I purchased this magnetic pin finisher after looking at a number of brands, many of them much more expensive. I also looked at videos on YouTube to get an idea as to how these machines work and what to expect. This machine was rated on line as one of the best available in this price range. I also purchased some additional pins after reading the reviews.
When I received the machine (it was thrown on my porch like a heavy sack of potatoes), I immediately tested it to make sure it worked. It comes with no instructions...I advise you watch some YouTube videos. I started by cleaning the pins (they were quite dirty and required four to five three-minute sessions in the machine with burnishing liquid and one course of Dawn (without any jewelry, etc.). Note that you don't need to fill up the barrel with water...just a couple of inches. Don't add very much burnishing liquid or soap (just a few drops) or your will have a major mess to clean up. When pouring out the water, I used a very fine strainer with a container underneath to catch any stray pins. Most of them stick together in the barrel, but a few of them float on the top of the water.
Once my pins were clean I tested the machine on a copper bracelet with a lot of intricate embossing. I used the double-bar on-switch and set the machine for 30 minutes. This made the machine stop periodically and reverse direction. Perfect! The bracelet came out clean and somewhat shiny. This was not a mirror finish, but close.
This machine will work well for small items but not wire wrapped pieces...and it works a lot faster than a tumbler (although I will still be using my tumblers for my wire wrapped jewelry and larger items or those that require more polishing). I would recommend this machine to other jewelers.
Warning: This machines is not good for wire wrapped jewelry finishing because it will turn your piece into a porcupine and a mess. The little pins will jam themselves into the intricate wire wrapped areas...even a magnet cannot break some of them free.
