[Fot] TR-4 vertical link and trunnion

[Robert M. Lang]

Hi -

Call me stupid, but I have to ask this follow-up question... I believe the 
initial question was "are the new vertical links worth buying?". There 
were a tonne of responses to the effect of "when you swap in a used 
vertical link, check for... yadda yadda yadda.

I get that.

But I don't think the original question was ever actually answered.

Does that mean unequivocably that the new ones should be avoided?

I'll toss in anecdotal comments overheard from a certain materials science 
member of the list - that the new castings may be flawed (due to metalurgy 
and to casting methods), but that's the extent of anything that I know on 
this topic. Can anyone chime on on this with something other than 
"offshore stuff all sucks".

As a point of information, in the northeast where this is salt on the 
roads, all the cores that I've obtained over the years have rust along the 
area of the threaded portion of the link where it threads into the 
trunnion. As a semi-interested party in metal fatigue and so forth, I 
can't get myself to use any of these because I have no idea how bad the 
rust has penetrated - but I also know that the presence of corrosion can't 
be a good thing.

So, should "we" avoid the _new_ vertical links altogether?

regards,
rml
