My experience with titebond on the doublers for a Primus. On the first one a weight was placed on them and they curled pretty badly. On the second one I got smart and clamped them between two pieces of 3/4 " furniture grade birch plywood with many hundred pounds of pressure. When the clamps came off the next day they went SSppoonnnig and curled just like the first ones. So much for clamps. See "RE: Phil Kraft's " post 80 for several suggestions on glueing doublers. doxilla suggested "laminating epoxy" which sounds like the most forgiving method. Is laminating epoxy the slow setting variety? This problem is one of the reasons that I have been reluctant to start building my KingAltair kit. Some experimenting with pre drying the titebond is certinly in order.
