Went back up and played till it was time for lunch with the kids
I am playing with 36g dead soft copper - comes on a roll and is easy to work with - scissors !
It does become work hardened and is light
Making a T fold
I dont always anneal since its so soft to begin with
I cut a piece that would be fit in my 3" ring for pressing - extra on the sides as I will be folding in a bit of material to make it smaller
I annealed the piece - U use a bernzomatic (from home depot) with the quick ignite switch (makes grabbing and firing fast - then cooled ( didnt do any scale removal etc..)
then matched the ends - I did not squish it in half - leave it round
then I placed in the vice and left about 1/4" above the lip
tighted vice
take your chasing hamer and tap lightly the end which will cause it to start to collapse
I tap all the way to the ends first
then wach some more
till its flat
nice an smooth
it does not take long
I open the vice and take out
You can see it looks like a T-rail
slide open the two largest pieces that are folded together
open like a book - I dont pull too much
I place my restraining ring over top to draw the circle to cut
just used a marker - I positioned what portion I wanted to be within the design
because its so thin I used a plain pair of scissors
my circle ready to be pressed
I put the heart die (from Potters USA) on a base
then I put my 3" restraining ring ( I had it cut from a piece of steel pipe - was not sure the height so I wanted to test - I am going to have it adjusted to be the full 1.25" and put a solid base welded to the bottom - but this works
then I place the piece with the fold face down - the T-is on top
Placed the polyureplug that will push the metal down into the die
this is a 95 durometer
then I placed a pusher cap over the plug
Placed it in the 12 ton press
bring the pusher down to touch the top
gave it 5 pumps
what it looks like after in the die
from other side of the die
5 pumps too much it is tearing away - although not a bad thing since \i am going to cut it out anyway
I switched dies
I did a flame patina - which turned out beautifully - more purple that ended up in the center of the fold
So positioning can really be helpful when deciding on placement of where you want your fold
