I had a cut-off sled, but I wasn’t happy with it. it didn’t slide well at all, I wanted a taller rear fence, and I wanted to try to make some t-track to go on it. so, today, I took apart my old one and started planning the new sled. I was able to remove the old runners without breaking them, which is good, and also without ripping apart the decent plywood that was the base, also good. I was able to determine that the left side of the sled was where the poor sliding problem was and I think I solved it by re-mounting the runner. I thing it may have been slightly skewed as I could not see any bulges or cracks in the runner. I re-mounted the runner using the penny trick, weighted down the plywood with a 5-gallon drum of paint, let it sit for about 15 minutes, then screwed the runner to the base using new screw-holes. I am going to have to try to re-attach the two halves of the sled and use the new fence to do it. I do not look forward to this process.
