In this detailed tutorial you are going to build a bench top bender that bends rod and bar stock for your decorative welding and metalwork projects.
This bender can bend up to 1/2" diameter rod or 1/2" thick flat bar.
It's a good quality tool that won't cost very much to make. All you pay for is the materials which should not be much more than $90, depending on the cost of steel at the time or your purchase.
You can buy a new or used Chinese made bench top bard and rod bender for just under $90. But then you have a Chinese made bender that will work, for the time being.
This bench top bender can be bolted to any surface with four 3/4-10 bolts. It can also be welded or clamped down.
For simple visual operating instructions of a similar bench top bar and rod bender search for the 'harbor freight bender' on YouTube or watch this video (it's a little shaky):
We have a 12 page set of blueprints for these bender plans if you need more detail. However you may find that the following illustrations and directions are enough. Just let us know if you need them.
Step 1: Cut stock to length.
Step 2: Clamp two 30” pieces of the cut flat bar together and machine according to the bench top bender drawing BND-A below. This will make 2 identical pieces.
BND-A: Fixed Arm
Step 3: Clamp two remaining 30” pieces of the cut flat bar together and machine according to drawing BND-B. This will make 2 identical pieces.
BND-B: Pivoting Arm
Step 4: Clamp the two 20” pieces of the U-Channel together and machine according to drawing BND-F. This will make 2 identical pieces.
BND-F: Mounting Supports
Step 5: Clamp the two pieces of the 4-1/8” long angle steel together and machine according to drawing BND-D. This will make 2 identical pieces.
BND-D: Pivoting Arm Box
Step 6: Gather parts BND-A (qty 2) and both the 5-5/16” angle steel pieces (BND-C) and lay them out on the welding surface. Position them according to the bench top bender drawing BND-A1 and tack weld the parts in place. Double check alignment and complete the welds.
BND-A1: Fixed Arm Weldment
Step 7: Gather parts BND-B (qty 2), BND-D (qty 2), and BND-E and lay them out on the welding surface. Position them according to drawing BND-B1 and tack weld the parts in place. Double check alignment and complete the welds.
BND-B1: Pivoting Arm Weldment
Step 8: Gather all components and place on work bench. Assemble pieces according to attached print BND-AA and below drawings
Refer to the parts list at the beginning for the following weldments.
