The new sand blaster in the hot shop has been refurbished by Larry Meeks and Steve McHugh.

Basic instructions for using the sand blaster:

  1. Plug in the two cords in the back of the sand blaster (this requires crawling behind the sand blaster and plugging in cords on the north-facing wall).
  2. Connect the air compressor hose to the sand blaster.
  3. Empty the water trap (the plastic jar under the water valve) on the sand blaster.
  4. Plug in the air compressor, unplugging the powder coat oven if necessary.
  5. Flip both valves on the air compressor.
  6. Turn the switch on the air compressor from Off to Auto.
  7. Sandblast, using the foot pedal, for up to 20 minutes. After 20 minutes/releasing the foot pedal, all air is exhausted and the air pressure drops below 40 psi. The blaster automatically shuts off the grit flow, and the compressor stops running noisily.
  8. The sand blaster needs to be above 40 to maintain the blast, so take a break if necessary, wait another 20 minutes, and then resume.
  9. After using the sand blaster:
    1. Turn off the air compressor.
    2. Disconnected the hose and coil it up.
    3. Empty the water trap.
