My first streetport in progress

[Ender]

First off, I got two junked front irons to practice on, so all these pictures in this post are on a practice iron. I'm using the Racing Beat streetport template to at least start out with, I may make a copy then modify the copy, I would probably only do so for the secondaries.

I'm looking for pointers and discussion, and I have a few questions to get things rolling.

Template over the primary then secondary ports:


Dyed:


Scribed:


Rough cut:


Here's a comparison for the size of my grinding bit, which I think is too big for some spots.... I have two carbide cutting bits, the smaller one is the one I used for this work and works pretty well (it is also smaller than this grinding bit).
