Wouldn't your burnout furnace be built just like a crucible furnace with the bottom open? If so, use a cylindrical cardboard concrete foundation form about 12" dia or so for an inner form and ram the refractory between it and the wall of the steel drum.

Make a lid with an opening in the middle just like a crucible furnace. The inner form will burn away when you fire it up.

I've never made a burnout furnace ( I use an upside down flowerpot ) but I've made a few crucible furnaces this way.
