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.
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!

I’m very new to this realm and love to learn of it. Your comment sparked a question Tom. Why never a 45? Because of difficulty level or strength? Thanks!
Thanks! #2 and #3 look less problematic for sure.

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.

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

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

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 .

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

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 жыл бұрын
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)

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.

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.

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

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.

@@TheMetalFabGuy can be used for other degrees, just divide the angle you need by two and then trace each one.
Now part 2, I do not do !! Can’t stand cutting with grinders. Just to risky
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

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.
I always do a 45 for an outside corner, only cope for the inside joint

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

how to smooth the inner part
@thardyryll
Жыл бұрын
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.
