Welding

Basic parameters:

Professional weld shops charge $60-75/hr around Missouri. That is scalable and replicable, but redundant in terms of paying overhead when we have onsite facilities.
One can hire someone. Welders get paid $18-27 (mean, top 10%) in Missouri. This is a cost-effective route compared to hiring a fab shop, if one has their own equipment.
Thus, with OSE design, designs can be fabricated.
Welder search - by reference.

time of 40 hours for LifeTrac can thus cost between $720 and $1080, as opposed to $2400 for the outsource to a fab shop. From here, take $20/hr.
7 hours for a set of piers @15 minutes each - $140 for welding.
Pile Driver - 8 hrs - $160
MicroTrac - 40 hours of welding - $800
Baler - 40 hrs - $800
Rake - 8 hrs - $160.

OSE module-based design is most effective.
Execution for CNC machines requires 3D printing, best done with D3D Pro 3 for larger prints.
Thus, design the following things:
- 3x geardown for OSE Universal Rotor with pile-driving attachment
- P2 pile - up to 10'
- Tractor - bobcat style life LifeTrac
- Microtrac - with mower, tiller, small round baler, rake, and cutter. Decrease track width possibly to 8" on both LifeTrac and MicroTrac.
- Mower - rotary disk
- Rake -
- Baler - simple
- Brushhog
