HOBBING ...HOBBING ....HOBBING ... what is it good for? absolutely everything! Hobb on over and let's get cutting! Patreon: / urituchman Instagram: / urituchman Music: www.epidemicsound.com/
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 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.
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.
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.
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.
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.
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.
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.
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.
@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’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.
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 😎😎😎
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
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. 👍
Your videos are inspirational, I love how you create a mix of the mechanical with the aesthetic and what you have at the end is both beautiful and useful. Thank you for sharing your work.
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
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.
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
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.
*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.* 👍👍👍
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'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!
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.
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
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.
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.
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!
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😀
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.
So good to see real life workshop, Uri. I watch quite a few makers on RU-vid and comparing their workshops to mine I feel like I'm doing something wrong :) Mine is always dirty with engine fluids, metal shavings, wood chips and all that, just impossible to keep it in proper "studio" condition.
good work mate, glad people are branching out into gears. i bloody love them haha. if you want to make spur gears you will have to somehow make either the tap move up and down or the job. you will also have to figure out a way to cut a specific number of teeth that you want by say a gear train or something. Andys machines has a good encoder one that does it all itself.
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
