I concur with Jerry! Probably the best $10 you will spend in aviation
Video would be nice as well so you can actually SEE what they talk
about in the book. Depending on your time frame, you can actually do
some practice covering if you attend the Oshkosh airshow. Polyfiber is
there every year and they teach basics in about an hour long "crash
course". It doesn't cover everything such as silver coat and
doping...just fabric attachment and shrinking, but they mention the
entire process...

Polyfiber has a book, I think $10, well worth it, also a video. I put the
bottom on first and glue to the leading and trailing edge spars. Wrap it
almost all the way around the tubes. The over lap the top. Then at the seams
cover with 3 or 4 inch tapes. This is the standard polyfiber process. Get
the book and video.

First, I would use a proven system such as (Stits) Polyfiber.

Here is what they say (in the Tech Questions portion of their website)...

When gluing fabric to fabric, how much overlap should I use?

Normally, a 1-inch overlap is sufficient. However, on the leading edge

of any wing section you must use a 2-inch overlap.

I don't believe you would have to sew the upper and lower coverings
together at the leading edge (and as I recall, the leading edge tube on
the Riser is something like 2" in diamter, so you should have plenty of
area to get a full 2" overlap and still even have metal under the lap to
really hold the fabric on). This IS assuming you use polyfiber and NOT
jacket lining material! I'm familiar with the Easy Riser. You only have
4 wing panels and 2 rudders to cover. I would pay a little extra and use
industry standard materials. Plus, if you use a complete system such as
polyfiber, you won't have any compatibility issues. I'm sure you would
hate to find out that the glue you used to attach the fabric eats the
fabric away after 6 months, which would no doubt be discovered at 200 feet
during your climbout....

Definitely check out the polyfiber website!!

Good luck with the project! It would be great to see that vintage
ultralight stuff still flying!

I'm using thin polyster fabric on my Easy Riser, and the old fabric was
sewn together at the leading edge. The trailing edge was just glued to
the frame. Can I simply glue the leading edge tubes to the fabric, as
well as
the trailing edge? If sewing is necessary, how do you get two 16'
sections of coat lining material sewn together?
