Notes

Michel system admin, working on installing our own email server, jitsi for better connection and free
Tech for Trade filament extruder is better than lyman, but hopefully they can change license to not only CC by NC
CNC Torch Table: working on some bushing adjustments for easier alignment
Solar power cube
GPS controller for tractor maybe, but using rasberry pi currently
Brick press build out at UofUtah
Tractor build in just over two weeks! (Josh and Lex will be there)
Open Source Nesting for flat pattern cutting
FreeCAD best practices and sample parts
Vibratory trencher development is underway
Bucket attachment for tractor

Notes:

OSE Linux testing: issues

Discussion about specifications of the minitractor design, while showing the CAD File.

Focus job on the tractor, current state of the tractor.

Not technically acurate:

Motor is up,

Mounting plate is not correct

Path array draw a line, etc. (FreeCad knowledge)

42 inches

Make 9 inches the tracks

Tracks are not lind out with the idlers

Shaft is looking good….

20 inches height of the power cube…

Shaft goes the whole way to hold loaders

To Do: make a Geometry to put the loader

Because the tracks are so height on the back there is not so much space,

Requirement: put the center of gravity as low as possible

Missing the idlers: need to be tensioned

Put a shaft through the middle of the frame or under the frame, or through the frame;

Mount two motors so that : assembly mount the motor on some ckind of a plate against the vertical so that …lower the sprocket all the way down, take a pin and then connect the track,

34 tracks; put 40 , sprocket is sticking too much..

Bobcat standard

Next Steps:

Promo video October 30; still doing the filament maker

Experimental torch build; October 14 -15 Saturday Sunday;

Change in the setup of workshop, 1sst half day, focus on manipulating freecad and generate drawings

Heavy duty: 200 pounds milling/ force, belt drive for heavy duty machines.

Calculations indicate that is possible that you it can be slower,

But speed of machining throughput, produce 1 per day…. Low Volume production

This is the value proposition

Previous build: heavy duty drills…Main take away: We know how it works, use hydraulics for the heavy duty motors, and stepper motors for the drives on the axis,

200 pounds per inch of belts, duplication or quadruplication of belts, using the same universal axis…. Core technology universal Axis…

New workflow to generate full exploded views…

Roberto: This procedure is easier

Problem quality of the image,

It should be possible to improve the image quality

Workflow for importing assemblies

Is the power cube and assembly or separated in parts;…

Keep it as a one part;

Gasifier: Talked to someone: We are still planning for gasifier, smaller version with better carburetor, click to see the notes, print in ceramics. Printing clay, Print the core of the gasifier, is a very high temperature carbon monoxide, charcoal is the fuel, it burns… is very high temperature….

Discussion about the OSE linux:

Questions/Comments

Would best Practices for CAD on the wiki be helpful for people?
Changing the motor mount bolt holes to slots (horizontal?) is the only easy way I see to add adjustment to tension the tracks. This may require significant torque on the mounting bolts. So can the motor body steel support the enough compression without stripping? And the bolts need to be a grade such that they don’t break off easy if over torqued.
Also there are some dimension changes assuming a switch from ¾” plate to ½” plate. Do we need any ¾” plate parts? I think cutting everything out of ½” is best and strong enough. For instance the track rollers and spacing of the links. And the existing drive motor sprocket and body is not easily editable yet. I see the sprocket geometry is scaled to roller size, but the thickness is ¾” now instead of ½”plate.
The Sprocket also needs plates welded to the sides where the track links ride; ½” plate should work assuming everything else is ½”.
