A Perfect Circle Says It's Square

Quick Squaring Trick

Any time you tip your drill press table off of 90° to bore an angled hole, you'll need to square the table to the chuck again when you return to normal drilling. Here's an easy way to check for squareness: install a large-diameter Forstner bit and place a scrap of MDF on the table.

Start the motor and slowly feed the bit into the MDF until the outer rim lightly scores the material. As soon as the cutting starts, raise the bit and check the pattern it leaves in the MDF. A perfect circle indicates your table is properly square to the bit. If there's only a partial circle, the table isn't quite square yet and needs more adjustment.

to hide it. Since the bottom magnet protrudes slightly

from the box, it nests in the lid hole to keep it perfectly aligned. The two magnets are strong enough to hold the lid in place while pivoting.

Squaring your drill press table after drilling an angled hole is easy when you use MDF, a large-diameter Forstner bit — and the shapes you learned in kindergarten.

Pivot Hinge with Magnetic Appeal

Recently, I made a guitar pick box with a pivoting lid. I used a pair of 3/8"-diameter rare earth magnets to create the pivot hinge. To install the magnets, I drilled a hole down through the lid and just far enough into the box edge to seat two-thirds of the thickness of one of the magnets. I glued one magnet into this stopped hole in the box. Then, I inserted the other magnet into the hole in the lid until it mated with the fixed magnet. A dab of glue locked this top magnet in place in the lid, followed by a little mother-of-pearl disk

Rake in the Shavings

Cleaning up a big pile of fluffy or wet shavings after an evening of turning can give your shop broom a real < workout. I find that a small garden rake kept

' ' near the lathe does a better job with less

^ effort, and the tines don't wear out as

( quickly as broom bristles.
