Thread: Work Zone Grinder Fix

About 12 months or more ago I purchased an Work Zone variable speed 4" grinder which will take a 5" grinder disc . However its sat idle on the shelf and in the box since then.

The arbor which should hold the cutting or, grinding disc in place and centred was to small and the tab washer large even for the Adli Diamond cutting disc's I bought at the same time.
I could not find disc's to suit either. The arbor washer was stepped approx 1 mm I didn't measure that at all.

I mic'd everything up the disc's I have, all measured approx 16.18mm or .637" except the Diamond Cut off discs they were 20.03 mm or .7885".

The Arbor washer measured 22.20 mm or .875" a difference of 6.02 mm or .238" thats a tad over 15/64". When measuring 16.34mm the finished diameter and fitting the disc which sat snug.

Set up on the lathe working this close to the jaws I don't mind saying I was uncomfortable with the clearance of the tool to chuck jaws. I checked everything at least six times turning the chuck by hand, moving the top slide and cross slide to make sure they would not hit each other.

Having seen pro fitters turners and engineers shave thou off washer this way I new it could be done either way

The safest way to have done this would have been turn up an arbor to mount the washer onto giving enough clearance.

Now that is a small clearance to the chuck! Might try and get that close next time I'm turning a bowl
