Turn a small drill press into a Bore/ Hone. Bolt it to the top of your engine block & do your own machining .

Is that shots, on the rocks or frozen drink from a blender?
As far as the Bamboo just remember you have to keep it well coated with coconut milk. If not it will become dry and brittle. You do not want failed equipment
After reading your chop a piston thread.
I had great idea for a tool that makes the need to bore and hone and new pistons a thing of the past.

I am working on your blanace problems. Will update you on progress. Not sure if should reveal my 2 new machines for the good of the automobile world. Or get a lawyer involved. It could be a revolution in how things are done and be worth a fortune.
So do I share or get lawyers involed to register?
You should share your ideas. You may pick up some good input for improvements from this crew of geniuses.
Just like the idea of using coconut milk. I was going to use bear fat for a lubricant.
