I've been looking at commercial add on tables for bandsaws and drill
presses with a view to building my own. All the models I have seen so far
are literaly 'add ons'; the new table is mounted directly over the existing
table. The same seems to hold true for plans in magazines. It seems to me
that this adds weight and decreases clearance.

Is there some reason not to remove the existing table and mount the new one
directly to the trunions?

TIA
