 damn what is all that strange cryptic markings on the sled. maybe egyptian perhaps ? i thought you were in AUS. duckie ? 
I pulled out my rosetta stone copy and it all makes sense now!

I use quite a few different kerfed blades, dados and angles so I needed a different skin for each.  Ticking a box was easier than my illegible hand scribbling.

I wanted to use this for thin and thick kerfs,
but realised I had more combinations, ran out of ducks and knew that not everyone can read duck!

If your first cut is too short... Take the second cut from the longer end... LBD
