I still have conduit on my MPCNC, but I’m working on the beta low rider HW.
I was looking at steel online, and it’s $20 to ship anything (rigid tubes, duh), so I found a local metal place (a few actually), but I’m not actually sure what size I need. is 60″ enough? I need two pieces, right? Is the 0.049″ like the suggestions for the MPCNC important, because there seems to be a much more common 0.065″?January 10, 2017 at 4:26 pm #24649
I’m getting there. A new calculator soon.
.065″ is better for this. the 2 long tubes and 4 short ones for the z.

Glad I asked!January 19, 2017 at 7:20 pm #25480
Is 304 stainless what was used in the test machine?January 19, 2017 at 7:33 pm #25481
90% sure all of mine has been 316
one was from this test, https://www.vicious1.com/forum/topic/stainless-steel-quick-and-dirty-flex-test/
I bought it all a long time ago so I have the receipts filed away.January 19, 2017 at 7:51 pm #25482
The 316 should be superior as it has about twice the yield strength of the 304. However, it is also twice the price. I’ll play it safe and get the 316. It’s either $72 for two 8ft pieces of 304 or $147 for two 8ft pieces of 316 shipped from onlinemetals.com for me.
Edit: I forgot to apply the coupon code earlier. It was only $113 shipped.January 19, 2017 at 8:28 pm #25485
I don’t have easy access to them either but I will try and do a test as soon as possible.
That quick and dirty test is very easy and reliable for what we are doing with it.January 19, 2017 at 8:36 pm #25486
I bought some from a store in town, looks like a chain, “metal supermarket”? It cost $66 for 2 8′ pieces. I didn’t ask if it was 304/316…
It’s got some oil all over it. How should I finish it? Maybe just clean it and apply some poly-something-ane?January 19, 2017 at 8:43 pm #25488
It shouldn’t matter the physical properties we are concerned with are almost identical. 316 is just more salt resistant.
