After fitting the turtle deck as a single piece on the fuselage and locating the flaperon feed thru holes, I marked out the hinge location and made the required cuts. Sanded the turtle deck edges smooth so there are no sharp edges anywhere on the deck. I had read that actually inserting the turtle deck into the hinge was a royal pain and as promised, it started out that way. My father's words came to me while fighting with the hinge; "A man cannot have enough clamps." So I laid two clamps (in the pic) down on the flat surface lengthwise under the turtle deck and then clamped a couple 2x4s over the top. The 2x4s were not clamped to the turtle deck anywhere so that the deck could slide underneath them but were there to keep the deck from flexing up and the hinge from buckling. Slowly added pressure to squeeze the deck with the lower clamps and the deck is now inserted into the hinge all the way. Rolled the plane out of the shop, unfolded the wings and installed the flaperons. I had fitted these last winter when I first built them up so the installation had no surprises. I also installed the firewall feed through and filled it off with high temp RTV to seal it. After the RTV set up, I installed the clenching ring and the hose clamp so that is complete.
