Turn a small drill press into a Bore/ Hone. Bolt it to the top of your engine block & do your own machining .
I am having a party in a few weeks. You think I could get some of that stuff that's fueling all these WAY OUT THERE ideas?
Precession boring is done with a single point boring bar 99% of the time. It take horsepower to turn even a single point bit.
The only people using more than one cutter at a time boring are the OEM engine companies, and they have high powered custom built machines.
