« Part 1: First half Part 2 of From ball to the star inside dodecahedron series no next part

I’ve been trying different approach on making plugs to hold peaces together. In the end, I’m down to two products: rubbery silicon and epoxy clay. Both keep size after drying (most important property for me). First I made new “cups”


Here is the small ball 1.5 inch diameter, possibly my next project. Both covered with oil


Epoxy and two layers of fabric (doesn’t need to be strong for now)



Carefully insert dull thin blade and slowly peaces will come apart


Package


Mold was poured into the fiberglass fibre cup and ball was pressed down


Next day, cup is removed


This is how it looks. Very soft on touch.


Because i mixed to much, i decided to make a mold of the old plug

I start looking for something harder then silicon:

Package


Two plugs after drying. Sanded to ball shape


Comparing silicon and epoxy


Plugs removed from the ball


I’m making two more plugs from epoxy clay


Back to the ball shape

—-
I’m going to use five epoxy and one silicon plugs. But from now on I will be making epoxy clay plugs only. It’s big time saving, can be sanded, drilled, turned. Result is “cleaner” and better then wood-wax, silicon, pure paraffin, etc. Just remember to oil the wood.

This is a great solution Yuri, especially for this type of turning.
