The jig on Drawing12A is a starting point as it depends on whether you plan to build one wing at a time, both together and the layout of your workshop. The only thing I've learned from other websites is to make sure the distance between the posts is 114".
Simon and I have built a jig that will accept both wings so that if I decide to build both together I can.
Points:
* For garage ergonomics I needed to build the wing jig 90 degrees to my garage door * The garge door is electric up and over door so I couldn't build to the ceilng. * The final rigidity of the jig came from a vertical support which screwed to the door joist
