I stay over in Laser land most of the time but I make small puzzle cubes and thought I would post a picture of my sled.
My goal is to make Very Accurate cubes with which to build my puzzles. With this set up I have very good control over the movement of the fence.
The saw is a 50+ year old Sears belt drive. Works great.
