Should have left well enough alone. Made a ipe bow backed with bamboo, 65" nock groove to nock groove. Was pulling 54@28" and tillered for 3 under. Decided to reduce weight to 45@28" if possible. Ran into a problem on tiller. When l got it straighened out, bow was at 36@28". Anyone have a swag on how much to shorten it to get to about 45@28". Would it be possible to glue a taper on the belly and re- tiller? Thanks, Don
