Entry hall table for a niece: Part 11

Derek Cohen (in Perth, Australia)
The process of attaching of the legs was completed by the addition of two screws in the sliding dovetail base.

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.

The force comes from the splayed and angled legs. They will want to cant outward, and this becomes more so when the three drawers are filled and a vase of flowers is placed on the top of the table.

I thought that it is worth mentioning the screws used and how they were inserted.

The screws are 1" long brass tapered wood screws. The drill bits are also tapered to match. These ones include a countersink and depth stop.

The plan is to drill the hole for the screw through the base and into the case, and then widen the hole in the base. This will permit the base to move with expansion and contraction. In this case 2mm each way.

A wider drill bit (and depth stop) ..

Before inserting a screw, especially brass screws, they are dipped in a little wax. This is wax for lubricating bandsaw blades ...

Here is the widened hole ...

The gap around the screw ...

The second screw is on the other side of the leg. This is positioned about half way between the end screw and the glued toe.
