attached corrugated cardboard to the sides with duct tape. A plywood shelf was screwed to the bottom of the fan, then the fillers were held in place with a bungee cord.

Use the workshop vacuum to remove the accumulation of dust that builds up on the filters. When doing a lot of sanding, the fillers should be vacuumed every hour or so. If a lot of sawdust is allowed to accumulate 011 the filters, it will restrict airflow, which defeats the purpose of the fan drawing the dusi away from you and may result in the fan motor overheating. The filters should be replaced regularly depending upon use.

A dust collection system with a 4" intake hose, positioned as close as practical to ihe sanding drum, is also an efficient arrangement for edge sanding and contouring.

Pattern for 4"-Dia. intake hose

Scale: 1 box = 1/2"

1 used a piece of wire to hold the intake hose to the drill press column near the sanding drum, ff you decide to use a system like this. I highly recommend taking the lime to make a guard for the end of the iniake hose. Here's why. When the dust collector was delivered, I was anxious to try it out. The hose was connected to the drill press as described above, and the machine was turned on. 1 grabbed a piece of the project I was contouring and started sanding it . . . for about 30 seconds. 1 lost my grip on the piece, and it shot down the intake hose like a bullet hitting a bull's-eye, dead center, making the kind of noise you don't like to hear coming out of a new tool. Figuring the impeller was wrecked, I shut it off, unplugged it, and took it apart. Well, the impeller was fine, bul my perfectly filling intarsia pait was mutilated, having several chunks missing from it. My next project was making a guard for the end of the hose.

A piece of 1/2." mesh hardware cloth was cut as shown. The long ends were bent over to grip the end of the hose with no need for additional fasteners. Voila! No more eaten iniarsia parts!
