Well the piece of wood I have the ART13 on is 11" wide, about 1 1/4" thick,
and as long as the hutch (54"), and it doesn't sag in the middle. 2x4 sagged
in the middle with no support. Pressboard is out of the question. This is
the only piece of wood I found strong enough to support almost a 100 lbs of
radio and computer monitor on top shelf of hutch...

so I'm thinking 2X8s, pressure treated.

2X8's? Pressure treated? Tell me your kidding. RM~ :-(




2x4's and 1/2" ply built with common sense would hold as many people as
you
could stand on it. There's nothing wrong with 2x8's if you already have
them,
but it seems a bit of over-engineering otherwise. Still nothing wrong with
them though - to each his own...

Your right about the support. I've built benches that would support a lot of
weight using nothing bigger than 1X's and 3/4 in MDF and plywood but have
used plenty of support, aprox every 18 in. under the top surface. Regardless
of the structure that you choose, I'd skip the pressure treated stuff for
indoor use. They don't recommend it for anything other than out door use
(decks, fences and etc.). You have to use either hot dipped galvanized or
stainless steel fasteners, anything else will rot out the newer pressure
treated stuff. Also some of the chemicals used for treating can be a hazard,
particularly when burned.

Good Luck, Rob Mills

I know too little about wood - I sure do appreciate the tips on the
pressure-treated boards. I won't go with those. Thanks a million!
