Glad you made it here jcat. Like Fish said it would not be worthwhile to mess with
dead wood but you can come up with something to work with while that pretty
yew cures. Don't get me wrong, that yew is a fine first step
If you were to purchase a suitable board you could set up your work area and tools
and even build yourself a serviceable bow or two. Would much rather mess up a 6$
board than nice wood and it ain't as much pressure.
