FP1/Alexander Next Question

[BobS]

I wonder if you can help with my next question. I have started to strip down the my Alexander Toolmaster/FP1 clone, it is in pretty good condition. I am currently puzzled about the purpose of the grub screws on either side of the vertical slides. I have left the allen keys in to help you see what I mean. The screws on each side are different sizes and quite long but I cannot see what they do.
Thanks
Bob

Is there one screw on just one side, or two screws (one on each side)?

There is one screw on each side but they are different diameters

Don’t know “Alexander” so just a guess.
Different size screws points to different application.
Guessing the one on the Operators side is a locking screw that secures the “ Z” axis gib adjusting screw. (Comes in through the bottom of the casting )
No idea on the opposite screw.
Cheers Ross

Both screws were only lightly tightened so I think I will leave them like that. Presumably similar screws are not present on the FP1
