5-SB BENDER -DIE INSTALL- QUICK RELEASE NOTES THE TENSION BOLT SERVERS TWO PURPOSES: 1) IN MOST CASES IT IS NECESSARY TO KEEP TENSION ON THE BOLT TO PREVENT THE RELEASE FROM OPENING UP AND PREMATURELY RELEASING THE TUBE. 2) WHEN APPLYING TENSION ON THE BOLT YOU DO NOT WANT TO OVERTIGHTEN THE BOLT. ONLY APPLY ENOUGH PRESSURE TO KEEP THE RELEASE SEATED AND TO PREVENT ANY SPRINGBACK.
105-SB BENDER -IMPORTANTCHECK THESE ITEMS BEFORE STARTING TO BEND. TIGHTEN TENSION BOLT SO TUBE WILL NOT SLIP. BE CAREFUL NOT TO OVER-TIGHTEN & DAMAGE TUBE. RADIUS OF MAIN DIE MUST BE CLEAN. ABSOLUTELY NO GREASE! FOR A FRICTION FREE BEND, ALWAYS LUBRICATE THE BACKING BLOCK. ALL PURPOSE WHEEL BEARING GREASE WORKS VERY WELL. NOTE: YOUR BACKING BLOCK HAS “TOP” STAMPED ON IT. THIS MUST ALWAYS FACE UP. ****BACKING BLOCKS WILL VARY IN SHAPE & DESIGN. ABOVE IS ONE EXAMPLE.

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 ON REMINDER. ALWAYS WORK ALL BENDS OFF THE CENTER MEASUREMENT BECAUSE DIIFFERENT 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 BYE 360 EXAMPLE: 6 INCH RADIUS, 90 deg. BEND WOULD BE: 6 x 6.28 x 90 / 360= 9.
FAQ’s Q: WHAT SIZE MATERIAL CAN I BEND WITH THE BRUTE? A: UP TO 2 ½”x .134 WALL STEEL TUBE AND 2” SCHEDULE 40 PIPE. Q: THE TUBE IS STUCK IN THE BENDER? A: SNUG THE TENSION BOLT ON THE QUICK RELEASE, THEN BACK OFF THE RAM. Q: CAN I UPGRADE THE HYDRAULIC CYLINDER? A: NO. THE HYDRUALIC CYLINDER IS PERFECTLY MATCHED FOR THE BEST RESULTS. Q: CAN I CHOOSE WHICH HYDRAULIC PUMP I WANT? A: YES THE MB-105-SB WILL WORK WITH EITHER AIR OR ELECTRIC PUMPS.
