A crosscut sled seriously increases a tablesaw’s versatility. Trimming cabinet doors and drawers, mitering small pieces, and making wide crosscuts for items like shelving are all made safer and easier with a crosscut sled.
The sled I describe here was made to fit a cabinet-style tablesaw, but it can be duplicated in different sizes. The secret to making an accurate, smooth-sliding sled is to build both halves of the base separately, then use the front and back fences to join them together.
I used birch plywood for the runners and fence components because it’s inexpensive and readily available, but any 3/4-in.-thick hardwood plywood will work. I made the base out of regular medium-density fiberboard (MDF), but if you’re going to use the sled on a job site, you might want to use water-resistant MDF.
