Hey Steve, thanks for putting me back on the list. I was going through withdrawalsfor the last couple of months without it.Just a quick project update, I have the metal control horns formed but notwelded yet. Ribs going together, 20 complete 8 left. I'm using Aerolite for the ribs.Some people ask me "Why are you using Aerolite; the Australian'sbanned it's use?" My response to that is: My airplane will never fly inAustralia!Regards, and thanks again.Greg CardinalMinneapolis________________________________________________________________________________

Hi Greg,Glad I'm not the only "crazy" one. I am using the aerolite glue because ithas had a tried and proven reputation. The hardest thing so far was todecide on which glue to use!. I am taking precautions though, and am verycareful to plan the gluing sequence, and double check the glue and catalystare where they should be. Efforts have been very positive so far. I alsoasked Transport Canada for a ruling on acceptability before starting. Theygave it in writing, so if the regulations up here change, I can avoid theflap.

Ian,Why did you pick aerolite over some of the other adhesives, such as T-88?________________________________________________________________________________

I understand that itgoes by the name Gorrilla Glue in the States. It's a single part glue thatuses the moisture in the air and wood as a catalyst. Of course, using water asa catalyst is different from being water soluable. It's like epoxy when itsets being very hard and it doesn't react to anything we've thrown at it sofar. The neat thing is that the excess glue "bubbles" out from the jointforming a substance like an extremely hard foam that's easily sanded off. Thelocal Transport Canada has endorsed the use of it on homebuilts.Ken________________________________________________________________________________

I did a serious study of Aerolite, Timbertix, T-88, resorcinol etc. Iactually did some tests on all of them, and ruled out resorcinol on highclamping pressure, mess, and lack of gap filling capability. T-88disqualified itself by an oven test where at 150F, the glue softenedsignificantly, and at 175F there was some evidence of glue line failure.The Timbertix was not recommended by a national research foundation(privileged info).That left aerolite with a caution to get the hardener on one side and glueon the other, ie detailed gluing procedures, plus a good reputation onmosquito bombers in the second world war...they go a little faster than thePiet. The glue joints cannot be boiled, but I have no intention of doingthat. I have a nice table in my constructors log that I developed if youwant it. Transport Canada gave the OK to both aerolite and T-88. Hope thishelps. any comments would be appreciated.

Ken, I got into a major testing lab in the US and they do not recommend it(unofficially). It would be nice if this info could get to the EAA, as theyare also cautious. I would have liked to use it, but....
