I made my own tool. You can too, its simple. (Well, kinda.)
I took a length of rod and cut a slit down one end of it. Then I took a
8" strip of 80 grit sandpaper (we get this stull in a big roll at work.)
It doesnt have to be 8". Whatever length. I like to start with a long
piece since it shreads itself down as you use it. Then I just use my
drill and start working the inside. The problem is you cant see too far
inside but if there are any sharp edges or burs inside, it will knock it
down to a acceptable size. Then I use a finer grit paper to finish the
work. Takes some time to do the runners and the pelnum. DO take your time
and dont spend alot of time one one area. Keep it moving. The idea is to
clean up the runners and plenum and NOT to port them.
Oh, you wont be able to do the entire length of the runners as I recall.
(might be wrong, its been a while.) just do as much of it as you can and
you DONT have to polish the intake plenum or runners. Anyways, hope this
helps.
If I missed anything, ask away.
