Hi Andy, I've been a lurker here a long time! Just now having some questions and getting around to actually doing something with my circuit.
Yeah the board I was asking about is for the "switching and Capacitor Bank" for my Pulsed EDM. The control circuits will be on a strip board for now, in case I have to make any changes. (but of course it will be perfect the first time ;-) )

Hi, Cary,
Welcome to Homebrew_PCBs! Are you planning to make a board for an EDM controller? I keep wanting to update my design and put it on a pcb, but just haven't had time yet.
Speaking of time -- honestly, I think toner transfer would still be easier and quicker than messing with tape, etc. If you were wanting to block a large area, then the tape/contact paper/etc. would be great. But if you are wanting to make traces -- even straight, fat traces -- I think trying to get the tape cut and laid out would be a pain. Meanwhile, toner transfer is really very easy.
The only thing that would be easier than toner transfer would be the Sharpie pen, or similar resist pen -- just draw your traces with a ruler, or freehand if you don't need them to be straight.
Whichever way you decide to go, good luck. Ask back as you have questions!
Andy
