Angle dresser for the surface grinder

[@ROBRENZ]

Very nicely done Stefan! I agree, stock rack engineering on the fly is one of my favorite activities. Still waiting for the dc motor dress speed controller upgrade ;-) ATB, Robin

[@StefanGotteswinter]

Thanks Robin! I dont even dare to ask, but what do you use for angle (and radius) dressing?

[@StefanGotteswinter]

I saw your overhead dresser on the EEV Blog forum, that thing is very nice.

[@ROBRENZ]

I dont do a lot of radius and angle dressing but I have a J&S fluidmotion dresser www.jstool.com/wheel.htm when I need it.

[@ROBRENZ]

I dont remember where that was on the EEV Blog forum but There is a good instagram pic here instagram.com/p/BXTX35-gGVl/?hl=en&taken-by=robinrenzetti The micrometer head you can see is for the angle adjustment. If you look real carefully you will see the flexural hinge on the left and the stabilizing flexure on the right for the angle adjust. There is another micrometer head not visible on the left that downfeeds the diamond arm. The dress traverse is air cylinder powered (not visible). The big white thing is a calibrated dial in inches per minute that I made to go on a Dershner Kinecheck hydraulic feed control ( the shiny cylinder with the blue label. I calibrated the speed with a linear potentiometer set up as a voltage divider fed into a digital scope where I could calibrate the delta time over delta voltage.

[@StefanGotteswinter]

Thank you for the explanation. A over-wheel dresser is absolutely on my list, I looked at a few designs, some had hinge-pins or Pointed setscrews as a hinge for adjustment, but a flexture seems to be the better solution. For now I have to resolute to my calibrated arm for constant feed, but powerfeed for the dresser would be a very nice thing, indeed.

[@TomZelickman]

I love how you just create this type of thing in your spare time without drawings. As always, that's really nice work. Great idea! Sincerely, Tom Z

[@douglashank8480]

4 hours. No plans. *SIGH* I'd feel like I was doing pretty good to build that in a week. I have far to go and much to learn. Thank you sir, for another excellent and inspiring video. 😊

[@kglesq1]

Brilliant as usual. I always enjoy your videos Stefan, thank you for sharing them.

[@forrestaddy9644]

Dust capture on a grinder is always a PITA. I HATE abrasive dust, especially around machine tools. My approach yesteryear was to tightly shroud the dust source so the incoming air at the clearance had sufficient velocity to carry the fines. The whole grains might escape but they are far easier to vacuum up. I suggest a hunk of plastic pipe sculpted to fit the wheel width with 5mm clearance with the lower proportion heated and fitted to catch as much of the dust stream possible. I have a dedicated 1200 watt vacuum I use for abrasive dust and precision scraping. I never use it for general clean-up because I don't want the filter clogged. I built a similar gadget with a tiny mounted diamond lap I used on the planer table for touching up carbide broad nose tools. This gave me the edge parallelism I needed for generating smooth flat surfaces on cast iron tables and way surfaces. Done right the finish looks like gray satin ribbons layed parallel edge to edge. Can a fitted felt wiper be installed as a first defense on the linear gearing cartridge? Nice piece of hurry-up work. And yes it is fun to go direct from concept to finished product. The intervening paper design step might produce a more elegant solution but it leads to endless cycles of trivial improvements often losing the original purpose in the process. All you needed was an egg timer but somehow the project evolved into a ceasium clock.

[@pedrocavaleiro3688]

That is a beautiful tool! What's next? A plexiglass cover that fits on you machine's existing fixtures, slithed underneath so your diamond cutter may travel side to side, and wich directly connects to your shop vac to eliminate all dust from dressing your wheels? That's nice! Yes, I know I'm overreaching, but had to try it anyway :) Love your videos, thanks for sharing!

[@erlingweiseth2774]

Very nice tool! The ToolMaster strikes again! Thanks for always inspiring and entertaining us all!

[@mtm101designs9]

Impressive work. Having recently purchased my first surface grinder I am excited to work my way towards your level of skill. It is always nice to have your level of craftmanship as a goal.

[@dennyskerb4992]

4 hours? That would've taken me four days! Nice job Stefan.

[@ChiralSymmetry]

Nice! Thanks for the video. Slightly curious about the linear slide. Does it have a way to reduce play and/or backlash? Maybe a pre-load adjustment for the linear slide bearings?

[@charlieromeo7663]

That's one nice tool Stefan. You really do nice work. Thanks for sharing.

[@raymondmarteene7047]

Hi Stefan, Very nice piece of tooling, when I first saw it I thought you had built a retractable tool holder for single point threading like the one described in GH Thomas’ book, lots to learn from this project about function and simple design. Thanks for sharing. Cheers

[@outsidescrewball]

Awesome "quick" build...thanks for sharing

[@TheJoyofPrecision]

Well done! This is the first time I have heard a German talk about a Belleville washer. ;-)

[@dizzolve]

Awesome gadget. Maybe a locking bolt would be useful too

[@lorenlieder9789]

Great job on the angle dresser Stefan!!!

[@wallacesaan]

I am new to surface grinding .... In my reading so far I understood that the diamond should be mounted at a 30 degree angle (away from rotation direction) so that you can rotate the diamond before each use and add to its life. Is this not really necessary? Thanks for you super helpful videos. I have learned a lot from them.

[@lionpauu7360]

Great video and superb workmanship as usual, many thanks. The stone roughing can be done with the diamond slightly beyond the centreline as usual, but the finish cut must be done on the on centreline or the lowest point or the ultimate accuracy will be lost, a small point but worth highlighting.

[@sharkrivermachine]

Very nice build!

[@pgs8597]

Beautiful work as always. That wheel definitely needed dressing, no matter what angle. The problem with dressing any wheel is it needs to stay at that angle or near, otherwise its diameter quickly diminishes. Thanks for the video, Peter

[@EmmaRitson]

thats a bit nice.. Im sceptical about the "couple hrs" claim, but otherwise, well thought out. are the screws plated or stainless? you are an inspiration to stop messing with junky 3 d printers and make nice things stefan.

[@manickn6819]

Yeah I was wondering about the time too. Looked like a lot of work. Good finish. Good job.

[@carneeki]

No drawings? *Unsubscribe* Lol Very nice work :)

[@bcbloc02]

maybe someday I will have a grinder to play with to do these sorts of fancy things on. Mine is only really adept at flat work.

[@captcarlos]

I'm sure supervisor Baily could help.

[@MakinSumthinFromNuthin]

Thats a tool to be proud of....nice job Stefan 😊 ~ Richard

[@StefanGotteswinter]

Thank you Richard!

[@MrShobar]

Ausgezeichnete Arbeit, mein Freund.

[@cnc-ua]

Great looking tool, man I wonder if it can be improved to get better sand protection

[@routercnc9517]

Another great little project thanks for sharing. Maybe add a light return spring to pull it away from you on each stroke ?

[@StefanGotteswinter]

Hmmm, not sure about the spring. I removed the spring from my toolgrinder, as I dont like when stuff moves by itself back..

[@routercnc9517]

OK, no worries. Keep up the great work !

[@TomChame]

Beautiful job!! Shouldn't there be an adjustment for tidal shift and moon phase?

[@StefanGotteswinter]

No, that goes to far. But coriolis force is a real concern.

[@TomChame]

Stefan Gotteswinter I have no doubt you can do it.

[@393strokedcoupe]

Stefan Gotteswinter No problem, just get together with Adam (Abom79) Booth and figure out what to build to slow down the Earth's rotation. You may wanna give Tom a call too @ OXTOOL. 😉 Anyway, awesome as always!👍

[@somebodyelse6673]

Ah, that will be for the accessory with helical dovetails to attach an Antikythra mechanism...

[@Ed_Stoddard]

Luckily I managed to get a 12" radius dresser with a lot of tools I bought. If only I had a grinder.. lol Great vid and good use of what you have on hand. My kind of project... Cheap..

[@peteferguson7024]

Nice little, on the fly, shop made dresser. LOL --- Abrasive rain, the lesser known, little brother of Acid rain :) Thanks for sharing

[@chuirios365]

Had you mounted the slide on the opposite side of the angle plate, the wheel dust wouldn't be such a faster. However, I really enjoyed the video. Outsidescrewball, (Chuck) and I did a video on a quick, and dirty setup angle dressing. Thank you.

[@SolidRockMachineShopInc]

Hi Stefan, Nice project. I made an attachment to use on my 5" sine plate to dress angles. I still have not come up with a good solution to protect it from grinding grit. Steve

[@StefanGotteswinter]

Thank you! Dust protection is realy an issue - I have some thin leather here that I will make into something like an apron going around the diamond, covering all the moving parts.

[@raidoenn8141]

Hi! Nice build, I think you should add a leather cover with holes for the diamond and handle to pop through. And a magnetic rail on the end, much like the lathe. Keep it up!

[@StefanGotteswinter]

Black leather is already ordered ;)

[@atowning]

Nice one Stefan, i usually fing the spontainous unplaned biulds are the best :)

[@madinatore]

with an acurate perpendicular base of the tool, wouldn't a 30° angle set be translated to 60° with a 90° rotation allowing even steep angles acurately being set? (setting the angle with the tool upside down I mean)

[@StefanGotteswinter]

Yes! And thats the reason why I surface ground the "angle plate" relatively precise square :)

[@raidoenn8141]

But is grinding angles steeper than 60 deg really a good idea. I think the wheel will start to lose much of its structural integrity and fail quite catastrophically with your fingers right next to it. No?

[@StefanGotteswinter]

You can dress a wheel to be about five times the grit-size thickness without having major problems.

[@ApukEldar]

Awesome! Bravo Stefan.

[@risfutile]

"Scavenged from my semiconductor production, as you do"... xD But could you maybe tell a little more about the prey? That sounded very intriguing!

[@jeffryblackmon4846]

Well designed and carried out. It looks store bought.

[@billsmith5166]

Brilliant. How much would you charge for a signed poster for my shop?

[@zumbazumba1]

Silica carbide is in the air ,everywhere i look around ! Silica carbide is in the air ,and it has hit me in the eye and i know that i have been foolish for not wearing a mask. Every similarity with love is in the air song is purely coincidental and unintentional,do feel free to continue thou ! Stefan where did you get the dressing diamond ???

[@StefanGotteswinter]

Haha, the dressing song, OSHA approved. The diamond is from ebay, I think that one was vertex branded.

[@VinceSaluto1]

Very nice Stefan. Thanks for sharing. Everything you build I want one. I just don't seem to have time with my own projects. I do need one of those.

[@VinceSaluto1]

Just not sure where to get that bearing.

[@tridium-go6hw]

Try searching on eBay for "linear sliding rail block" and variations of same.

[@VinceSaluto1]

Thanks tridium6111 for the info.

[@BickDE]

Very nice Stefan.

[@StefanGotteswinter]

Thanks!

[@68sweetnovember]

Excellent

[@watahyahknow]

think you can set the higher angles by tilting the whole thing on its back , set it and put it upright again

[@dizzolve]

is that dust collection an aftermarket product? I need to find something a bit more effective than my current set up.

[@Teunbaartman1]

great as usual!! any tips for purchasing a linear guide with such small dimensions? cheers Teun

Danke schön!!!

[@StefanGotteswinter]

What Frank said ;)

[@RRINTHESHOP]

Love it, very nice.

[@robertkutz]

stefan nice work.

[@11thboris]

Does your diamond tip need to be exactly under the axis of the wheel, in order for angle to be exact?

[@StefanGotteswinter]

Eye-ball precise. I like it to be just a bit behind the centerline, in case of a crash its not as catastrophic as if the dresser was in front of the centerline...then it would get sucked under the wheel and the wheel would pretty sure explode...

[@11thboris]

i am not familiar with wheel dressings, was just thinking bout the geometry and the effect of position of that diamond tip to axis of rotation, the further away it is from center the less precise the angle it self is; was my thought process. thanks for the video as always. I see Stefan video in feed i click.

[@StefanGotteswinter]

Youre absolutely right about the precision issue - But as long as it is "quite" on center, its for most work good enough :)

[@11thboris]

Yea, I think it would be chasing microns, good enough is something we have to live with.

[@lewisl5985]

nice simple design i like it

[@tyhuffman5447]

Thank you Stefan

[@63256325N]

Nice tool for sure! thanks for the video.

[@frankmuller5649]

Hey ... wait... do you realize you just made a TOOL? ;) Nice job... efficient design and the diamond being the only thing actually needed to be exposed... those plastic bags save you a lot of trouble. Thanks for sharing... now small linear bearings will be on a constant high on ebay for month ;) Take care!

[@StefanGotteswinter]

Haha ;) I think I also destroyed the price for small shapers, pantograph machines and small heat treating ovens..

[@banditvinnu9603]

Superb awesom idee

[@StefanGotteswinter]

Thanks!

[@mikeysgarage3697]

Cool little tool.

[@tomvitagliano250]

Hi Stephen...I recently acquired a So. Bend 7 inch shaper. I need a vice and was wondering what brand vice you are using on your shaper. My specifics needs are that it has as low a profile as possible, has a rotating base, and opens to no less than 6 inches. How heavy is your vice ? A response would be greatly appreciated. If possible include you email address.Many thanks.

[@lanphomhair1487]

How I can buy it please ?

[@TechTomVideo]

geiles Gerät!

[@petert6103]

Hobby machinists are like 😕 ....no way I could build that.....

[@CapeCodCNC]

Nice! When will it be on sale! I want one.

[@davindersingh3549]

Good job 🙏🙏🙏🙏

[@derwissenskiosk8041]

How do you engrave the name on your parts Stefan ?

[@StefanGotteswinter]

Deckel G1L Engraver ;) gtwr.de/shop/pro_g1l/index.html

[@derwissenskiosk8041]

I know that your have a Deckel pantograph but do you use blocks with slots in form of the characters ? Or do you use just a pice of papper with the name on it that you follow by hand ? And how do you get this nice black finsh inside the milled slots ?

[@mohdazayhtrgdewam9485]

Radius formulas machine

[@chrisnixon2179]

Can you do a video on case hardening

[@StefanGotteswinter]

AVE just did one ;) I might do a video on heat treating in general at one point.

[@chrisnixon2179]

Stefan Gotteswinter saw the AVE video but the steal was not red hot when he dipped it... then he said it doesnt work... would like a second opinion from some one with more precision. Thanks love your vids

[@eliduttman315]

He's wrong. When done correctly, case hardening does work. Your point about the steel not being hot enough is spot on. "Cherry Red" is 1 of the carbonizing products a DIYer can use. The name tells the tale. Repeated heats and dips, followed by a final heat tested with a magnet and then rapidly quenched in cold water gets the job done. Eli D.

[@intjonmiller]

Great design, build, and video. No need to film the process of making it when it's rather straightforward, so you don't have to spend so long making all of your videos long format, we don't have to spend as long to see it as it would be if it was long format (and I do like long format project videos when appropriate for the project), and the function and design are still completely clear. Thanks! By the way, I have half a dozen or more Carborundum Company wheels that look just like that one. Same age of the blotter style, same color (dirty), etc. It's always interesting to see uncommon items in common in videos of other people's shops.
