When I ordered my first batch of materials some time ago, I ordered a roll
of 1.7 oz x 45" peel ply from AS&S.  About a year ago, I reasoned that I
wanted to make sure I had enough to do the fuse inside and out, so I called
and was told that they had discontinued the 45" stuff and only had the 66"
width.  It was wider than the rack I had built to hold cloth, but I figured
I could work that out.  I never opened it until the other day when doing the
4ply uni lay-up on the longerons.  What AS&S DIDN'T tell me was that the
wide stuff is 2.7 oz, making it CONSIDERABLY stiffer than the other.  It was
immediately obvious that there was no way this stuff would lay down over all
the complex curves of that lay-up.  Fortunately, I still had enough of the
other to complete the lay-up.

Enough rambling, the question:  does anyone use this heavier stuff?  Maybe
for flat or slightly curved lay-ups?  AS&S now says they have the light
weight peel ply back in stock so I can order more, but don't want to mess up
a large lay-up trying to use the heavy stuff if it won't work.

Thoughts?

 Russ,

If you cut strips " Slighty"  on the bias (i.e. 10-15 degress)  It is much more
pliable and thus easier to lay down in curves etc.  Large layups cann also be
applied on the bias.

Russ,

I have the same heavy peel ply that you spoke of and I have found it
good in most areas. When I heat it with a hair drier it seems to take up
the correct shape albeit not as well as the light stuff.

See you at Oshkosh again this year if you are going.

Thanks to everyone responding to my peel ply question.  I received a lot of
good advice, most of it sent directly to me rather than to the group.  The
consensus seems to be that the 2.7 oz is fine, just a little trickier over
curved surfaces.  I think I'll save it for the wings, strakes and other
relatively flat surfaces.

I'm planning my first order of materials.  I am planning to order the kits
for chapters 4 - 7 plus some other various supplies like epoxy and some
tools.  I believe I have it all figured out except for the peel ply.  I
haven't done chapter 3 or any other composite work before so I'm not too
sure how the stuff is used yet.  Chapter 2 mentions 4 rolls each of 1" and
2" rolls.  I've seen mention of people using 4" and 6" rolls.  What size and
how much should I order for chapters 4 - 7?

Thanks

I'd recommend ordering the 4 rolls of 1 and 2 inch, plus a few yards (say
10) of the 60 inch stuff sold by Wicks.  These supplies may well last you
past Chap 7, but you'll be able to get the feel for each of the widths.  I
use the 60 inch stuff most. You can cut it as needed.

Rick,
    I have had good luck with bolts of white dacron polyester from the
fabric stores.  It is light weight and easy to wet out.  Don't get
"acetate", it looks the same but the epoxy eats it up.  I think you can
beat the fabric store prices by ordering peel ply from Northern
Fiberglass Sales.  I have never ordered from them but their price was a
lot lower than the fabric stores around me.  I think I'm paying about
$3.00/yard.  Also, try to get a plain weave because the stretch-fabic
weaves don't peel off as nicely.
    I use the peel ply on about everything to aide finishing.

	Per the recent reference to Northern Fiberglass..... yes they are a
great source.  When I bought from them they quizzed me about my intended
use.  They then knew exactly what I wanted.  I got a partial bolt for the
same unit price I was paying for suspect fabric at a fabric store.  They
were great and I believe they can mailorder.  They are in the Portsmouth,
New Hampshire area.

Builders,
Early in the game we learned that various fabrics sold in fabric stores
work well as peel ply, and can sometimes be purchased at quite a low price.
We learned that hard-weave (not fuzzy or stretch weaves) nylon, polyester
and dacron work well. Watch out for cotton and rayon. I would examine the
roll ends table where things were reduced for clearance. I was able to
purchase several rolls of nylon like is used in ski jackets for $.45 per
yard, and later wished I had bought the entire table. I learned it is best
to take a sample home, use it on a wet layup, and peel it off after cure,
before buying a whole bunch. I found some that were completely unuseable. I
also became friends with the people who made "envelopes" of Dacron to cover
the wings of fabric covered airplanes. They ended up with huge boxes of
scraps which they threw away. All I had to do was pay the packaging and
shipping costs and they would send me as much as I wanted. I learned it was
necessary to iron the material flat to prevent the wrinkles transferring to
the layups.
