Left to right; lead antimony anode with copper insert in the top for alligator clip contact; brass sleeve to hold the liner; PVC fixture to hold the sleeve & the liner to make electrical contact to the cathode. I use the basic chromic acid/sulfate bath. This bath is about 15% efficient, which means 85% of the electrical energy is wasted. The bath is slow but very reliable. The solution is easy to mix & will only require the addition of distilled water to maintain the bath.
