caster question

You’re correct. 4 of them should hold a capacity of 400lbs. Enjoy the new planer

You’re right – but I prefer a little overkill in terms of capacity. Especially if there’s any room for sag, although that’s probably not a problem for a planer.

Also – consider using a base to lift the working surface up to the same height as your table saw (or other major table object). I find it’s nice to have extra support area around when I need it.
