Eastwood HIGH-CAPACITY TUBING BENDER Instructions Manual page 9

1. Slowly and steadily pull on the Bender Handle, bending the workpiece tubing
as you go.
2. When the Bender Handle is at the end of its travel, stop and very gently pull
it back several degrees releasing the Ratchet Teeth from the Drive Sleeve
(Fig 14).
3. Reposition the Ratchet so that Drive Teeth further down the Ratchet fully
engage the Drive Sleeve (Fig 15).
4. Once again, slowly and steadily pull on the Bender Handle, bending the
workpiece tubing as you go. When the Bender Handle at the end of its travel,
stop and very gently pull it back several degrees releasing the Ratchet Teeth
from the Drive Sleeve.
5. Once the entire usable length of the Ratchet has been reached and no more
bending range is available, the Ø 7/8" x 5-3/8" [Ø 22mm x 136 mm] Drive
Pin (M) must be pulled out and relocated in the Drive Link and further toward
the center of the Die (Fig 16).
notE: on average, the workpiece tubing will bend up to approximately
40° for each full travel length of the Ratchet).
6. To achieve more bending range; repeatedly pull the Drive Pin from the Curved
Die and Drive Link Assembly and move to another hole further inward on the
Die (Fig 17).
7. Once again, place the Ratchet with the Teeth completely engaging the Drive
Sleeve of the Drive Link Assembly.
8. As previously, slowly and steadily pull on the Bender Handle, bending the
workpiece tubing as you go. Watch the position of the Pointer on the Degree
Wheel as you approach your desired angle (Fig 17).
iMportant notE: There will be a certain amount of "springback" meaning
that you must pull several degrees past your gauge target then allow it to
"spring back" to the final degree mark. This varies widely according to the
particular material, diameter and thickness. Chromoly and high carbon steel
will generally have more "springback" than milder steels and aluminum. This
is one reason that some "trial and error" must be performed to explore the
properties of the material before working on a final project piece.
tECH tip: Once you are familiar with the characteristics of the
Eastwood High-Capacity Tubing Bender and how it reacts with
your most commonly formed tubing sizes, materials and bend
amounts, it is a great idea to create a series of "Templates" that
you can use as a pattern. For example: if you frequently use
Ø 2" Chromoly steel tubing, you may want to create templates in
22.5°, 45°, 90°, 120° & 180° and more as needed. On these, mark
the amount of material required to make each bend and
the amount of "springback" encountered.
