 using your table saw rail as a stop block in conjunction with your cross cut sled. Olah Woodworkers, Paul Carlson here, small workshop guy. I built a really simple cross cut sled and today I needed to cut eight pieces precisely 18 inches long. When I checked my sled to the left, which is my preference, I didn't have my 18 inches comes about here. I'm out of rail so I can't set a stop block on a rail. So the option is to use the other side. Well you could use your fence at 18 inches but the problem is if you only use your fence then when you push your workpiece forward it could bind against that fence and you could get some dangerous kickback. So the technique is to put a little block or a piece, a workpiece or something, attached to the fence and so it only goes so far, in this case three inches so when I push my workpiece beyond that nothing is bound up in here. So that's the technique for using your fence. I could set my fence all the way out to here so I literally could have a 35 inch in my case spread and still have a stop block set. So if you're not aware of that technique, highly recommended for safety, small workshop guy, signing off.
