I just started my bridgeport last night. With a die grinder and an assortment of bits, I'm guessing it will take me a full day for the grinding, being very careful. How long the sanding takes remains to be seen.

Check out the engne building and porting section at nopistons.com. I read the entire thing before I even ordered rebuild parts.

not too hard scary as hell though, to start off with use a carbide burr it will make thing much much faster then go to the sand paper tools.

You dont need a template for the exhaust. Open it up as big as the steel insert will allow ! ! !

Unless you have some turbo setup or some other ideas?

i would use the template for the exhaust. also, becareful that the grider does not slip out and run across of the housing!!!
