Level 2 badge used at Pikes Peak Makerspace

The Powder Coating Area within our Metal Shop at Pikes Peak Makerspace (PPM) consists mostly of Level 2 equipment.

Additional PPM training is required to use any of our Level 2 equipment.

All of our Powder Coating Equipment combined occupies about 90 square feet (6'x18').

Sandblasting Area hand tools should be marked with pink tape, paint, or powder coating.

Contact Us if you cannot find your answer here on our Wiki or if you notice any information that is outdated.

 


Safety First

Members must know the following information:

In case of emergency, call 911.
Our physical location is:
735 East Pikes Peak Avenue
Colorado Springs, CO 80903
use this when ordering pizza or an ambulance

PPM Fire Escape Plan

Fire Escape Plan maps are posted throughout the Makerspace.
There are 7 fire extinguishers on the fire escape plan map. Review the PPM Fire Escape Plan for locations.

First Aid

There is a FIRST AID Supply Cabinet in our Kitchen Area.
FIRST AID Kits are available in four areas: the Kitchen, Metal Shop, Wood Shop and CNC Room.

Eye Wash Stations

Emergency Eye & Face Wash Stations are mounted in four areas: the Kitchen, Wood Shop, CNC Room and Vented Room.

Personal Protective Equipment (PPE)

Wear protective equipment in all Wood and Metal Shop Areas.
Wear gloves when using Isopropyl Alcohol and other cleaners.

Hazardous Chemicals

All hazardous chemicals must be stored in the yellow hazardous chemical storage cabinet located in the Vented Room.
Review the Safety Data Sheet (SDS) information of unknown products before use.
SDS information is available via the QR code on the hazardous chemical storage cabinet or this spreadsheet.
Do not bring dangerous chemicals to the makerspace.
Spray paint, stains, and other approved items must be stored in the hazardous chemical storage cabinet in the Vented Room.
Please DO NOT paint indoors.



Impairment

The use of PPM equipment requires you to be alert, attentive, and focused.
Do not use any PPM work area, or any PPM tools, if you are under the influence of drugs or alcohol.

Sandblasting Safety

  • Wear respirator
  • Wear eye protection
  • Do not use sandblaster with the door open
  • Using abrasive media with silica without a really good respirator will damage lungs

Sandblasting

Part prep

  • Clean all dirt and grease and oil off parts before blasting
  • Use tape to cover any part that you don’t want to be blasted
  • Use plugs or bolts to cover holes where you don’t want media to enter

Blast cabinet Prep

  • Check vacuum filter and cyclone before use and empty and clean if needed
  • Load abrasive media needed for the job
  • Set correct psi for the abrasive media loaded

Changing out abrasive media

  • Place container under cabinet and open bottom door
  • Brush off any media left inside on the sides into the container
  • Vacuum any media left
  • Empty cyclone and vacuum and blow out the filter
  • Store abrasive media in an airtight container or throw away if no longer good
  • Close bottom door and pour new media into cabinet through side door, 50lb max
  • Media must be dry
  • Put abrasive media tag on cabinet

Sandblasting

  • Place prepped part into the prepped cabinet and close and latch door
  • Flip on the power switch to turn on lights and vacuum
  • Use steady side to side movement when blasting
  • DO NOT stop and blast in one concentrated area for any long period of time as it can warp thinner panels and remove too much material on some surfaces
  • keep your nozzle at a 60-45 degree angle and aimed in the direction you are moving when blasting
  • If blasting gun sticks on turn off the air and remove the nut on top of the gun, remove the pin and blow out, and reassemble
  • Blow off the part with air before removing it from the cabinet

Abrasive Media

  • Media has a life span
  • Some are single-use and some can be reused many times
  • Using the right media for the part and correct PSI can extend the lifespan of media
  • Used media is like used sandpaper and loses effectiveness the more that it is used
  • If blasting is starting to take longer it is time to replace media
  • Harder and round media last longer
