New Member here!!

Does anyone know of a machine that makes 90 degree bends on multiple 3/4" or 1" Rigid Galvanized Conduits at one time???
I know I saw one about twenty years ago in the "Mill" on a job.
If I remember correctly, it bent either four or six conduits at one clip.
I have seached the net and cannot locate one.
Any ideas??

can't say I have ever seen such an animal. Not much call for anything of the sort around my area.

I've never seen one, but I've heard you can order a Chicago type bender with such a head. I suppose it would be great for deck work.

I remember using one back in the late 70's doing a WWT plant. It's a shoe for a Greenlee 555 bender. You will have to look real hard in order to find one because I don't think Greenlee makes them anymore. You might have to find some old guy that might have one in his basement or shed.
Good luck!

I, for one, don't think you're on drugs. I remember a couple years ago someone invented a bench-mounted bender that had mutliple shoes, an electric motor, and a roller-type contraption for bending 2 or 3 pipes at the same time. There were two sets of shoes, so you could do offsets in one shot.
I was intrigued, to say the least, but quickly decided that it wasn't worth investigating as I never had need to make more than 2 or 3 identical bends in a racked run more than 1 or 2 times a year (something I can do with a hand bender). I didn't think it would have been worth the money to buy a high-dollar bender to use, store, haul, and set up just a couple times a year. But if someone was to do a lot of industrial, with lots of parallel racked runs would be a different story.

Thanks Sparky...
It's for deck work...making muliple 90's at a clip....not even offsets... just ninetys

Thanks John,
That's not it....but the best I've seen!
Been looking for hours!!!!
The machine I'm talking about is a heavy/portable/bench type bender.
I believe it had five horizontal grooves on the table top. There was a five pipe shoe standing at the end of the table.
you slid in the five conduits to the desired length and when depressing a foot switch, a roller driven off of a wheel below, rose in a vertical track...driving the pipe up against the shoes and bending five 90's at one time.
I hear it was invented by an electrician in New York that worked for a company called Simpssom Electric. Approx. 1970-1975.
That company did alot of high rise re-inforced concrete jobs and had a mill at the street level.
As a matter of fact...Judd Hirsch (the actor in Taxi, had a brother (Abe..maybe) He ran this machine on the job I was on for DAK Electric...kind of a throw-off of Simpson....
Been searching every angle....Dak,Simspon,patents in the 17970's/80'...you name it.....almost exhaustd all ideas of searching.
Reason is...I'm starting a high rise in Brooklyn, N.Y. and would love to have this machine. I'm thinking of building one. It was not a complicated design at all!
Could've had it built in the time I've been searching!!! LOL

John,
Where did you get that picture???

I also recall a hand bender that would do two 90s at once.


This http://www.conduitbender.net/ is what I was thinking of earlier.
