Well I have been playing with my dremel and that thing can polish just about any metal to a fine glass finish. Just wondering if anyone here has tried it yet. Oh yeah I have seen those kits for polishing in a jegs. That would probably work well with the dremel right?

You would be old and gray before you got the job done with a Dremel.

The kit you can get from Jeg's or wherever is made by Standard Abrasives; it contains a number of "tootsie rolls", an arbor, some Scotchbrite sort of things for polishing, and a few other goodies, including some pretty good instructions. I've never heard of it before. But it works quite well, when used with an air-powered die grinder.

A dremel would probably be better on just the polishing right?

Only if you want to make a career out of it.

You can buy a real electric die grinder from Sears for about $100.
You can build a speed controller with a 110 A/C home overhead light dimmer or fan speed controler available in any electrical hardware store. Don't get the ones with the radio interference filter.
(they burn out). about $10

use an die grinder and carbide files and you'll get most of it done in a few hours.

If you don't have an air compressor,maybe you could borrow one or rent one....You can get a die grinder at Menards for about $15,a good carbide bit for around $25,and the Standard Abrasives kit for about $38....
I did all the above and it took me about 13 hours to completely hog the snot out of my L98 heads...It made a big difference in performance..

WELL, I've done it both ways and prefer the dremel with a flexable shaft. I bought some carbide burs at the farm store near by. They work real well, and cut fast. I don't like the moan of the air die grinders myself. The plus for the dremel is you can slow it down or speed it up with a touch of the switch.

combined air die grinder and dremel tools, and a lot of rubbing with scotch brite. Took a long time but in no hurry. Mirror finish on bowls but you cant help hit the valve seats. Got them redone. Opened up the pushrod holes for clearence for 1.65 rockers while I was at it. Standard abrasives tools didnt help much (I have my own), but they have a good "show how" in there website. worth checking out.
