Mouthpipe bending tips

Postby roweenie » Fri Feb 14, 2020 1:00 pm

Does anyone have any "nuggets" they can pass on as how to effectively bend mouthpipes (getting it right on the first try)?

- specifically, how to gain the leverage needed to make bends at the extreme large end?

I drill a chamfered hole in my wooden workbench, stick the annealed & filled pipe in the hole, and bend. Works great for pipe that size! Can also be used for all bends in the leadpipe.

Excellent idea - many thanks! Do you have a specific bit you can recommend I get?

Just big enough to fit the pipe (so +20mm for a leadpipe).

If you have a piece of cylindrical brass tubing that fits (not-too-loosely) over the large end (offering an "extension") that's yet another tack.

To minimize minor creases and marks, a handheld wooden appliance with a roughly 1" hole (and with a 3/4" INNER diameter rubber hose inserted into that hole) could possibly contribute to speeding up the perfection of the final product via a diminished severity of marks/mini-dents.

Some mouthpipes - after bending - are going to be installation-ready, and some (without pre-made helpful very specialized jigs/molds) will not quite be so.
