Nomex Sources

[Gray E Fowler]

You can make your own by precuring fiberglass skins on a waxed or mold 
released glass pane. Then join the honeycomb to the skins with a small 
amount of epoxy.  A thin layer of the probond urethane would be excellent 
as it is lightweight and will form a bond fillet on the honeycomb.
One problem with this process is that it does not look as pretty as using 
clear epoxy, it is just stronger. Considering that 90% of the people 
(opinion) use the honeycomb "A" sandwich for the "cool" appeal using 
probond may defeat that reason to have it.

So, how is the honeycomb joined to the skin? Ive
always wondered this, figure adhesive is involved, but
figure someone here can explain the technique.....
