One last thought on holding in the J-bolts...

I installed Tee-nuts in the wing's root ribs during construction. I also used a scrap piece of lite ply under the tee-nut as extra reinforcement, but that's just me.

And for the wing dowel, I thought the instructions told us to glue it in anyway once the wing was jigged in, or did I mis-read that?

For the aileron jig, I lost mine too. I just made a new one up by copying the side view of the wing on the plans.

Not meaning to criticize here.. just tossing out some alternative ideas....

I'm on my 2nd SE now. Lost the first one to an engine flame-out on takeoff. Ran out of altitude, airspeed, and ideas all at the same time.. It was a nice plane, too.
