Topic tags/keywords: question plywood

Hi –
I am making a rolling cabinet to place a work table surface on top of (the Paulk workbench).
I’m doing this as part of practice for future built in bookcases and cabinets for my daughters craft room.

Would 0.5” ply be appropriate/acceptable for the carcass of the cabinet (also for the future bookcases) or should I be moving up to 0.75”?

Everything will be quality plywood (baltic birch or the maple stuff at the BORG from Columbia Forest).

Thanks in advance for the tips!

If it were me…

I’d go 3/4” ... more mass

I bought a sheet of the Columbia Forest maple to do some projects a few weeks back. It’s the first sheet of ply that I purchased from a BORG that did not transform into a potato chip. It remained very flat. I’m a fan.

What Nicky said … I don’t think 1/2” will offer enough structural strength.

What Nicky said +1,000,000

I have found Columbia Forest products to be high quality.

For my rolling shop carts I always use 2 layers on 3/4” for the bottom as well.

Last time I bought ply from my wholesaler, it was from Columbia. This is north of the 49th.

Birch 3/4” I got it home and went to measure the thickness. Darn near had to call 911. It was 3/4 buy tape measure. WTF ??? got the calipers out and it was 3/4. All over.

Great core. Nice faces both sides. I can’t remember the price but it was not bad. No warping.

I will buy it again.

The challenge with half inch isn’t the lack of strength (assuming Baltic), it’s attaching to the thinner edge. Hence the standard remains 3/4.

Kindly,

Lee

I agree with everybody else. I’m not sure what your fastening/joint approach will be, but if it’s pocket screws, you’ll have more luck finding sizes applicable to 3/4” stock locally than you will for 1/2”. At least around here, none of the big-box stores or local stores carry the necessary screws for 1/2”. Plus you’ll gain more thickness for said fasteners and/or glue.

what Lee said – I think 1/2” would be plenty strong enough, but jointing those edges, dadoes, and attaching hardware (slides, drawers, etc) to it is more challenging on 1/2” and is much easier done on 3/4”
