Hi gang, I am a little confused by this term "Riser", is it an
Americanism or just a technical term I have not come across before. Could
someone explain what a Riser does, where it fits etc.
Thanks all

It increases the cutting depth of the saw by raising the upper wheel.

14" saw, it's normally a 6" "rise" over the table.

One assumes it comes from the same root concept as those old rise and run
references used in staircases and landings.
