DIY Tesla Impulse Turbine

[Toymaker]

Yes, it is a common design of Engineering connection. Easy to assemble correctly, dismantle and re-assemble. I use Gas fittings - "Calor gas" used to use Butane at cylinder pressure - using 1/8in bore copper pipe and 1/8" BSP fittings. Now use LOW pressure butane or propane (via a regulator) to 1/4" BSP fittings... for caravans, etc. But I now use copper brake pipe for my steam as the "common" pipework, with 1/8" BSP fittings, or 5/16" x 32 M.E. to suit Model Engineering commercial fittings.
Pre-assemble olives onto pre-shaped pipes, using a fitting in a vice or similar, rather than using "the job" for the first tightening of the nut onto the olive. Then use the pipe assembly on the proper job.

Thanks for the feedback K2. Your instructions closely match one of the how-to YouTube videos I've watched; the only addition to your instructions was to hand tighten the nut until snug, then turn the nut an additional 1/2 turn using a wrench, no more. I'm believe I may have initially over-tightened the nut, and the threads are now stripped from my attempts to stop the leaking. I've ordered replacement parts, but of course this means more waiting for those parts to arrive. :-(
