Shiny dash pot

Here is one not quite finished. This was to prove the concept for me.

It was really nasty nasty. 100 grit sand paper, even a file to remove a few deap marks, 120 paper then 150.

Power polisher and it needs some more.

Kept a pot of cool water along side to keep the temp down. Piston slides freely.

This is not for Miss Agatha now was just a test but I supose I will finish the job.

Must be Mine Ben. heh.

This is doable at home folks, just takes some time and effort.
 
Aluminum is rewarding to polish! I did mine the same way and finished it on a buffing wheel. Look like mirrors! I also did my MGB windshield the same way. I didn't seal mine, instead I polish with mother's mag polish every now and them and keeps them looking new.
 
A method I tried a couple years ago involved a small lathe (Sherline) and a four jaw chuck (jaws opened inside the dash pot). My lathe was variable speed so machining and polishing was quite easy. I used the fixed tool rest to machine the outside to round, then removed it an used three grades of rouge to polish. Seems I saved a photo of the setup, but not the finished pot. I've since given the lathe to my son for use in bamboo fly rod making.

I also have a larger wood lathe with a both a three and four jaw chuck; it would work just as well for the polishing part. I really don't see a need for perfect roundness in the pot prior to polishing.
