This had been bothering me since the beginning of this discussion.  We use
wide scrapers to cut burr comb off the top bars in the extracting plant and
any great height variation would be a real pain.  I went over to the hired
man's and brought home a brand new Pierco one-piecer (we obviously need a
few more warm days as I have to much time on my hands yet).  Our equipment
has Dadant, F.W. Jones, Mahurangi, Western Bee, Glorybee, a whole lot of
others that are no longer around, as well as some home made frames.  Here's
what I found on the opposite side of the continent from Lloyd.

All frames (including the Pierco) hung in the super to within a flea's hair
of the same height of each other.

Interestingly,  the thickness of the top bar was quite different here than
Lloyd's findings.  The Pierco top bar is only 1/4" thick.  Our wooden
topbars ranged from 9/16" to 3/4" thick.; a full 1/2'' more in most cases.
Width was virtually the same.

Just for infromation
