NEW File:LifeTrac4 CabLoaderArm.skp
June 25 through July 4th, 2013
Workshop! Projects included the construction of the dozer blade (1), cutting the slots for the spokes of the steel wheels, first with plasma torch then with a 9/16" bit on the mill. Note: when using a plasma torch in the extreme humidity of Missouri summers the water trap must be emptied every 30 min. Mill made a better cut and was actually faster as well. In order to keep the angle from pushing out of the vice we had to hold it down with a 2x4 which was C-clamped to the table of the mill. See photo below. We tried many other ways of securing it, however this jerry-rigged set up ended up best.
Also made the plate for mounting hydraulics in the cab, for up to four power cubes. This was done out of 1/2" sheet using the punch and die on the first ironworker.

Finished:
Then I made and mounted ribs for the dozer blade, custom cut to fit its new dimensions (will update those soon) out of 2x2 angle iron.
Then worked on drilling holes and putting together the boom for the backhoe:
I worked on welding the collars into the pivot plates. Then I assisted Cory and Lucas working on the pivot of the backhoe.

- Worked on converting the parts of the dozer blade that will need to be CNC cut ahead of time, including the pivot plate and mount as well as the ribs and bottom reinforcments, and the new plate for mounting the blade to the pivot:
- Fixed up the dozer sketchup more: expanded the ribs, made the plates for attaching the hydraulic cylinders more robust.
- Altered the mount of the dozer blade to contact: took out the vertical 4x4 tubing and now have 2 strips to mount, also shortened the plate that mounts onto the pivot:

- Completed rough design of Loader arm module with hydraulic pistons and quick attach plateFile:OSEquickAttach.skp:
- File:LoaderArm1a.skp -
- has corrected location, of arm pivots so it's not in way of cab.
- Fixed the pivot and hydraulic cylinder angles on the File:DozerBlade3.skp
Review, Aug 4, 2015
- It makes it easier if the rotation is on the tractor side, not on the blade side, to keep the complexity and weight towards the tractor.-MJ
June 12, 2013
- Began work on the modular redesign of the loader arms File:LoaderArm1a.skp. Still needs lots of work, look into sourcing and prices of larger bore hydraulic cylinders.
- After a discussion with Marcin, revisited the dozer blade to create the design for the actual blade as well as the mounting structure. Led to small alterations with the mount, but not much. Will need to do some minor adjustments and measurements on it tomorrow. File:DozerBlade3.skp

- Completed the conceptual design for hydraulic set-up on the dozer blade File:DozerBlade1.5.skp

- Long conference with whole management and design team to get bigger picture ideas on modularity and how what we are designing can be utilized in this model: see Chris DeAngelis Log for File:Machine module compliments.xls.
- Began work on the Loader Arm Module: File:LoaderArm1a.skp
June 10, 2013
- Started designing the hydraulic set up for the movement of the File:DozerBlade1.5.skp
- This design is based off the modular dozer blade found here:

- Hydraulic cylinder for angle:

- Hydraulic cylinder for tilt:
June 7, 2013
- Revisited the attachment for the File:DozerBlade1.skp, made a new way of joining the arm to the blade for movement in six directions. Here are screen shots of the preliminary designs:
- This is the more complete model. The dark blue pieces represent hydraulic pistons and where they would attach. This is still a sort of rough sketch. Measurements are not exact. However the central plate allows the blade to have tilt, while the pin attached to the plate gives it the forward and back angled motion. This design attaches the dozer blade to the LifeTrac (File:3DLifeTrac.skp):

Current ideas and designs found online for the Bulldozer 6-way Blade:
- This one is the most modular design with very compact and simple hydraulics:

- Detailed description of one style for mounting arms and hydraulic control (4-way):

- Good Specs on weights, heights, and angles for varying widths of 6-way blades:
http://www.freepatentsonline.com/7013983.pdf
- Began work on sketchup file for the blade File:DozerBlade1.skp, with a joint for 6 way motion.
- Having difficulty determining if this joint is feasible or strong enough. Trying to adapt the concept of a large bearing joint for the entire arm of the dozer blade attachment.
Here are some images of the joint:

- Corrected orientation of PowercubeFile:PTcube2.skp in design. Updated version: File:Microtrac preliminary.skp
- Altered Quick Connect Wheels and motors to fit the MicroTrac.
- Designed the hub attachment to fit wheel to shaft for both the 20" and 21" donuts at the shop.
- Began research on bulldozer blades in order to begin design process.

This is the microtrac frame with a powercube File:PTcube2.skp. Sorry its upside down, its just for size reference at this point. Also it has the Quick Connect Wheels and the wheels with tracks File:Micro fulltrack6 4.skp.

This is an updated model of the frame for the microtrac using the warehouse tubing found in the File:Warehouse.skp.
