Halifax 10" lathe

I don't know if you've used a bearing puller before, but if not you need to apply force to the inner ring only, the one that's on the shaft. If you apply pressure to the outer ring you will damage the bearing.
Sometimes you can make a steel wedge, with a slot in to take the shaft, and drive it in behind the bearing, you may need a packing washer that contacts the inner race only.
