Polishing carb dash pots

I have messed with this a bit today. Seems like the answer is to use a flaper sand paper thing on a locked down drill and smooth it all so pits and such are gone.

Then useing progressively finer sand paper get rid of the lines caused by the rougher stuff.

Then polish on a wheel.

I have only done just a bit but will post a pic when done this week some time. Need to go to hardware tomorrow to get an item or two.

Keep in mind this test is being done on a dash pot that is from an extra set of H1 carbs, not the ones on Miss Agatha untill I have the system perfected.

Any ideas are welcome but it does not seem to be a difficult job but impossable with out power equipment.
 
The part about polishing without power equipment is correct. Joe Curto told me the same thing. I did mine by hand since I don't have the power equipment with mother's polish and fine steel wool. They look good but not like a wheel polisher.
 
I've read somewhere that it is possible to get them too hot and cause distortion.

I used a sisal wheel with rough cut compound, then a spiral sown wheel with fine cut compound, and finished with a loose wheel and polishing compound, then finally a hand rub out. They looked great and then I had to spend hours cleaning up the mess around the buffer.
 
Wow

Yes this is true. Inexperienced people can warp the bell out of shape where excessive heat is generated during the machine polishing. Usually this renders the bell unusable.

Interesting, Jack. I spent today polishing my cockpit surround. Same process on a different part. I started with 120 to sand out the nicks and gouges, then 220, 320, 600, 1500 and then went to the buffing wheel. Started with a cutting pad and cleaning compound then went to a soft wheel and white rouge.

Looks pretty good so far and I plan to use the same process on my dash pots as well.
 
Those are not mine, I wish. Done by a member here though.
 
I did notice they looked a little big for the Sprite... shiny though! I might whip out Rosies (the new Sprite has been named!) and try the barkeepers friend on them. They are pretty calcified though so how good they'll come up is anyones guess!
