- Jon Dougherty, our Education Director, walks us through bending rigid conduit and how to properly thread a pipe using a power pony.
Jon is one of the most licensed electricians in the United States, and we are proud to have him. Check out our other videos on How to Bend Conduit for a 3 Point Saddle, 90 Degree Stub Up, Box Offsets, and more! - Навчання та стиль
If you are doing rigid conduit it’s a good practice to spin your boxes, Meier hubs, unilets on first to see how they fit. You may need to change the depth on the threads or clean them up first to thread them on tightly. This is reaaaal important.
I don’t recommend using minnies because they are easily crushed or bent compared to malleable 1 holes with back straps.
They make 3 1/4” deep strut and it’s a better install vs using back to back 1 5/8” strut.
Always spray the cold galv on after you threaded your pipe which contains the mess.
Threading rigid conduit is not a 2 person project…you can fasten the tripod legs down or use a sturdy rope to make a 3’ loop that is tied to the foot, using a piece of wood can’t stop it from flipping on larger pipes or if the tripod is an old p.o.s
Finally when bending your first piece you should have calculated the gain which on newer 1” foot benders is somewhere around 4 1/2”…it’s verrrrry good to know because you cut and thread first then bend if need be.
When using a foot bender I highly suggest you take the opposite end of the conduit and stick it on a wall or curb or something sturdy so it cannot slide around on you. You can really hurt yourself if it slips.
Just stub 90 everything and then cut and measure. More accurate and easier to spin on. Also, pipe threading can easily be done with one guy and having an actual reamer is better than a file or piece of all thread. Good video
No shit...
Nice work!!
Thanks, very informative.
Thank you for showing how to spin it on. It maybe the most difficult part 😂
You don't have to deduct for the 90 if you use the star and pull toward the measurement
Great video! But your toolie 54 seconds in , is oiling for you in the wrong spot
Too many times I've seen that power pony catch and come over top. Have your partner stand to the side so he doesn't get whacked by power pony with dull dies . 3/4" heavy used dies don't always get new teeth right away Good habit to have when you go to bigger conduit. That is why you see the chain or rope on TriPod leg to help. That is reality even with Hogs Head
If u had say 2" conduit would you have to assemle the whole thing and set in place, not going to get much flex out of it like the 3/4
The deduction for 3/4 pipe is 6". Why is he using the 8" deduction?
I believe all the deductions for rigid 3/4 are the same as EMT 1 in. Someone correct me if I'm wrong. I'm still learning.
Your deduction is based on the bender you’re using, it’s a 1” bender so you use your deduct in accordance to that, 8”.
This guy doesn't know how thick double deep strut is by memory. I wouldn't follow his instructions. Also, anybody who has done any rigid knows that threads are 7/8.
