...and made a threaded hole for the outlet it was time to solder up the pump body to the cylinder.
I tried threading wires through the various holes to hold it together then using a couple of clamps to hold the parts together but neither was ideal, the wired version because it might all move around and the clamped version because it would probably mark the brass when heated.
In the end I went for a simple widget made from scrap brass sheet, a bit of annealing/bending and a couple of bits of studding seemed to make it all firm enough bit still allowed a bit of fiddling to get it all straight - a screw in the outlet hole helped to ensure 'vertical' alignment. Soldering went like a dream, taking care not to get too much heat onto the widgety bit!
First moment of truth; would it all be square when assembled?
Yay!Second moment of truth: would it actually pump water?
Yay #2!
With a vigourous pump it'll squirt the water a few feet. Considering there's no stuffing or other leak-proof stuff in place I'm well pleased with that.
Time to think about the engine.
