Will sag be an issue?

That angle iron would do a lot if you install it 'upside down', that is with the vertical web downward. 1.5" x 1/8" of metal over 5 ft is a hell of thing to bend in the vertical position.

(I do metal working as well as woodworking. Real world experience tells me this isn't a bad solution. Would still have a beefy bottom (3/4" ply))


Maybe do 4 pieces.

I did it that way, but 2 pieces. Thinking of putting roller ball on 4x4 wood piece at bottom front. That should prevent any sag, but I’ll have to screw it in from top (not a big deal). Also, shouldn’t prevent easy movement like an extra caster wood.

Actually it isn't, because the extreme fibers are only 1/8" wide.

I made a few videos:

Hope they work, I made the link share-able.

Question, do they not sell 4x8 sheets of one inch thick Fir plywood in the States ?

I’ve never seen any. FWIW. The 3/4” Baltic Birch plywood sheets were heavy enough. Can’t imagine what 1” sheets would weigh.

Seriously thinking of adding a 4x4 small post with one of these wheels mounted to the bottom in the front center of the cabinet. This has got to eliminate sagging, even without one of these in the back. Right?

I built a counter top spanning over the top of washer and dryer. Span is 5' 2" and it is supported on both sides and back. I used 1 1/2" x 1 1/2" x 1/4" angle iron to span the front that is bolted to the front edge of 2 sheets of 3/4" MDF glued together. The front face of the angle iron has a piece of wood attached with screws. I used laminate on top and front face of the approximately 2" finished thickness of the counter. It deflects when I put my 190 lbs on the front edge. Not much but more than I would want on a cabinet.

I also built two 5' cabinets and bolted them together. They are permanently mounted and sitting on a ledger along the back and screwed to the wall studs. I supported the front with adjustable legs at the corners of each cabinet and in the center front of each cabinet. My cabinets did deflect in the center and I used the adjustable legs to keep everything level. If you use adjustable legs like I did for the center, be careful to screw them up so they do not hit anything while moving and make sure cabinet is locked in place before extending them. They are not made for lateral force.

I attached picture of each.

If the cabinet is only occasionally moved then the center supports could be a little short and then shimmed to level after moving. Could also use castors and then shim as necessary after moving.

Or you could make a tee by bolting two angles together and install it as a tee.

I have a 4x8 sheet of 1" MDF leftover from years ago when I built a subwoofer box for my old vehicle. I had to move it recently while organizing my garage and had forgotten how heavy that thing is. I can barely lift it off the ground. I think I ended up sliding it on the floor (smooth concrete, fortunately) and then standing it up into place.

I need to think of a project to use it, but then I'd have to move it again.....
