productive day, took the advice from you all and narrowed it to 1 3/8" wide, got a 72" caul made with 3" of reflex. started heating and clamping it down and came to the conclusion I don't have enough clamps to do the whole bow, only one limb at a time. Hope thats ok? I suppose this way I can only mess up half at a time. Oh well needed an excuse to visit the big box stores any ways. Looks like its clamps for x-mss instead of coal.
