Thank you- yes I think the convention is to make the holder the nominal size, and the film a little smaller-
X-Ray films vary. I know from experience that 8X10 Kodak CSG does fit standard holders and is 1/16 smaller in both dimensions than nominal. 7x17 is exactly 7X17 and thus needs to be cut for my purposes to 7x11 and 5X7 to the 1/16th smaller dimension. I cannot answer whether 7X17 Kodak CSG fits any 7X17 holder.
My 11X14 Kodak CSG measures 1/16th smaller, but I don't have standard holders to try it. I use a DIY holder.
I assume all X-Ray films are similarly sized in comparative formats for competitive usage, making them interchangeable, but I do not have empirical proof.
I have 8x10, 11x14 and 14x17 film from Kodak, Fuji, 3M, Minolta and all the x-ray film fits my holders. I think there are ANSI standards for the films I mention but I'm not sure.
Ok, thank you- I'm making my own holders, I think I have enough information here. I don't have the film yet, which is the problem...
A few still life photos from the weekend. Kodak CSG @ iso 50. Caffenol-CH x 15min. I think I will go back to Caffenol-CM stand to reduce grain.

Another possible reason why xray film is not as sharp as conventional film could be due to its lack antihalation layer. Thoughts?
Early in the morning. Son's tree house that he built when he was a boy. Not much left of it.
I wanted to figure out how much each 8x10 x-ray photo cost with chemistry added for processing. Here is my assessment… others may vary depending on actual film used and type of chemistry…
Fuji HR-T: 100 sheets $35
PMK: one hundred liters (One liter per sheet of 8x10) $60
TF-4: ten liters (One liter per ten sheets of 8x10) $107
TOTAL $202 for 100 sheets of film.
Notes:
All prices include shipping from supplier to my home.
I’m going on the assumption that one sheet of 8x10 Fuji is equivalent to two rolls of film (160 square inches for both sides). Using the TF-4 published capacity of 20 rolls per liter, it works out to ten sheets per liter.
I’m also tray processing the developer which needs at least a liter to slosh the film
So, it roughly costs $2 per shot.
I think I can reduce that a bit if I can figure out how to make my own fixer.
