that is the chinese supplier I found. The australian supplier wrote the following regarding precision tolerance:
Asia tolerance standard g6(um): -5-14
Europe tolerance standard h6(um): 0-9
which made me think they might mean the same thing.

Owen, yeah that could be an idea. I did spot his site but didn't look further as he didn't have 8mm. However, I think I found the same rods from china in 8mm. But these say tolerance g6, is that the asian standard equivalent to h6 tolerance, or something different?
Well, if anything, I am learning more about steel rods than I ever thought I would need to know haha

Thanks for that, I just thought I could get away with something a bit cheaper. I didn't see any with high enough precision and specs on ebay, so if nothing else I'll get the ones snowygrouch suggested, but 140dollars ouch....
Otherwise the ones I was looking at, were these ones:
http://www.smallparts.com.au/store/item/sh08000x037500c1060/shaftinggroundprecisionchromesteel/
They are a bit cheaper, but still the same specs, I think.
-Diameter 8.000mm
-Length 375.0mm
-Straightness 0.0003 mm/mm
-Surface finish 0.25-0.4 um
-Hardness 60-63HRC
-Diameter tolerance -0.000/-0.009 (which i think is h6)
I was thinking if I get these I might not need to cut them down, as I lack proper equipment for this... or is that a bit of a gamble?

Hey everyone,
I've been wanting to do this mod for quite a while, but am having a bit of trouble finding a supplier for the shafts. I was looking at the ones snowygrouch suggested from conrad.de, but they charge 40euros to ship to australia, which is a bit steep considering the shafts are only 10.
The only local ones i have found that meet the specs are a bit overkill, costing around 50dollars each. Or maybe I just don't know where to look.
Someone suggested one of the rod sets from ultimachine, maybe this one:

I could get this while ordering some other things, but are they suitable?
So, If anyone could point me in the right direction, that would be fantastic...
Cheers,
Jacob

I suspected that might be the case snowygrouch...
Well, I went ahead and ordered the chinese rods. I thought I might as well try them in the event that they do work, before spending 140dollars on good ones.
Thanks for the help.
