Ask the Cuemaker...cue xrays....

I don't know if he is still on here but I remember Edwin Rayes is an x ray tech who used to do his cues. Shoot him a pm. Chris.
You might try contacting Kerry Zeiler (Zylr Cue) on the board here. Believe he was/is a radiologic x-ray technician and has some past experience shooting cues.
One of the first things that you have to make sure of when doing cue x-rays is aligning the wood's grainlines perpendicular to the plane of the x-ray film as MOST cracks run with the grain and not across it. Some fractures do cut across at an angle (area of interest is the bottom of the joint pin around 2-2.5" from the joint face). But normally the effect of such fracture is immediate.
Stress fractures, appearing as black lines, occur when abnormally excessive external side forces are applied to the structure.
Blow out fractures are from extensive internal forces. Such as in jointings where the wood surrounding a cavity is subjected to hydraulic or combination of Hydraulic/pneumatic/mechanical pressure. Areas of interest for such occurance is the A-joint and the joint pin cavities.
Inadequate knowledge in manufacturing also appears and so does "special fixes" (ooops) done during the cue's manufacture.
Under the former you'll usually find oversized cavities or undersized tenons and insufficient adhesive coating in cavities. In the later you can find replugged threaded cavities as an example. Shimming of the A-joint faces also fall under the ooops department.
You can also see natural anomalies in the woods where the softer areas appear darker than the surrounding structure. Or unatural where, believe me this surprised me too, a staple was left inside one of the inlayed point's cavity. I don't know what the staple was for. LOL
I hope that this somewhat helps you out.

Depends on the FS speed. Remember too that the cue has less than 10% the liquid content of the human body. So for a 400 FS combo at 40FFD and processing factors available, I use finger technique 2mAs@48kVp.puckdaddy said:
I also try to shoot 1 cue at a time and collimate/mask off around it to minimize distortion and scatter(albeit very minimal).
nice x-ray thnx
Taking them at dead-on overhead might be better.
Shows cavities ( dark ) and metal ( silver ) show better I think.

Interesting. It looks like you used an inspection fluoroscope for these as the denser parts came out black.
The coarse thread stud bolt used looks like a 5/16" diameter (estimating that A-joints are mostly in the range of 26.4mm-27.2mm)
Here's a side by side for viewers to easily understand what they're looking at. There is a possibilty of existance of an air-filled void
due to the observed difference in density from a comparable area.
