Hi Roger,

You have already had several good recommendations. Usually the preferred tool 
is either a band saw or a jig saw because of their depth and speed of cut. 
Sighted people might try following a drawn circle then smoothing it off later 
but most would use a stick or bar pivoted at one end and measuring the radius 
from the centre to the outside dimension of the circle for the jig saw or a 
special jig on the band saw.

When I do a circle I usually use the stick/jigsaw method to rough out the 
circle ending the stick short by the distance from the edge of the shoe of the 
saw to the blade, I think an inch and a quarter, I always have to measure 
because I can never remember. I then make another stick suitable to guide a 
router with a straight cutting bit and run it around to refine the cut to a 
very smooth one.

For something thick like maybe a patio table top you won't be able to true it 
up with a router.

Where I don't want a mark on the surface I have both used double sided tape to 
hold a block onto which I pivot my jig but need to fix an offset so the guide 
stick will lay flat on the work and I have also cut a guide circle template out 
of something like thin plywood or preferably something like masonite.

I hope soon to have a belt/disk sander to use to smooth and true the edge 
rather than a second run with a router or you could also form a jig to guide 
the circle around against a oscillating spindle sander.

I have recently discovered a hand held spindle sander something like a router I 
thought might be pretty cool, I think made by Porter Cable. That might work 
well too.

Hope this helps and good luck.

  Subject: [BlindHandyMan] cutting a circle


  Can anyone tell me how to cut a circle out of a sheet of plywood for a table? 
I have all the saws and tools for most things but am still learning from your 
shows how to use them in different ways. 
  I need to make a few different jigs for different shapes and could enjoy 
hearing from you on how to make them. 
  Thanks for your helping advice.
