Hi Ken,

thanks a lot for the file and advice,
as for the speed of course I know that the rpm itself means nothing in terms of cutting speed , this is the reason why I had specified the diameter.

what did you made your bov from ?

Body- PVC. Spool- Derlin. Faceplate- brass. Screws- stainless. ( Most frequent use- Great Lakes = less galvanic issues.) Diaphragm, it’s cover, & exhaust valve salvaged from a Zeagle Octo+ (the integral exhaust valve makes clearing easier). 2nd stage internals from cold water rated Sherwood octo. Mushroom valves & holders from Divematics. Mouthbite- Poseidon. Only one O ring- Viton. Nametag- stuck on in jest.

Been in service 4 ½ years w/ zero problems.

5 "10ths" is really impractical in thermoplastics. The coefficient of expansion will dictate that such tolerances cannot be practically achieved. Even measuring in that range requires controlled environs, standards, and good technique.

Correct on all.

Persistence and a big trash can help.
