Wow that is a pretty pedal. I really like that design. What do you use for transfer paper? I have had hit it miss (mostly miss) results using glossy photo paper, or glossy magazine paper but having problems having the toner to stick to metal. I am sanding metal, cleaning with acetone but still, only parts if the toner stick after ironing and soaking.
I havnt true pnp yet, maybe that's the magic bullet.
Anyway that design and execution looks amazing.

Thanks!
i'm using custom made vinyl stickers (like the ones used for car advertising...)

it is easy but you can't have small details.

i had some good results with chloride acid but not every time.

i had to etch some pedals this morning with my kid, so i choose the safe way, no chemicals...

Yep, looks gorgeous. Unfortunately I can't do any metal work so it's no option for me.

This is really cool. May try this myself. Though I'd have to use the toner paper/photo paper method as I don't have access to the car decals.

With your setup how long does the process take once everything is hooked up and in the tank?

I'm sure this depends on how strong of a powers supply your using but I'm curious if you can do more than one plate at a time with this method and if that would take significantly more time.

Ya man it looks super. So id love to know what I'm doing wrong. I am using glossy photo paper to print on, I sand aluminum, clean with acetone, iron it on full heat ( maybe I should take temperature to weed out variables) then put it in cool water and let it soak for a while and once paper is wet and falling apart, I gently rub it off with my fingers. Problem is that most of the toner has stuck to metal BUT NOT ALL OF IT!!! There will be whole sections that didn't stick so the whole process was a waste. I can't seem to get ALL the toner to stick. Any suggestions????? The few panles that actually worked enough, etched well with muriatic acid and hydrogen peroxide. I'd love to try salt or caustic soda, but I can't seem to nail the transfer part.

first you need a good layer of toner,
so tell your printer to have dense printing, verify that your black is 100% on your artwork too.

then iron at least 10mn the toner on the panel/pedal,
i use the back of a spoon to press the toner against the aluminium every 2 or 3 mn to be sure it will adhere well.

Cool! Well then, I will iron for WAY longer than I have been. I was doing for 2-5 mins. I love the spoon idea. I'm totally gona try that. Thanks.
