Homemade Drum Shells ?

Hey Guys ! First i'd like to excuse my average english, I'm a french guy (QC,Canada) but i'll do my best. I'm looking to start a project with my oldest son, building a drum set from scratch ! We both have our own drum sets to play on but he asked me about building one for fun and it seems like a pretty damn good project !! I was wondering if any members here did it before and, if so, i'd like some tips on witch materials to use. I tought about using either : wood but since wood ain't too flexible and dont own many wood crafting tools (I'm pretty much a metal guy and my garage is pretty much filled with welding machines,Pipe bender,sheet bender,metal saws and stuff mostly used for car custom fabrications) & I always hated working with wood for some reason lol, PVC (large pipes cuts), Acrylic (bend it), Plexiglass (seems like pain in the a$$), aluminium (My favorite option so far but have concerns about sounding too ''echo''. Any other ideas ? Any opinions ? I Don't completely remove wood from the list if you guys can guide me.

thanks in advance!!

Chris
