What are you guys using as grinding material for porting. Like polishing the ports.
That's. The kind of info I needed. Thanks.The trick is to run the tool at a low speed. This keeps it from clogging from the aluminum getting soft.
Go on Ebay and you will find all kinds of cheep burs. Get the single cut ones for aluminum.
I use a 1/8" long round end 4 flute mill in a dremel run at slow speed. When making strait cuts in the back end of the case. Lay the mill down strait and you can cut with the side of the mill. Makes for a real nice and strait shot to the transfers.
1/8 " end mills fit right in the dremel and cut fast.
The finish is done with the diamond bits at slow speed. leaves just enough surface finish to keep the fuel from forming droplets.
SLOW SPEED is the ticket.
