<DIV>Just curious, where do you guys get the end grain balsa? I can't
imagine you're cutting your own?</DIV>

<DIV><FONT face=Arial>I'll ditto Bob's response on the 1/64 over
1/4" endgrain. More surface area there to glue to fuse. I use a lt.

<TD vAlign=top>I have had very good results with a firewall made of
1/64" plywood laminated on both sides of 1/4" end-grain balsa using
polyurethane glue. Lightly spray water on the balsa, smear the
poly glue on the balsa and a light, even coat of glue on the
plywood. Press everything together, lay a sheet of wax paper on a
flat surface, set the firewall on the paper, cover with another
sheet of wax paper, and stack a LOT of books on top. The poly glue
will foam and penetrate the plywood, the weight is necessary to keep
the plywood from being pushed away from the balsa by the foaming
glue. The resulting structure is very light, very strong, and
offers a wide gluing surface inside the fuselage.<BR><BR>My setup
uses a Hyde mount, so I glued 3/32" plywood disks approximately 3/4"
diameter to hold the blind nuts on the backside of the fire
wall. Nothing is needed on the front, the Hyde mount has a
large back surface to spread the load.<BR><BR>I have been flying
this in my YS160DZ powered Temptation for 4 seasons now without any
problems.<BR><BR>Bob Kane<BR><A
