Rotary-Dasher Box Churn: Float Boards on Crossed Arms in a Curved Box
An up-and-down dash churn is slow, tiring work.
Rufus Porter of Billerica, Massachusetts, received US 735, dated 10 May 1838, for a churn: a box eighteen inches long with a bottom curved from end to end; a wooden shaft running between a hollow cone and a pointed centre screw; two parallel pairs of rods through the shaft at right angles, carrying float boards parallel with the shaft — "what is termed the rotary dasher" — turned by a crank whose twisted tenon is pressed into the shaft and comes out when the occasion requires.
This rung compares his churn's sweep with a tabletop one, then prints the dasher, builds the box, and makes butter.

"Four round bars or rods, sixteen inches long and one inch in diameter, pass through the shaft; two of these rods are parallel, and about five inches apart, each being one inch from one end of the shaft. The other two are parallel to each other, but at right angles with the first pair, and three inches apart; the four bars thus constituting eight arms."

Take a food-safe storage box about 150 × 100 mm and 150 mm deep. Drill both ends on the dasher's axis, 85 mm up. Bed a plywood strip curved from end to end in its floor with silicone, as his curved bottom.

Let 500 ml of heavy cream stand until it reaches about 15 °C, checked with the thermometer. Pour it into the box, close the lid, and crank steadily; time until the butter comes. Pour off the buttermilk, add cold water, churn a few turns and pour off again until it runs clear; work in a pinch of salt and weigh the butter.

History and honest limits
History and honest limits
**Rufus Porter** of Billerica, Massachusetts, received US 735, dated 10 May 1838. His box is eighteen inches long, ten wide and eighteen deep, of boards three-quarters of an inch thick; the bottom, three-eighths thick, is curved so its centre is three inches lower than its ends; a lid with ventilation apertures fits a rabbet; the float boards are eight inches long and three wide. He gave the dimensions of every part.
**Honest limits.** A storage box and a printed dasher at tabletop scale stand in for his. FDM prints hold food in their layer lines, so wash well and replace when worn. Your times and weights are the result.
