Below is a list of thin walled aluminum pumps I recently polished
AD-HOC (France) polished up the nicest BTW Apex Ultralite (England) Bluemel afa Bluemel Featherweight (U.K.) the heaviest pump of them all OKE Splendid Ventolux (France) Zefal Solibloc
These look fine on the outside, but don't hold air for beans.
Anybody know where to find leather pump seals for any of these? Anybody have instructions on how to roll-your-own?
