Discussions - aka Review

Production Meeting - 9/18

• Still need instructions with loader arms -- but they are assembled
• Instructions completed for the turning pivot
• Logic of completing the wheel hubs: parts are prepared; need to assemble & weld -- Gary & Marcin will work on two, Gary copying what Marcin is doing; Marcin will generate step procedures in Google Docs
• Need to put the ground hug pivot with the power cube
• Lucas may be available after 6pm
• Need Marcin to finish the hydraulic schematics

Production Meeting - 9/17

• Gary needs to finish Loader Arm & Quick Attach instructions
• The cab and power cube frame is built;
• MoKan did not have 10" bolts--we are using temp bolts and will swap when the bolts come in, ETA Thurs, 9/19
• Design Issue: The bucket attachment is too weak; reverting to earlier version of design
  • Impact: James will integrate re-design
• Pivot instructions are done
• Need to grind down stands on the axle (cut about 1/2")
• Marcin will work on the wheel units -- need to ensure robust documentation of this process
• Tires -- we have 4; need to order 4 more tires -- Katie
• We now have "HabLab" modem in the workshop

DPV Schedule

Production Meeting - 9/16

• Completed: cutting of 4x4 tubing & bonding plates
• Need to finish cutting pivot plates
• Need to finish hydraulics schematics (meet w/Marcin)
• Katie is getting bolts from MoKan; we need inventory fasteners
• Marcin is picking up rims from Jason; may be able to pick up tires
  • Otherwise, we still need to source tires -- critical point for tires: Wed (parts in hand, then mount them)
• Gary is finalizing work instructions
• Need to separate steel into modules
• Need Marcin to put together quick attach mounts (welding) -- need deliberate documentation of this step for instructionals
• Need to update shop inventory

DPV Schedule

Production Meeting - 9/15

• To cut: 4x4 w/ no holes
• Update shop inventory (need wifi in shop!)
  • Call century link (Katie)
• Start quick connects
• Hydraulics schematics -- need Wed
• Tires

Logistics Requirements: To Do Sept 16

• Sweiger: wire mesh, sprocket
• MoKan: bolts; plus 90 x 10" zinc plated grade 2 bolts
• Jason: rims; tires?

Hydraulics

• September 13: The hydraulics diagram is good except it shows the motors wired in series. They should be wired in parallel. The series configuration shown will give us 1000 lb of pushing force, and the parallel configuration will give us 4000 lb of pushing force from our 30" diameter wheels.

• September 14 response: This makes sense. Are you asking for a new diagram showing all of this? No problem, but remember Rob's Fast, Good, Cheap Tiangle: You can only choose two.
  • It sounds like a good set-up, but then there will be no hoses running between the joysticks.

       Cheap - - - -  Good

Power Cube

• September 13: Note that the design is for one power cube only. If we use 2 power cubes - so we can run the pulverizer - then we need to connect one power cube to each valve, with the two valves being independent systems. This could by done if we route the Pulverizer and Loader Lift/Curl through the 3 spool joystick valve (first power cube), and the wheel drive/turning through the other valve (and second power cube).
  • This means that each valve must have quick couplers, so we can rewire the system for the 2 power cube case.
  • The bottom line is: fluid can't mix between the two power cubes, or it will begin to spill. Each power cube must have its own closed circuit, with no fluid mixing between the cubes.
