Conversion of a National Nuc to 14x12

[WellAllbee]

Anyone have an idea how this can be achieved?
Does it involve the use of an Eke, similar in principle to the conversion of a National Brood box to 14x12. If so, are there any plans available?
Thanks

If it’s a poly all the suppliers do brood ekes.

If it's a wooden nuc and has a removable floor it's just a case of adding a 90mm eke below the nuc and reattaching the floor. If not it's a case of making an eke with top and bottom rails.

Probably best to make or order new one.
box without top or bottom won't be that hard or expensive

If it's a timber nucleus with a fixed floor it's not too difficult to make an eke to go on the top and then attach it to the mainb body with hive fasteners (one at the front and one at the back). I get mine from simon the beekeeper on ebay:
