premise - adding tail weight to any arrow will increase the arrow's spine.using the 'internal point weight nail footing jig', adding some weight to the nock of the shaft before tapering for a plastic glue-on nock will increase the spine of the finished arrow. the nail jig's smallest size is for 11/32" shafts, but adding a few wraps of masking tape to the nock area of the shaft, or perhaps making a collet outta aluminum can, will allow the jig to center itself on the shaft end so that the 9/64" hole can be drilled down a goodly 2" (or more).
i like the idea of 'frugal woodies', just ordered out a hundred of those woodcrafter birch dowels. using canada goose feathers and self nocks will further cut the cost down by a huge margin, and .32 caliber brass shell points plus a nail footing will make for some neato roving arras. post and pics to follow. ah, the fun never stops - eh, mike? :D
