Kustomizer
I had one of those in a past life, running a bunch of Bechler screw machines and I thought it would be "just the ticket" for touching up tooling. Lets just say it was not nearly as useful as I thought it was going to be. A VFD on a Baldor / Rockwell carbide grinder ran rings around the Leonard.
I don't have an ocean of screw machines to ride herd on anymore.
In my home shop I have what may be about ideal. A copy of a buehler lap, might have been a lapidary tool. It takes 8"-9" inch aluminum discs and whatever fixture you wish to apply.
Discs drop over a square spud and get held on by a small hand wheel. I have perhaps 2 doz discs with PSA Reagalite, Trizac, and so forth. Leather and canvas laps, plated diamond. All uber cheap from ebay. It does eveythng from touching up a miter for a picture frame, facets in stone, dressing a brazed carbide turning tool, honing a plane iron or a sushi knife. And no larger than the leonard
Disc speed variable, motor controled with an on/off foot switch

You need to find wheels for the grinder-r-lap as well. Glendo only sells 250 and 1200 grit at the moment, not 600 like they used to. Our scraper hand seems to get by with these two grits. I recently got him two wheels and with shipping the total was just over $500.

Thanks for the information, much appreciated! I would have assumed that would be perfect for that task. I have a small CNC screw machine with overhead gang tooling that I have used brazed carbide tooling on from time to time. Also at $25 a piece I will often resharpen cut-off inserts if I am using them on easy to machine materials where removing the coating makes no difference.
I currently am using a precision bearing bench grinder with diamond wheels on it and free handing. Those free hands aren't as steady as they used to be. I saw what Kustomizer was looking for as something from the cam auto screw machine days like an Agathon 175. I guess I was wrong.
I was going to say "Put me down for one after Kustomizer" now I won't.

I have one I would part with. Not sure of the condition, I do seem to recall the wheel on it is junk. I purchased it some time back and then ended up running across a really sharp AccuFinish.

Useful on other machines besides screw machines. We had one at Webster, I used it a lot. They are very handy for doing a nice final finish on brazed carbide.
But then, I'm happy to use HSS when it's suitable. Guess I grew up too long ago, back when men were men (and sheep ran scared).

Got one , almost your neighbor being in Oregon. Bought it years ago and never used it. Time to move it on. have the original directions. Got probably 6-8 of the steel rings that have the diamond grit on them All are worn out. I was just going to clean them, get the various diamond grit sizes and redue the faces. there is an article in the Home shop machinst, or projects in metal on how to do this. Even have the dimond material to do it but, ya know, never found time. Any way if you are interested shoot me a number to call on the private line here and we can talk if interested.

Two prospects is pretty exciting, I didn't realize until my homemade one broke that they are not made any more and of course that is because they evidently are not really used much either. Thanks for the replies, now to see if I can buy one.

I did not get your message. I tried to send you a message and got a notice you have exceeded your exceeded your stored private messages quota. I can't remember how many messages you can have but it not that many. To be safe I also cleaned out my inbox and sent items.

"Wanted" to buy.....so you don't want to buy one anymore ?
I think you are correct, I think one of the two, or perhaps both will be mine soon, I am hoping anyhow.

I know you're not supposed to, but my buddy used to sharpen his pocket knife on ours. It sure made for a sharp edge. Don't know if it would damage the wheel to do occasional light finish work to hss on them ?

I bought a new Baldor carbide grinder about 45 years ago when I began using carbide tools.
Then I got a good used Leonard Grind-R-Lap and cleaned and painted it. I liked it better than the Baldor for most work. A few miles from me, Continental Diamond Tool, New Haven, IN, made me a pair of laps for it using my steel rings. Worked great for brazed carbide and extending the life of inserts. I very seldom use the Baldor anymore. The Baldor is single phase, so no way to slow it down with a VFD.
Then, years ago, I got a new Glendo Accu-Finish and stopped using the Leonard. After using the Accu-Finish, I stopped looking at carbide grinders, though I did buy a spare Accu-Finish to get the additional wheels it had.
I turned the Leonard on just now and noted the lateral motion is not working (it used to). Maybe I will turn it over and look in the bottom to see what got stuck.
