I setup the right wing twist jig and spars on two saw horse that I had my bench on. These guys are perfect! They have a notch down the middle for the jig, and two notches for 2x4's that just happen to fit the angles for the tip jig, and are just narrow enough for the angles of the root jig to straddle. Sometimes even a blind squirrel finds a nut.
I'll order two more on Amazon tonight and then set them up with a level and a laser line.
