Hi Jim, Well if you have good clearance and you had the bell crank galvanized
then you wont have any problems but it would be nice to see a cross section drawing
of what you are proposing. Are you following Kittredge drawings or is
this a Jim version. Hard to pass a comment without understanding the
situation but you don’t want them to rust together and find you cant turn
them when you need them. You can get away with a lot with good
maintenance but maybe Vance can say what works best in that situation.

tds.net Hi Hugh, These are not rotating shafts. They are rotating bel cranks
which actuate drop weight latches, front and rear thruster orientation and soft
ballast valves. Most only turn a 40 - 160 degrees. Thank you for any input. Best Regards, Jim K On Tue, Feb 2, 2010 at 3:25 PM, Hugh Fulton <hc.fulton@gmail.com> wrote: Hi Jim, I would be very careful about steel to
steel. What is the application? What speed are the shafts doing? If you do go steel on steel then you
need to have different hardness and very good grease lubrication. Slow rotation
is not so bad but if you can use bronze, Aluminium, white-metal or plastic
sleeves then go for it. Stainless on bronze no problem, Chs, Hugh From: owner-personal_submersibles@psubs.org

Hi
All, I've
not seen this before and am hoping for some expereinced people to help. I
am doing final assembly of some rotating shafts. Some are carbon steel inside
of carbon steel and some are Stainless shaft inside of bronze bushings. I
am not sure if never- seize or a good quality urea grease are better or
possibly something that I have not thought of! Thanks
in advance, Jim
