Flattening and cleaning copper sheet for etching

tonights project is to flatten the 3 x 4 sheets for etching

Even when you use the shear or scissors you get a bit of a curl and bends in the copper
you want it as flat as you can to put your design on so its even

I use my two steel  blocks and a hammer - to tap on this way  you dont get hammer marks on the soft copper and because its soft it flattens the piece out

I position it in quarters
and tap tap tap 
takes away the curl of the edge and levels it all out 
all nice and flat and ready for cleaning

I got some nice hot water and soap and then put them in to cut the oils 
as I pulled them out and gave them a squirt of windex and cleaned them up  being careful to hold them by the sides so any oils from my hands did not get on the clean surfaces -  oils can make the resist not adhere to the metal surface
cleaned and ready for the resists 
I will wrap up to keep any dirt or oils from getting on them till I am ready to apply (hopefully tomorrow)

  6. I have always been interested in copper artwork, but never knew that much about it. There is a store right by me that sells copper sheets, and now I know what to do with them! I will have to go pick sheets up tomorrow and give it a try. Very useful information, and I look forward to reading more posts.
