After finishing the seat ribs I started in on the forward structure. The plans are a bit lacking in this area and could use some clarification for sure. After fixing the main spr carrythrough in position I cut the lower longeron (The fuse is upside-down in the jig so this longeron is on top). I then cut and trimmed the second crossmember that attached to the engine mount. This is where things get a bit confusing and unclear. I think I have things right, but I will ask some other builders berfore I drill anything.
