Re: Nikon S-ke fine focus (spur) gear

The problem will always reoccur on a nylon gear, the nylon shrinks over
time and the metal center doesn't, forcing the gear to split. However
it makes for a nice maintenance free gear system while it works.

The brass system will out live the nylon. Brass gears made hundreds of
years ago still work like they did when they were new, assuming they're
well made to start with.

So I suspect the difference will only be in the life of the gear. The
nylon may last a few decades, or if it's another plastic other than
nylon, may last a very long time.

Whether the rest of the system was designed to use the qualities of the
nylon gear for a better "feel", I'm not sure. I suppose it could, or
the nylon gear may have been choosen due to its lower price.

I'm not too sure about that, maybe someone else knows better.

Hello,

I have only heard this through other people, and have never confirmed
it myself, but I think I remember I. Miller Microscopes having either
replacement Nikon (nylon) gears or an interchangable brass version
available.

This was some time ago, so I don't know if they'd still have them or
even if it was ever true, but it's worth a try. Their website is:

http://www.imillermicroscopes.com/

.. from that link there should be a form to fill out describing the
part you're looking for.

HTH,

Kevin

Dunno if anyone saw my original post via News group.....

I just picked up a vintage Nikon L-Ke (model with 5 position dove-
tail
turret) that has the broken plastic fine focusing gear. It was
quite easy
to remove. Where can I find a replacement gear? What problems
would a
metal replacement cause (as I believe there are metal
replacements)? Thank
you.- Hide quoted text -

Would it make a difference whether it was nylon or brass?
