Gus,

What is wrong with the design in the plans?

I am interested in learning what others have done with the metal to metal contact. It seems to me this design will wear fast and not be very smooth.

There should be no metal to metal, the strut rides in a nylon block bearing.

How old are your plans?

I think it is a ball bearing unit.

The bearing that the strut rides in is Nylon.

I understood that to be the bearing he was talking about.



The Nose Wheel bearing is a ball bearing.

I think he said "nose wheel strut" bearing.

yes a nylon block , thats what I have seen. My drawings are dated 09/01. Do the block specs include the "gear extended self centering ramps? Are drawings available for the nylon version? Thanks for the help.

The attached photo is actually from an HD (Larry McFarland's?) but the

design on my 701 looks the same and I'll be adding the nylon. Basically add

nylon plates with V notches inside and parallel to the aluminum angle.

Even the latest plans (7-L-1 dated 04/2006) show the V notch as bare

aluminum (7F8-6 dated 06/2005). I sent a picture in another message showing

how to add nylon V notches.

The pictures look good. I have some 1/4" Nylatron sheet stock, that should fit well. Thanks for the pictures.

In order to get full bearing contact I'm considering lathe turning two bushings  , these would require opening the 2" up to 2 1/4" on 7.F.8.4 ,7.F.8.5 and 7.F.7.4 . I would leave a flange on these bushings to allow bolting or riveting in place . They would also need a saw cut to allow them to fit over the nose gear strut assy. 7.L.1.1. My concern with the method in the photo is after the nylon wears a little , we will be back to metal on metal. What are your thoughts on this method ? Thanks Gus
