Ghetto tool post grinder :)

[Janderso]

I saw something similar on Pinterist.
I used some scrap and put this together.
It’s rock solid in the holder. There are flats on the front of the air tool and I put a second 10mm 1.50 dog point. Much more robust than a Dremel.
The air tool has 27,000 RPM.
I just need to find some 1/4” arbor stones to test it out.
Total expense, $30. Much better than the >$500 alternatives.

Very Cool!

I made a similar one by boring out a piece of pipe and welding a piece of key stock to it for clamping in the tool holder. The last thing I did with it was cutting a couple of Brigg & Stratton wrist pins shorter by using a cutoff wheel on an arbor. &*^#)(*$& Briggs changed the wrist pin length when they redesigned the pistons and then didn't include them with replacement pistons. Then they did not release a part number for the new wrist pin, instead listing the old, too long, pin as proper for the new piston.

The cutoff wheel sliced that hardened pin like a hot knife through butter!

The diamond point dressing fixture was more complicated than the adapter.

I was wondering how I was going to dress the stone?
Just pocked up a set at Home Depot. I have two coming from Dumore as well.

I bought a 3/8" diamond point and fabbed up a holder. It is used on an Atlas lathe, so the flat ways made it easy to mount to the ways. One key point is that the point needs to mount at an angle in order to limit the chance of knocking the diamond off its mount.

Love to see a pic

I might add, that you can stick a piece of velcro around the lever to keep it on. Use a cheap ball valve to turn it on and off so as not to introduce your weight and affect the grinder.

I wouldn't call it ghetto, it's a decent solution.
BTW you can true your stone by putting a diamond in your chuck and running the grinder. Don't spin the chuck.
DOOOOOOOO cover your ways where ever possible. If you can keep a vac sucking up what you can while running.

I find my tool post grinder to be invaluable when I need it. But I don't need it often. I thought I would need it more than I do.
Had I known, I probably would have gone down the road you did.

That's what I did. Boy, Those Home Depot stones are garbage.
Waiting for the Dumore package.

Yeah,
I don't like the grit at all. I had all the ways covered but still. I won't use this unless I need to
The surface grinder will get the bulk of the business.

I used a HF extended nose die grinder and made a bracket to mount it to my toolpost. I needed to grind the jaws on my 6-jaw chuck and the setup which was far more ghetto than yours worked great. I did not think of using a piece of velcro for holding down the lever. I used a nylon wire tie that I slid on and off, it got the job done. Your set up is well done and quite far from ghetto.
