You sure can use a drill. I used a 4' pc of 2x6 for the base. Put 1' pc of 2x4 on one end and mount the drill to it with large hose clamps, like the kind used for duct work. A couple of pc's of all thread some more scrap wood that is drilled for the rods and some roller blade wheels or sliding door wheels, the kind that come on a bracket. Use some nuts to adjust the height of the jig so that it is in line with your drill chuck. Make sure you put a good bit of masking tape on the blank where the wheels come in contact with it. Put a 6" 3/8 dowel in the chuck, turn on the drill and shap the dowel so it fits in the blank, tape it on (duct tape works well here) Now you're ready to shape that grip.
