View Full Version : Use CA to Harden Foam?

10-06-2005, 07:49 PM
I need to put in new landing gear blocks (I use hardwood) in my Formosa. The previous ones were epoxied in but one has broken out without an real hard landings. When I feel the foam it seems soft. So I'm wondering if there is some way to make the foam harder before epoxying the blocks back in.

Can (thin?) CA be used to harden the foam? If so , how do you do that?

If not CA, something else?

Maybe some non-epoxy glue that is strong and goes into the foam giving the area more strength?

Get some 1/32 ply and make a short dummy rib maybe two ins. long to bed into a fore and aft slot cut into the wing. Before you glue it in, cut a slot in it that the gear block will fit into it. One ply piece for each end of the gear block. The idea is to spread the load out.

Get some Gorrilla Glue from Home Depot and they will never fall out again. Dont use CA. It will melt the foam unless its the foamsafe oderless stuff.
