How to Make Ice Cream Maker: Brian Smith, owner and instructor at Ample Hills Creamery, says hand-crank mixers keep you busy. “It’s what we use in our ice cream making classes. I love the community aspect of making it the old-fashioned way, taking turns.”
To make the ice cream, place a cup of rock salt and a layer of ice between a coffee can and a paint can. Pour the cream into the coffee pot and crank for about ten minutes or until the cream thickens to the consistency of soft serve.
Step No. 1
Cut the following sections to lengths of 3⁄4-in. Stock: Part B cut to 4 1⁄2 in. Cut part D to 2 inches; Cut sections E and K to 8 inches, and section H to 2 3⁄4 inches. (This will be cut into a parallelepiped shape later.) Finish by ripping part B to 7⁄8-inch width.
Cut the following sections to length from 1/4-inch stock: Cut section I to 4 inches, and section J to 2 3⁄4 inches. (It will also be cut in a parallelogram.)
Cut sections H and J to their full length in the shape of a parallelogram. Set a miter saw at 30 degrees and cut the sections so their long sides measure 2 inches.

The crank arm and dowel rod (B and C) are a subassembly. They operate the pedals (H, I, and J), a separate subassembly. But the trick is to allow the crank and paddle to rotate freely while supporting the mixing can. The solution is surprisingly simple.
First cut the dowel rod crosswise 7 inches long. Next, glue parts D and E together to form the crank support. Center D at length E
When the glue dries, bore a 1⁄2-in. The hole is centered on the width and length of these two sections. Now use an awl to mark the hole for the dowel rod (C) in the crank arm (B). Place the mark at arm’s width and 9⁄16 inches from the tip. Drill a 1⁄2-inch hole at the mark. Also drill the holes for the mounting bolts on the dresser knob (A). Its diameter depends on what you buy. You should position the hole so that its center is about 1⁄2 inch from the end of the crank arm. Attach the knob to the arm.
Glue the dowel into the crank arm, and glue the mixing paddle (parts H, I, and J) together. Slide the nylon spacer over the dowel, and slide the dowel through the crank support (parts D and E glued together), but do not glue it.
Cut a slightly oversized hole in the center of the coffee can lid (G), then slide the grommet (F) and then the lid over the end of the dowel rod.
Take one of the wooden blocks that will form part of the K and mark its hole locations. This will become the template for drilling the holes in both parts. Centered across the width of the block, use an awl to mark the two hole positions, 2 inches from each end of the block. Clamp the two-part blocks together and drill a 15⁄16-in. Drill holes in both blocks at one end, and at the other end drill a 1⁄4-in. holes.
Use a sharp pencil and a straight edge to mark the diagonal on the end grain of the top of these blocks (near the end of the 15⁄16-in. hole). Mark the center of the diagonal with an awl and drill a pilot hole at the mark using a 9⁄64-inch twist drill bit. Apply a generous coating of butcher block oil to these blocks, then turn the hanger bolts to their end grain, and allow the oil to dry.
Attach the blocks to the can through the holes in the top, then use a square placed along the edge of the can and the edge of the block to align each block on the surface of the can. Use the bottom hole in each block to guide the drill bit to make the bottom bolt hole through the paint can, push the bottom bolt through these holes and tighten the nut on each bolt.
Pour the coffee can into the paint can. Dry the paddle on the end of the dowel rod, and insert the paddle into the coffee can. Here’s the fit you’re looking for: The plastic spacer under the crank arm should rest firmly on the upper support, which should be supported by blocks on the side of the box. When you crank the handle, the paddle should turn freely just above the bottom of the coffee can. If not, adjust the pedal position accordingly. Glue the paddle to the end of the dowel rod and let the glue dry.
Finish the project by applying a generous coating of butcher block oil to the crank arm and pedal assembly. Allow the oil to dry thoroughly before making the ice cream.
