This is my first thread and first pics so I hope they look OK. This sidearm works very well so I thought I would Share. It is made from 3/4" and 1 1/2" L copper with 3" long sections of 1/2 copper welded to the 3/4 center pipe for more surface area. I split the 1/2" pipe in half with a band saw and welded about 1" on each end. The ends are made of flat copper washers that I cut out of a 3" scrap pipe with a hole saw. Then flattened and drilled the 7/8 hole in them with a step bit. Only fittings are 3/4" female adapters on each end. Whole mess pasted together with Silfos and a TIG torch but you could also use a acetylene torch.
