Homemade Gear HOBBING Machine

[@bigbossimmotal]

I absolutely love watching Uri perform his craft, a comic genius, a world class artist, a rock star, and a mad scientist all rolled into one. It makes me feel a bit like we are getting a peek into the minds of the greats like DaVinci, Michelangelo, and Monet, and what it would be like to spend a day in their shops. Thank you Mr. Tuchman, you are greatly appreciated by so many.

Would love to see him work with this old tony or perhaps even AVE but I'm worried of the consequences haha

Is AvE still relevant? I heard he went full MCGA during the c*vid n*zi convoy debacle. Besides I don't think someone who writes "Art" on his trash bin would be a too suitable collaborator in this particular context.

I would love to see Yuri collaborate with himself on a project. One of them could explain why he chose the particular material while the other could do the actual making.

[@travisrickett8271]

I'm going to be honest Uri, the entire video I had no idea what you were actually making, but I was mesmerized watching you make it.

[@BuriedAliveBySquirrels]

I'd probably add a second support to reduce vibration and then add a pin to hold the tap at the other end...if I were so motivated. Watching your videos makes me wonder what I, an engineer, am even doing with my life.

[@rockaholictom]

5 am in Ireland and I don’t even care, Uri put out a new _delicious_ video

[@robertlangley258]

I have nothing intelligent to say but would like to say: I enjoy watching Uri do anything he desires as to me he is a mastermind. He has a way with words, is very funny, makes great videos and presents himself in a friendly manner while sharing his genius in designing and producing works of art. I wish I had some words of wisdom on improving this hobbing apparatus but alas I get challenged making a funnel out of a sheet of paper.

[@peterpan7903]

The milling cutter used to make the gear is for a hobbing machine. In such a machine, there is a fixed connection between the tool axis and the workpiece axis via gear wheels. These are changed according to the number of teeth required. When the cutter rotates, the workpiece rotates with the pitch of the cutter. Then only the cutter has to be moved axially to the workpiece axis. This then produces straight or helical-toothed gears. The simpler, cheaper method of producing gears is with a dividing head or dividing disc and a disc cutter with the necessary tooth profile. There are different profiles for different ranges of tooth numbers. However, this can only be used to produce straight-toothed gears. Watchmakers produce missing gears in this way. With the oiler, I would also put wool threads in the hole up to the lubrication point. That's how it's done on old machines.

[@BrotherHoodMovies331]

I think the best shout for the old watchmakers lathe would be to turn it into a lapping machine, something you can polish the heads of tiny screws with, maybe even sharpen gravers on, something like that.

[@ferdblu1946]

Great idea!

[@nobuckle40]

Uri, it doesn't matter if it works or not. You make some of the coolest stuff in the world. If you would be willing to, it would be a pleasure to learn how you came up with the design.

[@urituchmanpigeon]

Thank you! Though it's not my design, gear hobbing is well spread and many other people have done similar stuff in their shop, I took the inspiration and made my own version.

[@cuzuman]

A hobbyist lathe? I desperately need one. Sir you are a genius.

[@WhatTimeIsIt369]

Accidentally found this channel. I love it when people aren't particularly good at things, in this case machining, but they do it anyway and can end up with something viable in the end. This is a great example of a hobbyist that does things for the sake of loving to build things. His humor cracks me up.

[@johnkennedy2505]

The oilers I have on my lathe have a piece of felt in them just like the lubricator on a old points distributor. If the cotton flows too much oil i would try a filter from a cigarette.

[@berserkir]

[@jasone3166]

It is amazing to see another person who likes to make things but puts form before function. I am the proud builder of an electric motor that looks like it was made on 1905, but it doesn't work. I believe that people like Uri, and myself, want to create beautiful functional pieces so we spend many hours making it look good, and hoping like hell that it actually works. Sometimes, it doesn't, but man, it looks good!

[@samanthadean1083]

Uri has a new video up!!! Enough said!!! ❤️❤️❤️👍🏻👍🏻👍🏻

[@coleanderson9731]

I clicked this so fast. Love the videos Uri!

[@SilentDreamer45]

I’ll never forget seeing you cutting gears by hand in your earlier videos. This is a great testament to how far you’ve come as a maker and a creator. Keep it up Uri!

[@TheOwlman]

Free hobbing is always a bit iffy - the general recommendation is to gash the blank using a dividing head to get the correct number of spaces and let the hob profile the remaining "teeth", though you can still lose a tooth because the flank of the hob that is driving the blank tends to cut away somewhat more than it should and once it starts, that tooth will steadily vanish.

[@hectorgutierrez5366]

[@andyclaude6227]

Favorite part of the video is seeing your hand out of that cast Uri! So glad you made a speedy recovery and are back to creating so soon!

[@lesterdelacruz5088]

Kinda incredible intuition for engineering something out of the blue. Super fun to watch your skills.

[@sshep7119]

@UriTuchman, Add a small piece of loose felt to the bottom hole of the oiler. The oil should wick down to the bottom slowly. A lightweight hydraulic oil should work perfect on the spindle for what you are doing. The hole that you filled with the custom screw is probably for a split nut to adjust the X axis travel as the nut and lead screw wear together. Look for a spiral flute tap to use as a hobb, the standard 4 flute tap has an excessive amount of interruption in the cut. Support the tap on both ends to prevent the excess vibration above/below the centerline of the part being cut.

[@Vault57]

Uri, 6:09 find the center of a pin that fits the hole. Then, drive the pin out when you are ready to use the hole again.

[@Solarneutrinostar]

I lost it also watching you refurbish the lathe…Gorgeous.

[@ikkiiiieee]

Lathe making with Uri is what got me into lathes

[@mattgeekman]

I've actually seen an oil soaked piece of wool yarn or felt placed in the hole below the cup to prevent the oil from just leaking out when you fill it. It maintains light contact with the shaft and also acts as a cleaning cloth to grab any particles to prevent them from entering the plain bearing.

[@rfdave3980]

[@Jacques.Bodaire]

Uri, you inspire me to try to make my own tools. I'm not good at it, but when they work it's great. Thank you for all you do!

[@hughcoleman3866]

Glad you got it working. Here are a couple of tip 1. Use a Helical Fluted Tap. This will be that there is more tooth of the tap in contact with the blank and the rotation of the blank in relation to the tap will be more positive and reliable. 2. Start with a thicker blank than you actually need. Same reason. You can turn it to finished thickness after the gear cutting.

[@silver3323]

I think that the blank was so thin that there were times that no tap teeth were in contact at all meaning for that period the blank was free to rotate a random amount. I agree that a helical tap or thicker blank would be improvements.

[@engineerauthorpilot]

[@darkshadowsx5949]

if you haven't already try a spiral fluted tap that way there's always some teeth engaged with the soon to be gear. having a gap wider than the material means the gear can slip and you accidentally cut teeth you want off. your craftsmanship is beautiful. if you're going to spend a lot of time making something its worth making it look good.

[@NoTimeForThatNow]

8:47 giving the people what they want! You are the man!

[@12prasad21]

Hi If you pre cut some rough edges (shallow) on the gear blank at correct tooth locations, and run your tapping tool slowly, you will get nearly perfect results. Cheers

[@orion7353]

Hi! In every other year hobbing video I've watched, they physically and verbally say to hand start the gear your making a decent amount. I would recommend doing that, once the tap has bit en enough at one point, it should align with the rest of the material as you're trying to do! 😁 Best of luck to you my guy, love watching you learn with a bit of whimsy!

[@paulcooper2897]

The only thing you need now is a vertical adjustment on the "gear" holder so you can hob full gear instead of radiused teeth. Love the design and build!!!

Idea for the Old lathe could be an "Uri's take on the Turnado" (eccentric engineering makes a terrific piece of kit for "free handing" metal on a Lathe) Basically a workstation for you to make artsy shenanigans in a less inhibited/linear environment. Best of luck!

(if i don't misjudge the idea, which wouldn't be the first) The amount of rigidity required for purposed project could be in the ballpark for said machine.

*Uri Tuchman's videos are a captivating blend of artistry and genius, leaving me inspired and in awe of his craft. Thank you for sharing your incredible talent with the world.* 👍👍👍

[@MisterMarcus79]

The success of such kind of gear hobbing depends on wether there is a continuous cut from the cutter to the workpiece. So the tap wasn't really working at first because of the 4 big flutes relative to the thin workpiece, the actual gearhobbing cutter has many flutes and very small openings so it has almost continues contact with the workpiece from the start. This greatly reduces harmonics but you still need rigidity so no long cutters or large diameters but still...

[@TheUncleRuckus]

I think you should just save the watchmakers lathe for another project. Maybe make yourself a cuckoo clock and you can use your upsidedown bird logo as the cuckoo. That would be a cool build video. 👍👍

[@jimnicholson4509]

I love this guy he is so funny and entertaining, many thanks. Jim from Australia.

[@feynthefallen]

I'm glad you figured out on your own that a tap is NOT a gear cutter. About the watchmaker's lathe, I have a crazy idea for you, that _might_ just work: Use it to make really tiny parts. That's what it was designed for, that's what it can do. And replace that ridiculously big 3-jaw with a nice small collet chuck in the sub-20mm range. Seriously, look at that thing, it's proportions, its belt drive, and figure out the cutting forces it can supply. Those things simply aren't designed to hob huge gears, they are designed to make .6 mm screws. And that's what they do well. Also, well done. It's been gratifying to see you grow from your humble beginnings into a competent engineer and fabricator.

[@thijsrikkerink6333]

I think it would help on the brass lathe to add a tailstock so the cutter is supported on both sides like it was on the other lathe

[@homemadetools]

Great job! We shared this video on our homemade tools forum this week 😎

[@grsymes]

I think the flutes on the large tap were too big for the thickness of the brass blank. This mean the blank lost contact of he tap which is why the blank stopped rotating. Hobbing machines usually work by the cutter and the blank being turned by the same motor. Look up a book called "Wheel and Pinon Cutting In Horology" by J. Malcolm Wild, I think most the old machines they show in the book cut one tooth at a time but you might get some ideas.

[@sidekickbob7227]

Great work, and splendid design! My guess for one of the reasons why it "failed", is the wide gap between the cutting edges on the tap. You want constant connection between a cutting edge and the piece you are working with. As you tried it, there was nothing to keep indexing/rotating the wheel between the time one cutting edgde left the wheel, and a new edge entering. This will easily result in the new cutting edge just making a brand new cut, instead of indexing in the exsisting one. Another tap, or the correct cutter you bought, could help. Also a slower speed could possible help you out for a better result? (Hard to see rmp on video)

I've done something similar, but more primitive, in my lathe, a few years back, and it worked OK. It seems to me that your problem was insufficient contact pressure, particularly when starting the cut. Anyway, it's a beautiful add-on and you can do high speed reduction with only a worm and a gear, if you ever need it - I used mine to build a small size motorized hacksaw.
