Yes, it's a heat press. A friend of mine who is a machinist made it for my xmas present. It's all steel plate and has a hot plate element in it with the temp control too. I think it gets up to 450 degrees which is more than enough to etch an enclosure. I haven't tried it yet because I had to add a piece of high heat silicone to the top plate to make up for inconsistencies on the boxes. I hope it works....

HURRY UP...

And use it.
We all want to see how awesome it works.

I got some glossy presentation paper today.
Office Depot didn't have any photo paper that was thin enough for my printer.
Max for my printer is around 32lbs or so.
All they had was 50+lbs :(
Hopefully tonight I will get a chance to try the presentation paper.
It was about $15 for 250 sheets, about half the price of most of the photo paper they had.
Both sides are glossy, although one side appeared to be a little shinier than the other. But that may have been a trick of the light in the store.
 

On another note, anyone know where to get blank magazine paper?
I often do double sided boards and while my light table is good enough to allow me to line things up, it barely does so.
With magazine paper being thinner, it may make that part of it easier to do.
Magazine paper with print on it, makes it a bit tough to line things up properly.

I'm sure at some point, I will probably need to put brighter bulbs in my light table though.

Rob (h).  BIG thanks for your help mate!  Between your sticker paper tip and sandpapering off the toner, my etches are looking a hell of a lot better.  Sandpaper did the trick, no more blackening! 



Now I just have to work out how to get rid of the patchiness :D

Its really just a presentation thing..the board works ok.

Totally agree with the sharpie!  Utterly useless!  I just used a "artline" permanent marker in a couple of spots on this board and it worked quite well,  I'll have to buy one with a finer tip though.

Fingernail polish can cover some of those spots that the toner missed.
Can be a bit tricky if its near a trace or pad though.

Thats on my list.
Speaking of...
I'm guessing there is a DIY method of putting the photo resist stuff on copper clad?
Links or info perhaps?

And here is the result of using the presentation paper.
Its glossy paper so it turned out fine and dandy.
Not perfect, but useable (As long as the circuit works that is :) )
