    Wood magazine June/July 2003 has an article "The Ultimate Bandsaw Table System" the system will cut circles up to 32" diameter on a 14 or 16" bandsaw. The accuracy of your circles depends on the accuracy of your build. I think it can still be downloaded from the Internet Archive if you do a search.

    Its a 12 page article and may still be copyrighted, here's a picture of the jig to help you decide.

    If you make an mdf board to fit you band saw and lock in place then fit 6mm inserts into the mdf board in line with the front of the blade at any intervals you like you can then screw in screw in a short 6mm stud in your case it should exactly 10" away from the nearest side of the blade, this will be the radius of your 20" circle. I have set a series of inserts at regular intervals so I can cut circles of a number of diameters by screwing the 6mm stud into the appropiate insert.
    If you need photos I can take some for you
    Good luck

    I built the jig from wood mag. Works well, although is awkward to clamp on my table. Need to rethink the clamping system.

    search the internet for [adjustable bandsaw circle cutting jig] or just [adjustable bandsaw circle cutting jig] there are many designs from virtually all the wood working magazines. Pinterest has many for example.

    Had a look at the plan, it looks like the jig is mounted on a Delta 14" saw. Don't know what saw you have but if your saw table is thicker or thinner its a simple matter of matching the side rails (part C & D) to the thickness of your table. Changing the Aluminum clamp fasteners to carriage bolts inserted from above with wing nuts to fasten the clamps might make it easier and faster to add or remove the table. If the problem is something different the system looks easy enough to modify to suit your saw.

    See the attached images. I hope this helps. It's much easier than it may look.
