ive cut a few and not been happy with the results, but luckily i have enough wood left over to still use if i can get the joints to my liking. the problem really is with my bandsaw, ive tuned it but it still wanders a bit and i have to really drive it to get a good straight cut. i think i have single fishtail splices down pretty good, and might try one of those but would like to be able to get a good double fishtail or z splice.
