I wouldn't want sandpaper style pads, it would mess up the surface that I most likely want to glue up soonafter.
What's your problem with keeping the domino (and which one) in place for the plunge?
I havn't had any after I realized that I need to hold the 700 exclusively at the handle at the fence when using that to register, should I use the base (with fence retracted) I found that to clamp a reference corner (if possible, else at least an edge) for the machine to be held against is the best plan to keep it from moving while plunging.
