I haven't tried exposing a photoboard, but see no reason why it would not work as you suggest.

Evenness of illumination would perhaps be a practical problem. with the smaller tubes most often used by amateurs.

Having etched an X-ray image onto the board, one might then print from it like a lithograph! smile

Cool, thanks Chris.

I'm still looking for lead, it seems to be less common these days due to everything becoming "green".

Unfortunately yes, try car batteries, it is easy enough to melt. Also, make sure to neutralize the acid. Sodium bicarbonate should work if it is done carefully, but someone on here may have experience with that.

I believe fishing weights and weights for hobbyist gravity-racer (pinewood derby) cars are still made out of lead. I don't know if you can get these in quantity, but it is worth a shot, I suppose. You could also talk to people in the medical profession to see if they throw out lead aprons or are replacing x-ray equipment/shielding (one can hope).

Another source for lead could be from diver's weight belts. That is of course if you can find them.

How much lead do you need? Sometimes, if you go to tire shops that install tires, they have some. Ask if they have any lead weights (I think they are used in centring) you could have. Several people got buckets of lead.

ADVARSEL!

Use 1mm - 3mm roofing lead which you can cut with tinman's snips.

Do not start heating big tubs of molten lead metal!

You have only one brain cell* and the one environment!



*Perhaps more at the moment, but not more after heating molten lead for a while!
