[TheForge] Cone Question

[Peter Fels And Phoebe Palmer]

I've done a bunch of these by hand  in years gone by. Fake up a tapered 
swage to work into. Then start  at the seam edges and work towards the 
center using 2  cross pein forming hammers... The blunt one for the base 
and the sharper one for the tip. Get the areas next to the seam edges 
right before doing the center and tap them closed  and finish over a 
mandril. Gets pretty quick with practice.... Using at least 18 ga makes 
it easier.....Pete  F
