    I have done the FAA "Glue Boil Test" using T-88 .... nothing came apart. An interesting read; From "Construction Notes" Falco Builders Letter."

    I also love T-88 easy to use and reliable. I used it on my first Piet as we ll as my current Piet project. Lately I have been building a boat=2C GLen-L Sea Knight and have used T-88 on all structural parts.

    Some of you may remember Douwe's FIRST Piet, the one hop wonder. I still think it was the best looking Piet built in the last 10 years but I digress. We started repairs on one one wing at Sun N Fun a couple of years ago and discovered that the gussets on the ribs could be popped off with a pen knife with the wood left perfectly intact. Not good. The ribs were assembled with casien glue aka plastic resin. At the time, it was available from AS&S as well as others even though AC 43-13 cautioned against it. Hopefully Douwe himself will chime in on the issues it caused and the effort that went into making RePiet Several years ago, as an experiment, I made test pieces to compare T-88, Resorcinol, and West Systems. The T-88 was mixed by eye, the Resorcinol by weight and the West System by volume. I used Sitka cap strip and Okoume gussets to make a Tee and then slowly applied pressure until something happened. In all cases except one, the wood failed. The single failure was an improperly built Tee. It is my opinion the reason the FAA does not list epoxy as "accepted" or "approved" in 43-13 is because there are so many kinds with wildly differing quality. I further suspect that none of the manufacturers want to go through hoops to get their products recognized and then ride the liability tail for 17 years or whatever it is now. I have a dollar in my pocket that says both T-88 and West Systems could pass whatever mil or astm spec that applies. If anybody knows what specific testing is involved, it might be a useful data point. Dave Read this topic online here: http://forums.matronics.com/viewtopic.php?p=435919#435919

    Apparently Weldwood Plastic resin is not a casine glue. It's a ureaformaldehyde wood glue I may be wrong on this but from what I can tell from a web search and Weldwoods web page, it's not the same stuff. Also plastic resin has a shelf life which a lot of people don't know about, must be applied correctly (a little thick), needs sufficient clamping pressure and can be real messy.
