Howto

  1. Sand blast
  2. Base bath - 10 minutes min
  3. Base bath - 7 minutes min
  4. Flux - ammonium
  5. Actual dip - 3.5 minutes (until base metal reaches melt temp of 835F)
  6. Water - trapped water explodes, and is dangerous, so first dip is dangerous and venting must be assured.
  7. Zinc - 2400 lb blocks are the feedstock for hot dip baths. This is only 0.1 cubic meter - or 4 cubic feet.

Sourcing

  1. Acid -
  2. Base - KOH pr NaOH for grease - [2], NaOH doesn't require hot water.
  3. Ammonium chloride - $2/lb [3]
