Dynamics Machining Plans (no welding included OR spares)

All Parts Needed:

Unsprung Timeline:

hubs x2
- will dedicate all my time to this 11/13 onwards after i grind out frame pucks
- cam done w/ endmills ordered 11/8 - @Harshit Dalmia
- IF WE GET SHOP ACCES ON 11/15
  - First hub turned by 11/15
    - harder bc needs to be precise asf for bearing seating, which is done on lathe
    - combustion letting us borrow internal micrometer for this (only me/harshit as of rn)
  - 2nd hub turned by 11/17 by latest 11/18
- first CNC done on 11/19 afternoon
- second CNC done on 11/21 or 11/22 workday
axles x2
- andrew to teach this / prob do himself for one of them at least i think, like he does one while teaching and then watches as sumi / diego does the other one
- start 11/10 learning single point therading (idk if andrew has done this yet)
  - hopefully done by 11/11 bc this will also determine how long the thread relief needs to be based on skill level tbh, and longer one means marginally longer axle so yeah
- axles currently BLOCKED by upright sim, so need to get sims done ASAP
hubnuts x2
- mcmaster :/
uprights x2
- sent out day the axles r done w/ bore’s dimensioned to how the axles’s turned out IRL
- caliper mount
  - can do in house, but lowkey just send w/ upright order
- pickup
  - can do in house but lowkey just sent w/ upright order
- steering mount
  - can do in house but lowkey just send w/ upright order
front rotors x2
- sent out 11/6
rear rotors x1
- sent out 11/6

Steering Timeline:

column tubes:
- all look to be 1” OD and probably already bought the nomal ID as well (i hope)
- drilling holes will take like 2 hours for all colmuns
column inserts:
- will be hard to drill holes into but not the worst
- 4130 so will be a hot sec to make on lathe but can do all in workay (I did one in < 1 hour in may)
u-joints
- if no come with holes, will take a bit to workhold + edgefind + drill holes for ujoints. maybe a workday thing
bearing housing
- idk how the stock is ordered for this. is it already nominal?
- grooving takes long time bc you need to indicate the rotary table + make an insert to indicate the part
  - i will explain this more in person but this will take like a workday
  - we should do this when we have the upper ca same time so we can ask jamie if we can leave the rotary table setup for a long period of time (a few day) so we don’t need to re-indicate every time
pillow blocks
- scs, then post-machine holes
  - should take a few hours
clevis/rack stop
- honestly oursource from jiga, we would need to CNC to get all those fillets w/ ball nose endmill, and the countersink is a pain, also the curved part on the inside is hard to do bc you need to sideways cut w/ an endmill
tire rods
- size up to an OD you can buy and then tapping + helicoiling should not take more than an hour total

Suspension:

bell crank plates:
- scs w/ new load cases locked in
pushrods: size to nearest od you can but and then tapping + helicoiling takes < 1 hour
upper apex: outsource
lower apex: scs, bore out hole w/ shoulder, groove
- need to redesign to have NO step down (bigger upper ca tube)
- needs locating feature for the tubes for welding
rear shock cup:
- i think bc of the weird ass curve u need to make more contact to the shock you need to outource (if its still like this)

Trailing Arm:

need inserts done
- can’t scs this thick so you need a way of getting the cirves, maybe just grind if its not that deep? if so then jiga
- also you need to then bore again for step down then groove for ret ring
momo
- outsource as soon as t-arm is passing
