Fast or slow for flasks?

[Dug]

Hi;

I just got started into tumbling bottle exteriors. I have a 2 speed set up and know that low speed is for square/rectangular bottles. I also realize flasks are like paddles and know to leave clearance in the canister wall for them so they don't jam up the copper and break. With the high speed being pretty stinking quick I'm concerned that the dynamics of the copper movement would change. What speed would you run flasks, low or high?

I have zero experience tumbling bottles. I think there's one or two people on here who have and could help you out. Maybe they'll see this post and chime in

Slow. Very slow. The glass is very thin on most flasks. Trust me you don't want that copper slapping the glass as it tumbles. It takes longer to complete the job but well worth the slow methodical tumble. Jgas.

Figured as much, thanks for the input.
