25mm stainless tube

I have the 23mm looking to build a bigger 25mm stainless tube router.
what wall thickness. I live in Portland Oregon anyone know of a good place to buy other then ebay or amizon ?

Amazon gets it pretty cheap sometimes with free prime shipping I got it cheaper than my local shop.

Someone in another thread mentioned Speedy Metals
and they’re definitely the cheapest I’ve been able to find. For whatever reason, the .065 wall tubing is 1/2 the price of the .049, so that’s what I went with.
Tubing for a 24"x36" machine was $100.60 including tax and shipping to Detroit.

Edit to add: This tubing is tough! Don’t try and de-burr it with an emt deburring tool, it’ll get eaten…
I had to use the grinder and a file to get it nice and clean.
