Dremel 3000 Piston ring gringder for up to 5" bore I used it for Chevy SB

thingiverse

I engineered a custom-made piston ring grinder specifically for installing fresh piston rings on my prized Corvette C2. I carefully assembled the precision-crafted components onto a sturdy wooden base, which served as a makeshift platform. The result was nothing short of remarkable - it worked flawlessly from the very start!
