I have wondered about it since I saw it on Bill's site and dismissed it as a typo. |
Well... Hmm....
Just measured my SPEV from three points --- OD= approx 1.024" -- can't get wall thickness.
Measured the tube I got from BMS that was identfied as BT-52 -- OD= 1.044" wall=0.018"
Tube from Semroc Mark II -- OD= 1.045" wall=0.018"
So it looks like the tube that Bill advertised as BT-52 was actually ST-10. I said it fit the parts well, but they did fit easily, and not at all snug.
