It seems its possible to make a pump from copper. But I found that many wonderful shapes and sizes of parts are available for very low prices in stainless steel!
In the above image you can see the parts. I think the image is self explanatory! I silver soldered all the parts together with Oxy-acetylene. My soldering getting better as I went along.I'm planning to put a KF/QF fitting on the top of the outlet to the roughing pump. I've just got to find a brass blank to make it from.
This is the thermos lid with the center being cut out. it was thin enough a snips would do it. Below is the M6 SS nut to hold the jet nozzels in place. Its also silver soldered in place. Before I soldered the base on! This will hold the threaded bar which keeps the jets in place.
