I tend to do a lot of hand planing in my shop. Using bench dogs is the go-to method I prefer for holding a workpiece to my bench. But recently, I needed to plane a board that was too narrow to span two adjacent bench dogs. So I came up with this planing stop using an extra piece of T-track and some dowels.
The T-track can be just about any length, as long as it is longer than the spacing between two dog holes on your workbench. The posts are cut from a piece of 3⁄4"-dia. dowel. I made each of mine 3"-long. I then drilled a through hole in each dowel at the drill press. A 31⁄2"-long, 1⁄4" hex head bolt slides into the track. The dowel is held on with a washer and nut. The dowels are easily adjusted to fit in the dog holes on your bench.
