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.
DRAW A PICTURE OF A PIECE OF TUBING.
B.
WE KNOW WE WANT A WIDTH OF 48”
C.
MARK TUBE IN CENTER.
D.
1/2 OF 48” IS 24”. MEASURE FROM THE CENTER OF THE TUBE TO THE
RIGHT 24” AND MARK THE TUBE. MEASURE FROM THE CENTER OF THE
TUBE TO THE LEFT 24” AND MARK THE TUBE.
E.
ADD ON 3 1/2” ON EACH SIDE, BECAUSE WE KNOW THAT IT WILL SHORTEN
UP THIS AMOUNT.
F.
WE WANT A DOWN LEG OF 40” AND FROM OUR TEST WE KNOW THE BEND
WILL ADD 8” TO THE LEG. IN THIS PROJECT WE WILL NEED 32” OF TUBING
ON EACH END, BUT HAVE ADDED AN EXTRA INCH FOR A SAFTEY FACTOR.
IT IS BETTER TO CUT A SMALL AMOUNT OFF THAN TO HAVE YOUR TUBE
COME UP SHORT.
STEP 5
LINE UP TUBING IN BENDER AS SHOWN AND MAKE THE FIRST BEND.
6” RADIUS DIE
YOUR FIRST BEND IS COMPLETED AND
THIS IS WHAT IT WILL LOOK LIKE.
