I have a new car that only has a bottle of squirty gunk in the event of a puncture.
My old car (going to scrap) has a steel space saver wheel (unused) that will fit in the boot of the new (to me) one, all the wheel dimensions are the same except going from 12m to 14m.
Can I get a machine shop to just drill them straight through or does there need to be anything special (like an alloy wheel would need to sit the nuts correctly).
Does anyone know?
Just buy a spare wheel. I don't know any machine shop that would drill holes in a wheel. They're not just a drilled round hole for a start. Also have the spigot hole to think about.
For the price of a SH wheel, even I wouldn't bother, as above.
I don't know any machine shop that would drill holes in a wheel.
If I knew a machine shop that would drill holes in a car wheel for a member of the public, I'd avoid going to that machine shop.
Bigger bolt hole = bigger nut = bigger countersunk section of wheel = big NO NO.
Plus your altering the design and CE spec so if it goes tits up your in the poo poo.
