it might be bigger, i didnt look too closely at it, but it does look a lot like yours

you can lap by hand if you dont mind getting dirty, and your forearms will be huge like mine

they all look pretty similar, it's a simple machine.... the principal is the same on the larger machines, just has multiple spots for housings to be attached for lapping more than one at a time.



they're messy machines too.

The one we have at work is about 3x's that big and is made for resurfacing rotating groups for hydraulic piston pumps. I don't run it myself but I think they just rely on it spinning and don't add any weight onto the part that gets lapped. Maybe I should try and get some pictures.

I ude a semo-local company near me, Stahli USA. All they do is lapp. They provide graet serrvice at a reasonable price.

The key to any precision-machine tool is accuracey and repeatability. LAPPING BLocks are heavy-******. they need to be in order to hold the dimensional tolerances the are expected to produce.



The lapping table pictured is undersized for lapping an iron, (Note: I am not picking on tha mans tool, just making an observation). That block is very thin (relatively) compared to the iron it is meant to lap. The lapping machine that I have seen used has a block that is ~12" thick. It needs to be thick so that it doesn't flex and it maintains dimensional stability.
