I guess I'm not seeing what your concern is. If you set the stop such that if the vice is fully closed (bar sticks out fully from the back) it doesn't hit the back, then obviously having a larger rock (vice open) would be safe too. I'm just anal lol. In my way of thinking that is. I'm just like why even bother machining the screwfeed.

You could always install a normally closed micro switch through the back wall of the saw so whatever you're talking about (I would need a pic to visualize it)would trip the switch and shut down the saw when it contacted the switch. Not a bad idea.

I had a reworked Hilquist saw that used a microswitch for the auto shutoff. The problem with that saw was if I forgot to shut off the switch on the outside of the saw before opening and pulling the carriage forward for the next cut, instant rock snot baptism. The thing I found interesting about the Hilquist is the moving portion of the vice is to the rear, opposite of most saws with horizontal vices. With it set up that way the position of the auto shutoff stays about the same. The bad part of that design is you need space to the side of the saw in the garage to work the vice.

For those times when you forget to set the auto shutoff and then wander away from the saw... without the machined screw feed (or another mechanism, like the switch), then the vice will happily impact against the rear of the saw. It's basically a safety feature to prevent damage to the saw.
