I just recently made a crosscut sled, and thought I’d go over some of the advantages and disadvantages of owning a crosscut sled. I can’t think of too many disadvantages, except it is another thing to store in my small shop, which doesn’t have a lot of storage space, or any space at all. Of course, that may not be a disadvantage for you! The only other thing is you can’t use the table saw blade guard, but the sled has a lot of safety advantages.
I looked all around online at the different cross cut sleds that people were making. I really liked the Nick Ferry video, his sled really looked awesome, and he explained how to make it really well. I went ahead and purchased his plans as well. You can also check out his plans here: https://nickferry.com/product/table-saw-cross-cut-miter-sled/
