I will be ordering some forged pistons for my next build up. Just wondering if anyone has a good easy method to polish the piston tops?

 

one guy posted here a little while ago, chucked the pistons up in a mill, and used one of those abrasive nylon brushes and ran it over the piston top.

I just used a needle file to remove the sharp edges, then went over it all with 180grit sandpaper, then 400 grit. I could have used a felt bob in a dremel, with autosol polish too, but I didn't. A cross buff in a dremel/die grinder would probably work too. I have hyper pistons, which tend to have more shine due to the silicon I believe.

 

Thanks for the reply. Going over the sharp edges is a good idea. I was already planning on the sandpaper route. That is what I will most likely end up doing.

 

bench grinder, buffing wheel, rouge (sic?) or emory compound

 

sic? is that like "sp"?


damn, I wish I would have thought of that when I had mine out....
