Good video lads. I rarely get to use my (very expensive) conduit bender in my mainly domestic world which is a bit of a shame as a tidy galvo job can be rather satisfying.

One of the vice benders I used to use, had a special type of former where you could bend 90 and 45 deg bends without having to check it after. Whatever angle to set the former to, it wouldn't allow you pull more than that angle.

A better tip so you dont have to mess about with a scrap bit of conduit is (for 20mm conduit) take a 100mm off any measurement you make and put that mark in at the start of the former , its a lot quicker

electrician154 I was about to comment that once you have the 90 degrees, measurement, you can measure that distance between the start of the former, take that measurement of the bend amount and then don't have to worry with a square and scrap piece when in the bending machine as it's a consistent measurement

Love these conduit videos. Lots more needing covered on conduit as I'm no expert with it myself. I seen a really old video of an older lecturer teaching young lads how to do it. He used certain numbers to calculate exact installations which was very impressive. He took into account the depth of the saddle, couplers and through boxes etc E.g Saddle -6 Depth to center of through box 1.5 inches Coupler 16mm 32mm for running couplers I think it was. So adding or subtracting those figures where needed. It was pretty accurate stuff. Any info or videos on this type of exact measured installs would be great

I'm an American electrician apprentice and I run ALOT of emt. Like I've never seen anyone ever lay a 90 like that or physically bend it like that. Is the process the same in mm as in inch? So like that looks like 3/4" emt which has a "take up" of 6" so if you measure to the front, back, or center of your pipes (it depends on how the pipe is positioned already what's what, ultimately.) from your destination to start points. So if you need a to make a corner in a room and your last pipe is 51" from the corner, you have a 51" 90°. Then you subtract 6 from that. Then you hook the bender at the 45" mark. Bend, level, tweak.

@Chequr_Prostate 2 жыл бұрын

If you turn the conduit the other way around and parallel to the floor, then put your tape measure under the conduit and push it in as far as it will go into the former adjusting the conduit until it measures 300 on your tape, then make the bend. The bend will be 300mm to the back. The only thing that will throw the measurement out will be the size of the lip on the end of your tape. But you can adjust to your tape and it will bend correctly every time. Use the same method if you are bending upwards in the vice.
