Thanks all, This is made of Baltic birch plywood.<br><br> I smashed the thumb in the shop a few weeks ago, Not slingshot related. <br><br>I made this slingshot to shoot hammer grip, I normaly shoot ergonomic slingshots. If I try to shoot this slingshot like the ergos it slapps that sore thumb.<img src="http://illiweb.com/fa/i/smiles/icon_eek.gif" alt="Shocked" longdesc="5"> When I let a someone new to slingshots handle my ergos they get all confused.
