During the days after Xmas 2001 we were able to get a 440V 3-phase supply connected to the lathe in the workshop, to see if
everything worked out OK before we went any further with getting tooling sorted out etc. A lot of cleaning up was done, removing
loads of Brass swarf which kept getting into my skin!
The main turret head after we had cleaned up and deburred all the 6 tooling retaining plungers.
All were stuck and had burred-over
threads. One had a hardened No4 MT insert stuck in the tool hole,
but a steel bar through the centre of the head enabled it to be drifted out without
damage.
Shot of the front cross-slide just after we had reassembled the straightened lead-screw. The casting for the front bearing
of the screw
had been damaged at some time, and a sandwich made up of a piece of steel and part of the old casting to repair
the assembly. The new piece is visible
as a lighter-coloured material adjacent to the end of the slide dovetail
View of the end of the main spindle (2.125" Dia) with the spindle brake drum and backplate removed.
The drum had run loose on the shaft, and
while the shaft itself was only a few thou down on size, the drum was worn to
the point of being wobbly. The flat belt laying underneath is the power feed
belt to the rear saddle. The main drive
belt housing is immediately behind the spindle, the brake lever is just in shot, with the return spring pin right top.
The spindle brake drum. The drum had wobbled to the extent that it had worn a series of grooves in its rear face where it
had rubbed against the
brake shoes. The backplate rim had prevented it from moving too far off centre.
Spindle brake shoe anchor pins and actuator cam. The broken anchor pin
had been gone for some time, judging by the rust on its surfaces.
Spindle brake shoes, soaked in oil and metal fragments from contact with the brake drum.
Spindle brake shoes, this one breaking up. The brass particles are already in the lining material.
Front cross-slide saddle travel stops after cleaning up. Rear saddle drive shaft behind
(cover is hanging out of the left-hand housing as I have pulled
the saddle rearwards as far as it will go)
Stops are adjustable by the stop screws, and also along the length of the shaft.
