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.
Same here but I was fortunate to pick up one for £75 from a job that had just finished in London. They were selling everything. Had to by a Stop End but got one from TLC for a tenner.
Well done guys! It’s so good to see training videos like this. New guys to the game have to learn and these old school engineering techniques are dying off. So many in the trade don’t know the basics. They only seem to know, “ twin N earth” Lol! I’m approaching retirement now and it’s wonderful to see this being taught properly! Thanks guys!
Literally spent so much time at work trying to do that but opposite way, it was really bugging me I just couldn’t quiet get it without cutting a bit off the end
Excellent video, I don’t do much conduit and really don’t like doing it but this video has shown the best practice to work out an elbow bend and actually makes it easier than the way I was taught
Hi Will. We are trying it’s just finding time to fit it all in. Hopefully we can do a back of bend to back of bend video soon. Thanks for the support Gaz 👍
My old mentor “Jurassic Sparks” Showed me this method (Hated conduit graveyards) Best method for me personally. Your the first conduit channel to show such Jedi secrecy. Now another thing Jurassic sparks liked doing was Pyro (MICC) without using a stripper and a potting Tool.
If you over bend it, you've got to throw away the conduit and start all over again 😂😂😂 Only joking... put the conduit back in vice bender with the conduit now pointing upwards, pull down ever so slightly and keep rechecking the 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
electrician154 now just to make marks on the former for different angles (part of the reason I like the American forming tool, however much lighter gauge)
I've been waiting for you to mate more conduit videos. Thank you, you have no idea how helpful these are. Do you have any similar techniques when bending in a bubble set?
Hi. Thanks for the support 👍. This one was an early video and shot live in the workshop but it maybe helpful ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-dTxEGvdd_38.html thanks again Gaz
Great vid as per usual. After using the set square couldn't you just measure from the start of the former to the mark. Then use this measurement from now on to get the back of the bend postion?
Great video guys but im hoping you'll cover the rest some day! Ive house bashed most of my life and I love to work with metal but there's so little UK videos on it. There's one were an "ole han" is teaching a class and he mentions several key numbers on how to cut to measure and fit perfectly. 1.5" through box diameter 32mm coupler 16mm one end threaded 6mm saddle That's all I remember but those who know will know... Some expert level videos on precision conduit work please!
I like to get a 90 and put it back into the former. With the arm in place, (as if to add more to the bend), I mark the side of the former where the swing arm intersects. This is then my reference point for future 90's
Great video. But can I please ask. If you put conduit in bender from opposite direction to bend due to length being too long do you have to alter any marks etc? Thanks
That’s great showing it that way guys but could you show us about how your doing it with a 3m length like you would on site please. Ie bending from bottom up and mark back distance please as would be very useful for new learners and apprentices. Thanks guys
good video, that looks a 20mm conduit, my question is: would the process be equal in a 25mm conduit? as i believe the bend is bigger in a 25mm conduit??
When I used to work on industrial sites, we used to use door frames to check our bends were 90 deg. It's been a while so I'm not sure if they still do it that way
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.
I’ve got a challenge. Now I’ve been doing Steel conduit for about 15 years the most difficult bend I found was forming pipe gradually around a circular shaped wall. In some cases a gradual circular bend using a full length.
That's called a concentric bend. You need to use the concentric formula to find degrees per bend and spacing between each bend. Using a protractor for accuracy and a charted Chicago bender or triple nickel to perform each small bend.
Been doing some practice using this method. Is there a reason it's always 10mm too short? Maybe bending machine set up? Also how would you approach it if you had to bend from the opposite way because your conduit is too long ?
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.
Back in the day I came from a single gang box, made a saddle over a dropping conduit and calculated what i needed to enter a wall mounted light fitting...i was chuffed...coupling right on the fitting....i would struggle to do that now ha ha
Very informative way to accurately bend galv conduit. I'm assuming the same principal could be applied with PVC? (Minus the bending machine) BTW, Nice use of a stray nail 👍
I hardly touch galv but great demonstration of the skill/feel involved in getting the correct angle with 'spring back' when bending (always gotta go past...but not too much'. Nice work Joe! (Oh ok...and Gary)
Hi awesome video as always.👍 I have a question but isn't related to the video but hopefully you could answer it. I've been offered an apprenticeship for a company that mainly works on power and BMS. I was wondering if I will still gain the knowledge of basic electrical systems. Cheers 😀
Hi JKW. Your college will only cover limited amount of installation practice... the key word you sent was apprenticeship they are difficult to gain so ask them what training they offer before making a rash decision about taking or not taking the offer. All the best Gaz 👍
Great refresher for me, love a bit of galv conduit work but I do mainly plastic nowadays. Even then it's getting rarer.. Shame, do they still use whale blubber to cut threads with? "Talon" I think it was called lol.. Showing my age! great vid guys 😎👍
Sorry gents. I’ve been doing pipework for thirty years and what you just done there is odd. Why use a scrap bit of pipe? Take your measurement to the back of the bend and subtract the dimension of the pipe. 20mm in your example. If I was going on an internal wall I’d allow 25mm for a distant saddle
Hi 👍. I did alive crank set back in the day sorry about the poor quality. Gaz ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-dTxEGvdd_38.html Thanks for commenting and watching 🙌
Welll what can I say, that is not the way to bend pipe mate, in the real world you just got to put a little too much in and take a little out l. I do like that you measure to the back of the bend👍 but that method is how I would bend to the front of the bend. 👍 all good if it works it works 👍
@@Jay369 you mean in reverse? These guys pulled the leave from up to down. Are you saying there is a way to pull the lever from the down to up position to bend conduit?
@@redx11x yes. If you look at the position of the bending machine at the beginning of the clip (approx 00:13), this is the resting position. You can feed a conduit into the bending machine and pull the swing arm upwards to bend long conduits. 👍
@@Jay369 Thanks Jordan, you've been great. I hired a machine from HSS and it bent the 4m conduit upwards just as you said. Thanks a million for your time and patience.
The way you bent that is a huge waste of time what is that 1/2” rigid? Get out your 3/4” bender, make your mark subtract for take up Use arrow put your level on the pipe, bend it, no need for all that lining up stuff you do, one measurement, deduct, mark bend. You do it as a waste of time
That's the way we used to do it , length required then subtract the fixed measurement ( cant remember now as this was in the 60/70s but something like 3 1/4" ) place on the bending mark , bobs your uncle , job done , this was in the days of foreman measuring how much work you had done during day .
@@GSHElectrical I know Gaz, no offence meant. I could train your lads to do it in half the time with the same result, after all when there out in the field time is important.
