Terry I like that did you put dowels at the join of the uprights to the base plates to make sure they stayed at 90 deg and attached, also did you consider putting the slots for the bolts in the base plates so they would twist to match the shape of the fuselage or is that not nescary, I will be building one like you have shown and wondered about the actual construction methods.
Methinks a wing jig could be built in the same way with removable attachments to the uprights for different leading and trailing edges, being as I cannot manage to get an adjustojig at a reasonable price last one I saw on ebay was sold at over $300.00 sure wish they would start making them again or one of the "cottage" industry model parts suppliers would come up with something as good.
