Hi Terry, I am very inpressed with your build. What did you use to bond aluminium stock to particle board etc. Regards Dale

I do not use 3000 psi, I have done jobs with as little as 50 psi to blow out 1mm thick steel tube and...

Hi Keith5700, Don't let fear hold you back. I have made tapered pipes by this method and repaires expansion chambers after removing all of the combustibles from inside the pipe. Pressure and temperature control are the only skills that are required. Basically the metal is drawn...
