To position the material being formed in the brake,
mark a line on your material that is mid way through a 90 degree bend (the
45 degree line), then place the material so that you see that line when
sighting down the radius head from a bird's eye view. Also known as the
shadow line. This will be easier than it probably sounds.
You do not need to clamp the
material. Once the apron roller (the part that swings up from below) makes
contact with the material being formed, the material will not move on the
Capacity: 6' model with 1/2" radius 72" 16ga, 48" 14ga, 24" 12ga, 4" of

10' model with 3" & 4" diameter tubes: 20 ga full length mild steel capacity.
Choose your length: models are available from 4' to 10'
You get 5 radii: 4 radius tubes + 1 radius head (shown with 1/2" radius head installed)
Tubes are used for radii 1" and larger.
Four tubes are included: 2" tube for 1" radius, 2 1/2" tube for 1 1/4"
radius, 3" tube for 1 1/2" radius and 4" tube for 2" radius
To change radius head or tube for one of a different size:
If changing to a smaller radius, swap out the radius head first by removing
one bolt at each end of the brake that holds the head in place, and install
a smaller size radius head. Now use the machine thread adjusting bolts on
each end of the brake (there are 4 adjusting bolts, two at each end) to
lower the radius head to just above the table, and then raise the apron
roller to about 1/4" below the radius head. You can reduce or increase the
clearance between the radius head and the apron roller to suit your need.
You can also taper one end wider than the other.
If changing to a larger size radius, before removing the radius head, run
the two adjuster bolts on each end to their widest separation of the radius
head and apron roller. Now replace the radius head with a larger size. Next
adjust the radius head down to just above the table, and then bring the
apron roller up to about 1/4" below the radius head.
If the radius head you are installing has a tab on one end, place the tab
under a block welded to the bed of the brake. This prevents the radius head
from rotating while forming material, and it is why you do not need to clamp
