building a laundry chute
I am looking to construct a laundry chute in our closet. I was originally going to use large diameter pvc pipe but found it prohibitively expensive. I also looked into sheet metal ducting but it didn't seem stable enough and too many places for clothes to snag. So I am going to build it out of 2 x 4's and drywall. It will be about 12" square. I was going to place a side hinged door with a handle on the wall outside the closet for access. And I may or may not place a metal or plastic plate on the ceiling down in the basement attached with spring hinges to cover the hole from the chute. The hole in the ceiling will end up around 2 feet from the wall with the clothes dropping into a large basket sitting on a cart with casters I will also be building.
I was wondering if I could get away with using 1 x 3's instead of the 2 x 4's. Also if anyone could take a look at my proposed plans and comment/advise that would be greatly appreciated!
