Hello, RPV.

The image below is an example of internal observation using an X-ray CT scanner.

It broke the other day and I scanned it at CT for reference and found internal gaps scattered throughout.

It is a tool called a universal extension with a shaft made of carbon and used for windsurfing.

The scanned product is the lower product in the image below.

The upper product was actually broken and the broken part was considered to be unobservable because of the rust.

The gap was 0.3mm in the longitudinal direction at about 4mm when measured with the dimensional measurement function.

I don't know if this gap is good or bad, but as a user I would appreciate it more if it were not there.

We hope this will be helpful to you.
