I remember doing these 90 degree bends. My old tutor would insist we rivited the overlaps together and I hated it as they would stick into the trunking where the cables go, reversed nut and bolts like this is a much cleaner and more suitable job IMO. 👍 We also had the steel blocks in the trunking - which would always put the footwear to the test when it fell on your foot.
This is so much easier than what they are trying to get us to do at college!! Thank you lads!! I’m onto my 10 hour assessment after Christmas so this is a god send thanks again!! Matt
Great video. Fantastic resource for students on the C&G course, the text book looks interesting too, can see a new addition to my library as a reference resource. Hope you enjoyed your half day practical 😉👍
10:56 wish theyd taught us this way at my college. Learnt this the other week and it was a nightmare trying to use the hacksaw to cut the flaps. They never once suggested we should file it but ill be doing that from now on haha
Having done 100s of metres of trunking could you try doing this bend without a vice ,also if tap the corner with hammer and small chisel you will find it easier to bend.
Good idea to use off cut of trunking to make B&C marks as long as it is square sometimes open side cut be squeezed in a bit so I would check with a square after
By doing the trucking to the left, when facing the open part of the trucking, isnt the bend actually going to be to the right as the opening side will face the wall? Fantastic video by the way.
Quick question - do you always need a pilot hole when working with metal or is it an option (i.e. easier/leads to a better finish)? This video has been helpful! Thank you. Regards.
Is Marcus still one of your students or has he come back to help teach? I remember him from the electrical tests after a fuse board upgrade video, not a lot of hemming and hawing when it came to answering your questions!
Hi Gaz interesting to see how its done and thanks to Marcus he must be one of your star pupils! But would you really do this in industry it seems like a waste of time and would be expensive if you are charging by the hour. Isn't it easier just to buy a ready made galvanized 90 degree 50x50 corner piece? Why does City & Guilds expect you learn something you are never likely going to have to use. Regards
90 degree maybe, but if you need a double set in a tight space, say 2 sets of 30 degrees each, then occasionally you may have to know how to form bends. It's a good skill to have.
Took me three goes today kept on getting one thing wrong each time. Luckily my assessment is next week. Either cut the wrong line or drilled holes on the wrong side like an idiot but i feel like i could do it in no time now
All those wonderful materials the UK has for let's say to catagorize it, Industrial installs are simply awesome, I loved my time working with MICC, SWA, Tray and trucking and making off board distribution panels. I wasn't a big lover of the UK domestic scene and hated bungalows all that rockwool and dust. Yuckie
instead of putting nuts and bolts like you're gonna make london bridge and making all that fuss cutting them you could just put small rivets much easier and much cheaper
someone wanna answer these for me What is the measurement of trunking they require vertically? Besides the tools in the box what other tools and equipment does he require? What is the block of wood used for? When he marks the 450mm at point A he says it’s a critical measurement because it’s the…..? Which way does he send his trunking to the left or the right? What does he use to measure lines B and C? When he cuts line A how many sides of the trunking does he cut? After placing the trunking in the vice but before he cuts line A what does he do? What does he suggest you also wear while in the workshop? What does he say is the biggest failing of students when cutting line A? When cutting line B what does he do to the back section? After removing the section between A and B what part does he remove next? How much of the return lip on the other side does he cut out? When he places the trunking in the vice to cut the inside line A to Cwhat does he do to make it easier to cut the inside? After cutting all the edges what does he do next? With all the cutting and filing what does he need to do to the surface of the trunking? After forming the bend what two things does he check before drilling the holes? When drilling holes for the nuts and bolts what size drill bits does he use? After inserting the nuts and bolts, then cutting them to length what does he do then? What two things does he not fit at the end because he wants to re-visit them in a later presentation?
Google this The City & Guilds Textbook: Book 1 Electrical Installations for the Level 3 Apprenticeship (5357), Level 2 Technical Certificate (8202) & Level 2 Diploma (2365) (City & Guilds Textbooks) Gaz 👍
great video! though its a silly assessment from c and g esp when you can use pre-made 90d ones, work smart not hard! yes teach the theory but no point spending ages making a bend like that as an assessment imo
Ugh, not good. I've been doing this sort of thing for over 40 years and my bends are simpler and much better looking than that. They are also quicker. Try doing that with multi-compartmented trunking. Also, on site, when bends have to be made there's never a vice around. I suppose it's a dying art, now electricians never have to cut their own bends, they just order manufactured ones. The trouble comes when you need a unique double set in a piece of trunking, or some such, all that palaver would never work.
@@GSHElectrical Fair comment, it just seems terribly convoluted, specially when out on site there's usually limited access to vices, unless you drag a plastic bench round with you. I'm in this poxy lockdown again now, but maybe one day I could send you some pic's of how I do it, just stuff I've learned over the years. Also-I'm not trying to be a clever dick (there's enough around already) or disrespect what you're doing.😉
