RE: Zroli 20 (?)year old 1/2A 42"span Jenny
On my Sopwith Pup, I did something similar to Bipe but used a thin piece of brass sheet stock. I cut it about 1/4" wide by 3/4" long and bent it into an 'L'. I then cut a small slot about 1/2 way up the rib the struts attach to and then covered the bottom of the top wing and top of the bottom wing. Slit the covering just big enough to slide the long leg of the 'L' down through and then put the short leg in the slot in the rib. I put a small piece of balsa to sandwich the strut mount to the rib for reinforcement.
