Step 8Using it
The first step to using it is setting the post height. Measure the thickness of the material you'll be cutting a circle in. Adjust the nut on the post so that it sticks out slightly less than the material is thick.
Mark the center of the planned circle, and drill a hole that the threaded rod post will fit in snugly. Set the post at the desired distance from the router bit, and tighten the handle on top to lock it in place. If you are cutting all the way through your material, make sure to hang the portion being cut off the table, and keep rotating the material periodically during the cut to keep from cutting the table. You could also put a sacrificial piece of scrap underneath the material instead.
It's generally safer and easier to cut outer edges of circles in a counter-clockwise direction, and inside edges clockwise.
If you don't want a small hole in the cener of whatever you're cutting, you can use a sacrificial piece on top. Drill a hole in a piece of scrap, and use doublesided tape to secure it to the workpiece with the hole at the center of where you want to cut the circle. Then just increase the depth of cut by the thickness of the sacrificial piece, and cut as usual.
Alternatively, if a hole would be acceptable on the underside, but not on top, you can drill the hole only part way through the material, and cut from the bottom.
Have fun, and be safe!
