It was hard on my legs (and behind) when I was scrolling sitting on my Dewalt bar stool. I put a box under the switch and it worked okay, but I wanted something better.
I built this as a result. I had originally intended on making the angle adjustable, hence the hinges, but after trying out with a few blocks under the top board I found it works at this angle. (It also works fine for my son and wife.)
I took off the protective shield, but you can leave it on.
My only problem is sometimes I back my pressure off the switch thinking it will decrease the speed of the saw. (You know, like a gas pedal!)
The piece of wood at the back is where my heel sits so it doesn't fall off!
