Product review (4 stars): Pricey, but works on a Grizzly
Bought for use on a Grizzly 10":  i found the LA-120 has M12 x 1.75 female threads while the grizzly base has an 8 x 1.25 male thread...  MSC Industrial has just the threaded insert (i'm sure other shops have as well) - similar to a helicoil that allows this wheel to bolt right on.

Hone on!
