First bearing recess finished and faced off.
Here is the second end recessed, faced and a PCD marked with a sharp tool. In left top you can see the grub screw hole that holds the casting on the mandrel. Whenever grub screwing to a shaft it pays to file a flat on the shaft so you don't end up with upset metal that would jamb up on the casting making it difficult and damaging to remove the item from the mandrel.
Getting somewhere now. The shaft was machined from a car front strut. It's easy to get under the Chrome but this strut and others I've machined have a fairly deep hardened section, it's not glass hard but hard and tough. I think it's too deep for case hardening, it may be induction hardened to increase rigidity and strength, anyway once a little deeper into it the strut machined quite well but still a bit tough. For ease of assembly there is a slightly reduced section between the two bearing journals. There is a shoulder on the right end of the shaft which will butt up to the bearing inner race.
Here is the left end of the assembly, the bearing in this end is retained by an Aluminium ring. The pulley on this end will have a hub section that will be a close fit through the ring and push up against the inner race of the bearing and as the other end of the shaft has a shoulder, the shaft and bearings will be retained and located.
This is the end that will have the original motor pulley on it, I made it longer in anticipation that I may(possibly,might,in the future???) machine new pulleys to take wider timing belt(toothed belt) and grooves to suit 7M vee belt.
Casting on left is for the vee pulley for the jack shaft, the casting on the right is for the tool head down feed handwheel for the Gingery shaper.
Later that day I machined the pulley and key-wayed it in the lathe. Here it is all fitted up. So far so good, but I will diverge here for a week or so as I want to finish a couple of things for the Gingery shaper tool head/down feed assembly.
Ok so it's now Saturday three weeks later and am ready to lose use of the lathe for a while. Here's a pic of the stock motor and switch box. Shed a tear now as this motor is about to be divorced from the lathe.
Packed, aligned and clamped into position.
Just showing how easily accessable the rear headstock bolts and crosswise adjustment screws will be. Oh I like that!!!
