Pros : This is a GREAT tool!!! I LOVE doing round and oval lead and foil pieces... this allows me to finish the edges with Zinc came that I can either drill a hole into to attach chain/wire to hang OR I can solder "Handy Hanger" to to make displaying my pieces easy, not to mention the added strength that the zinc adds to the piece!
I have waited a long time to add this tool to my inventory and now wish I had done it a long time ago.
Cons : To start out, you need LOTS of "elbow room" for your came to move in. Also, a chop or came saw is VERY helpful.
