Re: [Frame] Headtube bushings

right you are, My idea was for a tube with bushings on each end and a grease
nipple in the middle to load the centre section with grease lubricant. My
research shows that there are several sintered bronze options that have very
little friction if used properly. the idea is for the mount ('C' shaped
section) with the 'top hat' style bushings inserted from the insides of the
mount. The tube should fit with little clearance unside the bushed mount and
a long bolt to hold the assembly together. The axle is to attach to the side
of the pivoting tube at the required angle.
If this still needs claification I can illustrate and mail the concept
sketches to whomever wants...

Although you might be able to use bushings for control rods and steering
linkage, there is too much friction in a bushing for head tube usage.

Maybe if you supply more info the list could supply more help.
