I just got off the phone with Dan Stewart of Stewart Systems. I asked Dan for advice on the best way to handle the under camber covering. First though, I measured the farthest distance the fabrik would pull away by running a string from the leading edge to the trailing edge on the wing bottom. The greatest distance was 9/16 inch. Dan said this distance was not great and many builders simply pull it in during the rib stitching process, well after the final shrink. He said you can also follow this sequence; lightly glue fabrik to the bottom capstrips by precoating them with EkoBond then tack with heat after the perimeter is glued down, lightly iron (about 200F) just to get out the wrinkles, rib stitch, then shrink at 250 then 315. This is almost exactly as described in the PolyFiber manual. Thoughts or better ideas?

When you then ribstitch it pulls into place with no problems. I did use anti-chafe tape on all of my ribs. In the hot weather we had this summer the tape did not stick very well. I was concerned that in the undercamber area it would shift before I was able to anchor it permanetly with the fabric and rib stitching. What I wound up doing is dabbing on a little EkoBond every few inches on top of the ribs. Once it dried, the anti-chafe tape stuck very well.

I can locate one for the coil side, but not the oil cooler side. What is the reason for this shroud? I will be using cub style eyebrows for the air inlets. On the distributor side the shroud is necessary to force the cooling air down through the heads. Since I am using a stock folded 12 fin cooler, wont the cooler do the same for the left side? I have made shrouds for the left and right sides of the cooler. Does the shroud on the oil cooler side stop the air from going between the rear cylinder head and the oil cooler?

He then heat shrunk the fabric at 200 degrees. Then he rib-stiched the entire wing, pulling that 9/16-inch in with the stitching. Then he heat shrunk at 300 degrees.

The left shroud goes between the #2 cylinder and the oil cooler (I also have the 12-plate cooler). You must have one. The shroud forces the air down through the fins on the #2 cylinder. A shroud should also be built with the opening at least as large as the area of the top of the oil cooler to force cooling air from the top of the engine down through the cooler. Clear as mud?

Obviously, many different methods work and it's not a big deal. This thread should be helpful for other newbies like me.
