?? On Polishing Inner And Outer Hubs
- Thread starter Eliminator Racing

Recenyly I have tried cutting a q-tip in half and putting it in the dremel. I used the rotating cotton swab to apply to the inside and outside bore with Step 1 and Red Rocket. I think burnish with graphite. I dont think I am hurting the bore with the q-tip and it also helps get the extra polish off.

A Q-tip's shaft can be to big. Combine that with the speed of the dremel and you'll melt the bore.
I have the same tooling marks on the inner hub. Tried Novus 2 but it just didn't cut it. Think I'll try the 1,000 - 3000 grit suggestion and see if I can find a little more speed.

Just remember, there can be a very fine line between gaining speed and wrecking parts. I've done both. /images/boards/smilies/thumb.gif
Yep, did that! Melted a bore using my drill and a qtip to polish the outer hub.
A costly lesson.

I was referring to only letting the cotton swab (not shaft) rotate in the dremel while pressing gently against the inner and outer hub. (with polish).
I too have stripped some bore off my wheels with a q-tip shaft on my dremel. As of now I use a q-tip in the dremel with DD4H step 1 polish for the bores. My only option for using a q-tip shaft would be to use my drill and hope that I can hold the wheel with one hand and gently squeeze the trigger with the other so that I have a moderate speed (my drill cannot be set at a speed and its controlled by the trigger.)
Am I better off sticking with the dremel and a pipecleaner or going to the q-tip and my drill (perhaps after practicing on stock wheels?)

I use that 1/8" foam sheet from Hobby Lobby. I cut a strip 3/8th at the top down to a point at the bottom, 3 or 4 inches long.
Then I use DD4H #1, pushing the wheel up the strip (which is turning slow in a hand drill) up to the point where the foam strip starts to buckle.
The buckle spreads out and polishes the inner and then affterwards the outer hub to a fine shine.
I finish this up by doing the exact same using Brasso on a new piece of foam.
Then I use Red Rocket the same way as a third step.
Both hubs turn out as shiny as a mirror, except black shiny.

Regarding the outer hub polishing, any ideas or reasons why it's best to not over polish this area? Does it mainly boil down to "the results prove this" or am I missing the big picture. I can see if someone were to be concerned about over heating or deformation but that's not the way this hobby works. If it leads to a faster car by highly polishing this area then someone would just take there time and do it right.
