After procrastinating about 10 years, I am finally building my cutoff bench fo rmy Makita 12" SCMS. Soon, I'll need to install a long fence and stop block system. I was planning on buying the Kreg system.

But I ran across this guy's system at lumberjocks:

Basically, instead of a fixed fence on the bench, he inlays a long T-track where the fence would go. Then, he has a little sliding block that serves as a fence, and incorporates a flip-down stop for repeated cuts.

The big advantage is that the bench is flat and doesn't have a permanently mounted fence, in case you need that huge flat workbench area for some project.

So, I wonder if a short movable "fence" would work just as well as a long fixed fence. One advantage I can see is when trimming warped stock. A long fixed fence could be a disadvantage in this case.

Opinions?
