Spinners/knock-on's (off's). Who make new knock-ons?

[Brian Westmoreland]

Hey, new Gt owner, but I need to source 2 front knock-ons (off's, spinners). I get I need to size them, gather facts and figures, but as I'm stupid, left handed and right brained, two of the front units that came with my car no longer exist. I have a spare set, but want a front line pair. Appreciate the info. Happy new year to all.

It might help if you informed us of what GT40 chassis you have.

 

[Brian Westmoreland]

Yes, thanks. The car is a very early replica, circa 1980, spend time at RML, though RML or Ray Mallock Racing is still in question. The real claim to fame is it was fully rebuilt by Brian WIngfield in approx 2000 after a race accident. Reality is the original manufacturer is a bit cloudy. I've heard from many experts, but its origin is still a work in progress. That is why I indicated I know I need to gather facts and figures. Super appreciate the input and understand this input doesn't answer your query.

Check with Bob at Vintage Wheel in Ca.

 

[Brian Westmoreland]

Thank you Bill K. Looks like they have just what I need..

Vintage Wheel US, buy them unthreaded, get a local machine shop or a retired guy with a lathe to match your threads.

 

[Brian Westmoreland]

Thanks all, I reached out to Vintage Wheel, they had exactly what I needed on the shelf. The guy I spoke with even new the wheel(s) I have on the car. Looks like we are in business and the spinners are on the way. Just like the other brands of cars I have, I'm learning the resources out there. Appreciate all info. Happy New Year.

 

[Darius Rudis]

What are you using to torque the spinner on?

I bought spinners from Vintage wheel and had them machine to my hubs. I had to have my rear hubs re-machined as there were poor tolerances between the front and rears so I employ you to measure your thread height, width, and pitch front and rear to assure a good fitment we had to buy a special Whitworth cutter to re-cut my rear hub threads and to cut the new spinner threads

From my own experience, expect that you'll need machine shop help to ``fine-tune" spinner threads to the hubs even when nominal thread widths match.

The problem is once you cut the threads on the spinners and take them out of machine and lose the index going back to try to re-cut them as a monumental task.

I think the Vintage Wheel spinner threads are 60 deg (UNF) rather than the 55 of the original hubs which were machined from forgings. Sounds like you have one thread form on the front and another on the rear.
