. Thank you for explaining the process in great detail. Thank you for sharing.
Mr. Pete i 'm glad to see you using a Hardinge indexer as that is all the shop i work for has we have 6 of them and that all i know till i saw others on you tube
Great to watch something interesting and positive besides the Crona virus 24/7 while locked in at home. Thank you Mr. Peterson.
This series is real interesting.
Good morning Mr Pete thanks for teaching me another great lesson I always learn something every time I watch your videos thanks for what you do
👍👍
Another excellent video sir, thank you!
Really liked it a bunch. I'm fascinated by the entire process of gear making. I've never tried, one day...Great video!!!!!
Thanks
Excellent explanation and masterful demonstration.
Thank's Mr. Pete for the educational content. Keep it coming!
👍
Some years of skills in this video, very good straight forward lesson and not to long either, I dont like hour long videos. Thanks for sharing your knowledge.
Nice work Lyle, thanks for sharing
Thanks again Mr.Pete, for your good knowledge and videos you share with us,we all appreciate your wonderful work,good morning and keep safe,coming from one of your students from Trinidad in the Caribbean.
Good morning
Good morning, Me Pete! I don't know why but I always like watching someone cut gears whether it is on a vertical mill or a horizontal. Great video and explanation.
When I saw the 6" Craftsman scale I paused a bit-I had found one last weekend while cleaning out an old Craftsman tool box that was given to me. I had to go out to the shop and get the scale to check the model number-yep-same scale. I had to clean it up-years of rust dust, dirt, and some gooey substance that was in the top section had it looking rough. With a little Scotch-brite and some lacquer thinner it came right back. The edges and numbers are still crisp and the only blemish (if you could call it that) is where the previous owner has engraved .030 near one end. Just by eyeball I'm assuming that is the thickness but I haven't confirmed.
One of my hobbies is woodworking and I find I use the 6" scales more than any other ruler I have. On the small boxes (and most projects) I make they are a lot less cumbersome than the 12"s. I have a few 6"ers-a couple Starretts, a Brown and Sharp and now the Craftsman.
Have a great day and stay safe. This goes out to everyone in these crazy times.
That is one of my favorite scales. I do not remember where I got it. Very high-quality
I do mostly cnc/cad stuff but still get to do a good bit of manual work since it's more of a job shop. I love trying to get better with doing old school stuff since I don't do enough manual on the job to get to learn to hate it.
👍
Great! Thank You.
Dad would have loved the channel
Jim
Thanks, Lyle. Right to the point, and very helpful.
Two thumbs up and a comment to feed the algorithm.
Good morning, Mr. Pete.
Thanks
Thoroughly satisfying.
Thanks Tubalcain. :-)
Thanks for the Saturday morning video sir....
THANK YOU...for sharing. Liked it very much.
The virus lock down isn't all bad; I am using the time to finally learn more about my mill and Atlas lathe. Swapped out change gears and changed the feed rate last evening for the first time. Thinking I will finally build that wobbler motor...
👍👍
Very nice , thanks for showing us how it’s done .
Nice work
Thank you very much, Im always learning with your videos plus I like so much the old school rather now CNC machines. Best reggards from México.
The manual machines are most definitely more interesting, obviously though CNC is the way to go for production. Manual still has its place though in repair parts and one-ofs.
Thank You Lyle !!!....You have made clear, wonderful, instructions....Last week I happened to make an 18 T brass spur gear with a 5 deg. angle set at the center of the gear blank at home for replacement for the warn out Clausing Lathe Rapid Feed attachment. I did not have the correct cutters so used a hand ground carbide fly cutter. The gear also had two 1/8" holes offset holes to align the gear. Everything worked fine BUT I need to purchase a set of correct cutters for a more accurate gear and to have backup gears...TM
Sounds like you did an awesome job
Wow... One of your better videos....
Thanks
Thanks for sharing Mr Pete ( stay safe ) 🇦🇺
My nocturnal shop teacher
I've cut a fair number of 80 and 88 tooth mod 0.8 metric gears on my little mill in delrin, a tedious task indeed. But certainly a skill I'm glad I've performed.
Yes
My Saturday Fix! Thanks!
Thank you for another great video, I always learn something new.
Always awesome, Mr. Pete!
Great Teacher!!!
Enjoyed, as always, your videos. Thank you..!
Nice job
At Plainfield HS back in the 70's, we didn't have a milling machine. An arbor press would have been a fun and useful project.
Good instruction as akways. Thanks
Thanks for wonderful videos ,
Please keep it up ,,
I always thumbs up because .....well I liked it !
👍
I was one of those students when I took my machine shop class we had to cut gears we were given plans and dimensions and told to go build the gear..The first gear I did did not come out equal in it's dia.. and I had to go redo it. But I also learned the reason why and never did it again
👍👍
Thanks Mr Pete.
Hah! What a coincidence! I'm currently designing a machine that needs a 24P/18T (20PA) gear on a complex spindle with limited axial clearance to features on both sides. I clicked on your video just to understand the machining issues of gear-cutting, and your video simply answers my questions 'to a T'! I was hoping to find a cutter with an OD that's as small as possible so it would allow minimal axial space along my part for access, but couldn't find a cutter diameter less than 1.75 OD! Anyway, I was surprised that you could machine each tooth with just one pass of a cut. You made it appear simple!
How much time did this job take from set-up to final cut & verification?
One hour. Thanks
Two thumbs up not one Great enjoyed
THHANK YOU MR P.
Mr Pete If possible Kindly post video on Surface Grinding
I do not own a grinder
Snyggt jobbat pete!!
Thumbs Up
Thanks for another great video, my only beef is that you mute the sound whilst machining. I think that the sound makes it a lot more personal, you can imagine being in your class when the sound is on.
When i saw you said pinion i was thinking it would be neat to see the inside mating of a pinion spline in a hole made for it. That seems to me a real challenge. its not like cutting a key way so I'm wondering how one would go about doing that? and how to index it too. My interest is in mating electrical motors to transmission shafts with a coupling.
Mr Pete. Great video. Thank you. Question: have you ever done this using a rotary table rather than a dividing head? Any videos in your vast library that shows it? Thanks again 😊
Not yet!
Thank you Mr Pete.
I know this project is probably already finished by the time I see it, but you could turn it in to a nut cracker and then it would have a purpose.
Thanks
Don’t get ahead of me, that’s coming
@@mrpete222
Sorry about that. You can hide my comment if you want. I won't take it personally. Thanks
i drafted a cvt for a cadillac, now i know how my parts were made.
Anyway to cut gears without a dividing head on the Bridgeport?
Should be no problem; here is how I’ve done it. You will need to create your own indexing plate for your gear blank. Let say you want a gear with 52 teeth with a DP of 18. Make your OD of your blank 3”. Now using basic trigonometry, make a hole pattern (52 holes) with a 1/16” drill bit a ½” from the outside edge (that would be a 2” circle), do not drill all the way thru. Now holding the center of the blank steady on top of your vise, you will use the 1/16” holes and a 1/16” drill bit to index your blank. You can make two blanks and hold them together with double sided tape; using one as your indexing plate.
Liked It❗
Hi Lyle, Thanks for this series, it is very helpful. I hope all is well with You and Your's. QUESTION on your "Mutilated 3 Jaw Chuck". Now, I know you've already done lots of chuck videos but not, I think, like this. Could you show us how to cut down those jaws and make them into Master Jaws, then you could make new sets of Soft and Specialty Jaws which could be made to run true? Stay Safe and Well :)
See you next time! :-)
