Decided to temporarily install the elevators so I could get a measurement for trimming the lower flange of the HS602 aft spar for the elevator horns. There's also interference with the counterbalance horns and the 601PP skins that will need to be dealt with.

The print doesn't call out a dimension for the cutout of the 603. Basically it just says trim as needed to allow the horns enough unrestricted movement to get appropriate elevator travel. The only way I could see to precisely locate this was to temporarily install the elevators so I could see how wide to make the cutout.

When I bought this kit used, I got a couple of big tubs of random stuff with it, including an envelope of temporary hinge pins. Turns out that until the skin interference is trimmed, the elevators are stuck in trail and there isn't enough room to get much access to the hinge points, so after fighting with this for a few minutes, I went to the hardware store, bought a stick of 3/16 brass rod, and made my own rigging pins with a handle sticking up that made it a lot easier.

The side to side dimension of the control horns turned out to be almost exactly 1.75 inches. I wasn't sure how much extra gap people typically leave on each side, so I called Vans. Sterling said most people shoot for maybe 1/8" there. I also asked him how much gap to leave around the counterbalance horns because I couldn't find it on the print anywhere, and he pointed out that It was in the top left corner of DWG 3 and calls out a min 1/8" gap.

Started laying out dimensions, so I'll try to get his stuff trimmed up tomorrow.

Will probably also trim up the lead weight per print while I'm cleaning up stuff, but there's nothing urgent about that.
