A 10 horse power mill will do dryer and electric range cords but you still have to cut them into 6 inch sections, 14,12, and 10 gauge house wiring along with automotive wire with ease. Would not try transformers these would break the screens.
Probably won't chew up copper pipe larger than half inch, again short pieces no longer than 6 inches on the smaller pipe.
If you have neighbours in close proximity they're bound to complain about the unusual noises coming from your property.
Ten horse power is the largest electric motor you can run on single phase, inverters or roto-phase is required for larger motors on single phase power.
You can make your own roto-phase from any three phase electric motor that has 220/440 on the specification tag if the motor is not wired for 220 you must do this in order for it to work.
There are schematics using capacitors to start your home made roto-phase but I do mine on the cheaper side and use a small single phase motor to get the larger one turning over.
Two of the electrical inputs on the rotp-phase are wired to your 220 service the last leg is wired to your 3 phase motor giving you that 3rd phase the other two are wired to your 220 service.
To start the roto-phase start the smaller motor, this can be coupled using a lovejoy, now that the roto is turning switch on the 220 power then switch off the power to the small electric motor your roto-phase is now running on its own - generating 220 volts on that third leg which is now wired to the 3 phase motor you want to run.
With the power terminated at the small motor being that it is coupled via the lovejoy it will coast along with the roto-phase harmlessly until needed for the next starting procedure.
If the 3 phase is running in the wrong direction, switching any two wires of the three will change direction.
Sounds complicated take these instructions to an electrician buddy who will draw you a diagram of the wiring you need to do and how it works.
A three phase motor has three sets of coils, each coil is wired to a service that provides the three legs of power in order to run as a motor. Feed power to only two legs the motor needs assistance to start then it will run on the two supplied legs of power generating power from the third which now is used to supply the third leg to the 3 phase motor wish to run.
Just remember that the motors are both selected to operate at 220 volts and not 440.
