I hope this is the right SE for this question. If not please point me in a better direction. I'm working on a project that requires a counterweight in a tight/organic space. I'm trying to maximize the weight so I need a dense material -- the denser the better. A material that's easy to machine would be OK, but ideally something that could conform to the space would be better.
These requirements led me to consider lead shot or lead wool as an option. My concern is obviously safety. I'm wondering if it is safe to encapsulate the lead with something like epoxy.
My understanding is that lead poisoning typically arrises from ingestion, inhalation, and dermal contact. I imagine that if I encapsulate the lead in something like epoxy then those three pathways are no longer relevant, but I'm just not sure and would rather avoid taking chances. Maybe the only risk is during the encapsulation process? Clearly lead is used in a variety of applications with human contact (e.g. lead vests for x-ray) so there must be someway to properly shield it from the surrounding environment.
