[ATM] need help with an altitude bearing problem
Hello Everyone -
I have a telescope that was made for me by a friend. The altitude
bearing surfaces are highly polished stainless steel against Teflon.
This results in extremely smooth motion with hardly any "stick-tion" at
all. This makes the scope very sensitive weight to changes at the ep and
difficult to counterbalance (ie, a counterweight that will keep the
scope from plunging downward when I add a 2" ep will also cause the
scope to swing toward the zenith once I pass the midpoint going
upwards). The bearing consists of an 8" diameter stainless steel "ring"
riding on 2 Teflon pads. I am trying to come up with something else to
use in place of the Teflon that would add a little drag to the system. I
was thinking of using a plastic that is maybe not so smooth as Teflon?
would pads made out of delrin or a similar hard plastic work? I have
been told the best solution would be to redesign the bearing assy
completely, but I have limited skills and even fewer tools. Any ideas
would be greatly appreciated.
Thanks -
RP "Patrick" Sutton
