Re: Coins as car weights

Another option are lead ingots from Bass Pro Shops. Come to about $1.80 per
pound. Easily cut to 1/4, 1/2, 1 oz. sizes and attached with epoxy. Just
be careful when handling. As BPS's site says, "Do not place product in your
mouth."

Best,

Go to your local garage and ask them to keep the weights they remove

this outside.
Sound advice, because there are things like antimony in the lead
that aren't good for you. But should you worry about the lead? In
reality, the vapor pressure of liquid lead is extremely low. There will
not be enough lead vapor that it could even be measured, unless you
have a spectrograph. (Of course, I don't recommend leaning over the
bath and breathing deeply from right above the melt.)
