than 1 inch (25.4 mm) (No. 9, No. 10, and No. 11 bar),
the minimum pin diameter should be eight times the
bar size. For No. 14 through No. 18, the pin diameter
should be ten times the diameter of the bar.
To get smooth, sharp bends when bending large
rods, slip a pipe cheater over the rod. This piece of pipe
gives you a better hold on the rod itself and makes the
whole operation smoother. You can heat No. 9 bars and
larger to a cherry red before bending them, but make
sure you do not get them any hotter. If the steel
becomes too hot, it will lose strength, become brittle,
and can even crack.

If you do not want your rod to crack while it is
being bent, bend it gradually, not with a jerk. Also, do
not make your bends too sharp. Bends made on a
bar-bending table or block are usually too sharp, and
the bar is somewhat weakened. Therefore, certain
