[SEL] Tod Engine Works Foundry

[Rick Rowlands]

On the 300 pounder at work if I put in a 200 pound solid chunk of steel and 
turn on the furnace I cannot touch it after about 10 seconds.  Gets that hot 
that quick.

PS I wonder how many people have had their rings melted off or at least burn 
into their fingers?   You would never think that would happen until it does.
