Drawer runner dimensions
I'm building a workbench, and it will have some drawers under the top. These drawers will be able to pull out from either side, so I thought I'd route some dados in the sides of the drawers, and then use a strip up hardwood for a drawer runner. I hope I'm using the term "drawer runner" correctly, as I'm not fully educated in woodworking jargon.
The drawers boxes would be made from 5/8" plywood, and the sides of the carcass that holds the drawers would be 3/4" plywood. I thought, just for alignment and rigidity, that I would made a dado in the carcass, and the runner would fit into it.
So, for maximum strength and longevity, I'm wondering how deep the dados should be in the drawer boxes and carcass, and what the dimensions of the runner should be.
Since the plywood for the drawer boxes is going to be 5/8" thick, I was thinking that the dado would be 1/4" deep. I was also thinking that the dado in the carcass would be 1/4" deep. So my runner would be about 1/2" thick. Is that going to be strong enough?
I don't plan to store really heavy stuff in these drawers, but I'd guess that each drawer should be able to hold a maximum of 30 pounds. A rough estimate of the size of the drawer boxes is 25 inches deep X 18 inches wide X 6 inches high.
