Thanks for the help.
That answers my question.

Sometimes the best way to get where you want to go is by going somewhere
else. Think outside the sphere.

Thanks Again all

Greetings all,

I would like to make my own rubber stoppers I have created a mold
using
plaster of paris,
I have tried epoxy and fiberglass resin but these end up being to
hard
does anyone know
what I can use to make softer rubber stoppers.

Well, if you want to make rubber stoppers, why would you ask in a
glass group?

But since you have asked, and we already know that epoxy won't make a
rubber stopper, and neither will polyester resin. Odd, I don't
remember either of those being rubber to start with... why would... oh
well.

To make your own stoppers, rubber stoppers, you start with ...rubber!
The easiest for the layman to get his/her hands on is RTV or Silicone
rubber. Varying degrees of hardness will result from these synthetic
rubbers, and there are varying hardness within each category. I would
suggest RTV.

DO a google and look at Dow Corning series of RTV rubbers, they are
readily available worldwide, variety of hardness level, and easy to
work with 2 part mix. you mix what you need, save the rest. Make
your mold out of plaster of Paris.
