No wonder the raw material was so expensive, Mike. Ron, if your prints call for 1.5", they're wrong. I have Larry Mac's beefed up (reinforcement ridge on the outboard side) bearings and I estimate they can be machined out of 3/4" material. I'd say the factory bearings could be made using a 3x6" piece of 1/2" stock.

The purpose of the extra height is to provide sufficient surface area for the Nyloil to generate enough lubrication for our application (as well as provide rudder centering). Are you using generic nylon that accepts 10+% water or Nyloil that takes on about 2.5% over its life? John, Thanks for reminding me why I am now leaning towards physics as opposed to aeronautics.

One thing i foud in the datasheet for Nyloil is that we must include a clearance ("shaft allowance") to prevent what you mention. Since that bearing does not really "work", i plan for less allowance than mandated (.003 or .004 instead of .009). I m sure that with Nylon 6, the clearance would be even more critical. -----Original Message----- From: "Sabrina" Sender: owner-zenith-list-server@matronics.com Subject: Zenith-List: Re: 601 XL bearing bloc material Michel, My flight school in Sarnia, Ontario used to have a 601HD (long before I started flying there).
