I felt like I was in a class room with a very knowledgeable teacher that is very talented at teaching!!!
I have seen a lot of bevel gears and not realize much is taken into account to cut them. Thanks for the explanation into the cutting, well done.😊
I’m not a machine shop guy but I love watching milling machines and people put their skills to work restoring things. When I saw you cut the initial casting I was hooked.
Saw someone on another channel asking for help printing a bevel gear. He couldn't stop it from binding. Now I can see why. Thanks for the great explanation of the tooth geometry.
Having cut bevel gears on a horizontal mill myself, I can vouch for the attention to detail required to make these gears.
Nice job. My take on this subject is don’t be afraid to take it on, just do your homework. I’m starting to sound like Keith. 😁
Thanks Keith,
John
I only have a small vertical mill, but it has some degree of rigidity ...but certainly not a two ton Cincinnati. At least a box column. Very impressive video. I recently made my first spur gear reduction to replace a very awkward hand crank on the side of a vertical milling head machine. Gear reduced 96:15 ratio ...an estimated ratio ...and lucky me, the ratio turned out almost perfect. I simply attach a cordless hand drill to an input shaft and let the drill raise and lower the head. I planned ahead to reduce more if needed in the gear frame mechanism ...but it wasn't needed. As it was a first attempt, and spur gear was the "easiest". I was interested in looking into a bevel gear design to have the input shaft pointing forward toward the operator. Your video answered ALL the questions! Thank you very much for sharing your knowledge and time. ------ I am thinking I might like this new challenge!!
I respect your honesty, and admire your craftsmanship.
Outstanding work.
Take care.
You explain things so well. I'm no machinist, but I could understand everything clearly.
This was the first bevel gear fabrication I have seen so this was a good subject. Well done Keith!!!!
This is great! I enjoyed the math and attention to detail. Your amount of homework put in is clearly evident. Thank you Keith!
Thank you Keith. I really appreciate the look over your shoulder to see such amazing projects.
Im not meaning to talk bad about other channels, but this channel consistently makes me feel like ive learned something new. Thoughtfully explained, wonderfully filmed, by a guy that is humble as the day is long. No wonder i get excited everytime i get a new video notification!! Best machining channel on UA-cam!
Great explanation, actually wrapped my head around it. Well done.
In the age of 3D printers, this video makes me appreciate the maths and tradesmanship behind the bevel gear. Thanks Keith.
I like your teaching style, Keith. I don't have dividing head or horizontal mill, but I have a vertical mill and was mentally converting your setup to what I'd need to do in the other direction.
That's a pretty impressive result for your first time. Congratulations and I appreciate your honesty and sincerity as you explained this difficult operation. Well played.
It's now easy to see why gear hobs are used to form gears like this. An excellent job, Keith. Many thanks.
Bevel gears are actually not hobbed. Each tooth is cut individually like this ua-cam.com/video/QTlo6bIIieE/v-deo.html
Keith, you sure made that look easy! Great job!
This was super interesting. I guess I never thought about the fact that a bevel gear tooth had tapered faces. Well done Keith for a great explanation and some good footage of the cutting stages.
Keith you are a Master of your craft, I could understand some of it (not being a machinist) but got lost about 3 minutes after you started explaining the angles of cut. It can out great, can't wait til it's finished. Thanks for sharing and stay safe.
Gday Keith, you did a great job explaining the makings of a bevel gear, I really need to get a machinery’s handbook, there is a lot of maths that goes into this and sadly mathematics and I don’t tend to mix, I appreciate the effort you go to to help people like me understand how things work, thank you, Take care. Matty
That’s a good result Keith. I feel like I could do it too. Thanks for sharing.
Like every machinist, on occasion I get questions about what a machinist does. And I try to explain what it is that I've spent so many years of my life doing and I'll get comments from different people to the effect of, "well, that doesn't sound so hard, all you have to do is set the machine and it does the work!" From now on I'm going to send them to your channel and let them see for themselves just how much work and effort has to go into a machined part like this one you just did. Wonderful work Mr. Rucker, well done.
Keith, Awesome video and content intriguing to also watch, thanks for sharing your video.!.!.!.
Keith, like you I've cut many spur gears repairing lathes and other machines. But bevel gears, ugh! I have a beautiful 1897 Flather lathe and a nice adjust-tru chuck that have been waiting for me to cut bevel gears so they can get back to work. Your "course" has given me what I needed! Thanks for your wisdom and insight. Can't wait to get back to the shop and get these two bevel gears cut!!
Super video, very educational and insightful, bevel gears are so useful and undervalued. Really appreciate your take on making them.
Keith, you are The Best Teacher on UA-cam.
That was brilliant kieth thanks for posting all your films it learns me a hell of a lot and I’m 64
Wow🤔, probably the highest challenging task yet. Well done! Thanks for allowing us to look over your shoulder and the well though out description of the complexities.
Now I am convenced I NEED the handbook👍👍👍👍
Keith, Never cut a bevel gear before, but also never thought it was any big deal. But watching you go through the steps I now realize that its a bigger deal than I thought. Thanks for sharing. And maybe its time for me to get one of those fancy machining hand books :) Gary
I admire your sense of learning and your persistence.
Nicely presented. As a non-machinist, I was able to understand you and appreciate both your explanation and the fine job you did with old machinery making what appears to be a very serviceable bevel gear. Good Job!
Thanks Keith. Appreciated the step-by-step explanation and good shots in the mill.
I didn't understand half he said at the beginning, it was to technical for me . But later in the video I understood more. When he actually started making it. But I never knew there was so much to making bevelled gears . A very well made explanation of a very complicated subject !
Great video discussion/demonstration/build
I went through this 30 years ago, using similar equipment like you did. You are right, to understand what and why you do it is more than half way. About 5 years ago I made a bevel gear on a 4 axis CNC using ball endmills - that was in comparison really easy.
I have much respect for the effort and talent you put into this rewarding project. Thank you for sharing this.
Oh man! I need to build 1 if not 2 in the distant future for a wringer washer. Good video to start out on
Great 👍🏼 job Keith! I have cut a lot of different configurations never had to get really involved in gear cutting. Your general public has no clue what a machinist has to do to calculate completion of an operation. I have been blessed to work I. The manual machine side. NC machinist use to be what the industry was always looking for. I understand the logic for high speed production. But as soon as they know you have manual skills your gold and you get all the problem projects!! Keep the great videos coming!
Remember those calculations are very OLD! Those old machinists really did their homework way back in the day. No CAD or computers either. LOL
Lee Klemetti very true! Growing up we always thought our parents were clueless! They had more cognitive thinking going on than we can imagine! My machinist handbook saved my butt several times! My dad was a carpenter, he also had what he called his carpenter bible. It had all types of calculations. Pitch and rise, footings and foundation load calculators tons of structural formulas. Even though the engineer has already done it. The old timers validate everything! Be blessed!!
Nice job and excellent explanation! And as the saying goes the parts just need to get used to each other. Thanks for all the videos.
An intense segment, well done !!
Good Job Keith, Learning as you go, That's Great!
One step closer Keith. Cant wait to see it all finished.
That was great, your quite the teacher, I’m learning more and more through your channel
Very good explanation and demonstration on cutting bevel gears. One of your more interesting videos.
Very interesting Keith. I had no idea how this would be made so watched it with great interest.
Nicely done!
There's a lot more to bevel gears than I'd ever thought. Thanks, Keith!
This is why I watch. Great machining, and interesting parts to be machined. Keep up the good work.
Thanks for posting this video. There is a real dearth of information on bevel gear cutting and this helps a lot. Of the many things I learned probably the most important one is that if you can find an off the shelf bevel gear for your application it will probably be cheaper than trying to find the cutters and do all the work to make one, unless you're just up for a challenge. If you can't find a proper gear you don't have any other choice. Thanks again!
Great videography, Thanks.
Love watching the last tooth line up perfect cheers from OZ.
Beautiful video work too. Seeing the profile of the gears appearing was pretty hawesome.
Keith you make great...Videos l could watch you work for hours....Thank my friend....Blessing you way for sure....!
Great little video
That was very interesting - I had no idea how to mill a bevel gear. Thanks for the great video.
Thank You! Very informative and well explained.
Thanks for sharing, I enjoy watching gear cutting.
Amazing making
Keith, I think that was your best video ever! Learned a lot, as did you apparently. Thanks.
Great tutorial and great hands on step-by-step. Thank you. Great videos Keith.
Nice job. Quite the learning experience.
Seriously impressive work Keith..
Great work Keith thanks for sharing
Very tricky but you did a great job........well done!!!
Nice job. The word tame got my sub.
Keith,
I’ve only ever cut spur gears, both involute and a different tooth form for clocks, and haven’t touched any machine tool since 1990 when I moved to a new workplace and lost access to workshops.
Interesting to compare the cutting of this bevel gear to the helical gear which you did more recently. The helical gear was quite simple; it took a lot of time and different videos, but most of that work was in finding or making missing, broken or incorrect parts. There was also the need to use the universal head due to the large helix angle of that gear. Now you have everything set up cutting another helical gear would be a fairly simple matter.
The bevel gear is more complicated to set up. I then thought about whether it would be possible to combine the two techniques to cut a spiral bevel gear on a horizontal mill without needing a specialised machine. Looked on UA-cam and there’s a video of somebody doing it; looks like they’re using a fly cutter. Amazing what you can get a horizontal milling machine to do.
Have noticed that both of your dividing heads have two handles, the one with the plunger pin to fit the holes in the index plate and a plain handle. Obviously you couldn’t turn the plain handle while the pin was engaged in the plate, and it would be difficult to hold the pin out with one hand while turning the plain handle with the other. Is it possible to lock the pin back while turning the plain handle? This would seem like a good idea but I’ve never seen it on any devising head that I have used.
Can either of your dividing heads do differential indexing? Might be useful on the k type with it’s 5:1 ratio where you might need to turn the handle by a small amount to index a large number of divisions.
I had never heard of K&T until I watched your videos. Do you have a copy of one of their catalogues showing all of the various attachments they made? If you do it would be interesting to see a scan of it.
Best wishes.
Great job at explaining everyone needs to do there homework on every project
Excellent demonstration and explanation, thank you!
Excellent work and explain
Impressed from Gisborne New Zealand.... keep up the good work
Awesome! Hope to accomplish that in the future myself !
Really enjoyed this video. Thank you for your time. Really easy to listen to. Like you I've cut a good few spurs but no bevel. Great to see. Thank you.
Super video and very understanderble from a semi technical point of view - thanks!
Fantastic explanation, including the differences between this approach vs an actual gear hob.
Looks great!
Wow, complex! As always thanks for posting.
The Best video on making bevel gears !
I think this makes you a master craftsman.
Keith, That was a very interesting Process, Thanks for sharing.
Good video :-) Very fascinating to watch you break new grounds. I liked the “Do our homework” emphazis.
Thanks Keith. That was very informative, interesting and entertaining.
The only thing that was missing was a close up of the finished gear so we could see the profile of where that second and third cuts were.
You can see the cutting angles on the gear when he showed the two gears mesh together. Nice job Keith.
Great video. Very educational. Thank you.
Thanks for the lesson
Nice job. I have never tried to cut a bevel gear either. For what it’s worth, my arbors also have some runout. Even when I run a slitting saw on my Bridgeport it seems like only a few teeth on the saw are doing the bulk of the cutting. Stay healthy.
Learn something new thank you .
Well Done, The first of many, we hope.
I enjoy your efforts and I am impressed. I cannot understand the negative reviews though. You inform you are learning. I take that as "this is what I offer and present your process in learning." I am a novice and appreciate this and get confused as to shadow nay-sayers reckoning enough to do this. (Long time follower)
Love your videos recently discovered them! All that angle mess must be good for avoiding alzheimer's. greetings from Argentina
Looking in you publications data base I saw in a illustrated accessories list where a "thinner" (like the support on the end of the arbor), was placed on the machine with the cutter placed at the halfway point between the two supports. I believe that would straighten out the arbor and eliminate the runout.
This is what metal working is about. Look it up, study it, try it out and go for it 👍🏻
Great work, great video. Just watched another video showing the same, bevel gear cutting. Keith is explaining the theory and showing "how to" a lot better.
How about making the +5 degree cut and then -5 degree cut and file the bottom?
Just finished and verified a digitally controlled rotating table having the resolution of 2.25 seconds.
Gear cutting is waiting but what kind of gears is yet to be known..... Bevel gears looks like demanding a lot especially the 3 step method. Future will tell....
Awesome job i will be scratching my head another 10 years or so and may try it then !!
I admire the draftsmen who made the illustrations in the machinery's handbook without 3D CAD
Life wasn't so bad with descriptive geometry
You should see the illustrations in one of the books I have in the workings of Steam Engines and Injectors
I have 2 books of the set of the books from a class on Railroad Steam Engines by International Textbooks in Scranton PA
From back in the days when classes where done by mail for some courses when people want to learn but did not have the time to attend a classroom-type of school
they didn't do it freehand, they used all sorts of mechanical devices for drafting, as well as tracing shadow boxes
Thats when people used there brain and not a computer
@@timsering9964 Took 3 years of drafting in HS along with 2 years of electronic, Love how people today CANT read a Blueprint. the classes were Vocation Education. BTW went in the field of computer repair
Great job
Any way you see it, this complicated little job is impressive to no end.
Good morning from St John Parish, Louisiana.
I have been anxiously waiting for this video.Seriously appreciate this one.👍
