How do you clamp to the sled? Do you use a long clamp between the
trailing
edge of the work piece and the fence?

The fingers of my right hand are behind the sled fence. The heel of
my right hand can hold down the workpiece if necessary. My left hand
both pushes the work through the blade and into the sled fence. No
extra clamp required. I am the clamp.

Simpler done than explained.

I got it. (And well explained, btw)
