Das U-Hauneboot…
Always wanted to build a conning tower. 
High-tech circumference mark-up tool. 
Pilot holes drilled.
Dunken in das ‘Bend-O-Matic.’
• 1st try: Hot tap water.
• 2nd try: Boiling water. 
Took a little paint off, but that did the trick! 
Stepped up to larger holes.
This piece of railing was actually made as extra way back when in this thread… perfect length! 
“Haunebu Bridge to Flight Deck… We are undergoing last-minute modifications.”… 
More to come, soon…
