i have some cane that was sent , and the arrows i made were beautiful. i didnt reinforce the shaft itself , as much as i just wrapped the nock. one of the arrows actually split while i was drilling the nock , and after the wrap , it shoots just the same.
i also do like 4est , and use dowels. my bows are mostly <45# , so i have mostly 5/16 , but a couple 3/8 logs. i havent spined any of them , and they all have nutters on them , and craft feathers , but they work. at least on cardboard...
im in the market myself for some new shafts , cause the lauan ones have been shot into cement too many times and have shortened considerably.
4est , i have been looking for an easy spiner , and that is perfect! i was considering the water in a jar idea , but didnt know how to make the rest of it.
good luck on yer arra's , keep us posted...
