Hi Jack,
Check and see if there are any boat shops in your area. The nation
wide chains carry West Systems epoxies which are pretty high
quality. They also carry fiberglass cloth but I think you'll find it
less expensive if you order it There are several sources for the
materials online, AerpSpace Composites, CST, US Composites to name a
few. I prefer to lay up my molds with epoxy due to it's stability
and how long the molds will last. I prefer tooling resin from ACP
since it's epoxy based and compatible with the resins I use.
When making a mold I a layer of tooling resin followed by a couple
layers of 4 oz then several layers of 6 oz and 10 oz. The amount of
glass depends on how big the mold it. I've never had to use a frame
for my molds and store them with both sides connected to each other
with Clecos. I haven't used a bladder on any of my fuselages yet but
can see advantages to them. My biggest reason for not using one is
the cost of having it made.
I have a tutorial on my website for making molds if you're
interested. Go to http://www.jtmodels.com/molds.htm
Hope this helps,
Jimmy
Where do I get this stuff... anyplace in Albuquerque, Amarillo, Lubbock,
or El Paso? Primarily looking for mold wax, tooling gel, parting agent,
such as PVA or better if you have a recommendation. Also should I use
polyester to make the mold, or epoxy? I'll be using epoxy (MGS) for the
fuselages. How many layers of what weight cloth for the mold? Do you use
a frame to keep it from twisting / warping? Do you use some kind of
bladder inside? I built one once, for a Legionair. It turned out OK, but
sure could've been better.
Thanks in advance...
Jack
