I have made a new flange block and pressed in the 6205 bearing.

Purchased this hole saw set from the local Sunday market for $25 bucks and for the outlay it’s surprisingly decent quality. The bearings I’m using are 6205’s (52OD/25ID) and the closest hole saw size in this set is 51mm so after drilling the hole and careful clean-up with my improvised drill press drum sander to achieve a nice press fit into the block using a bench vice.

I have removed the lower shaft from the saw because I’ll need it to mount the new flange onto the wheel – more to come on this.

The saw looks a bit sad with no lower wheel.
