Brief Description: Rear tie-down block, vert stabilizer
I constructed the tail tie-down block, took careful measurements of it's position in relation to the bottom of the fuselage, then clamped it into place on the vertical stab's aft spar and match-drilled pilot holes in #30. I then primed the block and drilled the hole in the fuselage bottom through which the tie-down bolt will pass.
