Hey guys, i have a quick question to all the guru's. When i am cutting my segments how do i know the angle on them is correct without cutting a bunch to see if the circle closes up tight. I have a digital protractor and find that my jig is set up to within a tenth of a degree and i am using positive stops for length control. When i get twelve cut i glue half and half with a dowel in between the two halves to take out some of the error. When it's time to glue the two halves they are what i would consider horribly off. when i cut enough off to get the angle right now i have an ellipse. I am being as precise as i can and still no luck. now for the question how do i figure if the angle on the jig is too small or too long with out wasting a bunch of segments. Sorry for the rambling just a little frustrated. It should not be this difficult. Thanks in advance for the info you guys rock.
