[RocketsNW] Silk Lay-Ups

Fri Feb 5 09:32:15 PST 2010

Whether or not silk is good at adding strength it (or most any other cloth)
can be very good at providing a good and colorful finish to a rocket.  Look
at the picture Jack Anderson posted!  I've used (Dave Randall too) has used
"Chromaveil <http://www.fibreglast.com/category/Chromaveil> ", available at
Fibreglast, to dress up some rockets.

I used some cloth I bought at "Linens & Things" (before they went out of
business) to make my "Elvis" rocket.  This gave it a black and shiny gold,
almost sequined, "flashy" look.  Something impossible with any kind of
painting.  The only real trick was after doing the initial layup and doing
some very, very light sanding - I then put a finish coat of resin over it.
The result was a very shiny look, but at the cost of some additional weight.

You'll never know until you try it.  Some of the most significant advances

in hobby rocketry have come from some of the seemingly weirdest ideas.
