Since the bow is laid out symmetrical now, find the exact center of the riser from tip to tip, measure up 2 inches from center and that is the top of handle, "arrow rest". Then measure down 2 inches from center and that's the bottom of the handle. You could cut 1 inch off the bottom limb after finding the center as above. It won't change the reflex too much. However, I cut 1 1/4 off the bottom limb before I do my glue up. Yes you can start rasping in the facets now.
