    hi i did the same thing on my 1800rpm baldor with a lathe bit. to get a quick and dirty lower rpm i toggled the on off switch every 5s or so. it was good enough to get rid of chatter.

  2. Jeff Anderson on February 17, 2022 at 10:36 pm

    Great video. I need to do the same thing. My mounting nuts run true, unlike Kieth’s. I would be concerned about parallelism with the bearing face. You trimmed off the clamped parallel. If not perfect, you are cutting a taper.
    I have no problem facing the aluminum hub but I have to verify 90 degrees to the z.

    excellent post, thank you !

  4. bill chiasson on February 17, 2022 at 10:39 pm

    Great video!

  5. Duane D on February 17, 2022 at 10:40 pm

    What happened on the model J Johnson bandsaw rebuild? I would love to see an update. Thanks

  6. Don Potter on February 17, 2022 at 10:43 pm

    Where did you get the wheels ??

  7. Stuart Hardy on February 17, 2022 at 10:45 pm

    Stan if your lathe is big enough take the motor off the stand but leave it assembled and the hubs still on and run it between centres then you have control over the speed ,did the same when I made my grinding spindle for my quorn

  8. terry cannon on February 17, 2022 at 10:47 pm

    Great subject Stan. Thanks for taking the time.

  9. Brian Walk on February 17, 2022 at 10:48 pm

    Great video, Stan! Lots of creativity and ideas outside the box! I love the little vice, nice touch with the burnished finish, very attractive little tool!

  10. Chimera on February 17, 2022 at 10:49 pm

    Oh yeah, meat for a hacker. Did that on my HF Baldor clone, but with cemented carbide triangle. Worked, can’t remember excessive chatter.

  11. Fred Miller on February 17, 2022 at 10:52 pm

    Nicely done Stan.  I gotta admit the "clench" factor was pretty high just before you started cutting.  Like a Bulls butt during fly season….  LOL

    your shit is too pretty

  13. somebody else on February 17, 2022 at 10:57 pm

    What are you figuring for wheel life, grinding steel with diamond? Better yet, let us know what the actual wheel life is, when it wears out!

  14. Molb0rg on February 17, 2022 at 10:57 pm

    infeed is super ))

    turn wright machine works did a vid on this very thing and he found some really extreme run out on the nuts them selves once corrected made vast improvements. so check out keiths work.

  17. wayne p on February 17, 2022 at 11:00 pm

    did you get rid of the vibration with the machine running.. you may need to figure out a way to shift the wheels around to zero their run out since they don’t have a hub to pilot on. checking the outside runout and with the screws slightly loose bumping the wheels slightly might remove it totally without needing to remove the wheels from the backing plates. either that or build new backing plates on a lathe with a tighter bore and a hub to center the wheels … but also make a spindle or pilot of that size so you can balance it on the surface grinder balancing jig.. i would probably also use a tiny curved diamond file to take off the high spot you found on the shaft spacer, if its only one spot.. the only other way you might create a balance device is like the steel shot in the ring that mounts behind the wheels on cars and trucks.. each time the car reaches speed the steel shot evens out the balance.. could that be done in your new backing plates? this does not get rid of runout.but it will take care of out of balance issues.. https://youtu.be/ullnFQD4F1I its only a thought.. thanks for the video.. and area the hold down screws and washers all equal weight… that could be an easy way to change the balance.. change the washer weight.. or grind a little off one of the washers and move it around one position at a time. so you don’t loose the work done zeroing the run out. .

    Nice video, very informative and creative.  Thanks for sharing this with us.   Dan

  19. James Hillman on February 17, 2022 at 11:03 pm

    great show. tnx for ideas. my fingers would have automatically flinched…..singing.

  20. Jerry Coleman on February 17, 2022 at 11:04 pm

    Enjoyed your video, hope you are having a good day.!.!.!.

  21. Jim Liechty on February 17, 2022 at 11:05 pm

    Great video Stan. I run a few on my old Delta carbide grinder, and really like it. I have a bff with an extension cord and a magnetic control box, and just plug in my different yes and belt sanders, and great to regulate the speed for different applications. I would look at truing up the but the next time you remove the back plate.

  22. 1970chevelle396 on February 17, 2022 at 11:05 pm

    I have a Blador 510 grinder just like that. I haven’t got to use it much yet. The Diamond wheel I have on one side looks completely different.

  23. Stefan Gotteswinter on February 17, 2022 at 11:05 pm

    And there go the headphone users, haha 😀
    Good solution, came out great!

  24. John Dough on February 17, 2022 at 11:06 pm

    How much for that little vise?

  25. Barry Gerbracht on February 17, 2022 at 11:07 pm

    That would be a pucker moment when first feeding the cutter in. I would probably have mounted the tool upside down in the vice so it was sitting on the table for fear of the tool grabbing and tipping into the wheel (rapid aggressive increase in cutting depth followed by crushed fingers and much foul language). Great job. Love the mini vice with the engine turned finish.

  26. George H. Reed Jr. on February 17, 2022 at 11:07 pm

    How do you use a VFD on a single phase motor ?

  27. Ed KE6BNL on February 17, 2022 at 11:09 pm

    That was a good repair.

  28. Makin Sumthin From Nuthin on February 17, 2022 at 11:10 pm

    That was really useful Stan, much appreciated. I have a knockoff Baldor and between this video and K.Fenner’s vid on this same subject I know what to look for. I have 2 silicon wheels on mine and even without it being bolted down I can stand a nickel on top of the motor and turn it on and off and it doesnt budge which is a good sign but have yet to do a thorough investigation of the machine so appreciate your vid. Btw, where can I pick up a suitable wheel for use on HSS as I dont need two silicon carbide wheels. TIA~ Richard

  29. engineerd3d on February 17, 2022 at 11:11 pm

    Love it Stan. Your a wealth of information.

  30. Rolando Escobar on February 17, 2022 at 11:11 pm

    Great effort and reward! Thanks amigo.

  31. Glenn Felpel on February 17, 2022 at 11:12 pm

    Very nicely done Stan. Would you mind saying where to find the diamond grinding wheels I have the same grinder. Sure do appreciate you sharing your experience.

  32. Michael Collins on February 17, 2022 at 11:13 pm

    Hi STAN we balanced the backing plate and stone together on a shop made balancer with air bearings, worked like a champ. Would be a fun project for the channel! Mike collins

  33. John Valle on February 17, 2022 at 11:13 pm

    So the shaft or bore of the flange was warped. Now you need to index it and never swap sides.

  34. sergio roa on February 17, 2022 at 11:14 pm

    Stan I have the same motor and is missing one of the underneath the table protractor did you have any idea we’re I can get it and we’re did you get those wheels and how much thank you

  35. Santo Pezzotti on February 17, 2022 at 11:17 pm

    Hi Stan I just got that grinder at an auction today. It’s the Baldor 522. Can you tell me what the best wheels fir grinding HSS lathe tool bits.

  36. highpwr on February 17, 2022 at 11:17 pm

    Nicely done Stan. I’m surprised to see that is a problem on the Baldor grinders as well. I have one of the clones that was far worse than that and ended up having to make all new spacer sleeves and hubs that actually fit the motor shafts without the huge gaps. I found the original cast aluminum hubs to be full of internal voids after initially trying to true them up on my lathe. I turned new hubs from some 6061 round stock and new sleeves from some heavy wall DOM tubing. Night and day difference now that those parts don’t shift around on the shafts due to the oversize ID’s that the original parts had.

    By the way, thanks for showing another great way for me to use my awesome Z-squares. I love it!

  37. Railfan 439 on February 17, 2022 at 11:18 pm

    Stan, you machined the faces of the hubs, but did you machine the edges? I thought I saw some non-concentric movement. See you at the Bar-Z. Jon

  38. The Flat Garage on February 17, 2022 at 11:22 pm

    That’s a major modification. Guessing ppl gonna go buy the Taiwan made grinder that Keith Fenner has and modified.

  39. Jeff Erdman on February 17, 2022 at 11:22 pm

    Nice video. Would have not thought of trueing it up on the machine.
    Nice job!

  40. RutherfordRyan1 on February 17, 2022 at 11:23 pm

    Stan, great video. Could the shaft be distorting under thread torsion ? How straight was is it outside the inner bush that indicated true ?
    We used to machine VW drums with the wheel nuts tightened up to eliminate distortion there.
    Best of luck with the Bash.

  41. Hippox Works on February 17, 2022 at 11:23 pm

    Nice toolpaths Stan, even cooler dials.. one tap was 0.001 so infeed was couple thou😄😄

  42. outsidescrewball on February 17, 2022 at 11:24 pm

    nice tuneup and video….

  43. 682 70 on February 17, 2022 at 11:26 pm

    Stan, that was badass. Please do a video on how you did the engine turning ( jewelling) on your little vise there, i’ve always been facinated with that finish. Thanks!

  44. Jeffry Blackmon on February 17, 2022 at 11:26 pm

    Very good work. Your calibrated drift and hammer are awesome! Thank you for sharing your experience. I will apply this knowledge to my grinder.

  45. Chris Colbert on February 17, 2022 at 11:26 pm

    "calibrated taps" lol – brass balls you have my friend

  46. John Fry on February 17, 2022 at 11:26 pm

    Awesome !

  47. diggerop on February 17, 2022 at 11:28 pm

    As a "kid," those were the things I would have tried, shop or field. Most likely would have used the sanding disk trick, might have even tried using a file.

  48. bcbloc02 on February 17, 2022 at 11:29 pm

    Machine in place always removes those stacked tolerances. 🙂

  49. Glenn Felpel on February 17, 2022 at 11:29 pm

    Stan, Thank you for the information and the link. Had not thought of McMaster.

  50. Tom Blough on February 17, 2022 at 11:30 pm

    Had the same problem with mine. I ended hand scraping the back of the hubs until the faces ran within 2 tenths.
