Today saw the 1st tests of the BWR coupling in my last blog i descibed my new design on heat welding two bottle caps together, I tested four couplings on a 7L rocket i filled the rocket with 1800mls of water and pressurized the rocket to 120 psi and left it there for two minutes no signs of cracks or leaks only problem we had was a nozzle cap washer had not sealed properley and had a small leak occured i will have to give the couplings a flight test to really know how they will work but results look promising i will post a how to video on making the couplings soon.
