Re: Entry hall table for a niece: Part 11

Derek Cohen (in Perth, Australia)
From the original text,

"Why add screws? The screws are not to prevent the base sliding back (an elongated hole actually encourages this). It is just to prevent the base twisting in, and breaking out of, the socket since there is no glue there to prevent any lateral movement."

Is this concern due to the clearance height? Would "sliders" under the feet alleviate this stress, were the sideboard dragged across the floor?

Brian Boggs provides his kitchen chairs with a leather or PTFE glide.

Jim, the "twisting" I referred to is the leverage placed on the base by the legs, which angle away from the base. Because the legs are very firmly attached to the base, if the legs twist (which is the threat imposed by weight on the table top) they lever the base along with them. While the base is attached with a sliding dovetail, if enough force is applied to it, it could break out sideways (laterally). The screws are to prevent the base twisting over. The base is still free to move along the sliding dovetail (longitudinally), just not free to move laterally.

Regards from Perth
