Need Source for Arbor Shims/Spacers

[Mike Goetzke]

Ideally I need a 5/8" ID x 1-1/4" OD x 0.045" TK spacer for my circular saw.

Thanks,

Mike

McMaster-Carr: 97063A410, .048 thk (close enough?) carbon steel.

97669A215, zinc plated. Or 96853A111, if you want the fancy stainless steel version. Hole tolerance is better on this, and although it's more expensive, you'll only be stuck with 4 extras instead of 24 ;-)

Amana tools makes a very nice set. I don`t remember the price but it has paid for itself. http://www.amanatool.com/dadosets/dado-shims.html
