Sand & Polish metal stuff, TB, MAF etc.

[kool-aide]

Ok, I posted a thread not to long about about the best bits for a dremel when porting and polishing a throttle body. This is a little more general in terms of working with metal parts for a port and polish.

I am not an exp metal worker nor a Dremel tool. I was messing around with my Dremel and the starter bits that came with it. I quickly noticed the round drum sanding rolls seem to be like 80 grit sand paper and not very smooth in sanding.

What is a good progression of sand paper grit for getting metal real smooth, like the TB? I was thinking after working with 80 for getting the real rough stuff cut down jumping to like a 150, 200, then 400? I just don't know and i am making wild guesses. What's a good progression of grits? Will I be stuck sanding by hand or can i find Dremel rolls in higher grits, will google search later.

How do you polish? I have this little container of what appears to be green stuff labeled polishing compound. I have a few different kinds of cloth like bits. How do you polish? I have experimented, yet.

thanks

well the dremel site didn't seem to have anything higher than a 240 grit and on the low side it seems to be 60, not my guess of 80.

Does this mena i will be sanding by hand in a zen state of classic rock all afternoon? I was hoping for some power tool happiness, not busted knuckle manual labor.

wow, that is impressive and i haven't even watched the video.

funny, the hazardous to your health caught my eye immediately. I have a habit, extremely bad habit, of not wearing a respirator, or ear protection. I had aluminum dust every where in my garage work area. I thought fiberglass was bad.

i really need to buy another pack of disposable face masks...
