I bought a couple of 700mm blade's for my saw bench last year. And I finally fitted one yesterday the centre bore was 35mm on the new blade's and the hub on my saw was 1 1/2" so I turned the hub down. I only had a 600mm blade on it before this new one slices through wood like butter, and I still have all my fingers.












i pulled the heads off and it was perfect. put it back together, bled the cooling system and ran it for 30 mins with no issues. it however only took me 6 years to get around to figuring out how to shim the heads to the right compression ration
