    Restoring antique plow - need to remove rusted nuts/bolts - how much heat?

    Sometimes a Cold Chisel and hammer is just faster and easier. You just split the nut, or even take it right off. Not like you can really re-use the Bolt and Nut, anyway. WEAR GOGGLES AND GLOVES for this.

    Electric conversion of a Kubota B26 / Similar

    True. Part of why I am encouraging galstaf to consider a cord / cable option for this. Will also save a ton of money on the battery. Can build it with a little battery, and then add if he discovers he needs more. Covered part of this on this thread >>> Cord Management on Grid-Connected...

    Electric conversion of a Kubota B26 / Similar

    So how is this going so far? What are you finding and what are you needing? Can help you on the design and details, if you like. Sounds like you may do some stationary work? e.g., Backhoe, etc. If so, I would encourage you to consider a cord connection option, as well. So you move...

    Error in assumption for the start -- Actual "on the road" is down around 100 Million. Most cars (and trucks, etc.) are mostly just parked and sitting still most of the time. And in the case of EVs and ICEs -- if there is an EV around, it is the one that gets most of the "Miles Driven." Miles...

    conduit recommendation

    I like sealtite unless there is some heat or crush problems. Yunno some sealtite has metal flex inside (tougher), and some is just the PVC outside (cheaper). If you use the metal-lined I would make sure you have some sort of bushing, (or tape wrap) .. . . or even the correct end-fitting (omg)...

    Lotta study ahead. Frequency and waveform are even considerations. Personally, I would go with the Bumper Car system. Live ceiling and grounded roadway. And cars that just bounce when they run into each other. ;D

    ummm. Yeah. (speaking of paying attention :p ) Vehicle in motion. Coil ONLY turns on when vehicle is OVER the Coil. That way when no vehicle is over it, there is no energy required. We good on that part? The stationary stuff is a bit pedestrian, and now decades established. You mind if...

    Wealthy and Upper End are the main beneficiary of the Status Quo and "Defense" of US, as things are.

    The Top End Real Estate Leases (upper end Condos, etc.) are already putting in EV chargers as feature for their upper end tenants. Bottom End -- as usual . . . not so much. Until the Bottom End Landlords figure out they can charge the low income tenant a mark-up on the Electricity.

    Typical numbers for Volcanos are about 1% or less. The math is pretty clear. We know about how much Coal + Oil + Gas we (humans) have burnt into the Air. The increase in CO2 across the last 200 years is just about that. Does not take Columbo to figure this one out. Nice thing is that...

    Push Mowers, Battery Vs. gas

    It is a Single Phase to 3 Phase converter. The motor on the old mower deck is a 3-Phase industrial motor. All Rather Olde Skool. ;) It is a Face-Mount motor, held on the deck with Unistrut, and the mower blade just mounts on the motor shaft. Most of the time the converter just sits in...

    Never stalled one, that I recall. Have "stuck" some tractors -- generally Mud or Sand. Worst I recall for that was having to drop a plow, pull the tractor out (with another tractor), and then chain pull the plow out backwards to get everything back on solid ground. I suppose getting stuck...

    Mind if I pick your brain on this? Not trying to debate things -- but more the downside / no faith part. I am doing some Electric Designs . . . Sort of trying to do a things-that-suck sort of list -- to avoid or do design-around. Thanks!

    Dunno, overall a little drama goofy for me. But to each their own. -------------------------- But the all-in-this-together part . . . yeah when it comes to the Commons -- that is definitely the case. The "Common" Water, Air, Land -- all pretty much eternal from a human perspective. And...

    Yeah, so you follow that the measuring of unit of "plants" has no real meaning? Some sites or plants have only 1 reactor, some as many as 6 or even one has 8, irrc. So we take the number of reactors x the typical reactor size of around 1E9 (some are a little bigger), and we can get the scope...

    Does not turn out that way -- as far as the Nukes. Only thing 250-300 nukes would get US is Broke. At this point we have under 100 US reactors and dropping, and many of those are not profitable. We will probably be down to about 50 or maybe less of the existing by 2050, with few-to-none...

    Talk what way about the Amish? I grew up in a mixed Amish-Mennonite-"English" farming area. Still have friends and family in that area and doing those things. Nothing pejorative about it. I am saying that a few folks doing something does little harm. Many folks doing something may be...

    Things are not moving so fast that you are likely to be effected in your life time. For the rest of US -- it is something a "Tragedy of the Commons" thing. You familiar with the "Commons?" It is a concept of shared resources. Since anyone can take from or dump in the common areas (shared...

    Sort of odd, but some folks get some (not much, but some) Solar PV in Alaska from a Full Moon during the Winter along with reflected snow. Internal resistance of the Silicon Solar PV goes down in Cold Weather, so deep Alaska nights allow this.

    Best Steering / Frame / Tractor Combo -- for Robotic-Electric.

    :P Yeah, it does sounds rough, but with just 8-bit control -- and usually using the first bit as Forward or Reverse -- that leaves 7 bits (or 128 levels) for speed adjustment. So when you tell any given motor which direction to go, it might be [1xxx xxxx] for Forward, or [0xxx xxxx] for...

    Best Steering / Frame / Tractor Combo -- for Robotic-Electric.

    Thanks. Also you have the ability for the connections between the front and back section to swivel -- so all 4 wheels stay in contact with the earth on un-even ground. I figured I might try to avoid that feature to start, but maybe I should do that, as well, as it will put less stress on the...

    okay. I follow the pivot bearing is straight up and down -- but what about the ideal angle between the center bearing of the wheel, and where the bottom of the pivot is attached? sample pictures >>> Caster - Wikipedia

    SUPER. Let me go down your list? So for making this discussion practical, let me tag the tires? Front Left = FL Front Right = FR Rear Left = RL Rear Right = RR ================================ Now the tricks each motor can do. All the motors are controlled by Variable Frequency Drives...

    Best Steering / Frame / Tractor Combo -- for Robotic-Electric.

    Great question. Since this is not really a road type vehicle -- I was planning on just letting it slip. Any real "pulling" will likely be in a straight line, and then no differential is really needed. For a relatively "light" vehicle do you think this would be a problem? I could use (4)...

    Next up . . . . So that last one was the Zero Turn. This one is the Articulated (Folding or Hinged) Frame. Still has (2) Drive Motors -- but now is 4 Wheel Drive. That seems like quite a productive improvement. Adds a Steering Linear Actuator -- sort of works like a two-way piston -- but...

    Off grid solar system design help?

    if you would like some fairly exact numbers, maybe take a look at the NREL (National Renewable Energy Lab) online calculator program called PVWatts. The have a 30+ year database across the US and points beyond. It uses your location, equipment type, install angles, direction, losses across...

    Off grid solar system design help?

    mkay. Usually we look for 3 things: + Open Circuit Voltage -- point at Sun and measure Volts across the leads. + Short Circuit Current -- (we do this, but only a maybe for you) -- make sure the Amp Rating and connections on your meter can handle the current -- many have a fuse and Max of 10...

    Electrical / romex mess

    Is that Romex (trade name for NM --Non Metallic Sheath Cable)? or is it UF (Underground Feeder)? In general -- UF can be direct buried, Romex/NM cannot. NM / Romex usually has a paper fill, UF is solid plastic fill. UF can be run without conduit, but the extra protection is always nice.

    Are you doing good on your design, now? Need some more review? For "lite" 120 / 240 Volt Loads -- like say a notebook computer, or a wifi for internet -- various little inverters, typical small portable car and truck types, generally work pretty well. That way you can keep down the...

    Electric Rototiller Details -- Review, Comments, etc.

    My next look-ahead is the Chain Drive. (this is the musing of an Electrical Guy wandering deep into Mechanical -- so please correct me if you see errors or cautions) I guess I noted that I have some surplus 5 HP 1200 RPM Motor(s) for this. Nuisance on that RPM (1200) is it is a 6-pole, and...
