Very clever.  I must have missed it before.  I might even experiment
with just pushing the rod until some light blue shows up around the
hot spot -- all depending on just what the workpiece is.  Have to
remember that.

I think my most bizarre hole-making was on my very first forge. Utter
novice that I was, I had struggled to form a sheet metal cone-shaped
hood and bolt it to the little forge only to discover that I needed
1/4" aligned holes through two layers of sheet metal to fasten the top
of the cone together.  Too springy to drill. Dreaded starting over by
taking the the horrible, floppy, springy thing apart. So I clamped the
metal and a Balkan Sobranie can [1] full of sand together and shot a
hole in it with a .22 short. Worked great.


Tnx Frosty,

[1] Balkan Sobranie is no longer available so you can't make holes
    this way any more. 8-)
