There was, several years back, a youtube video of linuxcnc machining the alu block for the TRO racing engine Toyota was leasing to serious racers. Very impressive video as it started as an alloy casting they found a V8 engine block ready to have sleeves fitted and the rest of the parts stuffed into it to make one of those high output engines. I assume it was taken down because it showed too much proprietary stuff about how it was done. Very impressive video at the time.

See the README on my web page & pull what you need. Hit the site in my sig, add "lathe-stf/" to the address bar and then click on the linuxcnc4rpi4 link.
