Absolutely right if the columns get put in after the core is laid up - if you put columns in after the core gets laid up then you need to make sure not to drill through the exterior skin and also make them smaller in OD than your washers on the inside. If you are going down that route you can also use fiberglass washers or plate glassed in on the inside (if there is enough room) and still keep larger diameter columns. You would still need the metal washers though.
