Upon considering all these options, really, I think it's clear that the best one is
drilling the hole and inserting the pin.
The benefits:
- a mechanical block against that shaft ever twisting inside the tube
- it can be drilled and inserted AFTER I get the wheels all glued up, some test rods on, check them for quarter so that I
know for sure it's right, before I anchor it in there with the pin and more Loctite.
I can't stress that second point strongly enough. Yes, I have a jig for assembling these wheelsets. And yes, they
look really good to my eye (as far as being quartered the same). But I won't really
believe it until I have 3 drivers going round and round with rods on them and no "jammy" spots.
So I would feel much safer having an "out" where the axles are "pretty tight in there", but could be twisted apart
if I really need to adjust them.
So while I wire-locked one axle, I won't be doing that to the others until I can test this thing with rods.
I don't think knurling or copper plating would be anything other than harder and less sure solutions.
Even if copper plating worked better, I would still rather have that locking pin in there.
This is all the long way of saying that this project is involved enough without me searching for other solutions
when I've found a really good one, so I'm settled on how I am fixing these wheels to the tubes now,
and I am going to focus on the tender to get me over the electrical pickup hump.
