David,
My wife says that I can have only one submarine in my life. You do use the "steadying" tool on the DVD but do not show how it was made or its dimensions. i just ordered a drill press for the dremel (MB540 VERTICAL DRILL STAND) from Model Expo. With some modifications it might work as a platform for the radical cut I am dreading. In any event it should work for other drilling jobs.
What the devil is an angle keeper? Six channels? 1-Speed, 2&3- Bow planes, 4-Rudder, 5- Rudder, 6-

?Angle keeper
I ordered the new rudder from Revell on their web site under services. Will be most interesting to see how long it takes, my guress is four weeks minimum. That's "www.revell.com" Tab "Service and Support" and then select "Need Parts?".
Best,
Walter
