Good question, to do this measure from the end to the back of bend, measure back from this point the dimension of the tray (this is your first bend). Now multiply the dimension of the trunking by square root of 2 (1.41) this will be the next bend. Maybe I will do a video on this to explain.

@@sparkyhelp3997 Your videos are amazing mate. Especially explaining the maths. But I have a question. Who taught you all this? I've never seen it done like this before on site.
@@timh5529 Hi had a very good apprenticeship in fact the person who taught me a lot was a guy called Tim (learnt a lot), the rest is picking up from other colleagues over the years, you never stop learning.

Hi Thanks for watching this is just a generic 45-45 bend if you wish to to back of bend see this: ruclips.net/video/JIWYFymGbwU/видео.html Thanks for watching please share with like minded and like and subscribe.
at 2min 25 seconds, you measure 50mm for the internal. I have been working with 300mm and 450mm tray using the equation you taught but adapted for whatever sized tray I am installing, but the internal bend keeps coming out wrong when i put it together. How do I correctly measure the internal for different sized trays please? (I have been fabricating 90 degree bends by doing two 45 degree bends because they are for armoured cables)

as an apprentice doing big industrial trays atm for over 6 months, ive been doing a lot of trial and error , not all equally good, this helps a lot :D

Some very helpful information here. But, how would I work at my starting point if I know where I want the middle of the return to be?

Wish you was my college tutor 😅 love the videos 🙏

how do you work out 45 degree centre to centres with this technique?
also does that equation work for other degree bends other than 45 degrees ?

Is the first line you’ve drawn the start of the first bend please? Also which line is back of bend please?

@@sparkyhelp3997 thank you that has answered my question. Subscribed 🙂
Hi,how did you get to the 41mm measurement? I've tried on my calculator but don't get that number! Thanks in advance
Hi as shown on the video X=tan(22.5)x100=41.421. Hope that helps please share with like minded people or even like and subscribe.
@@sparkyhelp3997 I wasn't using my calculator correctly. Thanks for the help!
@@TheCodboy19 How? Am not getting 41
When i make that calculation tan(22 5)x100, i get 55.7. Ive tried on a couple of different calculators. What have i missed!? 😂
Scratch that I used a Casio calculator and it come out the same sum. Weird how different calculators come out with different final sums.
Glad you worked it out, please share with like minded or maybe even like and subscribe.
