I say this because I'm here alone and @ 80/85lbs my 2Bs are not easy to man handle. Now I know I can easily lever them to gently flip over that's no problem. I already know I'll have to move my console to place the things and since that's on sliders that's ok also. My worry is centering the base plates once the spikes are screwed in and leveled.I have this idea and see if you agree w/ this or have a better way, and there is only me so keep that in mind. Once screwed in before flipping them make a template of cardboard by piercing it and then make the holes big enoungh for a sharpie to mark the spots on the floor.Then place the felt pads on the bases then centered on the dots.I already taped off my leading edge line so at the very least I have a reference point. Make sense?
