Proxxon FF500 x-axis nut bronze or brass?

[@claeswikberg8958]

hydrochloric test was real clear! wierd that Proxxon would use brass instead of bronze...

[@johnsherborne3245]

Sadly there are few folk who should know better that don’t know the difference!

As mentioned in the repair video and quite important for Proxon; are you the first owner? And second; why did the softer nut wear your spindle out so much compared to the harder bronze? If Proxon made the nut the guy or girl in the storage area probably thought that all yellow material is bronze... Probably on a Monday. No excuse, but shit also happens everywhere ;-P Best! Job

Yes, shit happens.. 😕 I suspect that a very rough cut threading played a role in this. Also see my reply to you other comment.

And with that Proxxon sadly lost its sheen.

😕 I'm afraid you're right..
