Hi Brad,

I'm with you on designing and building a prototype new boring machine. I think that Tim has already overcome the gear supply problem using Toyota Tercal standard drive shaft parts and has even made up a new angle iron and flat bar prototype. The next hardest problem to overcome is obtaining new 2" and smaller drill bits.

I would love to 3D model one of these machines.

Regards

Ken Hume

Looking back to see the way ahead !
