always better off drilling the hole first and then turning around it. If you were to try to bore the hole after the turning was finished, you would NEVER get it centered.

I squared up my 1 -1 /2" blank and cut it to 8-1 /4" long, founa the center of both ends, and center punched these locations. Doing so makes it easier to position both the drill bit for the next step and the tailstock later on when mounting the blank on the lathe.

I used a brad point drill bit to drill my hole. It is a very accurate bit which will not wander as much as a conventional twist bit. I used a combination sauare to be sure that the stock was perfectly vertical and drilled the hole 3/8" deep. Hint: it's a good idea to drill a hole in a piece of scrap stock to check the fit of your bristle head; they might not all be of uniform diameter.

Be sure that the stock is verti- Check that the bristle bead cal before you drill the hole with fits as it should,

INTRODUCTION

It's been said that "necessity is the mother of invention" and this was certainly the case when I designed the Computer Duster. My computer is located near my shop area and, as such, is subjected to a lot of fine dust. Even though I keep it covered, the fine dust particles filter up under the cover and lodge in all sorts of places where they shouian't. I use the commercially available "canned air" to blast away those loose particles, but some still manage to remain behind. I used to use a small paint brush to help dislodge the more stubborn dust particles until I ran across these basting brush tufts in the Craft Supplies catalog.

There are three sizes available. The largest one, which I use, is 7/8"-Dia. at the base, and the others measure 5/8"-Dia. and 3/4"-Dia. I prefer the larger size because I need the extra bulk to get rid of the fine sawdust. If your computer is housed in a more computer-friendly area, you can probably get away with the smallest of the three. Just reduce the dimensions accordingly when you turn your handle.

I chose kingwood for my handle. It is a member of the rosewood family and turns exceptionally well. Because it is an extremely dense material, it cuts very clean. If your tools are sharp, very little effort is required to sand the turning. Other members of the rosewood family, such as camateo, cocobolo, or tulipwood would be excellent choices as well. I am particularly fond of the camateo!

Any time you have a project that incorporates a hole in the center of the turning, as this one does, you are
