Newbie- Joints to fit ALU

[tcdk]

Hi

Im starting to plan building my own CNC router.

I have access to about 250 meter ALU profiles in different shapes, dimensions etc.

Im thinking in building the frame in 100x30mm (3mm thick) and 50x50mm (3mm thick)

I will have to make some sort of couplers/assembels, that I can router out with a Copy router for alu (old but good machine)

Im thinking in making it something like this, and make threaded holes.
I will use largeheaded umbraco-bolts.

It will look something like this:



The machine should be used to wood and plastic, but ALU would also be nice.
The dimensions on the cutting area, should be around 800x1200mm

Will the ALU profiles I have be "strong" enough for this?


If there are any words you don't understand, please let me know. It's not always easy to find the right word when translating

Because I have the other alu-profiles for free.
