Discussion

Needed items:

  • #2 center drills
  • Lighting

▪ Tim proposed gooseneck lighting

• Questions:

• Do we want the color spectrum to be towards the yellow or blue spectrum?

▪ Chris M recommends more diffused light sources

▪ Randy recommended 4' light bars over the lathe

• Calvin brought up Costco as a potential source for low-cost lighting. Calvin stated it worked extremely well in his garage

▪ Concerns over the lights being UL listed was brought-up - MUST BE UL LISTED AT THE SPACE!

▪ 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

Future Workday Tasks:

○ Stop clamp (part that stops the automatic motion) on the Colchester lathe

○ Clutch index plate, for the Colchester Lathe. Lever for engagement.

○ #26 & #27 O-Ring for the transmission, for the Colchester Lathe

The demonstration separation wall is erected to show the desired appearance and stability
