Hi Paul, I guess you don't recognize me, but I am head of the WNG technical. We have install at least 20 Masons with the Composite Actions at the factory and 70 percent have the Gel CA and we found that the No.10 drill size is best to give the work time before setup of the glue and the viscosity of the glue takes up the gap. The tighter the fit the shorter the work time and that is why some techs have complained about the short work time. Mark
