The caster on this base is poorly designed.  It won't lift my Delta 6" jointer because the caster mechanism does not engage when I step on it. It  barley comes in contact with the caster and so provides no leverage to lift the base.  Others have had this problem, while others have had no problem at all, so it's probably hit-or-miss with this product.  I am going to try to modify it so that it's usable.  Don't waste your money.
