Mech Work Session - LettuceMeet

Pegasus arm clamping block discussion

Open

• is the 4th bolt loose?

  • if its tight then something sus

• lock washer

  • mis-used - try lock washer

    • split: fully compressed - don’t apply axial force.

    • might just vibrate out

    • will probably just delay the bolt loosening process, but not prevent it

  • loctite a concern

  • nylock?

• how much benefit are we getting out of clamping blocks?

  • we believed vibe was the issue a long time ago

• only on the clamping blocks

• didn’t vibrate out of peek standoffs?
