First thought: Sounds ALMOST too normal for a Uri video!

It might not be the backplate causing the wobble. When you tighten the nut on the motor shaft it will not be exactly square to threading. This will result in the backplate not pressing evenly against the stop behind it. This is usually fixed by using self centering washers which are essentially two washers with opposing conical faces. These conical faces will slide against each other and compensate for the out of squareness of the nut.

There’s something about adding brass to a build it adds class. It’s like the James Bond of all the materials.Anyway thanks for sharing I always enjoy your content

Less than a minute in and you have already just eyeballed the damned diamond wheel alignment. Among engineer-artisan channels, you are one of a kind, Uri. Never change.

Splendid! Although I think it really needs an engraved pigeon on it somewhere. ✌🏻🎨☕️

אלוף אתה. השראה. לפשטות . לתחכום. להבנה שאנחנו מוגבלים ושהדרך ארוכה. לשמחת היצירה. לשובבות.. להומור. למחשבה צלולה ובהירה. חזק וברוך אורי.

It is such a pleasure to watch a master at work. Your abilities and ideas are unmatched on KZfaq. Thank you Uri for sharing.

That was wonderful, but the drill press sections were pretty scary. Maybe some drill press clamps would be a good idea for a future project, perhaps with some brass.

Uri Tuchman is the Bob Ross of the maker-world. Every episode is full of “oh my gahd I made a little mistake there. And there. And over here too”, but somehow each piece comes out looking amazing. Imagine how it would be oh he didn’t make any happy little accidents.

I love the fact you also show the trail and errors. I´m a tinkerer myself and a lot of time is going into figuring things out.

It is such a pleasure at watching you design and create your works of art. Your silly side is wonderful and your so creative. I’m very happy I ran across your channel I guess almost two years ago. Just love all your creations Uri. 👍👍👍

I love this channel and I appreciate everything you do. I understand and appreciate your processes and all the little quirks that I feel I have in common as an artist and creative myself. I love that you show your real self, the happy creative. I like to think I have a broad knowledge over many areas that allows me to think in a way that nurtures and drives my creativity. But you are on a whole other level. You encourage me to continue learning and teaching myself. Everything you do is so creative and I love the new Pigeon studio soundtrack 😊 it’s awesome. Love to you and your family from New Zealand 🇳🇿❤️

Your videos are always a joy to watch. Your creativity is always inspiring.

Uri your skill and ingenuity never ceases to amaze me. What you do with your limited tools is very creative and inspiring. And I like your good spirits and sense of humour very much. What else can I say? Oh ... just keep your workpiece secured for Gods sake! And save your fingers and other bits! Thanks for sharing, best wishes on all your projects.

I love your enthusiasm ! Great result.

Truly a joy to watch you work

The brass nuts don't work because the lever arm of the tool post can act against the thread. Even using steel bolts will not fix this, I think. Designs similar to this that work use a pivot pin and then clamp the two mating faces together, but have an interlocking pattern on the mating faces so they cannot slip. Perhaps a hinge pin combined with a series of pin holes that set the arm at specific angles?

Fantastic engineering, always a pleasure to watch your videos.

BLOOD!...SCARS! ...My God The Man Suffers for his Art. Excellent as always. Keep on keeping on Uri

You are a very talented and also an extremely funny guy. Your videos are a joy to watch. Keep it up!

Excelente tutorial Uri , como de costumbre , es un placer verte trabajar con las manos , cuidarlas mucho , gracias por compartir tanto ingenió y conocimientos , un saludo cordial y por supuesto un gran like desde Narón (Galicia)🤓 🔝

What a brilliant idea and a great tool

I don't really know why but I found your little video quite entertaining. Thank you for the show good sir!

Uri, this turned out amazing!!! ❤️❤️❤️❤️❤️❤️ But one piece of advice? Breathe! You were on high speed through the whole video!!! You can catch your breathe now!!!

You need to play the theme to jaws as you slowly pan towards the drill press

Great job, I loved the creativity

I've been planning to make a diamond grinding setup on my lathe. I was planning on making a plywood rest, but now you have me thinking I should step it up 🤔 great design

I like the way he is using simple hand tools.

Custom brass knobs had me. Like FFS is he lathing them smooth BY HAND *subscribing

it's nice to see tat you drop things as well as me

Nice Job, Uri!

"Lovely Jubbly". someone has been watching OFAH!

Great idea, well done.

Uri, you need to look into the Harold Hall books for lathe and mill home made gadgets. Then you can embellish them with your characteristics. I think it would be a real benefit to you in your shop.

Ooh Uri Tuchman how I long to see A video upload presented by the thee I know for certain it warms my heart Just watching you go about creating art

Thanks for the video Uri, I'm inspired to turn the left hand end face plate sander on a wood lathe into diamond wheel. I suggest you make or buy vice for your drill press next !

Speed control would be a great addition 👌 👍 👏 🙌 😀. God bless you and your family 👪 🙏 🤲... Lee

Nice work and good ideas.

Bravo Uri

Inspector Clouseau in his hobby shop. Well done mate.

Pure craftsman 👌

Super interesting video, but I have a question. Why didn't you set the support plate higher, i.e. above the axis? Then you would have the entire width of the grinding plate available, and it would certainly be less dangerous for your fingers

Always a pleasure.

I have the same set up in my shop. I have 3 registration pins and have the disc mounted on a plate with magnets. Can go from course to very fine in seconds.

Great to see the new video, some stop blocks for the drill press might make drilling have less blood being loss to drill stuff.... Be safe and hope to see more videos this year...

Love the build of the table and miter fence! You are a maestro at this kind of build!! 2 issues: first, use conical or cup and seat washers for the back plate and lapping disc as @Dan Letkeman says below. Once that is done you could use your miter fence to true the running face and edges of the back plate with sand paper and a square block. Second, most grinders run at 1750rpm which is way too fast for lapping disc and will wear them out quickly. If you can find an inline speed controller for the grinder to get the speed down to around 800-1000 it will help a lot. Typical lapping plate systems actually spin around 4-500rpm. Thanks for the fun build!!

Oh..my.. this is better than perving. I'm excited.

Yuri one thing when you are cutting with the saw CUT in the right side not in the left side because you can shock you hands at the table. In the right side tour hand go to the Air and can not shock your knockles good video yuri

Success of a project is directly proportionate to the number of "oh my god" moments you have in making it. For good, bad, or scary.

Hi Uri, I assume you've already checked the axle for runout. It's a pretty common issue with these small bench grinders.

I made a similar thing to you with a mount that took every grade of diamond disks for marble top finishing. Mine was for polishing and cutting Opals, I also made a water feed gravity fed with a tap.

There is a word in italian that describe you very well: pasticcione. I can't find the translation cause the meaning is not so negative as the english words, but even if you are a pasticcione, you are always dead precise, i can't understand how you manage to build perfectly functioning tools like this🤣 is always a pleasure to watch your videos

As always a very delicious video you've made 👌

Always a Pleasure 👍🏻

Using a chasing hammer to pound a center punch is the definition of Uri Tuchman (not because it was wrong or bad, but because he can make that work =)

Now yes, friday! 🙌🏽👌🏽

Very nice! But it almost seems too conventional for a Uri Tuchman project! Why isn't it shaped like a pigeon or pork chop or something? 😄

nice work

Nicely done Uri... an enjoyable watch, than you

Very inspiring!

Pleeease invest in (or make) some clamps for your drill press. I could hear the echoes of my industrial art teacher scolding me every time you used it lol. Great video as always though, of course

this second zoom at 3:16 cracked me up as you were playing somehow with my expectation that it will spin again :D damn i love this editing

Uri just going in with the fat chips definitely got me all puckered up

Bravo! Also, you need a drill press hold down clamp.

I'm glad to see you have a Taig lathe, they are flexible little machines that really lend themselves to shop made modifications too. Looking forward to seeing your projects progressing!

Gotta be able to sharpen that carbide... Well done Uri. The wobble could also be in the washers, the shaft itself, or play in the grinder motor. Most bench grinders have some sort of play/run out. The more expensive ones have less. There are beveled washers you can buy for the mounting shaft then you his have to play with a pair of washers to get that perfect adjustment to true your grinding wheel, or in your case diamond plate. Bench grinders aren't really designed for face plates, but for edge wheels. But a true running shaft is a true running shaft. Good luck.

Good video!

good progress... accuracy is a journey and not a destination... =D

Uri great tool, hope you can fix the squareness issue. Also hearing you say lovely jubbly made me chuckle.

Small projects like these are my favorites. If you get them right the first time it's so satisfying but if you need to remake them because they are to small or to big the "how to make" process and the "don't do thats" has already been done so all you have to do is scale up or down. I have to admit I have copied some of the things Uri has made. 🤫🤫 love this channel.

Years after hanging out at truffle pig, I’m still here every week. God this is fun content!

Melamine works quite well as a backing disk. It is surprisingly flat. In fact I've seen quite a few people successfully lap parts using diamond paste on a bare melamine wheel! Seems to work just fine although I would be concerned about moisture. I tend to dip parts in water rather often while grinding

There he goes again: the god of brass!

Uri, Check the shoulder on the bench grinder, sometimes they are not nicely machined. The slightest of burrs will throw that 7 or 8 inch diameter out quite a lot at full diameter. Your original backing plate may still be fine to use. Use a fine flat hand file and use the NON safe edge against the grinder spindle shoulder, rotate it by HAND to check for burrs. You may also find that the shoulder has a radius, so your backing disc will need a slight bevel to the hole to miss the radius. Good Luck fixing it. Regards from Australia.

Keep the table closer to the disc to stop anything being dragged down into the gap…nice work…👍

Neat! Don't worry about the guard..diamond doesn't cut & the wheels unlikely to explode!! Re the flat lap..the grinder flanges might need truing to the grinder spindle (standard grinders aren't precision kit)!

to even the back plate i would put three spots of cusi with a tig welder and file them until the weel runs centered. you can also drill a larger hole into the disc and make a bronze bushing spacer and try to make the bushing more precise. if the disc is not flat you can sand that to be flat on a flat surface.

Благодарю! Все сделано отлично! Однако, прийдется доработать нижнее крепление, чтобы исключить проскальзывание между подвижной и неподвижной частями, осевого зажима недостаточно. Обычно, для таких целей, используют такую-же конструкцию как Вы использовали для установки горизонтальных углов заточки. Есть и другие варианты но они потребуют больше деталей, и в конечном итоге затруднят настройки вертикальных углов из-за люфтов в соединениях. Успехов Вам!

Unnecessarily exquisite and oddly satisfying as ususal.

Hey Uri, haven't you thought about doing a mechanical clock? You have the knowledge, as well as the tools! I'm pretty sure that it would look pretty great.

You're slinging some chips now buddy. Lol. I really enjoy watching you make stuff. The comedy is a plus lol. Hope you're doing well buddy. I bet you miss your cats walking around what you're working on lol.

There are special washers that take the wobble out, they are spherical, I believe? They come in sets of two and nest together and compensate for things being off.

You are amazing!

hey Uri try a plastic backplate to suport the diamond disk, because you can true it up using a bit on the machine itself then glueing the disk

If you put some sort of friction discs between the sections of the support arm, the screw won't need to be as tight to get it to stay in position, so you may be able to use your thumbscrews.

Very very nice

Supercut of just every time Uri says "Oh my god"

What you need is some clamps lmao. Protects the fingers

Impresive

Diamond at high speeds deposits carbon into the sharpened piece. This is mostly experienced in industry but I’ve heard of guys power grinding their knives with diamonds and it ruining them. The ideal abrasive material would be CBN or Cubic Boron Nitride, but if it’s any harder to get than diamonds then I wouldn’t worry. Keeping things cool and or lubricated can cut down on that quite a bit. You’re a natural toolmaker Edit: I thunk you’d have fun with a 0.5-40 micron diamond paste pack. I got one from venev for like $12 and it makes polishing hard materials a breeze.

You are good!

Agree it can improve

Put a piece of copy paper between metal surfaces to give much better grip and locking. Greetings from Tasmania Australia.😁🇦🇺🦘

I love your commentary when you let something fall etc. 😅

Love me some you, bird man!!!

I kind of lost touch after your son was born and you kind of took a break from video making. Good to see you back. Seemingly a nice shop too. I think the last video I had seen was the live stream with your wife's friend acting as more or less host that then ended with the camera seemingly going mad on its own. I like your mini lathe. I have a Shopsmith wood lathe that I enjoy using and an old Oliver small metal lathe from around 1900 that needs converted to V Belt and they certainly are enjoyable to utilize and it shall be interesting to see what you output with yours.

Very impressive. Great video. Question: Is the sharpener spinning to fast to sharpen your tools? I always thought they were much slower.

Excellent build friend, I'm sure there are things to update. A real backplate will do wonders for true flatness, no wobble. I would not add a safety guard ... will only get in the way. but always try and hold small spinning parts with a vice grip if possible... too many safety nazis. I'm sure you have things under control. Also, I noticed you have the other end of the motor shaft idle, not in use. I rebuilt a Grinder and replaced one side with a (Motor Adapter Arbor 1/2-20 Threads Fits 1/2" Motor Shaft or Spindle) Look on eBay..$24 bucks. Make sure you get the correct right or left threading for this. Then I added a Drill chuck!!! Now I can use all sorts of adaptors for diamond, Wire brushes, and even 4.5 Hand grinding disks. And I can place a drill bit in it or even sharpen one. Works so well You should try it. In the US the Adapter Arbor is about $24 a chuck around 12-$14. The chuck may not be perfectly centered, but even then if you leave the grinder motor on its rubber legs this will compensate and center the chuck very well... I use this little junk motor all the time now. It is small enough I can stop the chuck by hand but it still has some power. In a shop like yours bench jewelry style, I can see this would come in very very handy. You won't regret the chuck adaptor. Sir.

Perhaps you should make a vice for your drill press.

Beautiful work! And a pleasure to watch. Thank you 🥰
