Headstock bolt
John
In response to this and your email the drawing of the ball race headstock shows that it is a stud with a nut on each end. Just to confuse the issue the drawing does refer to it as a "head bolt". My taper roller system is the same but the drawing correctly calls it a "head stud". Will send you copies of the two drawings.

The hole in the centre is for a long bolt which secures the top and bottom yokes through the steering head. Nut and lock nut under lower yoke.Colin Sparrow

Sorry I remembered it wrong. It's a stud, so there is a nut in the middle of the top yoke. Also, the stud screws into a thread in the bottom yoke and is secured by a single lock nut underneath.
If anyone can tell you the thread size in the bottom yoke, you could easily make one if you can find some suitable steel rod.
I would think the thread in question is Whitworth (BSW), but I can't quote the size. Someone will know.Colin Sparrow
