I read Wirejock's description of how to mark the block along with the plans. Got reference lines on the right block and set up the drill press to do the compound angle required. Stepped up hole sizes and final hole fit pretty well. Clamped the canopy shut and made marks for the left side block. Drilled the hole to help hold canopy in proper place for closing. Clamped blocks and canopy will close on both sides with a little help.
