ok, so here is some progress and a teaser...
made some bearing cups out of 3/4" INTERNALLY THREADED pipe coupling, got two out of each 6" piece with enough left over to work with for cutting purposes, then drilled out the inside using a step-up bit to 7/8" inner diameter...
and here is the drawn plan for the rockers... based on the harley springer design...

here's the gloves I'd made and never delivered on the photos, the vintage gloves from 1915 are on the left, the ones I made are on the right...here as well is a shot of the porch-swing spring with the ends flattened for the springer purpose...

ok, FINALLY SOME PROGRESS...work has been kickin my butt, and its been REAL HARD to get motivated for anything besides sleep and cartoons....
so, first up are the rockers...cut from 1/4"x1 1/2" bar stock, then clamped together and drilled for dropout and whole saw used for bearing cup positions..
THE SECOND photo shows how the rockers were shaped to allow for maximum travel, should I hit any of the florida gators while cruising at top speed...

then, once everything was drilled out and dropouts carved to completion, I welded in the bearing cups.
this was done by placing the rockers on a flat NEW sheet of metal, to avoid any high low spots and simply lined up before tacking, and then fully welding in...
and VOOOALAH: FANCY SCHMANCY SPRINGER FORKS...

Great write-up and pics, half!
Tnx a lot!
I think oilite bushings might have been btr and cheaper, especially with the actual spin rate and distance of travel involved.
I also think some sort of small spring, or at least a compressable rubber bushing at the top of the spring stack will be useful for when the front axle unloads.
When the front end lifts, or wheel drops, it's gonna ker-chunk!
Really annoying with a springer! lol
and if you don't incorporate some sort of dampening you will have a lot of fun learning abt springer pogo stick action.
I do know people who got pretty well banged up and mangled some nice looking harleys when they encountered a washboard surface in a turn, riding a hardtail frame with a springer front end. At the speed they were travelling it just hopped them right off the road.

Look closely, and you will see the rubber dampener at the top!
And, I didn't find a nice return spring until everything was pretty well put together, else I WOULD'VE used that...however, it would've required a taller post, or shorter main-load spring...
As for washboard, don't really get a lot of that here, just a couple of real doozies of potholes...so, I figure between the springer front, and sprung seat, I SHOULD be alright..?!?
Seems to work fine for a China girl, the added power and speed of the 4-strokes may change my mind, I figure I'm already 60*/. Safer not riding drunk anymore! (Used to b pretty bad about that
)

Oh, and as far as bushings/bearings debate; I wanted the ultra smooth action of the bearing, with the added benefit of NO side to side wobbly action...
And from my skateboarding experience, these can put up w/a HECK OF A LOT OF ABUSE!!!

Soon you will be the resident Xpert, half!
All I know is what I've seen. Never personally owned a mc with a springer installed on it. bought and sold quite a few, though, and seen quite a few run on friends bikes.
Your thread has been great and I'll look forward to the reports you will post on your travels.
Oh, I forgot to ask if you made any considerations of trail when you were doing your setup. It will make significant difference in handling.
Rake and trail... interesting subject for study... frame geometry does funny things.
Oh, btw, when you don't drink, and DO tumble, it hurts right away, and not just later. Been there, done that.

this will be the third set of homemade springers I've built, and going back to the first rocker design.
It is based on a simple Harley sportster springer front end, the forward linkage provides easy cushion
And stable riding. When the spring compresses, it sends the frame down and slightly forward, giving a low center of gravity, and have only ever had it get squirly when trying to maneuver turns at speeds I should never be attempting in the first place...

Did you just call me HALF A MAN?!? ...WHY, I OUGHTA.... LOL.
YEAH, THE DRANK SHO MADE IT EASY TO FALL, JUST TOO BAD IT MADE IT EASY TO FALL...IF YAH CATCH MY MEANING...
PLUS, I have my first son on the way, and want to set a better example for him than I would've previously.
