The home renovations are nearing an end (for now) and I am making some Victorian style base boards to replace the ones which were torn up during the renovations. More info on the base boards when they are installed. I need to scarf a couple of boards together for the longer walls and miter all the ends. The stock miter gauge worked fine for the smaller pieces but wasn’t up to the task when I tried to cut the ends of the 8’ long 1×10’s; too much torque. A crosscut sled was clearly needed. I need to make both 90 and 45 cuts so the sled won’t be zero clearance. The sled was cut from a quarter sheet of ¾ MDF. I need to replace the runner since MDF isn’t the best material. I’ll have to order some UHMWPE or similar. The fence is doubled up around the blade to provide extra support and a little margin of safety from the blade coming thru the back side. I will likely add a 2×4 or similar to the back to keep my hands away. The sled was glued and tacked with brad nails and reinforced with screws once the glue dried.
