parallel extrusions

[evokanivo]

Hello,

I'm starting a design and haven't found a good way to join two extrusions in parallel. I want to join some 2080 with some 2040 makerslide (centered on the 2080). I think the simplest way would involve right-angle brackets with holes at 10mm offsets, but I couldn't find any on misumi. I thought about having misumi predrill horizontal holes, but that really moves the price and I don't think I can get the makerslide predrilled.

Looking down the extrusions lengthwise:

Anyway, your ideas/alternatives are appreciated.

Thanks

Misumi makes some angle brackets with one two or three holes in each leg. They are part numbers: HBLSS5, HBLST5, HBLST5 at $.68 , $.88, & $1.07 each. Or you could just drill some aluminum angle or the extrusions themselves.

Thanks, but the misumi drawings show that the holes are 10mm offset on one flange, and 15mm on the other. I've been trying to find 10mm on each side.

Yes, I could drill them myself, but that's what I'm trying to avoid. I don't have many tools at my disposal so I'm trying to do as much as I can with off-the-shelf parts. If I don't find an alternative I'll end up going that route.

I was always surprised they don't have a good solution to this. I made a chop saw guide out of extrusion and needed to solve a similar problem. I noticed that standard screw heads would probably interfere with each other on their brackets. You might need to countersink the holes. You could also try a wider bracket like HBLSD5 and drill your own hole in the middle on one leg.

They also make some three way corners that can work, but they are expensive ($5.50 each) HBLCR5
