Winter Slumber is over!

Finally got around to making some work on the LittleJohn!
It was around 17C in the garage, so no excuses. Two things had been making me slow in working on the lathe:
  1. Lost the cross slide angle adjuster pinch bolt - 3/8" by 16tpi Whitworth with a 1/4" square
  2. Uncertain what to do about the Forward/Reverse Switch
No 1) was finally sorted today when I found it! I spent a day in the garage two weeks ago looking for the bolt, and even considered making my own - thanks to the chaps at Raglan Machine Tools Yahoo Group for advice on the size, to no avail.
But today, after further hunting, finally found it.
No 2) Was also resolved today. The Lathe has an angled casting bolted to the motor which holds a forward and reverse switch adjacent to the variator pulley lever, as seen in this picture. Mounted on this was an original roller leaf spring type four pole switch, heavily corroded with broken plastics.
I mentioned below that I bought a nice new forward and reverse switch (here) but this needed a new housing, so I could not decide whether to restore the original switch, which is possibly 40 years old, or to use the new switch in a plastic housing.
Today I decided that this is a tool, so sorry purists, the new switch goes in the gutted housing. I'm keeping all the pieces, so it may be possible to convert back later.
I also spent some time making a new motor connection cover which has the cable gland mounted direct, as I didn't like the motor outlet at the 3 O'clock position as this will bang on the wall.
Next Steps
Do the actual wiring!
