Carl’s Slip On Custom Centering Cones

I now use my "slip on" custom UHMW cones rather than the "threaded" custom cones featured in my 2007 AAW Journal "Custom Centering Cones" article.

Some times you look backwards and realize you had "blinders" on. In 2007 I was replacing the Oneway thread on aluminum cones with my own cones made out of UHMW plastic. Oneway threaded on there aluminum cones thus I thought I needed to thread on my cones. It took years, but I have seen the light.

Slip on cones are better! They are easier to make and they are easier to use. Why? Because, they just slip on! When you press them up against something with tail stock pressure they will stay in place on there own. You don't need to waste time threading them on.

Golden Ratio Calipers

I made a set of "Golden Ratio Calipers".

I like to use the "Golden Ratio" (1.618…) when creating hollow forms and wide rim plates. It allows me to create things with pleasing proportions found in nature.

The golden ratio tells me where the widest diameter of a hollow form should be relative to the top and bottom. It also tells we how big the bowl in the center of wide rim bowl or plate should be. Continue reading Golden Ratio Calipers
