if its thick enough you could take a belly split by following a growth ring
if its wide enough
split it and folllow tha longitudial grainr not real unless you cane fllow grain real good by hand and are skilled with a band saw i dont recomend using that to split it
you can ruin wood real quick if you arent real carefull with power tools
ive taken several belly staves from thick pieves of wood like osage
where i live its very very very hard to aquire osage(it doesnt grow here)
so i take all precautions with it as i dont want to waste it
but its your wood,take my advise for what it s worth
pretty much nothing to most folks
