Overhead routers are large machines that twist router pieces at high speed. The router bit remains stationary while the woodworker lowers or raises the table under it for the most recent DIY job around your house. The router and the drill press have almost the exact same configuration, but the router runs at a greater rate of speed. By speeding up the drill press, you can use it as an overhead modem. Most drill press machines have alternate belt configurations that allow them to run faster, enabling you to utilize them within an overhead router for some applications.
Unplug the drill presson. Loosen a huge knob on top of the drill press housing. It should face you. There might be two levers on both sides of the housing. If the drill press has those, flip them up.
Catch the oval shaped casing and lift it off the top of the drill press. It might be hinged in back or on either side; when that is the case, then just tilt it all of the way to expose the belt and pulleys.
Transfer the belt up into the highest pulley. There will be two sets of pulleys with a belt running between them. There will be four or five pulleys on every pair stacked on top of each other. Typical drill press machines operate on the most rapid speed. Gently turn the brakes as you pull the belt up with your hands, 1 pulley at a time on both sides until the belt runs between the 2 pulleys on top of the stack.
Close the cover and lock it down. Tighten the knob. Install a 3/8-inch bullnose router bit with bearing to the drill bit chuck and twist it. Put a piece of 3/4-inch hardwood onto the drill press table. Raise the table before the curve at the router centers around the border of the hardwood.
Plug from the drill press and turn it on. Slide the hardwood across the spinning router to conduct a bullnose edge on the hardwood.
