I've seen Tom's hub -- it is very nice. You might want to confirm with Blas that your particular SPF supports that steering shaft (I don't know). Here is a thread though that has nice pics of his work:
Bolt-on Steering quick release hub Now if you're curious, the QR hub of mine in that same thread, made by ERA, is mostly the quick release hardware manufactured by Sweet Manufacturing. They manufacture not only the quick release portion but also the splined stub that goes into the quick release. ERA welds the splined stub to the steering shaft and then dresses up the quick release portion to make it virtually invisible. Fabbing it like that would be an option if you were so inclined.
