Alternative Spring Rod Bushing!


It all began when I was intrigued with the springer front end and saw how most builders were handling the spring rod bushing in the spring perch.

To buy an oversize bushing that required special machining of the perch plate, it worked , but I wanted something different that worked a little better for the control of the rod movement. I came across HEIM JOINTS, the ones you can get from MCMASTER-CARR with .500 inch spherical i.d. and .50" width and about 1 inch or 1.25 inch o.d., drilled standard 1.25" hole in the perch plate and then added extra tapped holes to secure a spring capture/bearing plate.

Man, so far so good. the rod does not bend as it travels and less noise.

This is done at a rake of 38 degrees with springs and other parts from 45restoration company. 21 inch front wheel, 200 x 16 rear, frame is 1.25 od x .120, with an evo and a 5 speed. All chain drive. And not finished yet. I believe in riding the "mock up" to get the bugs out.

More experiments are due...

Anyone see long term problems with this setup in the springer bushing?

Good work! If you speak a springer oversizing? No flaming or bend ... should I even made ​​0.120 thick 1 " springer and girder and no flames on road at 140 km / h ...

Anyway I like the work you describe, you can upload photos?
