Thanks Derek, very informative & it’s always good to see how others do it. 44 years in the Trade & I’ve always used the ‘measure back’ method for 90’s. Generally for most UK bending machines the measure back(that you showed lately in the video) is 70mm for 15mm tube & 100mm for 22mm tube, but it does depend on the former radius. Easy to remember, fast & with limited tools. As you know, limited equipment on-site, no vice or Square, so a door frame is perfect for checking for a 90. A pencil too, is better - less marks on the tube. Thanks mate, very informative👍
Great video. I bought a cheapish pipe bender, I'm not a plumber, it was just for some jobs at home. It was crap, when I pulled the arm to create my bend the arm coming down would move slightly to the left so all my bends weren't straight to the rest of the pipe, especially on 22mm. The arm had slight sideways play on the through bolt, I'm waffling but my point is don't buy cheap coz you will buy twice, I wasted time ,money and copper pipe, buy a decent bender folks.
Great tutorial, thanks. I'd watched a couple of shorter videos before this, and wondered what a 21 minute video would teach me that they hadn't. Turned out it was quite a lot!
Thanks Derek that was an amazing video, the way you've explained it the 2 different ways is brilliant, after todays pipe bending exercise with Liam which was really good, but after watching your video its makes it even more easier to understand. Liam was saying watch Derek's video as he loves doing the precise measuring but to be honest it just makes it so much simpler when you make these videos to understand the proper method of how to do it. Thanks Derek much appreciated for doing these video's. It will help me now with a better understanding for day 2 with pipe bending at tomkat tomorrow.
Many thanks Derek great video. Found my pipe benders chewed side of pipe as the guide piece not staying square. Solved by putting square on to ground with small wood block so I can use one handed, leaving other hand to hold the guide square. Easier as well if your strength is poor. Part 2 now.
Thanks for your excellent video on how to bend pipe, Derek. I appreciate the close ups and angles that your camera man (or woman) went to the trouble of making. Here in the States, residential copper installs are normally done w/o pipe bending and instead 90 deg elbows and T fittings are used. Obviously you have much better laminar flow inside the pipe when you use a pipe bender instead of fittings.
I was taught when bending copper 90 degree angles you add on half the pipe diameter. For iron you take away the whole pipe diameter. * Therefore, I bend my first 90 by marking 157mm in this case ( that’s the 150mm plus half the 15mm tube, I use 7mm for this). * I use the set square just like you did to line up my 157 mark against the INSIDE of the former. * Now pull the bend * Next put the pipe on a flat surface * Put a spirit level on the floor by the side of the original start of the pipe, to the 90 bend I just did * My next required measurement is 150mm ( centre to centre ) so by measuring from the spirit level and mark the pipe you’ve accurately added half the pipe diameter without the faff of using a set square or ruler to mark the centre of the pipe * Put back in machine and again, use set square to line up the second mark to the INSIDE of the former * check everything is square and pull second bend. * It’ll be 150mm centre to centre.
Also dirty formers grip the pipe and cause rippling . wire brush on a drill and get them nice a shiny helps a lot allowing the pipe to bend smoothly . also bit of WD on the roller bolts
Really good! Only after watching this video I have learnt how to make use of a set square when pipe bending to get ACCURATE measured bends. Absolute genius. Never have I seen it being used and never have I been advised of using it for this purpose. Also, using a loose piece of pipe to get the centre I found very interesting. Magic. Definitely giving this a go soon. One question. On the former, you sometimes notice marked lines. What angles are the these marked at? Thanks Derek 👍🏻 Asian Jon. Training.
Hi, does anyone know how to bend flat copper pipes? I understand I'd have to stuff the flat copper pipes with, like, fine sand so that kinks won't form when bending. But is there a specific tool to bend flat copper pipes with?
Enjoyed the insightful video on how to bend copper using a manual copper bender. In the States, I often find techs using compact bender kits like that of Hilmor. What are your thoughts about the Hilmor Compact Bend Kit? What are its strengths and weaknesses compared to the manual bender used in your video?
I have never used or even seen the hilmor compact before. I don’t even know if we have them in the U.K. I will do a bit of digging and hopefully let you know with a video 👍🏻
@@tomkatgastraining Here is a video I found on RU-vid with a brief overview of the Hilmor Compact Bender Kit. ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-5Niyp6u9MCM.html
