Re: [PSUBS-MAILIST] OSS Pressure hull basic layout.
Thanks for the tip. I didn't really take into account the
collar on the end cap, which would probably put the coning
tower weld right on the seam.
Is there a recommended distance for spacing such seams?
If not, does 6 inches (15cm) sound like a good space.
Ian.
