Instructions
Measure out 4 gal. of water and pour it into a clean 5-gal. bucket. The water acts as a coolant during drilling.
Add 3 cups of liquid dish washing soap to the water. Stir the soap into the water and allow soap suds to dissipate. The soap acts as a catalyst, allowing the water and oil to mix properly.
Pour 1 qt. of motor oil into the bucket. Mix the oil and the soapy solution thoroughly. The oil acts a lubricant during drilling.
