What you end up with is hardened foam in the joint and the strength of the joint becomes the strength of the foam. Based on what I've heard about Gorilla Glue and other similar products, they have their place but not on aircraft structures.Oscar ZunigaSan Antonio, TXmailto: taildrags(at)hotmail.comwebsite at http://www.flysquirrel.net_________________________________________________________________Talk now to your Hotmail contacts with Windows Live Messenger. ________________________________________________________________________________Date: Mon, 27 Nov 2006 14:59:45 -0800 (PST)

I have used urethane glues extensively, but would never consider them for aircraft. Then again, what do I know? A man I met in NC named John Jeffries built his entire airplane using Titebond III, thestuff you get right off the shelf at Lowes. As far as I know, it is still flying.Ron________________________________________________________________________________Date: Tue, 28 Nov 2006 05:50:17 +0000 (UTC)

Cheers, Jim I realize that, Jim. I was just pointing out another instance where someone used an adhesive that might not be appropriate for aircraft. Harvey then wrote about using the urethane glue, then having to spend hours cleaning up the part after the glue expanded and cured. This is one majorreason I would never even consider it for a Piet. I use it in my sign business when I need to glue and clamp up narrower widths of wood to produce widerboards. For this purpose, it is great because it is strong and easy to sand and clean up the joints (which must be perfect).Ron________________________________________________________________________________

I didn't mean to suggest using it as a structural glue, but it has some great uses in the model world. Holding hinges in the wood, locking ribs onto a trailing edge sheet, etc.----- Original Message -----
