I may have missed this if already discussed, but did any of you read the article in August '07 issue of Fine WoodWorking about "How Strong is Your Glue"? Although they were testing wood-to-wood glued joints and not gluing brass tubes into wood, the lowest strength of the 6 types of glues tested was the polyurethane (Gorilla Glue). The complaints about the testing on the forums was whether or not they clamped per manufacturers instructions, but we don't clamp tubes in the blanks either. I was really surprised how badly is held up even though I have had good luck with it for the last year or so, in pens and general use in flatwork also.
Good old Elmer's Carpenter PVA glue was tested as "Best Value" with almost twice the glue strength as poly. Type 1 PVA (the waterproof stuff) was listed as "Best Overall". They also tested slow-set epoxy as a close second strongest but was much more expensive than PVA. CA was not tested because most flat woodworkers never touch the stuff, it is mostly used by turners.
I was surprised at their results. I wonder if Gorilla Glue will continue to advertise with them?
