I recently stripped and regreased all moving parts with a spray-on teflon lubricant... seems to work fine but am a little worried that I should has used a different product... any advice, Brian?


Thanks again for sharing.

David,

Here's what I use on all my vintage mounts. It's expensive but an outstanding performer - even in very cold weather:


Dow Corning Molykote

john,
they are both unitron mounts.
the mods to slow motion were done by previous owner
so he could put cables instead of knobs.
must have had short arms.
pretty sure this was unitron 144 mount if i remember right.
i think these were used on brandon 3 & 4" scopes and
also polarex /unitron 3" and i think i saw a picture of
a 3" folded on one of these also.
as for weights i think you just have same mount
made for 2 different scopes.
can you take a picture of one of those mounts next to
a 140 mount without the weight and shaft.
my picture above might not be a good representation
as it is my 1954 worm drive mount and newer mounts
dont have hollowed out parts like that one.

Brian

they look close except beefier spring's that would
hold more weight and non rounded base.shows you lots of changes over the years
if you look close but still have that classic unitron
no mistake look.
anyway i think one on right was called 144 and made for
mostly for European market.(polarex)
thanks john.

Thanks Brian and John for the heads up on proven lubricants.... as usual you are both very helpful, patient and willing to share ... much appreciated.

Nice Unitron collection, too, John.

Cheers
David
