I use a scrap of 4x4, about 6" long or so... I raise the arm and put the 4x4 under it toward the back to hold the arm at that height... to make mine sl. more useful, I took it to the drill press and drilled a hole to precisely accept the removable end of the blade holding screw, ie. the part that gets burnished shiny and lets blades slip out too easily. I can then touch that shiny surface to a sanding disc or belt to make a new flat, roughened surface, perpendicular to its shank, for better blade grip.
