As Adam levels up the precision of his machining, one of the tools he's using to measure the sizing of large parts is a granite surface plate. These massive reference plates are calibrated to be level to a high degree of precision, and as such need to be protected when not in use. So Adam spends the day making a custom surface plate protector and cover to slip perfectly over this piece of granite. A snug plywood blanket, if you will, for this important reference tool.
