Marchant Dice router no thrust bearings?

This is what I think I would need machined to take the bearing blocks at the drive side. The top pic shows whats there and the bottom shows what I think I need.

As there is not enough material, I would need to chop the current machined end off and weld a new one in to give me the material I need for the new design.

This is how I have machined my ballscrews before as my lathe aint up to the job of machining the hardend casing off. It makes the maching a lot easier anyway and as the welded on blank is oversized when it is turned down in the lathe it brings itself concentric with the screw.



Something like this for the bearing block?

Its a little smaller than the recommended block but I doubt it will matter too much for this router as I am only looking get something in there that will work relative to the limits of the rest of the machine.

That looks like a Myford lathe and with the correct cutting tool will handle machining ballscrews, my little boxford does. But with this job then it wouldn't hurt to anneal the end up to remove hardening.

From the pics of motor with screw then there is a bit screw left with enough room for a nut so just thread the whole lot then grind flat spot for coupler screw, you may have to machine a new coupler or a sleeve.? . . . Sure it could be done easier than welding bits onto screw.!!
