Strong Joint for frame

[Fuganater]

I'm no good with joining 2 pieces of mater together so I'm asking for more help.

I thought of 2 options to use. Here are my small models of my ideas.


Option 1
End to end. IDK if it has a joint name or not. Homemade L brackets to support.

Option 2
Miter joints for the top and bottom (or sides) and a straight piece for the other supports. Homemade L brackets to support.

Would one of these options work? Or should I do something else? It needs to be pretty sturdy with all the weight.

Cheers.

I'd say either of those would work as long as the L brackets are attached firmly.

What kind of material is it?
I'd recommend welding if it's metal. If welding isn't an option I'd go with the method in the last picture.

^^me too.

1/8" think Aluminum. The L brackets are 3/16" thick Aluminum. I can't weld because I don't have the tools. And a welder is just too much money for 1 mod.

/\ What he said. Drill through the L-brackets and tap the holes in the posts. That should give you a good connection.

OK, and I can understand that you don't wan't to hire a welder. As x88x said, the brackets should be fine. But if you ever have the chance to learn how to weld take it. It's a lot of fun

Hire a welder?? LOL where the heck am I gonna find one of those in the middle of freaking Africa lol.

You obviously have the knack for proper mechanical fit, Fuganater ... a talent that some of the welders at my work have never mastered.

An alternative to welding is brazing ... think of it as high-temperature soldering. Any old torch or even a manly soldering gun will work well enough for small jobs. Although I'm not at all certain whether aluminum metals can be brazed like copper-alloys and soft metals.

Another alternative is chemical adhesive. Do not underestimate the power of Loctite. Then again, do not depend on adhesives for load- or stress-bearing applications. If you do choose a bonding agent then cleaning/degreasing and perhaps some surface abrasion will go a long way.

I ordered some JBweld.... was going to see if that worked well or not.
