Polished Pintles

The canoe build plans helpfully note that gudgeons and pintles might be hard to find so the builder should braze them from brass plate.  It has been close to 20 years since I have had to braze anything and back then I had the luxury of a fully equipped workshop with an oxy torch.  I started by bending some 1.6mm cartridge brass around a 3/4inch former so that it would fit snuggly around 3/4 copper pipe.  Initially I tried to use a small portable gas torch to silver solder but to no avail.  It took the propane torch with the 9kg gas bottle to provide the heat.

The gudgeons have the 3/4 copper pipe and the pintles have a turned brass spacer.  The plan is to use allthread to mount the pintle shafts.
