My 30 year old sleds did not fit new table saw due to spacing of miter slots. Gave my old sleds to the guy who bought the old saw, and set out to make new sleds. Did some research on best practices in table saw sled construction, and found some great ideas that were new to me, but did not find a single instruction that pulled all the best ideas together. Made this video showing how I made a very precise crosscut sled using the best ideas I could find, plus a couple of my own ideas. If you have any ideas for further improvement please share.
Now researching for design of a precise 45 degree miter sled for picture frames and for frame and panel doors with miter corners. If you have any suggestions please share.
