I'm glad you can't hear me yelling on #2 to just cut the dam thing !!! Thanks for the video !!

Tired to do method #1 by myself but couldn't figure it out. Thanks to the vid now I know.

Great stuff. I always cope, never 45. Thanks for an awesome video!

Method 2 worked a treat for me. Easy to cut it out. Easy to weld it up and turned out nice and square. No more 45 degree mitre cuts for me!

@danburch9989 11 месяцев назад

The 45 is more pleasing to the eye for exposed joints but has 80% of the strength that the inside & outside coping joints have due to a shorter weld bead. Weld beads are usually stonger than the parent metal.

@robertsonplantwalls 10 месяцев назад

this. people forget the metal used for welding is very pure and has incredible strength. More weld is a better for strength.

@stevev6384 3 года назад

I do 45 cuts way differently. Coping is what I do when I’m joining regular mill scale covered angle iron. . But when I want it to look nice like if I’m tiging some stainless for a frame. I always go with 45

@TheMetalFabGuy 3 года назад

Thanks for your comments and watching Steve. 👍

@CamiloSantana 2 года назад

ahhh! beginner hobbyist here building a shelf that wishes he saw this a few days ago. trying to do 45s with a chop saw I've learned is a crap shoot. I don't have a band saw. angle grinder doing either of the copes would've been better. I'll do better next time. thanks to you

@TheMetalFabGuy 2 года назад

And Thanks to you for watching Camilo. Instead of the Cope or mitres anther option would have been a square cut but to have sat the angle inside each other, like you see commonly on a gallows bracket. Plenty of options... Good luck with your project .

Is any one of them structurally stronger than the other one? Which one is your preferred method if not specified by the drawing?

@TheMetalFabGuy 3 года назад

Thanks for watching Bob. Unsure with regard to the structural strength but would imagine all 3 would be more than adequate in the smaller range of material ie 2”’as per video. Personally I Would usually go for mitred option on framework. Though both methods 2&3 allow for simple square cuts on 2 sides of a frame opposed to a mitred joint being required on every end. Method 3 as the video briefly shows, can also be used as an option for a mid bar on a frame. (Where I slid it into position)

@bobt5002 3 года назад

@@TheMetalFabGuy thanks so much for your explanation.

@TheMetalFabGuy 3 года назад

With consideration, I’d suggest that the mitred joint is the weaker of the 3. More joint to weld with the other 2 and the mitred joint has only the one axis of weld. But only my suggestion and I’m sure there’s a calculation out there somewhere to prove that.

@HailMich Год назад

Most saw machines I run cut 45 angles without the extra effort. Just type 45 and go… but honestly I’ve never saw someone cut with that little of coolant.

@TheMetalFabGuy Год назад

Thanks for watching Eric 👍 “Type 45”. That’s some saw you have. Look forward to your video. Sometimes I cut without any coolant 🤫

@HailMich Год назад

@@TheMetalFabGuy hydmech or hem saw are what I usually run. I do like the video. I saw a lot of steel with angles,channels,flats, and I beams that are fabricated by companies who have us saw there kits. 55-100 pcs.

@IzarySulz Год назад

Hi, what machine are you using to cut the steel?

@TheMetalFabGuy Год назад

Bandsaw for the cut to size. Angle grinder to notch.

@versatileduplicity9313 3 года назад

Now part 2, I do not do !! Can’t stand cutting with grinders. Just to risky

@xXTECHxKNIGHTXx 2 года назад

So say you are trying to make it out of a single piece to make a shelf, couldn't you cut two opposing 45s, then cut a relief in the steel and bend the angle to make a right angle?

@TheMetalFabGuy 2 года назад

Sure can. Good option for a 90 👍

@AndresAlvarez-cp2he Год назад

Yes, by far the easiest option if you have a long piece, just make sure you leave an extra mm to be filed away if necessary for a perfect fit.

@AndresAlvarez-cp2he Год назад

@@TheMetalFabGuy can be used for other degrees, just divide the angle you need by two and then trace each one.

@nateb4543 Год назад

Maybe it introduces more ways to mess it up, but couldn't you cut a 90° notch out of 1 piece, on one side, then bend it to make 2 45° like the first method? Less cutting, less welding, maybe a little hammering. For the other methods, i was thinking if instead of removing the notch, you ground it down (thickness) and the other piece and have them overlap, then weld? You'd have a buldge but it might be stronger? Idk, new to all this, just spitballin

@techwizpc4484 Год назад

You could do that but be sure to bend well because the curve where it was bent adds a few millimeters and can easily mess up the 90 degrees. I had to resort to just using the first method in this video.

@haerulrijal Год назад

how to smooth the inner part

@thardyryll Год назад

That is always difficult because an angle grinder with a flap sanding disk cannot reach all the way into a miter cut. The two coped 90s are easier to smooth. There are narrow hand-held belt sanders for close quarter sanding in tight spaces, but they are a specialized tool.

@Schrodj1 Год назад

I could use some help. Even with a square guide I'm never getting perfect 90 squares using 45 cuts on aluminum... I figure it can't be heat, but I'm losing my mind trying (and failing) to get square corners here. Any advice? Are 45s too hard for the layman fabricator?

@TheMetalFabGuy Год назад

Once you’ve welded the 45°s or before ? Sounds silly but make sure your square is actually square to begin with.

@joanv8190 6 месяцев назад
