Magnesium compomotive centres - where can I get them xrayed?

[jamieandthemagic]

Mates got some splt rim compomotive th wheels, with magnesium centres.

Any suggestions on where we can get them xrayed prior to any refurb (preferably in the east of England).

Compomotive have already confirmed there's no chance of reproduction.

What defects are you trying to find? How big are they?

Cheers for that, check for cracks and issues prior to any track use.

My advice ? Find some other wheels for track use .
keep the old ones once refurbished for display.
We have had wheels that were inspected and declared good fail within a couple of track sessions .The repeated heat cycles of track use makes mag wheels brittle and the high loads of track cornering caused failures between the stud holes .
We had new centre sections made from solid billet and used the rim sections again.
10j x 13 fronts and 12j x 13 rears on a V8 MK1 Escort .

I am no expert in this, but know a fair amount about NDT.

A Dye penetrant test will be better/ cheaper at finding cracks than X ray. Not sure what companies offer this to the public though?

That's sounds logical, and good advice, but "how" were they inspected and declared good?
