Wheel detailing

[Adrian Harris]

Several builders of the 222 have modified the wheels to remove the raised central hub and replicate the curved detailing around the face of the wheel.

I've looked online at various radius turning attachments for the lathe but I've not found one which would appear to be suitable so I'd be grateful to know if there is another way to perform this detailing.

I don't think my co-ordination is good enough to do the curved profile free-hand

Hi Adrian,

I have made a "profile chizel" to create the desired shape of the wheel. I started from a 6 x 6 mm. tool bit (a special high carbide piece of steel) which I carefully shaped with a rotating grindstone.
This is what it looks like from the top view:


And from the bottom view:

This chizel is positioned square to the face of the wheel.

I hope it makes some sence.

As with all things, there's more than one way to denude a feline:

This is Dave Battson's method, gratefully received by email:

I profiled my wheels using the steps below;

1. Fix the wheel onto the chuck
2. Set the tool to touch the wheel at the at the middle (highest point) of the required bump
3. Fix a dial gauge to the top-slide, with it's axis parallel to the lathe bed
4. Create an exact 'negative' template of the required bump profile
5. Fix the template to lathe bed, so that it touches the dial gauge at a point corresponding to 2 above ie. middle of the dip
6. Set dial gauge to zero
7. Start up lathe and move cross-slide back and fourth whilst using the top-slide to keep dial gauge reading zero



Obviously, well worth practising the cross-slide/ top-slide coordination first, before committing to a wheel, but it's not too difficult to master with time.
