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:
General Shop Rules
Be safe
Understands safety clearances are required as bare minimum.
Understands equipment must never be left unattended.
Understands why equipment must be reset after use.
Take care of the tools
Will not alter or use equipment beyond limits.
Will notify when maintenance is needed.
Keep the shop clean
Understands importance of cleaning up after oneself.
Will return borrowed tools to original location.
Understands anything left outside of your paid monthly or overnight storage may be removed and disposed.
Personal Protective Equipment

Notes
check your sleeves & loose fabric - bad!
Don't do rod or tubing. Sheet metal 16ga only
Blue bar is emergency stop, works in either direction
Lower idler roll in the back with the black handles - match sizes
Want metal going in and up, not digging in.
Back out both E stops (on machine and on pedestal)
Press power button, green light turns on
Make sure tension knobs on both sides are consistent - for top and bottom front roller
In/out step levers
Pull the lock on the right side of the top roll out to allow removing fully rounded pieces. Make sure to lock it afterwards!
Drill slip controler
Maintenance:
Every month - apply ways oil (from oil can resting on lathe) to metal bushings on idle roller. Spin the roller to make sure it moves freely

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
Turret Punch

Notes
Hole size gauge on the right side matches to pin names
Insert changing handle into square slots, push orange ball away to allow for movement. Make sure it locks into place, otherwise you'll damage the pin
Too close to an edge causes the sheet metal to buckle
Put in material, bring lever down
Upgrades
Hook for hanging the changing lever
Thick steel bolster plate with holes in it for preventing buckling on turret punch

Can use the hold downs to brace the sheet
Upgrades
Thumb/hand wheel for tightening the hold downs, plus a way to keep the bottom of the bolt from turning
Pull handle down, chunks the metal
Clean up underneath after
Upgrades
Find matching wing nuts for hold replacement down screws on notcher
Maintenance
Verify the shafts for the cam section are in place and not slipping out; add some ways oil
