New 90 degree Crosscut sled for AZ Shop

New 90 degree Crosscut sled for AZ ShopI finished my last two projects and had always intended to make a 90 degree crosscut sled for the Arizona shop. Well today I finished. Took 4 half day shop sessions. The old sled that was couple years old when I joined the AZ shop in 2018 is getting loose and cuts between 89 and 91 degrees depending on which side you push from.The sled base is 40” x 22.5” x 0.75” thick Baltic Birch.Front and Back fence are 38.8” x 2.5” with a 12” section centered on the blade 4.25” tall. The front fence is made of 3 layers of 1/2” BB and back fence made of 2 layers of 1/2” BB.Front fence did not glue up dead flat so it went through the jointer and thickness planer. Much better now.Runners are walnut that is quarter sawn. Intended them to be HDPE or hard maple. I cut the maple strips and was not satisfied with the fit. Looked for the HDPE where it was last time but not there. So looked through my sizable shelf of lumber cut offs and found a piece 1.5” x 21” x 1.125” which was going to have to do. This piece of walnut could be cut so the grain was truly vertical in the narrow dimension of the runners.Used a piece of 1/4” x 1 plus inch cherry on the cut off shelf and took four or five passes bumping the fence a smidgen at a time till is just fit in the slots.Spent half a day getting the runners attached and adjusted so the sled slid nicely. You might notice that the runners are not the same length. When tightening one of them got too festive with the drill and I heard “crack” followed that with Oh Sx#t. So got the Japanese saw out and voila all is good.Last picture is the panel for the 5 cut adjustment method (ala William Ng). Cut 5 came out not perfect on the original strip. Cut 5 on strip 2 after adjusting 0.013” came out 0.001” difference in A & B ends over about 14” length.As Mr. Ng said “0.001” is good enough for me”.
