But wait, there's more!
I'm making my own caps from 19mm (3/4") type M pipe and and flattened pipe for soldered on cap ends.
Made a simple jig for cutting slots on my home made caps.
I used short pieces of 2 x 4 lumber and put a small spacer between them then used a hole saw to drill the 'trough' to hold the cap. Mounted thin cutoff wheel in drill press and just slide jig past wheel. Take your time for precise cuts.
BTW, I cut slots before soldering on the ends because I didn't want to be slotting annealed pipe.
I really haven't finished any one project but next post will be sight glasses/modules.
