Ronn, the most simple is to use 2x4 lumber and deck screws to frame the size you need. Then use heavy plastic (that comes on a roll) or a torn used pool liner to line the inside of the framework. Once the 'pickeling' process is complete, drain the liquid and disassemble the framework. Store until the next time you need to do the process and modify the framework to fit your needs for the next group of parts.
