I have done vacuum bagging of plywood fins but before they were installed. I used Teflon peel ply which is expensive but works really well. I did a sandwich of plywood fiberglass peel ply and bleeder cloth. I’ve used Fiberglast but there are other options. <br><br>Bob<br><div class="gmail_quote"><div dir="ltr">On Sun, Sep 23, 2018 at 1:38 PM David Bloom <<a href="mailto:dwskb@att.net">dwskb@att.net</a>> wrote:<br></div><blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex">Forgot to mention if you are not familiar with them go to The Composites Store for much info and materials on what you are doing.<br>

I thought you were using plywood? Recall my<br>
fins vibrated into shreds due to large size. Are you<br>
reinforcing plywood with carbon fiber or are the fins<br>
fiberglass? How many layers and are you doing anything<br>
special to reduce vibration?<br>

Doing<br>
a non-bagged (probably just<br>
weighted) fin, CF, tip to<br>
tip job on my 5.5" Black Brant.. and<br>
need some<br>
supplies. I'm using West Systems and a<br>
course weave CF<br>
(not for looks.. it's just what I<br>
have). <br>
<br>
Also.. I would love to hear discussion<br>
on preferences of the<br>
various types of peel ply. The nylon<br>
kind,<br>
plastic/rayon/paper kinds, or the kind<br>
the red lines in<br>
it..<br>
<br>
Do<br>
you use bleeder cloth (for catching<br>
excess epoxy)?<br>
