Short offsets (threading issue)

Using 3/4'' rigid the other day, i was bending a small offset. 1" rise on greenlee hydraulic bender, with a total length of 5 1/2".

As u can imagine, w/ a radius of 9" this was a pain, but i did finagle my offset into the dimensions i needed.

The problem occurred when i tried to thread the piece. I left plenty of excess conduit on both ends. Measured the distance between the bends and had plenty of straight run to thread.

The problem occurred when i proceeded to use the pony, because the take up on the end is a about an 1 1/2" before the threading actually starts. The pony will actually catch on the bend before all the straight run is threaded.

After starting the threading on both ends i had high hopes the teeth were reversible to compensate for this.........they were not.

Do they make die's especially for these kind of situations, or is this just a wasted cause?

Thanks in advance for any responses.
 
Thru the years I have seen some small dies, but I couldn't tell you if they would work. I might be tempted to cut off the back side of an extra die (the part where the pony grabs) and use a 24" or 36" pipe wrench to turn the die.

BTW, nice bend!

Well they have the template now, I'd lay some string on it now and do what's stated above. :)

I'd also consider an "L", they have the convertable one's where one can change it to suit just about any application. The draw back is these are the expence of it... but 5.1/2" is right in the neighor of an "L". But something might still need a kick!

You are a much better conduit bender than I ever will be. There is no way I could figure out how much longer than 5.5" I need to cut and thread a piece of conduit in order to make this bend and have a 5.5" nipple. There is also no way I could bend a piece of 3/4 rigid that short, and I believe if you screwed it into a coupling of another piece of pipe (then try to bend it) you would wind up breaking off the threads on the nipple.
 
How about using an offset nipple coupled with one or two short nipples?

An offset nipple, two couplings and two chase nipples might be long enough.

Added: Could you have simply relocated one of the knockouts?

NO they dont

Heres what we do small offset on 3/4 use a hickey after treading . Option 2 screw on threader hand die from sears there real small and npt threads are fine .

But just buy a offset nipple its cheap and the labor to do that is a waste of time .
 
I don't really have any good advice other than to say the trick to running rigid is to visualize how to run conduit without putting yourself into these kinds of positions where you need to bend/thread such short stubs of conduit. Rigid is a labor killer if you're not careful, you really have to pay attention. It can easily take the inexperienced guys twice as long, just because they don't plan there bends right or how they'll twist that 90 on.

To answer your question, can you switch to flex or possibly use a threadless connector on one end?

If you have robroy dies they might give enough clearance around the bend to finish the threading.









Ive never seen a hydraulic bender, or any other kind, that would bend an offset in a 5.5" nipple.

I never said I would use his bender, I would use a hickey. ANd yes, it would be tough, but it could be done. I would have planned my layout better
