I was looking for information on silicone molds for my rhubarb leaf concrete stepping stones when I came across an inventive individual who made a mixer to mix small amounts of concrete with part of a coil spring from a car.
I did not have a coil spring on hand but had some 7/16 inch hot rolled steel rod left over from helping a friend build a djembe drum stand. I just bent a 90 and then heated the rod and eyeballed a coil at the end. It works great in my 1/2″ drill, but I coiled it backwards so the drill has to be run in reverse. This just seems wrong to me.
If enough people are interested in this tool I could give more detailed instructions orĀ manufacture some for sale. Leave me a comment.
