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.
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.
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.
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.
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.
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.
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.
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.
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.
Man Uri, I don't think you understand how smart and capable you are, great job!! Always a pleasure watching you work and be yourself. You're a big inspiration. Thank you for sharing and for brightening my day
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!
Haha you did it! You did the thing! Thanks Uri for being one of my absolute favorite artists on youtube. I love your approach to crafting and the attitude you have while doing it. I thoroughly believe if you lived in Da Vincis time he would collab with you on his projects.
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.
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.
URI, The world would be a sad place with out you my friend, your an inspiration too all us mad people who like too make, because we just like too make stuff. THANK YOU 😎😎😎
@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.
I'am very happy to have found this clip! I have also one of this machine (pretty much the same type), that i have got from my "late" grand dad! Was told by my father that my grand dad hade made it him self, but I see now that it must have been a "kit" he build it from. I like the work you done to it, and a great video clip!, Thanks a lot!
Mr. Uri , I enjoy watching your video. The level of craftsmanship is incredible. I watch and try to imagine how the pieces will fit together. Thank You
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.
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.
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.
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.
I find old tools like this just as valuable for how they look on a shelf for display. Glad to see you getting it back to work after a lengthy retirement. 👍
Mark Twain once sat in front of an audience and said nothing and made them laugh by his very appearance. Uri is this same kind of man. Everything he does makes you laugh. And while hes making you laugh, hes creating wonders of the world. Such an amazing talent. I wish there were more people like him.
Uri, you are such a beautiful person. I watch so many creators on youtube and i love many of them - the ones I gravitate towards are inspiring, talented, and creative. You are these things and more. Your willingness to push your capabilities and show your mistakes is so so inspiring. Since I've started watching you, your mindset has bled into mine. The whole, "Can I actually pull this off? I don't know, but let's try" attitude is so valuable to a guy like me. It's so COOL. Thank you for creating and sharing with us.
Beautiful engineering mindset you have .The way in which your work place itself speaks volumes of your skills. No words to speak about your metal working in the lathe. Kudos.
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!
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.
So happy that I stumbled upon your channel. The woodworking and metal working that you do offers a lot of inspiration to new people who also enjoy both crafts
Dear Uri, a wee trick that I learned from Joe Pieczynski when parting off is to hold a small screwdriver up the bore of the item (if it has a bore) so that the item when parted stays on the driver rather than disappear into a pile of swarf
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
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!!! I've been thinking about an improvement to my Taig ... and I love that handle you made for the watchmakes lathe! I may have to borrow that shape. Thanks for sharing 🇨🇦
Absolutely loving the longer video with detailed content. Very nice. Never seen this type of machine before either. Would be good to make a cookoo clock from your fine wood and metal skills. Keep up the great work.
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.* 👍👍👍

Uri, I've been watching your magic for years by now, and you're never boring😀👍 If I could have one wish, I would love to hear your story, why and how you got into this work😀
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...
I freakin love your channel and everything you do my friend. I like that you show everything, the good and the almost fails. Thats how things work. You're really talented, funny, and creative, that's what makes your channel one of my all time favorites. The best part is when you made the music pick back up when it started to work, lol. Now you will never have to hand cut and file your own gears ⚙️. Very cool. Great job bud, i cant wait to see whats next. Stay safe and god bless you
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.

Thank you Mr. Tuchman, you are greatly appreciated by so many.
Thank you Scott! That means a lot!
You forgot to mention that he is an outstanding engineer. I have the greatest admiration for the skills he has....and his workshop.
Yes you bring it of the Point!🤘🤘🤘
@@urituchmanpigeon How you know his name is Scott? Does he work for you?, How much he pay you to got payed? so many questions...
@@Wasko1312Jeffrey kalf it says on yours
The world needs this man to collaborate with Clickspring on something.
Uri would receive an education.
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.
@@Mr7yhnmki8 Taking nothing away from Uri, I have to agree. Mind you, Uri could bring equal value to click spring.
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.
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.
It was a hobb-it.
Finally, a proper time transition!
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.

Kinda incredible intuition for engineering something out of the blue. Super fun to watch your skills.
It's the scope of his workplace tool collection I find endlessly amazing.
You definitely need a tailstock with supporting center on your new lathe, so it will cut gears I think likeTaig. Nice to see this new work Uri!
URI,
The world would be a sad place with out you my friend, your an inspiration too all us mad people who like too make, because we just like too make stuff.

Lathe making with Uri is what got me into lathes
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.
Seeing you work is giving me incentive to get back into machining when I move off my boat and get back to a house on shore. Nice work you do.
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.
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.
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!
