Wayne,Sounds good to me. Only one question, is the plywood to to be used the 45 deg. lay up or the 90 deg. lay up? And would it matter which one is used?Well, two questions anyway.The type spar you describe should be straight forward tomake. We use T-88 for our glue and I would guess it's apersonal preference what type you choose as they are allexpensive to buy. Speaking only of the West and the T-88,that is.Also, not being familiar with the West, does it have a broadusable temperature range? Just thinking of your latitude.RodgerPiet in progress________________________________________________________________________________

The plywood I'm using is 90 deg. I would think that 45 deg would bebetter for this particular case as the strips are only a bit over 4" wide. The angled veneers would be somewhat longer. You can use differenthardeners to increase the useable temp range of West System, but I just usethe one which is for something like 70 deg F and warmer as it also has alonger pot life. Can only glue outdoors in the summer. Wayne Sippola, Winnipeg ----------
