I decided make myself a small basic crosscut sled to use with my table saw. YouTube is filled with videos on how to make a crosscut sled ranging from simple to ones with built-in clamps, adjustable kerf openings and many other features. I won't go over how to build the sled as there are enough videos on YouTube to learn from. I will just share what I learned from building the sled.
Not knowing what features I would really need, I didn't want to spend too much time and money on my first sled. I figure that I just need to build one and try it out to see how I would use it.
Making the runners took most amount of time but that might be because I got lucky when setting the fence to be perpendicular from the blade. I put in a screw on one end of the fence so that I can pivot it. Then I used a woodworking square against the fence and saw blade until it was 90 degrees. I clamped down the fence and was prepared to use the 5-cut method to calibrate it but after I found that I was within .001 and .0005 of an inch I decided that was good enough for me!
