I prefer to wire my frames, rather than use pre wired
foundation, particularly as I often use starter strips instead of
full sheets and I also use some foundation that is
cut on the diagonal. And I have recently
been conducting experiments with foundation starters of different
cell sizings in order to
understand the sizings that I am including in the
special testing foundation
that I am developing.
The dimensions for drilling the holes in B.S. frames are
given in the 'drawings' link above left.
I use 1.5 mm holes in the side bars and I use two in a
British Standard shallow frame and four in a B.S. deep one. The jig
described here is suitable for both lengths of frame side and will
take any form (Hoffman, Manley or parallel).
The basis for this jig is a heavy gauge steel plate 3 mm
thick (10 SWG) that originated from some scrap electrical equipment.
The piece was chosen because it had a portion bent at right angles at
Shaped wooden parts are fixed to the plate to locate the
ends of the bars and the drilling is done using a hand held battery
electric drill (pistol drill). The parts that locate the bottom ends
of the bars were cut from a standard 'one piece' 28 mm wide frame
The inset shows a shallow side bar on position and having
been drilled from the other side. The drilling needs to be done with
the drill held perpendicular to the metal backing plate as it is easy
to skew the drill, especially as the holes wear with use. I have
drilled thousands of holes with my jig and it is now showing wear
around the holes, if this gets much worse I will add a thick steel
block to the backing plate that has a set of freshly marked out and
tightly dimensioned holes.
