A good wood rasp and a cabinet scraper for tillering and bicycle tire tube bands for glue up.
I cut the valve out of the tube and cut the tube in half lengthwise for the bands, one or 2 for each limb.
Another tip...drill 2, 1/8" holes side by side in the handle area of the belly and backing and use bamboo skewers as alignment pins to help hold it all together while gluing it up and wrapping with the tubes.Once wrapped you can place the glue up on the form, clamping at the handle, back up and add a little reflex by lifting the tips up on 3" to 4" blocks. I usually add small clamps to the tips too.
