Posted another thread on the bender thing asking for helpgave some good pointersDrew some sketches and went after it…I´m building a bender similar to the HF compact benderSo far I´ve made the pedestal of 2 x 4 x 1/8 inch tube (40 inch high), 3/8 plate for the base, five dies of CR 1, 1 ¼, 1 ½, 1 ¾, and 2 inch, two “u” shapes of 3/8 x 2” flat bar HR, ext handle, etc.I´m planning to use a ¾ bolt for center pin and 5/8 bolts for the dies pins (all in the so called grade 8)  if they prove to be too soft, I will change for CR bar.Please if somebody has one of these would you measure the distance (center to center) between the first, second and third holes and post here?Thanks a lot,
Reply:Can't help you on the dimensions. But for real hardware try your local CAT dealer. They have many grades of hardware excceding grade 8 and are reasonably priced.A couple of 170,000 PSI min tensile strength bolts 3/4" x 3 1/2" = 3B-2968 $4.24ea5/8" x 5 1/4" = 9S-3224 $4.41eaMillermatic 251Century 180 migSpectrum 625 Syncrowave 250DX
Reply:I have one of these.If someone elese doesn't get to it, I will measure mine tonight when I get home and post them for you.
Reply:I measured my HF Compact bender and the distance from the center of the first hole to center of the second hole is 1 1/2".  From the second hole to the third hole the distance is 7/8" and that distance is the same for all the rest of the holes that are on that piece.There is a hole between the first and second one that is about 7/16" in diameter.  It is located exactly halfway between the first two holes.  Don't ask why it is there - I don't know.  Someone else may be able to answer that one.I could take a pic if you need one.  However it may not be until the weekend because of my schedule.ECAVE
