Saul,
Thanks again for the tip. Glad your enjoying the build.

The plans give you the option of a rear hatch. I decided to do the hatch before applying the sheeting and it was easier to handle. Cut out per plans sand it a little smaller so there when both surfaces are covered there is enough clearence. Then used the 3/8 brass tube to "cut" a hole in the aft end. glued a 3/8in dowel in place then sanded flush when dried. Drilled the dowel a little larger than the 6-32 nylon screw. added a hardwood block and hardened balsa sheeting undersurface where the "tab" will press against it. Drilled and taped the block and hardened the threads with CA then taped again. When the sheeting is applied the triangle stosk supports the sides of the hatch.
