This crosscut sled is super accurate. I made it a while back and have been using it for a couple years now. It has two T-track slots, one on either side of the blade to hold down the pieces. There are two handles on the back which help to keep hands away from the blade. The rear block is super thick to help cover the blade as it exits the workpiece.
The second picture shows the extendable stop block which allows me to cut pieces which are longer than my sled is wide. The threaded rod and angle iron nest inside the fence and lock in place with a thumbwheel.
The fence attaches to the sled with two bolts and can be further secured with screws. On the right side of the fence is the fine adjustment mechanism which is of my own design. The third picture is a close up of the mechanism. I tried making a sketchup drawing of how it works, but I couldn’t put it together. The octagon shaped wheel has two threaded inserts, on one side is a 1/4”-20 insert and the other side has a 5/16”-18 insert.
As the wheel is turned, it pulls in the one side and pushes out the other side. Because the movement between the two sides is unequal, for every 18 revolutions of the wheel, the fence moves 1/10”. For those of you doing the math, one revolution is 5 thousands of an inch.
I used the fine adjustment wheel to dial in the fence, then secured the bolts to lock it in.
