- Spent more time reviewing the BOM lists and found many more updates. Called Surplus Center and they changed several items in the order before it was released for shipping.
I'll submit an updated order list when I receive it.Already updated.
- While on the phone with SurplusCenter, I asked them about couplings and gave them the shaft sizes for the Power Cube - they said it would come in 3 pieces and cost $52 total, so I added this to the order as well.
- Our experience with spider couplings and hytrel showed that they don't last more than 40-100 hours, so we went to solid couplings. The plastic wears out.-MJ
- OK - With that information, I cancelled the coupling from the order and will be going with a custom fixed coupling instead.
- Called a local vendor for hydraulic coolers and found a company here in Dallas that sells with or without fan and thermostatic switch. Looking at the photo made me think that if we used their fan, we could do without the expanded steel protecting the oil cooler fins - but at what cost? Waiting on reply from vendor . . .

- Spent time studying the documentation and design drawings for the LifeTrac tractor and compared them against the old BOM for steel parts. Did lots of updating and send requests for revision to the current maintainer - Will. Last correspondence said he is packing up in England and soon traveling to Factory-E-Farm in Missouri.
- Spent hours analyzing discrepancies between the BOM part list and the actual parts for the Power Cube - found lots of differences and made some adjustments for design updates and parts available from the vendor. Will update BOM tomorrow accordingly. Finally, got the first round ordered. Here is the order:

- Note that when searching for items, you must be creative. For example, a "Hose Barb" is sometimes spelled "HOSEBARB" and isn't found by searching for "hose" or "barb". Try multiple ways of searching or just call the vendor.
- Immediately after pressing the confirm button, I realized that I was missing a part or two, but that they should be easy to find in Dallas, but it will mean another trip to a vendor.

Since my return from the Dedicated Project Visit, I have been continuing my documentation efforts on the Power Cube. The documentation is critical when ordering parts and steel, as I want to have everything necessary, but not be short either.
I have also collected a set of tools for building Power Cubes. This video shows some of the tools:
- Tools collected so far
- Oxy-Acetylene cutting torch, tanks, hose, regulators, cart (Used: $400)
- Heavy Duty Metal cutting chop saw (Used: $125 + $20 to re-sharpen carbide blade)
- 1/2" Hand Drill
- 7" Angle Grinder ($70 at Northern Tool - 5 Yr in-store warranty)
- 4" Angle Grinder (Used: $30)
- Shop Vacuum (Used: $15)
- 3 pair Vise Grip pliers - to clamp metal for welding
- Socket Set
- 2 Crescent wrenches
- Face shield for grinding
- Eye protection
- Other tools not shown in the video include:
- TIG Welder
- Safety Equipment (steel toe boots, welding hood, welding jacket, hearing protection)
- Drill press
- Paint sprayer
Ordered Engine
Scoured the web for sources on engines and finally came across Small Engine Suppliers and ordered a suitable 28 HP model:
- Briggs & Stratton 49M777-various 28 HP Professional Series
- Order:
