I am a bottom feeder (a Carp). It is not the connecting the blade to the to bottom clamp that is the problem for me it if feeding a 3/0 Spiral blade down through #78 hole going against the direction of the teeth, and finding the hole in the table top as you do it, that gives me great difficulty. How ever if you do the type of scrolling that does not require that, top feeding may be easier. I think like everything about scrolling, it is personal preference.
