Speedmaster intake porting. Hopefully I can make something out of this

That’s a burr finish in the pictures and will be going on just like that.


I like that. I read where some guys say it’s quicker to burr finish, but I can’t just burr it and let it go. It looks like crap on a cracker if I try that.

I have been working on my burrs to get the right amount of “bend” to it so I can get the surface finish I want and still be able to hang on to the the damned thing and be able to use it for more than 5 minutes. I think I have that worked out.

I still can’t get the final shape I want without a paper roll first. Then I can go back over the paper roll finish with the burr and get what I want.

Doing it the way I am damn sure ain’t quicker, but it’s the only way I can get a decent finish with a burr.
