[TheForge] Fatal acccident

[jerry Frost]

Right you are Todd. It came to me  just a minute ago I had the units wrong.
In reality it'd only be moving about 92mph. like taking a knife thrown by a
major league pitcher from 2' away. A little armoring would probably do the
trick, kevlar scale on ballistic nylon over padding aught to be enough
without inhibiting a person's movement too much.

I must be rattled more than I thought, I wouldn't usually make this basic a
mistake. Well, on top of Gordon's accident my brother died from ALS
yesterday. Nothing sudden about Dennis's passing, it's good his suffering is
over, still. Not that it has anything to do with blacksmithing I'm just more
dingy than usual.

I've started composing a safety talk for our next club meeting. I have a
little bicycle I can use to demonstrate the plane of rotation, spraying the
guys with a little water is so much better than something thrown off a wire
wheel. We have a rule about major bleeding at meetings. Violate the rule and
you have to leave the meeting immediately and go sit in a hospital till you
learn your lesson.

 Thanks for posting the correction Todd, it's good to have back up.

Jer

Jerry, your number is right, but you've got the units off.  That would be
surface feet a minute, not second.  That works out to 135.5 feet per second.
