OK - well time to add to this thread.
One of the things that my lathe doesn't have is carriage locks of any description. My lathe has flat ways, with a dovetail on the front edge. There are two large gibbs, one at each end of the saddle, as shown below:
Here is one of the gibbs from when I tore her down. The bolts that hold the wipers (which I have to make) are 5/16" (the ones there were just to test the thread - the real ones would be much shorter).
Basically, I cannot see any way to lock the carriage from the front/top and it looks like I need to go to the rear/top and make a clamp that pulls up on the bar that runs beneath the rear way.
Looking from the top, there is already a hole that passes through the carriage and the bar. I'm not sure what this was for originally, nor do I know what the three smaller holes around it were for either. They have broken fasteners in them. I did wonder if coolant was piped through here?
So - anyone have any thoughts on using this as a carriage lock?
