The thread size of a common crank arm extractor is a pretty good match to the Silca pump end cap. I used an extractor with cutting edges ground in the threads to tap the pump barrel after cutting down. The piston shaft can be cut and the leather plug/piston recrimped back in place. Just take care during pumping. The piston can pull of easily if you're not careful.

I recently bought an old Silca Impero plastic pump on the assumption that , as I have been told by a knowledgable bikie, it can be cut and re-threade d to fit my renovated frame. I know re-threading the plastic barrel could b e dicey. Anyone have any ideas about how to go about this? What kind of thr eading does it have? I only paid a few bucks for it so I can afford to bite the bullet if necessary.=0A Dick Howard=0A Salem , Va.=0A USA
