vd Use your tongs to pull the bomb out of the coals, and another
vd set of tongs to unscrew one end. Do this right on the edge of
vd the forge and right ABOVE a bucket full of old motor oil. Now
vd tip the contents of the bomb into the bucket.

vd The bucket is going to catch fire. Don't worry about it....

vd Collect all of the blades in a shallow pan and cover them with
vd an eighth of an inch of motor oil. Now set the oil on fire.
vd Allow the fire to burn out. It's going to be smokey as hell
vd so you want to do this outside of your shop. When the fire
vd goes out, tip the blades out of the shallow pan onto a piece
vd of iron and allow them to cool.

I'll give this a go in my 2-car suburban attached garage...a good test
of the local fire dept, get the lads out of the station house playing
jokes on each other.

Really tho, great fun reading about the old-timey ways. Guess I'll
continue to pay the $10 at my local Ace HW & Aviation Supply...
