Norbert Brueggen Bayonet Rings

[sunworksco]

Want to fabricate a water tight compartment.Inquiring if I can use a clear pipe sized in 114.30mm O.D. X 101.55mm I.D. or a pipe with the same 114.30mm O.D. X 96.16 I.D.

I can lathe the I.D. or O.D. to match the bayonet rings if needed but hope the rings are close in size.

Hi

I am interested in fitting these rings to a Robbe sub I am building - have you used them now and if so are they easy to fit?
