So sorry to confuse you! My photo was to show how I made a wooden dowel as a “marker” to show what groove slot I was rolling in …My Cavallin mill did not come with one, and I kept seeing them on the Durson mills…
one day, this idea came to me…to make one and then “tension fit” it into the base using a thinner wooden dowel,as I always wondered how I could “attach” one to my mill if I would one for sale somewhere…(my not knowing how I would ever drill bolt holes into my mill!)
