Some times I just need to know where my carriage is. Took an import 2" travel dial indicator and hack sawed (yep hack sawed) off the mounting flange that was clearly in my way in order to use this indicator as I wanted to. The back was removed for the sawing. Good thing too, the mounting flange was hollow. Filed it smooth and filled the hollow part with epoxy. Made up the clamp from aluminum and a few screws. Clamps to the rear bed of the lathe and is easy to position when the carriage is relocated. Two inches is usually enough travel but it might be nice to obtain a 4 incher!
