Got this from another forum really good

Tungsten dust can be toxic if inhaled long term, but few of us will ever see such exposure......... and highly unlikely from the currently available sinker products.

Problem with tungsten is the WOW cost......... it's way over the top.

Here's a few links I quickly gathered in this subjects regard (no recommendations - just sharing info....):

BTW - diamond bits can be purchased in quantity at reasonable prices online through the likes of EBay, etc.............

If you do try this project - buy more than a few spare bits - they can snap easily and do get dull ........

Cheers,

Welcome... almost every second day out on the water that sounds like paradise!

Might not get solved by water but guaranteed ground up and end up in the food chain.

There is no single argument that will convince me that it is ok to use toxic substances like lead. There is no other way for me then finding a better solution... will keep you guys updated as soon as I found something that works.

Worth a try! Just wondering how lonf the ping pong ball would last and how easy water might get in there? HAve you usedthe described set up?

THX guys
