My Ajax mill is going to be my next major project as it needs refurbishing.....
One thing I gave noticed is the Y axis leadscrew thread is not the same as the X......
I suspect the orig has been replaced at some time and looks to be a BSW thread form....
So, I'd like to sort this,so was thinking of using a BSC thread, basically because I can get the taps and dues for 20 tpi.....
Is this the right way of going about this or should I be looking at a different thread form?
