Modules

  • Added inserts to the remaining top cell holders + top covers

  • Potted busbars for another cell holder, but ran out of busbars for more (waiting on the dwg file so we can cut another batch)

  • Measured cell voltages for another module's worth of cells

  • @Nicole Choe and @Taylor Elena Avery Hazelwood worked on enclosure jig manufacturing

  • @jenna k was working on CAD for aux. finished except securing mechanism needed to baffle, probs bolted connection

Enclosure:

  • Progress made on manufacturing modules. Manufacturing modules, but ran out of busbars - Vaibhav to message Caleb, who was in charge for water-jet files to forward the file to the group

  • Steel Flat Jig was tested and fits to chassis. Taylor cut 3/4 wood pieces needed for our enclosure jig, and I've asked her to cut holes for two of them. To be completed by Saturday

  • All screws set aside for Enclosure jig.

  • Tested another 32 cells for the module

  • Welding deadline for steel flat to enclosure is November 15th. Waiting for angle irons (hopefully in by wed 8th)

  • Enclosure panel MDF cutting needs to be redone - to be completed by Wednesday's working session (November 8th)

  • As soon as the angles arrive - Jenna to send a message @channel so machining can start as soon as possible.

  • 3D Prints to be assigned by Shem, after his Enclosure Design meeting with Jenna

 9 Nov 2023

  • Finished milling steel flats, cut to-size +- 0.4mm (outside XV-BAT129 Steel_Cross_Bar cut -0.9mm). This issue will be fixed by welding. Disregard yesterday's 2mm undersize, that was a mistake

  • Finished cutting angle irons - will be milled to-size by tomorrow 

  • Worked with Machine Shop Guy to plan cutting holes into parts using mill - will finish tomorrow

  • Validating Chassis Cross bar jig tomorrow by milling holes into a scrap 1/4" piece

  • 1/4" Steel for Chassis Cross bar has not arrived yet. Will ping when metal arrives

  • MDF for the enclosure jig is all cut! Thank you so much @jenna k

Note that WE DO NOT HAVE ANY EXTRA MATERIAL. I'd rather you guys make 3 perfect parts than make 8 parts that are bad. Quality first, we have time on the weekend if need-be

***Just an FYI, the holes for drawings 132 and 133 are pretty critical so be extra careful to be within tolerance with those! - Shem (edited)

Tho worst comes to worst we can just make the holes bigger if it does come out of spec and we run into assembly issues
