Semroc Saturn 1B, Build, OOP #KS-1, Part 40 Notching the H-1 Tubes

Four of the BT-51N tubes have to be notched to fit around the four engine cluster mount. Notch only four!

Mark the tubes for a slot 3/8" wide by 2 7/8" tall.
The long sides were marked in pencil using the aluminum angle.
The top mark was penciled using a wrap of masking tape to be sure it was square.

Use the aluminum angle as a knife guide to make the vertical cuts.





Here's four of the eight fuel tube engines, cut to fit around the four engine mount.
