Okay, so you just eyeball it? Seems rather imprecise, but a starting point. Thanks for the response.

While I have not established a form that I use for fork alignment steps I have done so for the frame. Here's an example of that for a frame I built my wife last year. Note that some of the dimensions are in thousandth's of an inch. No eye balling here! Andy.

In the end, I've swapped both wheels and the handling is acceptable, but still a bit squirrely.
I am under the impression that my handlebar have excessive swetpback and are putting too much weight on the back, So I will try a different one and report back if handling improves further.

I thought I recalled you mentioning, at some point in this thread, that you had a recent issue with your back. It's possible that if you're riding with a tight back or your body in a different position to compensate, that might be having more effect than anything on the bike. The rider is the most significant force and weight in the whole system, so it's worth thinking about that possibility as you deal with the difficulties of pinpointing speed wobble.
Anyhow, the speed wobble is still present, albeit at a lesser degree...

I mentioned the frame at BB joint because that is exactly where this same problem originated on one of my bikes. The down tube had broken at the BB. Not all the way off, but half way around the weld.
Had a customer with a Specialized Secteur that had a speed wobble that would not go away. Replaced both wheels with known good wheels, replaced handlebar, fork, stem and headset to no avail. Replaced the bike and the problem was solved. Something in that frame was causing the problem, but we were unable to determine what it was.

While everyone was figuring mechanical problems, doom & gloom of mystery goblins.
Post 23 had it right all along.
That guy is a genius.
Anyhow, it's good to see you got it sorted & are on your way to a summer full of miles.
Cheers
