Just going to add a link to the original discussion. I will be posting build logs to this thread when I get to it, to try to keep the information in one place.
The bottom layer is 1/4" HDPE. It’s a low-friction plastic that I’ve secured to the bottom face of the sled. Without it, the plywood would catch and drag a little as it moved across the workpiece. It’s not entirely necessary, but it helps. I haven’t really detailed that part too well so I can see the confusion.
I haven’t weighed out the parts yet, so I’m not entirely sure what the final weight will be. I use these 1 1/2" x 1/2" steel bars to weigh down my sled, and plan on swapping them over to the new sled once it’s built.
