Needed items:

▪ Chris M brought-up light sensitivity and the lighting sources need to be controllable

  • Way oil - We are low/out
  • Bench vise brought up:

▪ Proposal was dismissed due to the observation that it is a heavily used tool was found to be a random high-use situation. For the most part the vise is underutilized
