I agree it is not necessary , but if you are dealing with large cones there are a couple of other considerations . I occasionally make S&P shakers from cones in the 2 inch diameter , 4-6 inch long range . I prefer to cast in vertical cylinders rather than horizontally , to save resin . Cones are seldom perfect cylinders of a diameter for which I have something that can be used for a mould . Stabilization hardens the scales enough that it usually becomes possible to grind the cones into a reasonable cylinder on a belt grinder . Wrecks do happen , of course !
However , cones come with a fairly high load of volatile organic compounds , similar to the spruce , pine , fir etc they came from . The vacuum will SLOWLY remove them , but you may still be getting bubbles after a couple days . I draw the line at 24 hours , and live with the results , which can include gluing the odd scale back in , over sanded fingers , and frequently picking them up off the floor . CA is still needed to seal the cut scale surfaces on the final product .
