Is the surface left by the diamond tip Dremel bit smooth enough to not snag whatever is riding on the pin?

Is there a special stone to smoothen the ground surface to match the finish of the rest of the stock fuel pin? Where can i get it?

 

The 1 time I did it, I used a regular angle grinder and a vise. Diamond tip is fine.

The key is a few very light finishing passes on whatever you use. Take it from an ex-machinist.

 

I just use a dremel with the little sanding wheel thingy. My dremel came with what looks like an 80 grit paper for it. Works dandy.

I usually take the majority of the material off with a 4 1/2" grinder first to save time. then clean it up and do the fine tuning of the profile with the dremel. works perfect

 

I hand finished with whatever emery cloth I had for 15 minutes or so by hand. I think I had 150 grit or something

 

I'm new to all this pin stuff can anyone tell me if I get the Denny t state two pin will it kill my mpg even if i try drive it nice?
