Paul again..Evidently Yahoo thinks my answers to your post are spam..
So I'll repost a quick answer here.
The summery is this...
I agree with the poster about the home built or experimental aircraft
folks having the dacron. It may be available by a trade name there.
Also I would consider the ballistic nylon as an alternative if
available. To that end there is an article in issues 205 and 206 of
Woodenboat magazine (latest two issues) about building a skin on frame
boat using nylon. Page 38 in issue 205 and page 44 in issue
206...Issue 206 deals with the covering and finishing of the boat. I'd
do a quick test with the "Heat-n-Bond" on the nylon if you can find
that locally. I bet it will work just fine. Perhaps easier than the
staple and sewing method used in the article..(although I've never
tried sewing and staples) You can go to their website,
www.woodenboat.com and order issues from the "store" link. Also while
there, go to the forum and register (free) and post your question
about availability of Dacron in Australia. There are several folks who
post there from Australia on a regular basis. Put the word Australia
in the headline to get their attention :). Perhaps they can help you
find it locally.
Hope this helps. Keep us posted on the progress.
My apologies for the multiple posts. Got tangled up in Yahoo's quest
to eliminate spam I guess.
