Aluminum t-slot deflection

[Gp!]

Sitting in the hospital thinking about hanging equipment. I don't have access to a computer at the moment.

Does anyone have deflection numbers for any of the t-slot profiles.

For example, a 5' length of 4 way x 1" t-slot. What weight causes 1/8" bend. 1/4" bend. Etc or anything similar.

Thanks!

I think if you go online to the t slot catelog there is a page that gives you that info. I will see if I can find a link.

Here's the one I use for all my 80/20 (T-Slot Aluminum) projects.

Thanks that calculator tells me exactly what I'm looking for

@Gp! I am curious what you ended up going with? What deflection and why?

I went with 1010.

These were for sliding equipment racks - mainly lights and sump stuff. That is a standard size that let me reuse tooling and hardware I use for other things.

I ended up checking deflection against cad models but it was minimal for my needs. The 1515 profile would have been stronger but this is mainly cosmetic - more than an 1/8" is usually visible for lots of people.

If it was for levelling a tank stand I would have wanted at least 1/16" or 1/32" so that the tolerance of the level was the weakest link.

Thank you for your reply! That helps.

I'm thinking of using this stuff, it says its 5x stronger than aluminum, and it doesn't conduct electricity.
