RE: Pay It Forward Build Thread!! Sig LT-40 build
Doing good Reggie. Pictures are OK, could use a little more light it appears. Good to wsee you using the 90 degree brackets and pins.
Try this - put a T-pin on either side of the spar and stretch a small rubber band between them over the top of the spar. This will PULL the spar down snug. Do this in about every other bay for best results.
