Stamping Tests
 

We've secured several blocks/heads (unsalvageable) of the 65-72 era for testing stamps/re-stamps using Thermal IR. We're tentatively scheduled to conduct the tests on the 22nd. I will post the results, what could / could not be determined, etc. Our scientist believes we will easily be able to detect those pads/stamps that have been altered, and possibly even be able to reveal the characters that were initially ground off.

Interesting-- Then another term that is currently under used could enter the mainstream of the hobby- a "restamp" will become a "restoration block" if a shure fire way to easily detect the restamp is finally perfected.

or use the term it has restored numbers lol

Thanks for taking this on. I hope it is successful!

Yes...let us know. My original block was decked by a racer to get the "True" 11:1 compression and is still that way today. I would be interested in what you come up with.

Prosecuting attorneys have been doing the "acid thing" for several decades now to make the ghost images of VIN #'s reappear after having been ground off.

I've been researching the acid test. It seems to have about a 50-70% success rate from what I can gather. Not too shabby. I'm just testing this method and perhaps it can do better? We have the thermal IR camera for free for testing purposes and the scientist is pretty confident so why not give it a go!

Will this method work on all metals?

That's what I'm told......what did you have in mind?

Yes .....And not just metal.
We have used this technology in the aerospace field for quite some time.We primarily use it to detect delaminations in composite structures.Once a composite layout is delam'd it acquires moisture.This is easily detected with the TIC.
