RE: Platt Zero Build Thread
Resonding to Numblock's question:
<span style="color: rgb(0, 0, 255);">"How large of a wing will the A-Justo-Jig accommodate? And was there a jig included for the holes you drilled into the ribs?
Thanks,

Hi Bob,
The Platt Zero has just barely under an 80" wingspan. With the A6M3 wingtips option built as per plan, it will just fit the jig. I wanted the A6M3, but decided not to use such a large solid wingtip, so I extended the jig's rods out a couple inches beyond the jig to hold a last rib #11 per the A6M5 square tip version, but I trimmed it down to the A6M3 profile with a much smaller wingtip block that way.
A-justo-jig rod holes: The plan does not provde drill points for a-justo-jig rod holes. I picked a location that would allow me to use one of the rod holes for the aileron control after I pulled out the rods. This worked great.
I also had to cut two of the jig's rib braces in half so I could remove it with the wing still on the jig where the aileron control horn support goes. I had to do this so I could mount the horn before covering the top of the wing. I made a 1/8" ply plate that fit inside the jig profile and screwwed it together. This turned out to be a neat idea I think... (if they remake a-justo-jigs, as I have seen talk on other forums, this would be a neat standard feature to allow removal of some ribs early...
I hope these pictures make sense after reading this... (grin)
PS. I just found some earlier photos I made when I was figuring out where to drill...
