6v6 Posted March 12, 2014 Posted March 12, 2014 [quote name='LawrenceH' timestamp='1394577637' post='2393038'] I've found lightweight poplar fine with both butt and dado joints, glued and screwed, but it was essentially void free. Stuff with large voids in is problematic for finishing and I wouldn't trust it to behave structurally/sonically, I used some horrible far-eastern stuff for a prototype and it was a pain.

Maybe I'll try some poplar ply next time if I can find some. Quote
