-===== Manual Mill Clearance=====
-Members who are already proficient in the subject matter may apply to receive a clearance by demonstrating a
-core set of skills and knowledge that allow them to safely and effectively use the equipment.
-> Most tools in the shop require clearance before solo use. Each tool is different and most are expensive and/or delicate.
-During a Proficiency Based Clearance Instructors will provide Protohaven specific customs and rules for the
-equipment but will not provide technical instruction on the operation of the hardware, or software.
-If a member needs to gain additional knowledge or skill they should take a Basic Skills Class to learn the
-required skills.
-The items that will need to be demonstrated to gain the Proficiency Based Clearance are:
