Thank!
Small tools to make this big equipment.
Everlast 275 amp inverter welder, it has fallen on the heat shields several times (on nonstop passes over 12 feet in length) Spool gun for Aluminum with possibility of pulsation. By having significantly more duty cycle, I would need a welder on the three-phase (575volt) but there is none on my street ...
Mastercraft 120 amp inverter welder, I didn稚 think I would use it that much for this project, as the 275 amp was mounted with 0.045 wire, I used the 120 amp for small parts, hydraulic fittings, exhaust. With wire 0.0.35. The mini gun and small cable without hose for the gases can be handled like a soldering iron for electrical circuits!
Small belt-driven tabletop milling, it has drilled thousands of holes up to 5 inches (hole saw)
17 鋳 2 speed lap only, tough enough for its size, but I would need a 36 知inimum.
Home made hydraulic press, on 12V hydraulic pump, approximately 25 tons with a clearance of 48 "to place parts.
14 "band saw for wood ... I installed 4 stages of speed reduction to have a suitable speed for steel. Reinforced in a few places.
The Evolution Nail Saw, the only difference with a standard wood miter saw is that it spins at 3,500 turns instead of 5,500 turns. Much faster than an abrasive saw. Its durability surprises me because I cut tons of steel with this inexpensive saw. I must have worn more than 100 blades. Cermet tipped blades last longer than others. Also Hand-held Evolution circular saw (skill saw)

I had 3 months maximum by evenings and weekends to build the excavator. Now I have to put it away for the winter. There is a little finishing, fans to install and then try it! I have projects to start and finish quickly for other people. Also with the movement restrictions for the covid (I don't have a hole to dig on my small lot). If I had not had to prepare the diesel engines (clean, supports for all these components around, engine supports, pump supports and several troubleshooting tests) Then then transform everything to adapt the Honda engine. I would have saved a lot of time. No tests for this year.

Snob,
You can bring it down here for the winter and it's final tests/changes. I have plenty of space to dig.
hugs, Brandi

Good thickness HDPE plastic body panels, they will not paint off, will be less prone to vibrate and have a rubber edge all around. They can all be removed quickly enough for maintenance or cleaning
Motor mounted on rubber and spring. However, components with the potential to vibrate have it all! rubbers and / or Silicon in addition to screws or bolts, no vibration noise.
Small platform on the back cover to transport some accessories (this is a space usually lost on excavators) A panel rises to have quick access to checks (oils, air filter, etc.)
Ideally I will put the tow wheels 2 "lower for more clearance on uneven or soft ground like here. I still have the removable rear panel to make with the road lights. There are 400lbs on the hitch so it’s ideal for towing stability (around 12% hitch weight)
All valves and indicators and knobs are within easy reach The sitting position and joystick valves are perfect for someone of average height.
The speed of movement of all cylinders is adjustable from 0 to 12.7 GPM, so you can always have the ideal speed depending on the job at hand. On the video (I wasn't the one sitting on it) the speed was around 4 GPM and the engine was less than half RPM).
The 2nd pump provides an additional 2km / h at the push of a button which is located on the pull valve levers. So ideally we engage the first pump (0 to 12.7 GPM) before engaging the 2nd pump (6.3 GPM) for a less abrupt start and stop (that's not what I did during sudden stops)
Tight for winter (time elapsed) There is still some finishing to do, among other things, a panel behind the seat and the fans.

I love the paint job. The quick attach "trailer" is just mind boggling. Easy to tow. Have you towed it yet?
