Atlasdoc2, Did you ever come up with the plans for the Dahlquist stands, I have a copy of those plans for the three post type stand

The top plate has a bit of an "L" shape on the back side which is a bit hard to visualize on the plan. If you look at the top plate on this link for the solid type stand, which I don’t have plans for, you can see what I mean:
