- Bending 20mm steel conduit bubbles both traditional methods and more modern! Using the Hilmor Shortie bender and both class 3 and class 4 conduit.
Managed to get one bubble within a sheet of paper to the obstacle!

Superb video,tips that actually work in practice. I tried the last tip for a bubble set using a sliding bevel instead of a angle gauge, it took the guest work out, leaving a nice neat job in white pvc conduit.
Many thanks looking forward to the next video.
Loved it, thank you
good stuff, especially using a magnetic digital angle finder. Don't understand why people aren't using them more to get the bends spot on.
Got a couple of tips to share. . .
For cutting Class 4 conduit, you can use a little adjustable pipe cutter (Screwfix 71782) to cut the pipe. Not what it's meant for, but works really well. Best is to snap the thing on the conduit, hold with one hand and rotate the pipe around. Nice square, neat cuts each time with only a little bit of cleaning up with a file.
These little pipe cutters also work really well when you have to cut existing conduit with wires inside without damaging them.
For when marking out trunking to fit conduit in there, put a maker pen in a stuffing gland, put the stuffing gland into a coupler, put the coupler on the end of a scrap bit of conduit, put a spacer saddle near the coupler.
From there, just put the whole thing against the wall and mark up where the hole is to be drilled with the marker.
Carry on.
Brings back memories of bending iron and copper pipes throughout a whole building.
If only the pipe material was made like that really thin wiring stuff with the melty plastic covering that goes around all sorts of corners 👍
Great video. Are you planning on doing video of a bridge over bigger items please??
I used the methods shown by the e-fixx team to help with several installs using stainless steel conduit (I work in an industrial food production setting), bearing in mind the cost of stainless, the conduit and all the accessories, I really do need to get it right first time, which I did thanks to e-fixx. Trying to bend the conduit I had to add about a 1.5 meter length of pipe to the bending arm for more leverage and was still hanging off it, bouncing as well lol (we won't go into threading the bloody stuff), but oh my word, the satisfaction of getting it right and the look of it on the wall, totally worth all the effort.
Totally agree on all counts!
We never really crossed over conduit but would tend to put an adaptable box in , it made more work obviously but working with council engineers etc they tended to take a bit of a dime view on such methods . Asking is the bend somewhere to hang your coat 😂. But I’m sure those days are long gone , I would have definitely loved that angle measure device . And as for working between to fixed points with bends, I just cut the conduit slightly longer and cut it to fit when I was happy with the bend . All that faffing about making something fit with one set length , just to save Two bobs of material . 😂. Still it’s nice to know people are getting the knowledge of working with conduit , in many ways it just can’t be beaten in certain applications . Well done in all you do to promote the industry , and the way you impart your knowledge onto the next generation of electricians . Best wishes and kind regards 😀👍👍👍
Thanks. Yeah this was just a demo of an approach you can take. Loads of other options.
Thanks mark I’ve got a digital gauge that will make bubble sets easier for me 👊
The combo of this method and my bender is crazy lol. Bubbles for fun over conduit lol
Good video mark. Would be good to have a section done in a clear plastic or perspex so you could see the singles in there. I enjoyed the video.
Good demonstration 👍
Cheers
The bender is expensive for low usage. Quite fancy the manual ones the Americans seem to use (you use them against the floor, and they have a foot plate), but can't make my mind up on whether they fit our conduit. They tend to be 3/4 and 1 inch.... Not sure if that works for us. So much more affordable under £100! Klein 56104)
Also, with complex bends in copper, I tend to run a pencil 'seam' down the length to help to keep bends co-planar. I have a manual 15/22 bender - shame you can't get the former for 20mm for these. I tried 20mm conduit using the 22m former, but the corner came out a bit flattened, as you might expect.
The foot ones are very hard work as we use a thicker gauge steel in the UK on conduit. But you can get them. Much harder to form than copper thats for sure lol.
How do you set the conduit in the bender at the exact center?
I'm only used to bending copper pipe. This is handy. Remember to like and subscribe viewers.
Thanks!
It would be great if u can demonstrate how you actually get your marks on the former in the first place.
Totally different for every former so irrelevant tbh. Pretty simple though with and angle gauge.
1: mark about 30mm down from the top of the former in pencil
2: mark conduit at say 300mm and put in the vice so that the pencil marks align.
3: bend to form a 90 degree bend and then measure from the back of the conduit to the end .
4: if your measurement is 305mm for instance then you need take 5mm off your pencil mark on the former and bend another piece to check you’ve got a 300 mm .
4:28 do you mean flanged couplers?
Meh sounds a bit boring to me. Top hat is a lot more exciting
