Transfer sheets?  Are you using the press and peel stuff?  I have never used it so can't help.

I print out on clear transparencies (made for an ink jet) and use a crappy HP F335 to print. These are the exact sheets I use:

Way cheaper than anywhere else.

For the resist film I use the Micro Mark stuff:

Just ordered 6 more packs today.

That tank set up looks pretty cool. It will take longer than 4 min. though. They are talking about copper on a PC board, not a solid sheet of brass.

Thanks Chris


I'm looking into printers will let you know when i find one

I'm unsure on which method i'll use yet some playing will be required for a cad programme i have Coreldraw 13

I've had great trouble finding ferric cholride here but have ammonium persulphate as a replacement so some playing needed for that to : ???

See with the press-and-peel stuff I believe you print right on to that. Then you fold it over the metal and iron it down. I heard it is hard to keep both sides aligned that way.

So even though I haven't tried it, I'd say the transparencies way is easier.

Ferric Chloride... I buy it in powder form and just mix it with water:

I'd have to look it up to be sure, but 1 pound should make a gallon.

You can get it in liquid form here:

Once my etchant starts to go weak I just pour in some muriatic acid (pool acid) to give it a boost.

Radio Shack has the acid, if you have those over there.

[Chris333]

Radio Shack... all the ones around here stopped stocking electronics. Seems all they care about now is cell phones.

I guess I got lucky when I went to the Fairhope Alabama one.  I did get their last bottle.

We don't have Radio Shack in NZ, an alternative but more expensive source is Radio Spares or Farnell.

Beware there's an account fee and prices are high.
