The caption of the diagram says that's a butt joint,
and it looks like a butt joint to me.  Let's face it,
the terminology of woodworking varies just as much
as terminology in beekeeping.

A "rabbet" is any grove in board.  A common example
is the grove cut in the top of a super upon which the
frames rest (confusingly called a "rebate" by some).

What I was speaking of is a pair of interlocking groves,
running along the entire edge of the boards, one in each
board.  I know that Brushy Mountain Bee Farm (of NC, USA)
sells (or did sell) them.

Proof that the type of joint used really does not matter.

A very good point there.

Please, don't gloat.   :)

Cannot? They choose not to export. Canadian firms can
export all the wood they want, any time they want.

> due to the softwood lumber dispute.

Dispute?  There's no dispute.  There may be some
sputtering and posturing still going on up there,
but a "dispute" would require some disagreement
over facts.  To date, Canada has challenged no facts.

Canada was dumping wood, just like the Chinese were
dumping honey.  A 19% government subsidy is hard to
hide, and harder to explain.  The International Trade
Commission ruling on the matter was not disputed by
Canada at all, which indicates that Canada cannot
argue with the facts.

As I recall, Canada ran crying to the WTO about "unfair
duties".  Not the sort of good sportsmanship shown by
Canada in the curling finals.

Actually, the lumber thing is nothing more than tit-for-tat
retaliation against Canada for banning US queens and packages.  :)

hehehe
