Help please!!!!! I am trying to carve a 24" X 14" cutting board. I have mounted the board into a sled that reads 24.885 when under the rollers is selected and 13.735 when I select no to the stay under rollers option. However shenever I select measure board and then length, my sled measures 31.796. I first tried making my sled out of MDF with duct tape on the bottom but after ten attempts and getting the same readout as above I switched to a baltic birch plywood sled without and even with tape. I am so frustrated that I am getting rather splintered! Any ideas?
