SNUG BOLT SO TUBING DOES NOT MOVE.

DEGREEINDICATOR

WHEN USING THE DEGREE INDICATOR IT WILL BE NECESSARY TO JACK THE HYDRAULIC JACK UNTIL ALL SLACK IS TAKEN OUT OF THE DIE SET. AT THIS POINT, SET THE INDICATOR AT ZERO. YOU CAN NOW BEND THE TUBE ACCURATELY TO ANY DEGREE. REMEMBER THERE IS ALWAYS “SPRING BACK” ON TUBING SO IT IS NECESSARY TO BEND PAST THE POINT THAT YOU ACTUALLY DESIRE TO ALLOW FOR THIS. WE SUGGEST USING A TEST PIECE OFTUBING TO DETERMINE THE AMOUNT OF “SPRING BACK” FOR EACH TUBING SIZE, BEFORE STARTING THE JOB.

STEEL DIE

ALUMINUM BAR LINE BAR & DIE UP EDGE TO EDGE.

BENDING INSTRUCTIONS
IN THE NEXT FEW PAGES, WE ARE GOING TO TRY TO EXPLAIN A FEW THINGS ABOUT BENDERS & GIVE SOME EXAMPLES & EXPLANATIONS ON MAKING BENDS. WE ARE GOING TO TAKE YOU THROUGH A STEP BYSTEP 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. THE GENERAL RULE, AS FAR AS THE QUALITY OF THE BEND IS AS FOLLOW: THE THCIKER THE WALL SIZE AND THE SMALLER THE DIAMETER OF THE TUBING BECOMES, THE BETTER THE BEND.THIN WALLTUBING WILL FLATTEN SOMEWHAT ON ITS OUTER DIAMETER. THIS IS COMPLETELY NORMAL FOR ANY BENDER OTHER THAN A TRUE MANDREL BENDER. A MANDREL BENDER USES A STEEL BALL OR SIMILAR SHAPED DEVICE WITH AN OUTSIDE DIAMETER SLIGHTLY SMALLER THAN THE INSIDE DIAMETER OF THE TUBING BEING BENT. THIS HAS THE EFFECT OF THINNING THE WALL THICKNESS ON THE OUTSIDE OF THE TUBING, HOWEVER THE ROUNDNESS OF THE TUBING ISPRESERVED ALMOST PERFECTLY. EXHAUST HEADERS ARE BENT WITH MANDREL BENDERS. IF A COMPANY TELLS YOU THEIR BENDER IS A MANDREL BENDER AND IT DOES NOT USE INSIDE MANDRELS, BEWARE!!! TRUE MANDREL BENDERS ARE EXTREMELY EXPENSIVE. BEFORE WE START WITH BENDING CALCULATIONS WE ARE GOING TO LIST A FEW ITEMS OF IMPORTANCE.

DANGER!
PIVOT POINT MUST BE LUBRICATED. (ALL PURPOSE WHEEL BEARING GREASE WORKSVERY WELL.) WHEN BENDING, DO NOT LET THE END OF THE FOLLOW BAR GET ANY CLOSER THAN 2” FROM THE EDGE OF THE ROLLER. IF NECESSARY, RELEASE THE TENSION ON JACK & SLIDE BAR BACK.

2” MIN. SMALL DIE INSTALLATION

ROLLER

THREADED ROD AFTER INSTALLING DIE & FOLLOW BAR, REMOVE “PLAY” BY UNSCREWING THREADED ROD IN JACK UNTIL TIGHT, NOT BY PUMPING THE JACK.
