Hello Rich, the 'jigs' or better say construction support is a unique design and will be required for the next stage of assembly. Frankly to say, and going a bit ahead, there will be yet another assembly support, the third one counted. @SAIL AND SAIL MODEL well thought about simplicity and at the same time precision while taking the next step of assembly. Great idea of those 'jigs'Until watching your log I had not realized how many jigs may be required to build a model. This is a lesson in progress with your skillful work. Rich
