Thanks for the kind words and constructive suggestions. I too use
RTV for a lot of my molds. I show my procedures for RTV on our
I have been using photopolymers to create my some of my models and
the button we created for Lily is a good example of the polymer
technique and RTV molding procedure we use.
I am not familiar with the, "platinum cured silicons" you refer to.
Ahhh, "where is the finished ring mold?" The buckle tutorial (I have
been trying to figure out what to call these things I keep writing, I
call them articles, but I really like tutorial) was something I had
put together a little while ago, but the ring mold was something I
was working on this week. I threw in the ring pictures to show the
height capacity of the big mold frame. I was also trying to make the
ring mold self-separating, which I accomplished, BUT I didn't get the
parting line where I wanted it, so I didn't show the results.
The attached picture is a set of home made RTV mold frames under our
bell jar, they don't make the size I needed so I made it myself and
made it as large as our equipment can handle.
