Tip: Simplified method of attaching skirts to slider canopy

[MrNomad]

Amongst the more difficult aspects of building a 9A slider is the canopy. We wrestled with the C-660 skirts over and over again trying for an easy way to get them to line up. We tried inducing a curve and spoke to Ken Scott at Vans several times. He was very helpful but we still could not get it right.

After several "abortions" I think we have come up a simple way to get them to fit. In fact, the first one took an hour but the second took only 10 minutes. Essentially, if you think of the C-660 as a template to be rotated vertically before final attachment, you can achieve the complex bend. The C-660 will adhere to the side of the airplane w/o bending it, stretching it, or going nuts.

After many days of wasted effort and aluminum, we did it as follows:

1)Using the first 10 holes (front to rear), affix the C-660 to the horizontal canopy rail on the slider. The base of the C-660 should be above the rivets per the plan. In our case, the C-759 inner canopy skirt had already been drilled and aligned to cradle the lower edge of the canopy plexiglass.

2)With the first 10 holes secured with clecos, lift the aft end of the C-660 approx 1/8' to 1/4" and clamp it to the C-759 which was already clamped to the canopy frame. The "lift" will cause the C-660 to curl and align itself vertically to the edge of the fuse.

3)With the C-660 firmly clamped to the C-759, remove all pieces and drill the C-660 using the previously drilled holes in the C-759. 4) Using a shear, trim the upper edge of the C-660 at the aft end where it rises above the C-759.

Voila, you're done.

Another way to do it is tape the skirt on and draw lines about 1 1/2 inches apart for the entire length of it parallel to the longitudinal axis of the plane. Remove the tape and gently bend the skirt over a 4 inch piece of pipe. Using the lines as bending points. Perfect fit every time
