A bottom feeder here. I thought the video was a little miss leading, in that it didn't account for all the costs. Should include the cost of the switch, and power supply, not everyone has those just lying around. Having said that, I don't think I would want to operate it with a foot switch. Maybe a simple toggle switch. one foot switch under my saw at a time is enough. I would want mine stationary mounted that would move with the saw, My saw is on casters and gets moved, I don't think I would like to have to "zero" in the cross hairs each time I go to scroll.. I think I could figure out a way to mount it with the saw. However, I would like to try it sometime. I am a low down, bottom feeder, and always will be on my Hegner, but I would like to be able to do it either way on my Seyco saw. Just like I like to be able to scroll with flat blades and those "nasty" spiral blades.
I have yet to master top feeding a 3/0 or 2/0 size blade, through a hole drilled with a #70 bit, trough the work piece, through a zero clearance insert to the bottom clamp. Guess I am just not coordinated enough to accomplish that.
