Piker Porting (Intake Manifolds)

I’ll be trying different techniques, speed, pressure, angles, cross hatches and so forth on a scrap plate of aluminum and see what I come up with. I have a good bit of woodworking experience with rasps (and as I’ve mentioned, use on aluminum) I have zero experience bending a burr, notching teeth and control techniques. So I’m hoping the rasp will work.


It doesn’t matter how you get the finish. As long as you get the finish. I mean hey, if you can get the correct finish with a toothbrush all that matters is you got it. IMO, there is no right or wrong way to get it. I hope the rasp works for you. If it does, I’m going to buy some and see how bad I do with them lol.
