Re: [ATM] How to Reduce Bearing Friction

["Scott Ewart" <scotte@frontiernet.net>]

Peter,
    The simplest way is to take some weight off the bearings by 
carrying some of it around the center bolt.  Add washers and/or Teflon 
slightly thicker than the rest of the bearings to cause the ground 
board to flex a little.  Adjust till you like the feel.  Too thick and 
the scope will start to feel bouncy.

Subject: [ATM] How to Reduce Bearing Friction


| Hi,
|
| I just completed a small Dob project and the AZ axis has too much 
friction.
| I used Ebony Star and Teflon matching the 15 lb/sq in as suggested.
|
| What is the simplest way to reduce the friction on this axis? I was
| considering doubling the surface area of the Teflon pads but I 
wanted to ask
| the group to make sure this is the correct action.
|
|
| Thank in advance.
