I like to make clocks for wedding presents when friends or family gets married. Its is my gift that signifiys the meaning of love and time…..anyway I have been trying to find some information about etching copper so that I can make a design and use it for my clock face.

Does anyone out there in LumberJock land have any ideas that would help me get started?

Thanlks for your time

What type of etching are you looking for. I can teach you how to acid etch so that you would have a rough dull surface with bright shiney letters or numbers or vice-versus.

I make arts and craft type clocks. I would like to design a clock face in my CAD system, print it out on laser paper. I guess there is some kind of special paper tp print it on. Transfer that to a piece of copper using some sort of dip system and/or electrical current and I can leasve it that way or hammer it from the back side.

Thanks for any help you can pass along

For copper, you can print on laser paper. You want the paper to have a fairly tight grain. Print it in mirror reverse.
Now IRON it onto your copper plate. The heat should fuse the laser toner to the copper. DO NOT peel the paper. Soak it in water until the paper softens and you can pull the paper without pulling the toner off the copper. Obviously this takes some practice. From there you should have a copper plate with the resist in place and you can soak it in a shallow tray of muriatic acid to remove the exposed (not printed) copper areas.

This is from memory and I haven’t done this in about …. 20 years? Anyways… for freehand artwork you can actually use a sharpie as the resist. You may have to pull it part way through the etch and reapply the ink, but if you use a CD marker, they use a different ink and it’s a little better resist.

I’m sure there are more elegant ways to do this, but this is how I made copper etchings years ago.

I don’t know if any of this will help, but you might want to take a look at them. To be honest, I have not taken the time to look at the videos, but they might help.

Good luck. I know your clocks are beautiful and this will really make them exceptional…...by the way, do they give the clocks back to you when they “split the sheet”. That seems to be the way it is nowadays.

Can’ seem to attach the link here. I’ll send you an email and see if I can attach it there.
