Three pieces of rare red beachglass set in Argentium Sterling Silver

  Aloha, I'm Gary Anthony The JewelerAtLarge TM... new to all of this, still glad to join. I've been a jeweler for 30 years now, and live on the Island of Kauai creating jewelry using genuine beachglass and Argentium Sterling Silver. I also create some large fish sculptures in copper... all the local fish - Ahi, Mahi Mahi, Ono, Ulua and on...
I'm wondering if anyone can give me any feedback on using a scroll saw to cut out my fish...(24gauge copper) I currently use heavy shears, but then I have to spend extra time finishing the edges. Any thoughts?... I like that delta one, but hear it might suck.
