I have an old hand drill. Would you like to change it into a reversible one? Specific how to change, please help tell
Conversion costs and wages add up to hundreds of dollars, rather than to the market to buy a machine, only 100 yuan, ha ha!
Positive or reverse, a converter can be used to switch the two wires of the carbon brush, and change the excitation direction. But when the reversal sounds very loud, sparks larger, as drilling and tapping machines, it is not practical.
The theory is feasible, but the actual operation is very difficult and not practical. I have changed it.Speed control can be connected with a variable resistor, but it is bulky and inconvenient to operate.
