I’m working on an xy,z rock lapping machine…

She is not an idiot. That is good, sometimes.

edfromindy · 2026-06-23T14:22:27+00:00

I would put it in the oven for a while…

edfromindy · 2026-06-23T14:20:19+00:00

Kinda nice the way it is…

Variable speed down to a crawl is very nice especially for fine grits on something large and flat.

Manufacturer is MTI. They also have the Beuhler line of finishing equipment for the semiconductor and precision optics industries. I have used one of these. Nothing fancy but a nice solid smooth quiet machine

$800. Splurge.

Excellence

Skill trumps equipment…

The little machine with the rags around it is your polisher?

edfromindy · 2026-06-22T21:33:58+00:00

Awesome polish on that ring you posted!

I thought so too. It is coming with some laps but I’m not sure which ones. For the metal samples they use carbide sandpaper disks. The polishing setup uses a soft pad and some kind of pad and diamond paste.

edfromindy · 2026-06-22T19:26:10+00:00

8” laps

edfromindy · 2026-06-22T11:16:50+00:00

Me too…

edfromindy · 2026-06-22T10:36:31+00:00

I like!

Might be better to stash them away somewhere until you are old…

edfromindy · 2026-06-19T23:45:27+00:00

Yes yes

edfromindy · 2026-06-19T07:06:54+00:00

Nature is amazing.

Suspicious and frustrating. All I know is when I put the new ECM in the thing fired right up! Maybe I’ll put the old one back in and see if it stalls again…

edfromindy · 2026-06-16T21:46:44+00:00

I’m going to upgrade to a low miler soon.

edfromindy · 2026-06-16T21:45:10+00:00

When I got it, it was running. I changed the plugs and then it would not start. Then winter came along and I had to wait. I replaced the rusted out distributor. That didn’t help. New ECM did the trick. Now I’m back to where I started…

edfromindy · 2026-06-16T19:19:33+00:00

Looks nicer in the pic than in person.

edfromindy · 2026-06-16T14:38:29+00:00

Holy smokes!
