I bought a used UniSaw and took most of it apart to clean it up but missed seeing a blade had spun on arbor. I know the blade that came with it was garbage but everything pretty much checked out ok. When I was aligning blade to miter slot I normally setup a dial indicator to check runout. Found nearly .03” on a brand new blade. Uh oh…
Arbor flange had about .0025” runout on the face. ⅝ diameter had less than .0005”. To make a long story short I was able to rig up a little grinder using than flexible shaft attachment for my die grinder. It’s ugly but it worked. Arbor flange face has less than .0003 runout now. Finish is u

gly but it’s accurate.

Drilled through 2 scraps of ¾ plywood and a 2×4 to mount the grinder. I shifted the 2×4 to get wheel perdicular to arbor flange.

Next I clamped a nut to table to act as an adjuster. I figured I couldn’t control the infeed by hand..

Touched off and adjusted angle for square and started grinding.

Nice job. I’ll tuck that idea away, in case I ever spin a blade on mine.

Have your say...
