ASSEMBLY INSTRUCTIONS IN THE FOLLOWING INSTRUCTIONS WE WILL EXPLAIN THE ASSEMBLY OF THE BENDER. PLEASE READ EVERYTHING, BECAUSE SOME OF THE ITEMS ARE VERY IMPORTANT AND WILL SAVE YOU TIME LATER ON. THE BENDER IS DESIGNED TO BOLT TO A BENCH OR STAND. WE RECOMMEND INSTALLING IT ON A STAND. IT MAKES IT A GREAT DEAL EASIER TO WORK AROUND WITHOUT HAVING ANY OBSTACLES. INSTALL 1” PIN WITH SOME MULTI-PURPOSE GREASE. MAKE SURE IT WILL SLIP UP & DOWN EASILY BEFORE TIGHTENING BOLTS.
ASSEMBLY INSTRUCTIONS REMOVE 1” PIN FROM FRAME ASSEMBLY AND INSERT THROUGH END HOLES (AS SHOWN) INSERT 7/8” PIN AND 1” PIN FOR ALIGHNMENT (BEFORE TIGHTENING ½” BOLTS.) BOLT BOTH SWING ARM PLATES TOGETHER WITH ½” BOLTS & NUTS PROVIDED. BE SURE BOTH PLATES ARE FACING IN THE SAME DIRECTION (AS SHOWN) DO NOT USE WASHERS ON TOP OR BOTTOM. NOTE: PLATES MUST BE ALIGNED PROPERLY SO THAT PINS CAN SLIDE OUT FREELY. 1/2”x2 5/8” LONG SPACER SLEEVES (2) 1/2” BOLTS MUST BE TIGHT TO PREVENT PLATES FROM MOVING.
ASSEMBLY INSTRUCTIONS MAIN DIE INSTALLATION REMOVE 1” PIN, LUBRICATE PIN AND DIE SLEEVE, PLACE DIE IN BENDER FRAME THEN SLIDE PIN THOUGH FRAME AND DIE SLEEVE (AS SHOWN) INSERT PIN THOUGH SWING ARM AND FIRST HOLE OF MAIN DIE. DIE SLEEVE TUBE & BACKING BLOCK INSTALLATION 1. BENDER SWING ARMS MUST BE CLOSED POSITION AGAINST BENDER FRAME. 2. INSERT TUBE INTO RADIUS OF MAIN DIE. 3. PUSH BACKING BLOCK AS TIGHTLY AS POSSIBLE AGAINST TUBE, THEN INSERT PIN THROUGH BENDER FRAME AND BLOCK.
ASSEMBLY INSTRUCTIONS FOR A FRICTION-FREE BEND, ALWAYS LUBRICATE THE BACKING BLOCK. ALL PURPOSE WHEEL BEARING GREASE WORKS VERY WELL. TIGHTEN LOCKDOWN BOLT SO TUBE WILL NOT SLIP. BE CAREFUL NOT TO OVER-TIGHTEN & DAMAGE TUBE. NOTE: YOUR BACKING BLOCK HAS “TOP” STAMPED ON IT. THIS MUST ALWAYS FACE UP. RADIUS OF MAIN DIE MUST BE CLEAN. ABSOLUTELY NO GREASE! BACKING BLOCKS WILL VARY IN SHAPE & DESIGN. THE BLOCK SHOWN ABOVE IS JUST ONE EXAMPLE.
BENDING INSTRUCTIONS ENGAGE RATCHET AS SHOWN. PULL HANDLE IN DIRECTION OF ARROW. CONTINUE TO WORK THE RATCHET UNTIL YOU HAVE REACHED THE END, AS SHOWN IN FIG. C. FIG. A FIG. B FIG. D FIG. C QUALITY PRODUCTS BY PEOPLE WHO CARE WHEN YOU HAVE BENT THE TUBING AS MUCH AS THE FIRST POSITION WILL ALLOW, DISENGAGE THE RATCHET & REMOVE THE 7/8” DRIVE PIN. ROTATE THE SWING ARM COUNTER-CLOCKWISE UNTIL THE DRIVE PIN CAN BE REINSTALLED THROUGH ANOTHER HOLE IN THE BENDING DIE. BE CAREFUL NOT TO MOVE THE TUBE.
BENDING INSTRUCTIONS IN THE NEXT FEW PAGES, WE ARE GOING TO EXPLAIN A FEW THINGS ABOUT BENDERS & GIVE SOME EXAMPLES & EXPLANATIONS ON MAKING BENDS. WE ARE GOING TO TAKE YOU THOUGH A STEP BY STEP PROCEDURE SHOWING YOU HOW TO DETERMINE THE STARTING POINT OF YOUR BEND, HOW TO CALCULATE THE LENGTH OF TUBING YOU NEED TO START WITH, AND AS MANY WAYS AS POSSIBLE FOR YOU TO BE ABLE TO PRODUCE PROFESSIONAL, ACCURATE BENDS.
BENDING INSTRUCTIONS 36” 1 ½” 24” 12” STEP 2 TAKE THE 36” LONG PIECE OF TUBING AND MEASURE EXACTLY 12” FROM THE LEFT TO RIGHT. THEN MARK THE TUBE IN THE BENDER AND POSITION THE EDGE OF THE DIE EXACTLY IN THE CENTER OF THE MARK, AS SHOWN IN THE EXAMPLE. THEN MAKE A 90 DEGREE BEND. USE A CARPENTER’S SQUARE TO MAKE SURE YOU HAVE A PERFECT 90 DEGREE BEND. IF YOU OVERBEND, SIMPLY PLACE THE TUBE IN A VISE AND PULL IT BACK TO 90 DEGREES.
BENDING INSTRUCTIONS STEP 4 WE ARE NOW READY TO START A BENDING PROJECT. IN OUR EXAMPLE WE WILL FABRICATE THE MAIN HOOP FOR THE ROLLBAR ON A RACE CAR. WE USE THIS PROJECT BECAUSE IT IS A JOB REQUIRING MULTIPLE BENDS AND CLOSE TOLERANCES. WE ARE USING 1 1/2” TUBING, AND WE WANT A WIDTH OF 48” AND A HEIGHT OF 40” WHEN COMPLETED. A. B. C. D. E. F. DRAW A PICTURE OF A PIECE OF TUBING. WE KNOW WE WANT A WIDTH OF 48” MARK TUBE IN CENTER. 1/2 OF 48” IS 24”.
BENDING INSTRUCTIONS STEP 6 INSTALL TUBING IN BENDER AS SHOWN AND COMPLETE THE LAST BEND. AT THIS POINT YOUR ROLLBAR IS COMPLETE, BUT WE WOULD LIKE TO OFFER A REMINDER. ALWAYS WORK ALL BENDS OFF THE CENTER MEASUREMENT BECAUSE DIFFERENT METALS STRETCH DIFFERENTLY & IF YOU MAKE A MISTAKE ON THE FIRST BEND YOU CAN MAKE AN ADJUSTMENT ON THE SECOND BEND TO CORRECT THE PROBLEM.
HELPFUL INFORMATION NOTE: ALL ROUND TUBE RADIUS MEASUREMENTS ARE “CENTER LINE RADIUS” ABSOLUTELY NO GREASE IN RADIUS! THE DIE RADIUS MUST BE CLEAN & GREASE FREE AT ALL TIMES! TO MEASURE RADIUS: START AT IMAGINARY CENTER OF SLEEVE, MEASURE TO EDGE OF DIE. TIGHTEN BOLT SO TUBE WILL NOT SLIP NOTE: TO CALCULATE LENGTH OF TUBING USED IN A BEND, MULTIPLY RADIUS OF BEND X 6.28 X DEGREE OF BEND, THEN DIVIDE BY 360 EXAMPLE: 6 INCH RADIUS, 90 deg. BEND WOULD BE: 6 x 6.28 x 90 / 360= 9.
EXTENSION BAR USES SOME SMALL DIES ARE TOO SMALL TO DRILL DRIVE HOLES. IN THIS CASE THE OUTSIDE OF THE SWING ARM PUSHES AGAINST THE U-STRAP DRIVE PIN. U-STRAP DRIVE PIN HANDLE EXTENSION WITH SMALLER TUBE SIZES, THE RATCHET IS NOT NEEDED. FOR A QUICK BEND, SIMPLY INSERT THE HANDLE EXTENSION BETWEEN THE TWO BOLTS ON THE SWING ARM (AS SHOWN) AND PULL THE HANDLE AND SWING ARM AROUND TO CREATE THE DESIRED BEND.
