I finished up the springs using a hacksaw to shorten the 2 bolts. I get less than two inches of travel when I jump on the bike, so no stops are needed, plenty of space. The springs are compressed about an inch as it is set up, so they don't move left or right. Even if they shift a little, the stability is unaffected, the bolts keep it aligned.

One of your keys to the great results you are getting, besides design, are those thick custom brackets. A nice solid platform to control the lateral flex.

You are really dialing in this home made suspension thing, WC.

I'm lucky that I can have them all made up cheaply. 5mm steel custom cutouts like I had made for this should be well over a hundred bucks for the four pieces. The rockers are also that thick steel.

I'm still looking for locknuts for the 10 mm bolts.

How do you tighten the bolts in the fork dropouts enough without pinching the rockers, so that the rockers can still move? Are they special shoulder bolts or something?

That's where the locknuts come into play. I tighten the nuts enough to allow movement of the rockers, but snug enough so there's no wobble. As I have it now, the two nuts together work like the cone nuts on a hub, they act as a locknut. I use a washer between the nut and rocker to take up the friction.

I'm going to try to order more hardware even though the last order was completely wrong.

I see, thanks, I thought I was going to have to get some special bolts, but that sounds workable to me :)

This will now be the upstairs bike, ready to ride at any time. Riff Ratt is now hanging on a hook down in the bunker. I took it for a test ride and it did great. I need a zip tie for the brake cable and a little more air in the rear tire. The springer felt solid and worked great.

Beautiful work:41: You raised the bar for me and others.

Lawyer lips of open slot forks (safety tabs) were not intended for your usage. I would suggest a secondary safety measure such as common safety washers if you're not using them already.... couldn't tell.
Another interesting safety clip.

"Lawyer lips"

I never knew what they were called. What is a common safety washer? I definitely want to make the front more secure. I was trying to figure how to use the threaded holes for fender braces to attach a big washer to hold the rockers on. I could also have my local welder weld on washers to the fork dropouts.

Common washer.

The type I use with road bike forks without holes. Supports the axle from the dropouts.

You're inventive enough to figure a solution.... A welder could possibly close the slots?

Again, wonderful distinctive bike! One of your builds for sure.

Here's a close look at the rockers. I put the lawyer lips on the inside, and figure the locknuts won't loosen enough for them to let the wheel drop out. But, I could get my welder guy to tack each one to the fork.

Appears safe enough. Ideally the double fork dropout openings should be closed for rockers. Your design allows the pivot bolts to wander in the slots with the safety washers following the same motions. Welding washers is place would make it more secure. Another option would be to open the rocker holes further to include sleeves for the rockers to rotate around. The sleeve bushings would have to be made slightly wider than the rocker width to allow the rockers to rotate freely. Then the pivot bolts could be tightened to max torque. No need for the double lock nut system. A more finicky procedure to achieve proper amounts of play though.

I'd rock it as is.

I hope to receive the right locknuts soon. 10mm was my order again, maybe they will get it right.

I was selling spatter painted bikes in the late '80s early '90s , and you have emulated this very well. The production guys at Diamond Back, GT, and Gary Fisher would have been proud.

The locknuts finally showed up. I noticed that using 2 nuts didn't really do the same as a locknut, they were a little loose from the couple of rides I took already. I have enough hardware now to do another fork like this one, just have to get the flanges and bracket made.
It's done except now I want to see how it looks with skin wall tires, which should show up any day. I got them for Second Helping, but might get another set if they look good on this bike.
