I have used a sled on all the table saws I have had in the past. However, after upgrading to a Grizzly 1023SL from the old Craftsman saws that I have had, I would like to make a high quality, accurate sled. I am just curious what materials people have used in their sleds. In the past I have just used 1/2" AC plywood, KD Fir 2x4's for rails and oak runners. They stayed "reasonably" accurate for many years , but I know there are better materials to use today. I also think my new saw deserves better. My shop is unheated, so stability is an issue for the materials I use. So... what have do you use to construct your sleds?
Thanks,
Greg
