Glad things are still ticking along in the background, I too now have a stick welder to play with and seem to be making reasonable progress?!

I saw the 10mm pitch threads too but now I have the 1605 I'm sticking to my guns. The results dean gets from 1605 are plenty good enough for me and if I can get to anywhere close I'll be a happy man!

Look forward to seeing those ali bits and pieces when there done.... Cheers joe
