[TheForge] Cone Question

[Andy Vida]

OK, how's about this:  rough out the form such that you are able to
do the joinery at the edge, whether it be solder or a weld.  If weld,
do on outside only.  Grind flush.  Have ready and male and female
die.  Do you have a Dake press?  The very rough cone goes in, ram it
home, and hopefully a more or less perfect cone pops out of the die.

The critical thing here is geting a good seam.  Once you have that,
getting the rest of it straight and true should be a piece of cake
with a dieset.

	I have pondered the profound paradox of the ArcLight Raid.
	In the midst of the horror and the death and the destruction 
	of the Bombs there is the glittering beauty of their split 
	second action that is a reflection Of something far deeper 
	and eternally abiding which fills my heart with a sense of 
	peace and knowing as I sit, transfixed, staring into the 
	eyes of God.
