Build your own springer fork!

When we talk about springer front forks, there's always the question about what
springs. Yeah we can use valve springs off cylinder heads or go to the hardware
store and find some cadnium plated things from their assortment to build with.
Neat forks hugh ?
But the springs on these double acting springer forks will likely be "compression" springs
which have space between the coils.
Check this link out which explains coil springs.

This link is to a supplier who can make custom stuff.
W.B. Jones Spring Company:springs manufacturer, coil, compression, torsion, extension springs
Look at springer forks like the Monark bicycle forks which use tapered ends and some
others where the coil spring has somewhat a barrel profile. The springs will be part of the eye
appeal and a focus area to the look of the forkset. Consider this when selecting your springs
expecially if you are considering a Boardtrack or Vintage build. But remember whether you use
chromium plated springs or painted ones, they will be a center of focus with those checking
your bike out. (judges at contest events too)

Somebody from Australia made a nice e-trike , with a homade set of these. I can't find the post anywhere I believe his name was Aussie Jester. It was one sweet ride anybody got a link?
Heres a utube link YouTube - 48 volt 20ah Electric Trike YouTube - Custom 48volt Electric Trike Overview Living life large from a wheel chair!!!!!!
I watched his builds and he is a true craftsman!!! He built his own front end as per those instructions and than modded them for his own taste as he thought they were inadequate for his application. In the end KIM'S conclusion was he would not build another, and just buy one as the hassel, cost, and time did did not justify the end result...POPS

I'm in the process of building one of these to go on an old Simplex I modified. The tubing is Expensive now.
If You deceide to build them...I got some extra springs and freeze plugs that the plans call for.
Cheers

I have the big lower springs but don't know what to use for the rebound springs since this is a bit heaver than a bicycle.? I have all of the pieces made and stone tumbled ( looks pro built)LOL.
I had seen the link in the past and was very impressed. Didn't ever get around to building one ( for my OCC). However this is what I had planed to do. Take my existing fork tubes, rotate them 180Deg. This puts the brakes to the rear and will not interfear with the spring tubes.
The bars that the wheel mounts on would be offset around the outside of the tubes. These are just basic sketches of what I was thinking.
