I actually just did some pnp transfers last night. I just needed to go to 100, 200 grit to get a decent transfer. THe toner on my printer is low so my transfers
kinda sucked. Spent hours today with nail polish.

I used model paint and it works great. The PNP shit seems like it doesn't work very well at all. I had to use an iron on it for like 40 minutes to get any transfer. I read somewhere you can use photo paper as well. Is there any truth to that?

People have had good results with ink jet photo paper running through a laser printer. I did it once with magazine paper and it came out great. It seems like every time I etch the results are different. I did well tonight with a couple of boxes. I was going to do a small batch of 2 fuzzes but it took me all night to do two and they aren't even done.

So after several false starts of ironing on the design, it not sticking properly than having to spend a chunk of my life sanding it clean again, I have a rough transfer now that I'm going to etch even though its crooked and dodgy. I figure the chance of the etch working is low enough that its not worth getting too anal about this one.

So i can just use a sharpy to fix the bits that didnt transfer properly?

Sharpie might work. Nail polish or a paint pen would prob be better.

You didn't invert your graphics. Doesn't the etchant eat everything that isn't painted?

Yes! behold what I hope it will look loke approximately....



Nail polish it is. I fear the fine detail will be eaten, but hey, this is an experiment.

LOL! I realized I was wrong this afternoon. I etched my Robot Devil and it look pretty cool.

I've been having fun etching.

What an afternoon!
I ended up sourcing hydrochloric acid and peroxide from an industial chemical supplier.
I mixed up a vat of 2:1 and dipped my first pedal.
Z0mg!!!!! Within 5 seconds it was bubbling furiously as toxic fumes bellowed upward from the vat! I dunked it in water to cool it, and dunked it in the acid again.
It was crazy meth lab shit.

It burned thru the pnp mask within 5 seconds, and the nail polish i touched it up with in another 5. hmmm



The reaction was way too fast.

So the next one I diluted the acid mix with a few litres of warter. This time it took ages to get the acid to work. Finally I got a reasonable etch, but it looks like it ate thru a casting layer, and its blistered in lots of spots.



The black bit is kinda smudging, but I dont want to sand through it. I think I'll spray it with clear.

Thanks for watching!

This shit works great http://www.radioshack.com/product/index ... Id=2102868

No mixing or anything.

Thanks for all the help guys.
I'm 75% happy with the etch, and it sounds great.
Thanks for looking in on my first pedal building foray!
