Aprons

I took the apron off ready to inspect the cross slide. It was saturated with swarf and dirt. The apron was stamped with 72, and the saddle was also stamped with 72. I noticed the dowels that align the apron with the saddle are also a slightly different spacing to the dowels on the saddle from LittleJohn number 1, so it looks like these machines were made before the age of mass machining and part compatability - each one is unique. This means I need to swap the entire Saddle and Apron from machine number 2 to machine number 1. I also need to investigate the LeadScrews, to determine if these are also handed for machine.
The nut that engages with the leadscrew is die cast from zinc alloy. When I first saw it I thought it was ruined, but all it needed was a good clean!
I also investigated the brass nuts on the cross slide - something wierd is happening, as there is an imprint of a large nut, but a small bronze nut is in place. I assume the original leadscrew nut had some method of setting backlash, and may sort something out similar later.
