MITER KEY REINFORCEMENT with HOMEMADE CRADLE

If you make a lot of miter keys for frames and boxes, you might

consider constructing a shop-made cradle. A cradle provides safe and

repeatable results.

TOOLS

Adjustable square

Drill

Countersinking drill bit

and driver

Clamps

1. You’ll need four pieces of

sheet good stock to make the

cradle. The type of sheet good

isn’t critical—MDF or plywood

are both good choices. The

dimensions are also not critical;

shown are two center pieces at

7 x 11" and sides at 8 x 16". Glue

the two center boards together

at a right angle.

2. Pilot-drill and countersink

screws to hold the center

boards together.

TIP

Countersink bits are often

too short to drill the pilot

hole fully into the adjoining piece.

I like to use a separate drill bit to

increase the depth of the pilot hole.
