Today's volunteer: Joel - Project:Robot Arm

Topic 1: Gaming Corner

  • It's there and beautiful!
  • unfortunately the radio signal at the new location is poor, there are random blackouts (loud crashing noise)

Topic 2: New Bandsaw

previously on slack...

  • Discussion about getting a new bandsaw ongoing
  • Current bandsaw is on long-term loan and not suitable for resawing thick planks
  • Need someone to identify a suitable model
  • Financial constraints make immediate purchase unlikely

  • Criteria for acquiring new tools discussed, including financing, maintenance, and impact on the space and other tools
  • Agreement that a plasma cutter could be considered if the criteria are met
  • Previous focus on the welding area before considering a plasma cutter
  • Mention of advantages of a plasma cutter for building molds for Precious Plastic
  • Suggestion of considering a cored wire welding machine for advantages in the metalworking area
  • today's opinion: nice idea, but not a priority
    • the welding area is still not usable, which should be taken care of before the next diy machine
