Hand Brake Clearance (DRAFT)
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:

Notes
- Make sure electrical stuff is clear - sometimes it gets hung over the brake
- Handles on sides are for raising/lowering the fingers - the right one tends to slip, be careful
- Red counterweight on left side helps balance the front lever action
- Clamp fingers down onto piece using the levers, then lift the front handles to bend.
- Careful when taking fingers off - they can chip and break
- Why switch fingers? If you are making bends in different axes, would have space to keep the bent parts clear of fingers
- Switching fingers
- Place triangular piece of wood under the fingers to prevent them from falling
- Place hand under finger to prevent the finger getting damaged
- loosen with 6mm allen key
- When inserting, push up to the top
- Upgrades
- Safety wired allen key onto the machine for changing the fingers
- Triangular piece of wood to hold the fingers when changing them
- Machine a shaft collar / stop thingy for the stop rod on the brake
- (cosmetic) Sand blast and powder coat the counterweight rod
- Replace handlebars (cracked / bent close to the machine)
- Wooden caddy for brake fingers when not installed in the machine - an inverted crib so they stay secure and slide to a safe place
- Maintenance
- Ensure pins are in place on handle, plus some ways oil to lube the mechanism
- Ask Cord - label the 2x4s at the finger brake with what they're for
