[TheForge] Re: triangle bells/rebar

[Andy Vida]

I've been possessed...  first thing I'm going to do when I get back
home, after I sleep for nine days straight through, will be to grab
a length of 3/4" wrought iron tie bolt and forge a nice, big dinner
bell from it.  Then all I will need is the farm, wife, and chil'n to
make it a complete package.

I find it odd that after all this time I'd never even thought to make
a dinner bell.
