OK, so a chain saw might be a little too much for this project. The jeweler's saw is slow going, but about as fast as I would want to have it go in order to produce consistent, accurate cuts. Below are a few shots of the progress.
|Sawing away. I use a brass bench pin I made just for delicate piercing operations like this one.|
|Now the reasoning behind the silver sandwich is apparent. Lots of sawing ahead.|
|I remove excess material from the edges. Since it's easier to work with a large chunk of material, I carefully cut out the links in stages so I'm always holding the larger chunk and removing link plates one (pair) at a time.|
|One by one, links are cut out (top, left). What you don't see is the pile of dust and scrap below.|
|I inserted the pins to keep the pairs of plates together. I keep the links in pairs throughout the process to ensure perfect alignment of the chain.|
