- MODEL 3 TUBE BENDER
- Assembly & Operating
- © Copyright 2004 by J D Squared
- 1) The tube bender may be mounted
to anything rigid enough not to twist or move during the bending
operation. To mount the bender
- drill two 3/4" holes 2"
inches apart through the mounting surface. The front cover shows the
bender mounted on the optional
- pedestal. NOTE: You can use the
Frame Base to help position the holes the correct distance apart for
- 2) Assemble the bender's frame
assembly as shown below.
- A) Place the Frame Base on your
mounting surface aligned with your drilled 3/4" holes.
- B) Place the Lower Frame Link with
the notched side to the left on top of the Frame Base aligned with
the two 3/4" holes.
Assemble the Ratchet and Swing Lever exactly as shown in figures 1,2
& 4 using the 3/4" pin and two 1/8" spring pins.
- The Swing Lever must rotate almost
a full 180 degrees . If the Swing Lever is installed upside down you
will be unable
- to engage the next ratchet tooth
during bending. Please, double check it. For hydraulic adapter
installation see page 3.
- D) Place the Swing Lever and the
1" Collar on one of the two Spacer Tubes (1" OD tubes). Do
not tighten collar.
- E) Install the Upper Frame Link,
Ratchet assembly and 1" Spacer Tubes as shown above. Hand
tighten the bolts.
- F) Insert the 1" Frame Pin
into the 1" Frame Link
- hole. Slide the 7/8" Frame Pin
into hole #5.
- Tighten the 3/4" nuts as
tightly as possible, while
- insuring the two pins are perfectly
- slide easily through their
- G) Raise the Swing Lever to the
middle of the Tube
- Spacer and lock into position with
the 1" Collar.
- H) Install Degree Plate as shown.
Use only your
- hand to snug down the nut. This nut
- wrench tightened. This allows you
to easily adjust
- the Degree Plate while bending.
- 3) The two Drive Links are
assembled next. Using the
- two 3/4" OD Drive Link Spacer
Tubes, two 1/2" bolts,
- four 1/2" washers and two
1/2" nuts, assemble the two
- Drive Links as shown in figure 3.
The word 'TOP' must
- be face up on both links. This is
- because three of the four 7/8"
drive holes are offset to
- the right. Hand tighten only.
Insert the two pins into
- their respective holes to help
alignment. Lay the
- assembly on its side to further
help alignment and
- wrench tighten securely.
- 4) Remove all pins from the Drive
Link assembly. With the word 'TOP' facing up, Install the Drive Link
assembly into the Frame
- assembly using the 1" Frame
Pin. See figure 4. The bender is now assembled and ready for the die
set to be installed.
- NOTE: The tube bender requires a
handle made of 1" x 2" rectangular tubing with a wall
thickness of .083" or .095", cut to 54" long.
- The bender does not come with a
handle because the shipping cost alone are more than an entire
length of this tubing. We can
- supply it if absolutely necessary
at an additional cost, however in keeping with the budget minded
idea of the Model 3 Bender, it
- is less expensive to supply your
own handle. There is absolutely no need to fabricate a fancier
handle. A simple piece of rectangular
- tubing works the best. NOTE: A
54" long handle should allow the average user to bend 1
3/4" x .095" wall mild steel tubing using
- just one hand. If bending
chrommoly, DOM or larger tubing and find you desire more leverage
to reduce the bending effort
- required, you may extend the handle
as needed. Usually a 2 ft. extension is sufficient. If bending
smaller tubing, 1" OD for example,
- we generally use a handle only
