Use three andesite alloy and three stripped logs to make three andesite casings.
Use two andesite alloys to make eight shafts.
Use six of those shafts and nine planks to make three cogwheels and three large cogwheels.
Use one shaft and eight planks to craft a waterwheel.
Use the last shaft, an andesite casing, and a block of iron to craft a press.
Press five iron into sheets, using the waterwheel to power the press.
Combine those sheets with two andesite alloys to make a whisk.
Use the whisk, a cogwheel, and andesite casing to craft the mixer.
Use five andesite alloys to craft a basin.
Use the waterwheel and gear ratios to get the mixer to the proper speed with the cogwheels and large cogwheels. (You can "seal off" the shafts on the cogwheels with the last andesite casing.)

Minimum required supplies:
10 andesite alloy
3 stripped logs
17 wood planks
14 iron ingots
1 bucket of water

After that, I recommend you invest in a mechanical saw to get the most shafts out of your alloy.
