Yes but since I don't plan on boiling my airplane why should I worryabout a boil test, I doubt if any epoxy glues will pass a boil test howeverthey are the first choice of many of the old school boat builders,sail boatspowered run about etc. The point is no one glue is perfect, each has it'sstrengths and weakness'. The marine epoxy I use is Raka Epoxy you canfind it one the net, one of the advantages is it'll gap fill like crazy andtheglue in the joint is stronger than the wood itself, The advantage with theTiteBond is that ventilation and rubber gloves is not needed but neitherof these glues will pass a boil test. The birch ply soaks the epoxy up andsometimes traces are seen coming through the other side of the 1/16ply. Also epoxy doesn't need the clamping pressures other glues need!I do however plan on painting my wings white as with any epoxy planeto keep temperatures down as much as possible.----- Original Message -----________________________________________________________________________________

Yes there are four different polyurethane glues tested in one of the experimenters, there doesn't seem to be any thing wrongwith the glue, however it doesn't quite stand up to resorcinol in thesetest, just call the EAA and order the issue with the test comparison.Also don't repeat me on this but I think Roger Mann is usingthis type glue in his ultra light (polyurethane no brand name) designs suchas the ultra Piet.I choose epoxy because a fellow EAA member uses it andI'm impressed with his own mixed breed design.

>The test for waterproofness in glue is to BOIL it water.>>How about making a plywood floats with TB II and landing in "sleep" volcanolake?That will be a real boiling test
(Couldnt stop this one)I did boil (for 5 minutes) a piece 2 years ago let it cool, it was stillbonded, but pulling hard it did unglue, but I will never boil my plane,would'nt even dare to live it outside in a rainy day.... We love them somuch to be that cruel...SaludosGary Gower________________________________________________________________________________

Russell,Have you researched the Titebond Polyurethane glue which is listed as beingwaterproof? You can go to their website and find some info on it - but it doesn'tsay how it compares to Titebond II strengthwise. It does claim, however, that itis "twice as thick as other polyurethanes" and is "unaffected by finishes." Goodluck on your Piet.Jim________________________________________________________________________________

Casein glue was used for years and has worked well in most applications.It is however made from dairy products and is suseptible under extremeconditions to being eaten by microbes. During WW II, a DeHavilandMosquito or two fell apart in the hot and very humid jungles of Borneobecause the glue had been eaten away. This is why resorcinal glue wasdeveloped. There are much better glues than casein out there, but here inNorth America there should be no difficulties with its service life undernormal conditions.John Langston writes:>> I think Allen Rudoff's plane is put together with>>casein glue.

Walt- I was skeptical about the use of this glue also untilrecently a local industrial arts teacher built up his laminatedFly Baby wood gear, but first testing pieces glued up aftersoaking them in water for a week. (this is without varnish too)His physical testing (vise and hammer) proved the glue to holdperfectly with the wood breaking first as we like to see. ________________________________________________________________________________
