Take a three-eighths inch (2.3 cm) thick metal
plate and cut it to the size shown in the drawing, about three by six
(7.5 x 15.2). First cut the bolt holes. These holes are a half inch (1.2
cm) by an inch-and-a-half (3.8 cm) so that the iron can be adjusted back
and forth to compensate for one ox stronger than the other. This gives a
little additional leverage to the weaker ox so that he can pull on the
load evenly.

After these holes are made, then you cut two round
holes for the rod that will hold the two rings. This should be at least
five-eighths inch (1.6 cm) soft rod. After the holes are cut, then you
bend the rod so that it fits right into the two holes, all the way
through. The rod ends should stick out the other side of the plate.
Before you insert the rod into the holes, you have
to make the rings. As you see in the drawing, there are two different
size rings. The smaller one is heavier, made out of a five-eighths inch
(1.6 cm) rod and is used for the chain that you use to pull your loads.
The thicker ring for the chain fits through the thinner ring. The larger
ring can be half inch (1.2 cm) rod since it doesn't take very much
stress. (Remember, the larger ring is thinner and the smaller ring is
thicker.)
After putting the two rings onto the bent rod,
insert the bent rod into the two holes in the plate and weld them. Weld
on both sides of the plate all around the rod and then whatever is
sticking out beyond the weld on the bottom of the plate, cut it off and
grind it smooth.
When you mount the irons on the yoke you will have
to make some little grooves in the wood for the stubs of the five
eighths inch (1.6 cm) rod which are sticking out of the bottom of the
plate. This is so that the plate can fit flush with the yoke and also
slide back and forth when you want to adjust it. The irons get bolted
onto the yoke with one half inch (1.2 cm) carriage bolts. The irons
should be very well made with indestructible welds. When the oxen are
pulling very hard on a load, if the irons give way and break, there can
be dangerous consequences.
