I've built 2 lemonwood bows and have two older(1930's-40's) lemonwood bows(one a York, the other homemade). The wood is nice to work with but is susceptible to fretting if your tillering is off.
Not much lemonwood around like it used to be. Lemonwood comes from Cuba(and maybe parts of Central America) and since the embargo in the 1960's it's been hard to get. There is still some pre-embargo lemonwood around.
