Steve Bralla makes an eccentric assembly tool that you insert and then give a half twist or so to pull the wings the final bit in. I've used it on our ASW-20 as well as a DG-100. It's great and he sells them for $75 I think.

His contact info:

I don't know if the measurements are correct for your need, but he should be able to provide you with an answer. Great tool in my book.

I have heard of but not seen such a tool. It would have 2 sections

that rotate independently and are crescent shaped.

Two handles would protrude. Insert into the spar pin holes that have

been placed roughly into correct position so that you can see through

both, turn handles to 180 degrees apart aligning the holes, remove and

install your spar pin.

This would be a great help for one-man rigging. Does anyone know who

sells these or does anyone have a drawing of one? My pins are 30mm

diameter and 100mm long but a drawing could be changed for any size.
