Receiver X-Ray?
- Thread starter jsitz
- Start date
I read a post about this sometime ago about ReWalt M16 receivers and since then I’ve tried to find a business that would x-ray guns, parts, and suppressors.
I’m still looking as well. Hopefully one day someone may have a lead we could follow up on?

What exactly are you trying to see?
Most likely, a diagnostic xray unit will not give enough resolution to see cracks or hairline fractures in the metal. You need industrial imaging systems that use a gamma source to view high res detail.

We used the portable X-Ray machines where I used to work to X-Ray all sorts of things. We had two different kind (dental & medical), but we always used the medical, because the collimator blades could adjust out further. The ma and KV adjustments were sufficient to allow us to shott X-Rays through a variety of materials, including aluminum.
When people X-Ray a lower, they are looking at whether the lower was a reweld and if it was, the quality of the weld itself.

Ok, that would make sense.
You could look around for someone who does Lithotripsy procedures. Those are the guys who break up kidney stones. Often, they are small private companies who keep the equipment in their garage. You might find one with a c-arm willing to let you image some stuff.

try a veterinarian
If your on good terms with your vet, he probably has an Xray that would work. We used our local vet's Xray to examine parts that have failed at work. This is a cheap solution for situations when you don't need the knowledge from a metallurgical analysis lab.

It might help if you told us what part of the country you were looking in.jsitz said:
You would likely need to look around for an NDE contractor. They will have the equipment as well as the knowledge for how to shoot metals. We've got a pretty good sized NDE department where I work, but there's that "no firearms" policy. Of course, they are set up to work remotely as well.
Actually, gamma rays are used in industrial settings because the actual x-ray equipment can be bulky and difficult to move around. X-ray images usually produce a better picture, but you can do pretty well with an iridium source. Cobalt gives a really grainy picture, but is more dense, so it can shoot through thicker material. A radioactive pellet is easier to transport, and doesn't require any kind of power source. You just need a lead shielded containment. When you're ready to take your shot, you just crank out the source for the required time and let it expose the film.medphys said:

I can only comment on some re-welds performed in the late 70's. The receivers were cut in the same area, but not the same spot. The manufacturer would take a long rear section from one gun and a long front section from another. He would then machine them to the proper length and hopefully use a fixture to hold them in place while they were being welded together. Welding was not as developed as it is today so there were some problems with shrinkage, warpage... Some turned out fine.
Kind of cool to see this post. I work at a place that does industrial casting but x-raying non work stuff is a big no no......That being said,
it wouldent be too hard to do but as with most places bringing guns into work never goes over well.
something like a receiver would be pretty easy, generally it's about a inch or less thick, and some sort of steel alloy (we generally do inchonel, stainless steel, rene and hastolly) so your looking at something around a 220-270kv shot for about 1.2-2.0 min depending on film speed and tube height (tube to film distance). I've never worked with medical, dentists equipment but I dont know if it would be strong enough kv wise (penetrating power) because most of it's designed to go through bone/tissue and do it very quickly.
Your best bet would be as mentioned to go to someone/place that does this and see if they use digital stuff. Usually film is more expensive and may take a few tries if they are dealing with a unknown. That being said thing like shoes, candy bars and hobby cars are much more challenging to x-ray I've been told. http://i531.photobucket.com/albums/dd353/SWMR2/IMG_1847.jpg?t=1292795090

If you're near Houston there are a whole bunch of NDE (non-destructive evaluation) companies that use x-ray and ultrasonic testing to NDE oil field equipment.
They'll NDE whatever you want, our x-rayed items return with pictures.
