Modular Synth Panels

Thank you for the reply.  Do you use pnp?  I normally use the steel  
pads with the soap in them, like a SOS off-brand.  I have not tried  
acetone yet.  I tried an iron first because this is how I always do  
PCB traces with perfect traces.  That did not work.  The I tried a  
vacuum heat press 2 times without any luck.  That gets in 100% flat  
but still is not allowing a full transfer.  It is blotchy and only  
doing about 1 inch areas with no area having a large portion of  
correct transfer.

I see that you are using brass.  Have you tried aluminum?  And do you  
think that it needs to be a certain type of aluminum?  I am trying a  
8x16in size which is taking 2 sheets of pnp for each attempt.
