Re: Port Job tools

[abrahamk]

Listers,
For a cheap, but effective mild port job I used a normal electric drill, one set of 
steel grinders for cutting and one set of carbide grinders for finishing.
probably about $20 worth of grinding bits.
These type of bits don't like valve guides though - stick to the alloy.
The other disadvantage is the time it takes, but this didn't bother me too much.

I got a dud head from an engine reconditioner for practice and used a band saw to 
section an intake and exhaust port to get a better idea of where and how much meat to 
remove.

I was absolutely chuffed with the final result especially with just the extractors and 
no exhaust :)
You cannot compare it to the Bluebird engine it was originally - definitely worth the 
effort.

Regards,
Nick

Errol,
I've found that even the cheap high speed steel burrs do the job with
ally.Anyone in Perth, WA Salvage had them on special for $2 each.
