== Why subject matter experts? ==


Cultivating an up-to-date wiki on A2 shops, machines, and tools will help to make our space more welcoming and useable to the entire community, whether they are long-term members, new staff, occasional users, or potential new members.

Subject matter experts (SMEs) are crucial to building clear and comprehensive pages on A2 shops, machines, and tools. There is a wealth of knowledge which lives in the minds of SMEs. If you're reading this, you are likely someone who has a vested interested in documenting that knowledge so that it can be documented for both preservation and dissemination purposes.

There are lots of different "types" of people who can serve as subject matter experts. In building the wiki page for a particular shop or tool, it is likely that you will need to draw on the knowledge and efforts of multiple people. Regardless of where/how you find them, a subject matter expert should exhibit one or more of the following traits:

* Knowledgeable about an A2 shop and what equipment lives there
* Knowledgeable about a specific A2-owned machine or tool
* Knowledgeable about a process (e.g. welding or sewing) which is done in an A2 shop
* Experience with machines/tools which are similar to the ones owned by A2
* Has time and motivation to contribute to the wiki


== Where to find subject matter experts? ==
{{EyeWarning}}


Potential SMEs can generally fall into two categories: people with A2 specific knowledge, and people with process/machine/tool expertise.


Some examples of people with A2-specific knowledge include:
=Description=


* A2 shop leads (current or former)
A sand blaster is a machine that mixes abrasive grains with a jet of compressed air and allows the user to abrade the surface of a part, usually metal.  This results in a clean though roughened part free of paint, rust, and other forms of dirt.  For smaller parts the blast gun is contained in a glovebox cabinet sealed off from the outside.  The user manipulates the tool with thick rubber gloves that pass through the wall of the cabinet.
* A2 tool testers (current or former)
* A2 instructors (current or former)
* Long-time shop or tool user


In a communal makerspace like Artisans it's essential to learn from the people above, as certain machines may exhibit idiosyncrasies which would not show up on a manual (if a manual even exists!). These people will also be familiar with shop dynamics and organizational challenges.
The sand blaster cabinet at Artisans Asylum is located in a small room within the Metal Shop on the south wall adjacent to the enclosed loading dock.


You can also ask the above users (i.e. shop leads) for a list of other known SMEs.
=Use For=


In the other category, there are potential SMEs who may be newer to A2 but with lots to contribute:
* Steel
* Stainless Steel
* Zinc-coated steel (Galvanized)
* Aluminum, Titanium, Brass
* Painted metal
* Lightly Rusted Parts


* New A2 member but with deep expertise in a process, machine, or tool
=Do Not Use For=


There are some pieces of knowledgeable which are universally applicable (independent of equipment) where these users can contribute to a wiki page. Their experience might come in the form of either hard technical chops or skillful intuition. They may be able to pick up on machine-specific quirks or perform repairs on their own.
* Lead-based paints
* Asbestos
* Greasy or Oily Parts
* Massively Rusty Parts


* Shop/tool users with little expertise, but lots of time/interest in contributing
'''Use a lead-test swab to verify that paint if NOT lead-based!'''


In this final category is a person with less existing knowledge, but potentially more time and motivation to contribute to a wiki. Don't shy away from working with them. These SMEs might be willing to read through a manual and learn by synthesizing that knowledge for others. They can also work with more knowledgeable SMEs and perform an important role of ensuring that instructions are clear to a novice user.
'''If the sandblaster becomes contaminated with lead the media must be disposed as [[TOXIC WASTE]] and the cabinet must be thoroughly cleaned out!'''


== How to work with subject matter experts==
=Safety Notes=


Some of the members above are quite busy and contributing to the wiki will not be a top priority. Someone may be willing to contribute and have a wealth of knowledge, but is slow at writing prose for whatever reason. This is why it is important to work with numerous SMEs. Some things to keep in mind which may help:

|-
| colspan="2" | 
|-
|}
* '''Wear safety goggles.'''  Eyeglasses don't protect against abrasive dust.


* Provide motivation for contributing to the wiki. Some SMEs (i.e. shop leads and tool testers) are used to people demanding their time to get up to speed on a tool or machine. A good wiki page should be a resource they can direct prospective users as a supplement to tool testing and as a way to prevent machines from being ruined (reducing downtime and repair needs).
* Wear a dust mask or respirator when using the machine or working in the room when the machine is being used. All dust is hazardous to breathe.


* Make it easy for SMEs contribute and take what you can. Some SMEs will never edit a MediaWiki page, but we can still get input from them, whether in the form of handwritten notes, a voice recording, or an email.
* Glove-box gloves are at a fixed height above the floor.  If they are too high, a stand should be provided.  Use care when stepping on and off the stand.

*  If the blast gun is not properly grounded to the cabinet, static electricity can cause shocks to the operator.  If static shocks are encountered, check the ground connection to the gun.
 
* Do not use silica sand as an abrasive media. The preferred sand blasting media is [https://www.grainger.com/product/Blast-Media-White-Aluminum-53YK23 aluminum oxide.]
 
* Use caution when lifting heavy parts into the sandblaster cabinet.
 
*  If a part is too large to allow the hatch to close and seal, then do not operate the sandblaster.
 
*  Use caution with the foot pedal and hoses.  They are a trip hazard.

* '''Test paints and coatings for [[LEAD]] using the test swabs provided.'''  The swabs change from yellow to red when lead is present.  If lead is detected do not clean with the sand blaster.
 
*  Do not abrade greasy or oily parts in the sandblaster.  These will case the media to clump and clog the flow lines.  If it happens, the media must be replaced.
 
* Place the workpiece in the blast cabinet and close the hatch tightly to avoid dust escaping from the cabinet.  When removing workpieces, some dust will unavoidably mix with the room air.  Wear a dust mask at all times.
 
* Do not attempt to move the blast cabinet when it is full of abrasive media.
 
* Do not point the blast gun at the rubber gloves or the cabinet window.

Description

A sand blaster is a machine that mixes abrasive grains with a jet of compressed air and allows the user to abrade the surface of a part, usually metal. This results in a clean though roughened part free of paint, rust, and other forms of dirt. For smaller parts the blast gun is contained in a glovebox cabinet sealed off from the outside. The user manipulates the tool with thick rubber gloves that pass through the wall of the cabinet.

The sand blaster cabinet at Artisans Asylum is located in a small room within the Metal Shop on the south wall adjacent to the enclosed loading dock.

Use For

  • Steel
  • Stainless Steel
  • Zinc-coated steel (Galvanized)
  • Aluminum, Titanium, Brass
  • Painted metal
  • Lightly Rusted Parts

Do Not Use For

  • Lead-based paints
  • Asbestos
  • Greasy or Oily Parts
  • Massively Rusty Parts

Use a lead-test swab to verify that paint if NOT lead-based!

If the sandblaster becomes contaminated with lead the media must be disposed as TOXIC WASTE and the cabinet must be thoroughly cleaned out!
