Vacuum Hose Bracket.

• The drum sander on my drill press produces lots of dust. To collect the dust, I slip the hose on my shop vacuum into a bracket attached to the column of the drill press, see photo.

Besides keeping the hose from flopping around on the drill press table, the bracket is easy to adjust. So I can put the end of

the hose right where I want it.

The bracket consists of two parts. A keyhole-shaped yoke made from 3/4"-thick stock holds the hose, see drawing. And a metal hose clamp secures the yoke to the column.

These parts are held together with a carriage bolt and wing nut. The bolt passes through a hole in the hose clamp and into another hole in the end of the yoke.

Note: The hole in the clamp is slightly larger than the square shoulder of the bolt. This lets you tilt the yoke to the desired angle without loosening the wing nut.

To provide clearance for the wing nut, there's a rectangular opening in the yoke. And a large hole is sized to accept the hose.

When edge gluing boards, I use scrap blocks to distribute the clamping pressure and avoid denting the edges. But sometimes the blocks fall to the floor before I get the clamps tightened.

To solve the problem, I made a number of U-shaped clamp blocks

that stay right where I put them. The secret is a piece of self-adhesive weatherstrip attached to the "jaws" of each block, see inset.

When you slip the block over the edge of the workpiece, it compresses the weatherstrip, see drawing. This provides just

the right amount of resistance to hold the block in place.

To make the clamp blocks, it's easiest to glue up a long blank. Then just cut the individual clamp blocks to length.
