Cleaning up my old lathe

[Mayhem]

The next step was to remove the back gears, which initially was a bit challenging. I finally figured out that the inner shaft had to be removed from the front. To do this, the split bush at the front (which had spilt in two) had to be removed and then the shaft lined up with the casting holes, whilst gently coaxing the shaft with a copper hammer.

Here is a good shot of the eccentric shaft and the split bush
   

With, the back gears removed, the broken teeth could be fixed. There were also a few broken teeth on the bull gear, which I also fixed. Many of the teeth could be repaired simply by brazing the deficit and then filing to shape.

One tooth was missing most of the top and another had lost approximately ¾ of its width (full depth). The former was repaired by welding a steel rod the full length and for the latter I drilled and tapped some holes to suit some steel rod which I then filled in with braze. Again, they were hand finished with a file.
