KO Spinners Bevel Angle

[danielmo]

Hi,

Does anyone know the angle of the bevel on the knock-off spinners? Is the angle on the wheels the same?

Thanks,
Dan

Do you mean the "mating surface" of the spinner hub nut to the wheel center hole?
The wheel is beveled or curved convex-like. The spinner hub has a flatter, less beveled/curved surface to mate with the wheel. Usually the paint wears away in one very narrow contact band on that mating surface. I don't know that you could give an angle or degree measurement of the beveled surface on the wheel, but perhaps possibly the spinner. I suppose I can get my protractor and estimate an angle in degrees. are you machining something of your own? what exactly are you looking to do?

[el-saturn]

i could measure the angle, as i DO have the proper instrument, if nobody here has it - presuming you need the angle which you'd use to make yourself a set of KO rims!? sandy

Sandy,

Thank you.

I am making the wheel centers that the spinners mate up against. The set of alloy wheels did not come with any and they can't mate against the raw aluminum.

Thanks,

On my Plus2, my Nader nuts are engraved "FOR STEEL WHEELS ONLY".

On my Plus2, my Nader nuts are engraved "FOR STEEL WHEELS ONLY". So, what makes the difference between the steel wheels and the Lotus aluminum wheels, so far as the knock ons? Why can you replace the steel wheels on a 26/36/45's with Minilites without problems? The knock ons on my S2 do not have any restrictions as to wheel material.

I have only seen them marked "FOR ALLOY WHEELS ONLY" that's Nader Nuts. For me Spinners with Ears are only for steel Wheels

I have spinners with ears on my car, and it is running the original alloy wheels...

Well, they can and do but I suspect it might depend on the alloy and the depth of the wheel at the centre.

My JAP wheels mate directly to the spinner at an angle of 45 degrees as I remember.

I agree with Roy on the angle as I have just checked a spinner and found it to have an included angle of 90 deg.

I have some Minilite wheels and the nut seats on the alloy of the wheel. Edit:- the nut seats on an alloy insert set into the wheel.
Cheers

the issue of the inserts and metal types has to be one of two things:
1) electrolysis? differing metals creating corrosion by contact, or;
2) metallurgy? differing "strengths" of the different metals not compatible? harder steel crushing weaker alloy?

ok, you scientists and engineers out there......chime in!

On the Lotus +2S Alloys they have these Inserts in the centre of the Wheel for the Nader Nut/ Hexagonal Nut

Alan,

Thank you for the picture.

The inserts look like they are made of a thin metal, almost stamped. I was designing some that are similar to the ones on the Panasports.

Thanks,
Dan

Yes, the Inserts are in Stainless Steel. Sometimes you can find them for sale if you're lucky. You need them to be a tight fit in each Wheel where they will stay.

Alan,

Do you have a measurement for the diameter of the inserts where they mate to the inside of the wheel center? I guess that would be the OD of the insert-able part of the insert(?) where it mates to the wheel.
