One thing to take note of. If you have a newer charger, it will not work without some assistance. The newer chargers have to have some current to get a polarity reading, or they won't charge. In other words, either "jump start" the charger (not recommended) or locate an old charger. I have a 2 amp charger that works great for this. The key is the size of the anode. If you're using a 5 gallon bucket, get a piece of thin stainless sheet and roll it to fit completely around the inside of the bucket. Then suspend your part in the center of the bucket. We've been using this at our museum for several years. It works great.
