You didn't work all the way up to the UIM?

You mean cut from top to bottom? I did what I could, the bit wouldn't let me in too deep.

Forgot to mention, I did go in from the UIM side and went down. I got a good bit of material out of there just doing that. So yeah, for the most part there'* a good bit taken off.

You work the ports from both sides.

Pages 1, 2, and 3 all have detailed pics.

So you think I should remove even more material? Brb... gonna get a pic of the LIM from the top side.

Are you talking about possibly removing that lip you can see on the top?

I think he might be referring to the polish part of porting and polishing?

To get the roughness out of the ports.

Only thing I can really use is the drum sander bit. That thing likes to tear to shreds quickly though, not sure why. And I think he means smooth, not polish.

Semi-smooth. Same finish as below. Get that dark rough crap smoothed out a little bit. You need a large carbide cutter with a rounded end. My favorite is a teardrop-shaped bit. The cutting head is teardrop shaped and is about 3/8" in diameter.

Better?





Can't get into the deep stuff without throwing the hole out of shape lol. But you can't feel it, so it'* ok.
