Hi,
Thank you for your advise guys.
Ron, I do have experience stripping the arm, replacing bearings and cleaning it every once in a while. It actually isn't all that hard. I do agree that you have to have the right tools and access to a machine shop. it makes a big difference after you give it a good lube job.
I can get all bearings from the local hardware store but not the trunnions. Are they special parts made by Tiffen (they look the same as the trunnions in the Master arm). "Rig Engineering" doesn't really want to sell just parts for the arm.
Are there more leads ?
