Top-Shell painting process

EtcherPro v1

Step 1 prepare for painting​

  • Turn on the Fume extractor
  • Turn on the Ventilation Fan
  • Make sure that the valve underneath the compressor is tightly closed and not losing air
  • Turn on the air compressor
  • Check that the air compressor is set at the proper pressure(2.5-4bar). To adjust the pressure, turn the red knob attached to the pressure gauge to achieve the correct pressure.
  • Assemble the painting air gun
  • connect it to the tube installed in the air compressor
  • Make sure that the EMC water-based paint is always thoroughly mixed before using it. Use the metal jig attached to the BOSCH screwdriver
  • Have a plastic bottle with ¾ full of paint for easier filling the air gun’s cup. Shake before using

Step 2 Painting process​

  • Wear a mask and safety goggles
  • Always use disposable gloves before painting
  • Fill the spray gun’s cup with paint halfway
  • Apply pure alcohol to a paper towel and clean the top shell from the inside to remove unnecessary oil or dust
  • Place the Top-shell upside down on the modified jig, with the slots facing away from you
  • Modified jig
  • Place the carton ring covering the inside of the shell and surround the outside part of the shell with the nylon protective curtain
  • Carton ring
  • Place the plastic jig above the slots, with the wooden sticks pushing against the carton ring, making sure all slots are covered
  • Plastic jig
  • Start applying multiple thin coats of paint, thoroughly covering the exposed areas. The applied paint should look wet but should not drip.
  • Check if all exposed areas are properly covered with paint
  • Remove the slot cover carefully as the paint is still wet
  • Remove the carton ring carefully without damaging the wet paint
  • The first modified jig will be still wet so use the 2nd same modified jig in order to repeat the process while the 1st dries out
  • Place the Top shell in a ventilated area to dry, facing upwards (default orientation)

Step 3 finish painting​

  • Pour remaining paint back into its original can (if any) and make sure it is shielded properly
  • Disconnect the painting gun from the tube
  • Untighten the valve underneath the air compressor to release the air inside
  • Disassemble the painting air gun and wash thoroughly
  • Let the air gun dry keeping the parts unassembled
