Roy -- Sassafras isn't particularly "strong". How do you mean "strong" though? Bendable rather than breakable (like Ash vs Balsa)? Resistant to denting (Ipe compared to Aspen)or something else.
I use it to make mountain dulcimers, and it's a lovely wood to work.
Under clear glass it would make pretty laminations, and in thicker pieces a nice riser. But not so much a stickbow. Not much of a modulus of elasticity...
