Warning: Welding Precautions
If you perform any welding using the materials that have been bent by this tool, it is important that
you remember that there are additional safety precautions that must be taken. Of course, you should
follow all warnings and instructions provided by the manufacturer of the welding equipment used.
Be aware of flying sparks. Only weld in an area that does not contain any materials which can be ignited by
flying sparks. Extinguish any significant flying sparks before continuing to weld.
Protect yourself and others around you from burns which can be caused by flying sparks.
Make certain that you have a fire extinguisher accessible.
Never weld in an atmosphere which might contain flammable fumes.
Periodically during welding, and after completion of a job, inspect your area for any ignition which may have
been caused by flying sparks.
Never leave your welder unattended while it is plugged in.
Always wear electrical insulating clothing, gloves and shoes while using your welder.
Flying sparks can cause injury, and hot materials can cause burns. Please wear appropriate safety clothing,
and observe precautions to prevent burns or injury to yourself or others.
Wear protective clothing such as heavy gloves, apron and boots.
Do not look directly into the welding arc without appropriate protective eye shields.
Do not allow others to look directly into the arc without appropriate eye protection.
Wear protective gloves while welding. Welding causes the metal to become very hot, which can cause burns.
Do not touch welded areas until you are certain they have completely cooled.

Warning: Welding Precautions (Continued)
The electrode, and especially the welding rods become very hot during welding. Exercise extreme caution to
prevent burns to yourself or others.
Note: Read and adhere to all warnings and instructions in the instruction manual provided by the

manufacturer of the welder being used.
Assembly
Your Compact Bender-Floor will require complete assembly prior to operation. It is important that you read
the entire manual to become familiar with the unit BEFORE you use the Compact Bender. Before assembling
your Compact Bender be sure that you have all parts described in the Parts List on page 9.
When assembling your Compact Bender-Floor, it will be helpful to refer to each of the operational Figures as
well as to the Parts List and Assembly Diagrams on pages 9-11.

Basic Operation

Following are instructions on the primary uses of your Compact Bender. Additionally, information is included
on the many ways to use your Compact Bender, along with specific examples. Becoming familiar with the
Compact Bender and its many uses will allow you to make a variety of useful items.
As the operator, you will have to decide on the way in which you will be using your Compact Bender. The following are the basic steps you will need to take when working with the Compact Bender.
Use an appropriate measuring device to measure and:
•

Decide on material and measurements to be used.

•

Decide on the appropriate Die. Decide on the best placement of the Die for your particular bend.

•

Decide on the appropriate attachment, Stop Block or Right Angle Bend. Correct orientation of Stop
Block.

•

Insert stock into the Bender and position it properly. Make the first bend.

•

Check the angle and direction of the bend.

•

Make all consequent bends. Adjust the workpiece as needed.
Warning: Keep fingers and hands away from moving parts at all times.

How the Holes Are Numbered

Throughout this manual, the holes are often identified by a specific number, i.e., the 3rd hole in the
Handle.There are five (5) holes referred to in the Outer Handle/Die Receiver (#9) and 5 holes referred to
in the Ring Assembly (#10). For clarification of each hole and its corresponding number, please refer to
Figure 3 below.

Use of the Support Pin with the Square Stop Block
Step 1)

Place the Support Pin (#5) into the hole under the Square Stop Block (#3) so that the Square
Stop Block (#3) will sit correctly in relation to the Ring Assembly/ Die Receiver-see Figure 4.

Long Hitch Pin (#1)

Step 2)

Insert the Support Pin (#5) in the hole so that it sits under the Stop Block but does not block
the Long Hitch Pin (#1) from going through the hole in the Stop Block and into the lower hole
in the Ring Assembly (#10).

If the Stop Block is correctly placed you should not have to clamp the workpiece into place. When working
with exacting bends, however, it may be helpful to clamp the workpiece into place using vise-grip pliers.

#38470

Page 6

Placement of Die
Dies are placed at one or two different locations depending on the bend to be made:
•

A die can be used in conjunction with the Short Hitch Pin (#2) at the intersection of the Outer Handle/Die
Receiver (#9) and the Ring Assembly/Die Receiver (#10).

•

The Die can also be placed on the Outer Handle/Die Receiver (#9).

•

Two Dies can be placed so that one is on the Outer Handle/Die Receiver (#9) and one at the center point
where the Outer Handle/Die Receiver (#9) and Ring Assembly/Die Receiver (#10) intersect-see Figure 3.

Orientation of the Handle
The Handle is always oriented up and on the right side. The Handle is always moved clockwise
when a bend is being made.
Use of the Square Stop Block
The Stop Block is so named because it stops the workpiece from turning while the workpiece is being bent,
thus “stopping” movement of the workpiece.
When bending your workpiece, place the Square Stop Block (#3) over one of the holes in the Ring Assembly/
Die Receiver (#10). You will have to do some testing to determine placement of the Square Stop Block. You
will need to place it over the appropriate hole for the bend you desire and the Die you are using.
Step 1)

There are four (4) key positions to place the Square Stop Block (#3) in while bending. The
four positions (as seen from looking down on the top of the Square Stop Block) are identified
in this manual by a letter; A, B, C, or D. See Figure 5 on the next page, for the letter and the
corresponding position of the Square Stop Block.

Warning:

Always position the Stop Block so that it’s hole is oriented to the right side. Even
though another side of the Stop Block may actually face the work piece. If the hole is
oriented left instead of right, this will result in the Stop Block turning which will cause the
workpiece to move.

Step 2)

Set the appropriate Die into place on the Outer Handle/Die Receiver (#9) between the upper
and lower fork. Secure the Die in place by inserting the Short Hitch Pin (#2) through the
Outer Handle/Die Receiver (#9) and the Square Stop Block. The Square Stop Block (#3) is
held in place against the stock as shown in Figure 7 on page 12.

Step 3)

Set your workpiece into position. With the Handle (#9) in the starting position, set the Square
Stop Block (#3) as close to the Long Hitch Pin (#1) at the center position, as possible.

Note:

To avoid large spaces between the Stop Block, the Center Pin and selected Die, orient the
Square Stop Block differently, or if possible, move it one hole closer to center.

#38470

Figure 5 - Stop Block Orientation

Use of the Right Angle Bend Attachment
You will want to use the Right Angle attachment
instead of the Stop Block when making a right angle
or sharp bend in the stock.
The Right Angle Attachment fits on the Compact Bender only one way.
Step 1)

Install the Support Pin (#5) under the Right Angle attachment. This will raise it up so that it
sits above the Ring Assembly/Die Receiver-see Figure 6.

Step 2)

Set the Support Pin into the 3rd hole on the Ring Assembly/Die Receiver (#10). Line up the
hole in the top of the Right Angle Bending Attachment (#7) with hole #2 in the Ring
Assembly Die Receiver (#10)-see Figure 6. Insert the Long Hitch Pin (#1) through
the second hole in the Ring Assembly/Die Receiver(#10) to secure the Right Angle Bending
Attachment (#7) in place.

Note:

Your workpiece will not need to be clamped when you are using the Right Angle
Bending Attachment (#7).

Step 3)

Mark the stock at the points that you desire to make a bend. Line up the stock so that the
Right Angle Attachment hits directly at the midpoint of your mark.

Insert Long Hitch Pin (#1)

Support Pin (#5)

Figure 6-Right Angle Bending Attachment
The Stop and Adjustable Stop Loop
Many times while using the Bender you will need to make repeated bends of the same type and angle. In
these instances, using the Adjustable Stop Loop (#26) or the Stop (#4) will save time and allow for precisely
the same bends.
Adjust the Stop and Adjustable Stop Loop with a piece of scrap metal prior to using your actual workpiece.
This will assure accuracy and aid in obtaining ideal placement of the Stop.
#38470
Page 8

Stop
Step 1)

Test and decide the amount and distance of Handle rotation to make the desired
bend.

Step 2)

Place the Stop (#4) into the next hole (clockwise) after your rotation is complete.

Adjustable Stop Loop
Use the Adjustable Stop Loop (#26) for stops where a finer adjustment is needed. The Adjustable Stop Loop
allows for more precise stops as it can be adjusted whereas the Stop (#4) is simply placed into a hole on the
Ring.
Step 1)

Test and decide the amount and distance of Handle rotation to make the desired
bend.

Step 2)
Place the Adjustable Stop Loop (#26) directly at the point where the rotation of the Handle

is to end. Insert Mounting Bolt (#25) through 3/8” Washer (#24) to hold the Adjustable Stop
Loop in place. Tighten on Washer (#24) and Nut (#27).
Step 3)

Try a test bend and adjust the Adjustable Stop Loop (#26) as necessary to obtain a precise
bend.

Now that the basic operating instructions have been described; it is time to practice using the Compact
Bender. We are going to show you how to make several useful items such as handles and anchor bolts. We
will also show you how to make letters of the alphabet for use in making decorative signs. Once you practice
on the Compact Bender and learn its capabilities, it should be easy to come up with additional uses for the
Compact Bender based on your interests and work requirements..

MAKING HANDLES

Project Ideas

Round Stock

To make handles using round stock, the Square Stop Block (#3) is used rather than the Right Angle
Attachment.
Use a 10” piece of 5/8” round stock and two sections of flat stock for the ends. The measurements given are
general guides only. Measurements should be adjusted according to your preferences and specific needs. If
changing stock size, you will have to experiment to obtain the best points for each bend.
Step 1)

Place the Square Stop Block (#3) into place.

Square Stop Block (#3)

5/8” Round Stock

Extend 2” past Die
1” Die

Figure 7
Step 2)

With the Handle (part #8/9) in the normal position, place the 1” Die on the Center Pin. Place
the 2” Die in the 2nd hole- as in Figure 7. Insert the round stock so that the end extends 2”
down past the 1” Die - see Figure 7. Make the first bend at 90 degrees.

Step 3)

Remove the round stock from its original position. Place the second end into the
Bender in the same way as the first bend. You want both ends to be bent in the
same direction. Make the second bend at 90 degrees. Remove from the Bender.

Step 4)

Decide on how you want the round stock to fit with the flat stock. Drill 5/8” holes
into the flat stock at the desired position. Insert the round stock into these holes.

Step 5)

Weld the flat stock into place from the side where the round stock exits the flat
stock. Smooth away any excess weld material so that the handle sits flush in its place.

Flat Stock
To make handles using flat stock, the Right Angle Bending Attachment (#7) is used rather than the Square
Stop Block (#3). Use a 10” (minimum) length of 3/4” wide x 1” thick hot-rolled flat stock.
Step 1)

Set the Right Angle Bending Attachment (#7) into place as previously outlined.

#38470

Step 3)

You may want to set up the Bender with the Adjustable Stop for repeated bends.

Step 4)

Flip the stock around and insert the end opposite the bend. Insert it to the 2nd mark and
make a 90 degree bend.

Step 5)

Reverse the stock and make the 3rd bend at the 3rd mark. Repeat for the other end and
make a bend at the 4th mark.

Step 6)

With a sander or grinder remove any sharp edges or rough spots.

Making Tube Clamps

Single Tube Clamp

The following instructions are for a 1” Inner Diameter tube clamp using 4-1/2” long, 3/16” thick x 1” wide flat
stock. See Figure 7 as a reference.
Step 1)

Place a 1” die on the center point hole and secure it in place with the Long Hitch Pin (#1).

Step 2)

Using the Short Hitch Pin (#2), place a 1-1/2” die in the Outer Handle 2nd hole.

Step 3)

Set the Square Stop Block (#3) into the 1st hole on the Ring Assembly (#10).
Orient it as in B (Figure 5 on page 8 of this manual).

Page 13

Step 5)

Bend the stock past 180° until the die on the Outer Handle slides off of the stock.

Step 6)

Remove the Square Stop Block (#3) and the die. Put on the Right Angle Bending
Attachment (#7).

Step 7)

With the workpiece as tight against the Long Hitch Pin (#1) in the center as is
possible, make a right angle bend-see Figure 10.

Figure 10

Making Anchor Bolts-U Bolts

Figure 11

Following the directions shown below will allow you to make a 12” Anchor Bolt from a 14-1/4” blank (see Figure 11 above).
As with all bending, you can make shorter or longer Anchor Bolts by changing the size of the blank. Use a
scrap piece to experiment with length and placement of bends.
Step 1)

Place a 1” die on the center point hole and secure in place with the Long Hitch Pin (#1).

Step 2)

Using the Short Hitch Pin (#2), place a 2” die in the Outer Handle 2nd hole.

Step 3)

Using the Long Hitch Pin (#1) set the Square Stop Block (#3) into place. Set
the Stop Block in either position B or D (see section: Using the Square Stop Block). Position
B (3/8” or 1/2” diameter bolts) or D (5/8” diameter) according to the bolt being used.

Step 4)

Place the stock into the Bender so that the unthreaded end is extended sufficiently beyond
the Square Stop Block (#3) - 1/2” for 3/8” bolts; 5/8” for 1/2” bolts, and 1/4” for 5/8” bolts).

Step 5)

Move the Outer Handle (#9) until you have obtained a 90 degree bend.

Making Individual Letters of the Alphabet
Directions and tips for creating each letter of the alphabet are
included in the following section. The information given is based on
use of 3/16” flat stock, and a 1” max. width. The letters created by using
these steps are six (6”) high and 1” deep.
When creating each letter make certain that you use hot-rolled mild steel. Aluminum can also be used.
The steps are fairly precise, but as with all bending functions you may create you own unique designs and
measurements through trial and error. Use a scrap piece of metal for practice prior to creating the actual
workpiece.
Use a protractor to measure each angle.
To make the following letters use the Right Angle Bend Attachment (#7) for each bend.
Tip:

Always double check the measurements on each angle you bend.

Note: Use the Stop or Adjustable Stop for repeated bends at the same angle.
Note: After each letter has been formed, smooth away any sharp edges using a grinder or by

sanding.
