I’ve been getting a few email requests for a video on how I calculate the error ratio and how to correct and construct a cross cut sled that’s dead on square. I’ve been demonstrating this at the Woodworking shows for the past 5, 6 years and I still get emails asking me about the error ratio calculations. So here it is.
Material List for sled:
Runners: 5/16” x 3/4” x 30”
Base: 1/2” x 34” x 30”
Front Fence: 1-1/2” x 5” x 30”
Rear Fence: 1-1/2” x 5” x 26”
Please check out my website for more videos. http://wnwoodworkingschool.com/

An excellent and very informative video! I favorited it and this is how I’ll build my next sled. He made this a lot simpler than others and the precision really appeals to me. Thanks a lot for taking the time to do this for us!

William, thanks so much for making this available. I can’t wait to get home this evening and double checking my sled. I kinda hope it’s off so I can make a new one per your design!

Thank you so much. I learned so many things from your one video. Your explanations of “whys” and “hows” were very valuable. Thank you for making this video available.

Thanks William! I could have used that a couple weeks ago when I made my sled. Fortunately my design is pretty close to yours and I just need to fine tune it with your method now.
