How to Make a Flat 90 Degree Bend in 75 x 75 Steel Trunking using 3 cutting methods

- I form a 90 degree flat bend in 75mm trunking using a hacksaw, jigsaw, angle grinder, rivet tool, file, square and tape measure.
Following the guide in the city and guilds training manual but with some onsite practical application.
The idea is to show the different ways we can achieve the same goal and how that might help us out on site.
Plus its the first stage in the exciting booth build!
The awesome video from Gary Hayers and Marus can be seen here • How to Make a Flat Ben...
My own method is shown here on 100 x 100 trunking • Fabricate 100x100 Stee...
Great job 🫡
Great video. A lot of the sites I work on, use of the angle grinder is classed as 'hot works' so there are more permits and safeguards involved than using jigsaws / hacksaws. If it is just a small installation, it is often quicker and easier to do the work without the grinder.
Nice video Mark
On the back edge of the piece your folding score it with a few passes of a scribe and it gives the metal a point to fold at and you will end up with a nice square clean corner on the fold. And also where you overlap the 2back side cut one side off at 45' and it gives the look of a mitred finish
Good call on the scribe! I was careful to follow the guide in the college book in terms of the cuts. I usually mitre both angles in the back so they meet on my own cuts. Thanks for the input, the more ideas and chat on this the better. Awesome
Can't beat buying a manufactured angle from the wholesalers
As mentioned in the video that wasn't possible and sometimes isn't. Was an issue for a while in the global supply chain. Knowing how to make your own is no bad thing.
Good
How many times did you try and blow the swarf away with the face shield on? 🤣
Hello
I need to do external bend 90 have no idea how do you have a vid on it or can explain how to do it thanks appreciate the vid
Excellent tutorial. I haven’t used Galv trunking for about 10 years. They don’t use it in Aussie.
Thanks, I miss making my own cuts tbh. I still think it's more cost effective to make. But what do I know lol.
