Following up on this - acetylene or oxy-acetylene are the most common torches people use for jewelry purposes (and nothing particularly special is needed as far as equipment goes - I’m sure what you were thinking of as a plumber’s torch is perfect, Thorn), but even handheld butane torches would work as well.
I’ve done some cleaning & organizing of the tools in the toolbox and the new cabinet we moved over to the jewelry section. Besides a torch, I think the only other main item to do over there is getting the hooks/brackets up for hanging the flexshaft motors. All other heating/pickling supplies are in the lower drawers and the bottom shelf of the red tool cabinet.
2 Questions - is the structure that’s next to the supply closet meant for the torch setup? It looks to me like it would be, but I’m not sure why it’s covered in cardboard unless that was applied for moving purposes. Also, I can’t figure out what the long wooden T structure that’s sitting on the table is for. Does it go on top of the wall-mounted brackets? I never saw the jewelry setup at Tech Shop so I have no mental picture to go on.
