If you're changing over from Langstroth hives to Warre hives, you're stuck with a conundrum --- should you buy all new equipment, or can those Langstroth boxes be cut down and turned into Warre hives?  I decided to give the latter a try since I was one Warre box short of having equipment on hand for our new package of bees.

We actually have the parts for multiple Langstroth boxes that were never even put together, so I decided to use those for my experiment.  Step one was to cut two of these pieces to the length of the Warre hive (13.75 inches) and two pieces to that length minus twice the thickness of the wood (12.25 inches).  If you'd like to avoid my mistake, which produces four bee-worthy holes per box, make the longer sides be the pieces without a rabbet (indentation for the frames to rest on).  The photo above shows what happens if you disregard that advice.

Speaking of the rabbet, Warre hives require a smaller indentation there than Langstroth hives do.  Assuming you're cutting down a Langstroth deep, you have plenty of wiggle room in the depth department, so mark your rabbet to 3/8 of an inch and cut off the extra wood.  While you're at it, cut enough wood off the bottom of each side so that your box is 8.25 inches tall.

Then it's just a matter of screwing the sides together.  Be sure to use pilot holes and three screws per side.  And do try to cut more exactly than I did the first time around (shown above) or your bees will spend masses of time propolizing all the holes.  (I whittled off the longer sides until they matched up, but next time I'll have Mark do the cutting.)

To be honest, this box is just a stop-gap measure since the new Warre hive I've ordered is likely to arrive after our new package of bees does.  And I suspect I'll keep buying most of  the parts for new hives since top bars, screened bottoms, and roofs feel past my skill level.  However, saving $40 per box by cutting down a Langstroth deep that would otherwise be collecting dust in the barn seems like a good deal if it only takes me half an hour to construct --- sounds like a good compromise between my wish to make all of our equipment and the reality that woodworking is far from my strong point.
