I have cut, drilled and installed a 3/8" piece of ply under the plastic landing gear mount on my NexStar. Now I need to repair the spar that is broken. You can see it in the pic. On the left side of the pic it's broken and about 1/4" of it is left behind the bulkhead. On the right side it's broken almost flush with the bulkhead. I know I shouldn't butt the new piece up to the old and glue it but it would be difficult to make a diagonal cut on the right and impossible on the left without cutting more of the balsa out. What is the best method for fixing this spar without tearing too much else up or should I remove more of the skin for better access?
