The guy who invented gauge blocks used a sewing machine with a platen on it. It will take some time and some fab work but you or someone you know could do it. Way more fun than sending money to Lapmaster!
Inner, hi, I saw this when you first posted it, but have had a busy week.

I'm curious about at least taking a look at this. However, I'm not the type who can just wing it. I've worked on cars for many years, so I have a better than average mechanical aptitude than most, but to take on something like this is honestly above my pay grade.

What I would need would be some actual written out plans and/or a long video explaning exactly how to do it. Does such a thing exist? If not, this would likely be an exercise in frustration and futility for me.

Thank you for responding and also in advance for any further insights or info you can toss my way.

Thanks very much,
EG
