With the aid of my motorized router lift, I can create medium to large circles on the router table easily.
Forget that router trammel or bandsaw circle jig, with this method, you can make circles on your router table with no dust and no fuss. The adjustable pivot point slides in the miter slot and is clearly marked with radius sizes down to a 1/16th of an inch.
This method is safer, cleaner and more accurate than many other methods. If you have a router table with a miter slot, check out this setup!
Update 1/2/2009 - I added a file download to this project that contains a Word Document (tested in version 2003), that will create the printed scale for the jig.
After printing the scale, you will need to adhere the printout to your miter track stick using spray adhesive.
The placement of the scale on the jig is easy to determine -
- In the miter track - locate your pivot point directly under the right edge of the router bit - this position of the pivot is the minimum radius you can cut on your router table.
- Adhere the scale so that the minimum measurement is in line with the end of your miter track (or another reference mark that you create).
- As you move the scale to the right, the pivot point gets farther away from the router bit and the measurement indicated on the scale increases.
