Well done, Chip.
Good work and a great gift. I'm sure your wife will wear it with pride.
When you get a chance you might enjoy studying " Art Monograms & Lettering" by
J. M. & V.C Bergling. Gem City Press, ISBN-0-910222-02-9.
You will enjoy seeing their shading of " Graceful Leaf Alphabet" on page 100.
The basics are simple, using something as a resist to keep the electrolyte away from areas you don't want to anodize...anything from waterproof tape to enamel will work. On this piece I first masked the silver knot with nail polish then dipped at 12 volts for bronze, masked the second knot then dipped at 26 volts for blue.
Very nice! Have seen past works from the old school anodizing by Patricia Walker, Judy Beaver, etc. I don't see these often with the current tactical styles. Some past shots I'd done long ago from Gary Blanchard:
Anodizing will wear at the edges or places of constant contact. It is a very thin layer although I am not aware of how thick the anodized layer is. Anodizing is pretty easy to remove with a 600-1000 grit abrasive for a redo when I've messed up.
I've flame colored timascus and surprisingly that has held up to pocket carry with minimal signs of wear.
This is super cool. Just joined the forum... been reading a ton of the threads... and your work really stands out to me. I'm a huge fan of knotwork and have done a few with rotary. Just now dipping my toe in the pool of air assisted scrollwork. Anyway, thanks for sharing. Really cool!
