Cutting Fiber board for molds
I got a large piece of 1" fiberboard to use for mold making. I'm finding it very difficult to get a clean edge on this material Is ther a secret I dont know? I have already fired the pieces before i try to carve them is this proper or should I try it the other way? Any help will be appreciated :

Try carving before you burn them out. From my experience, they are less fragile and less prone to crumbling before they are fired. Also, use a really sharp exacto blade.

I had the same problem. I am in the sewing business and we use a rotary knife alot. I used it on the fiber board and it worked outstanding. Here is a link:

I also received a hugh piece of board..never used it before. Would like to cut out a big ring (drop ring) to make a sink. Do I have to harden this and how do I go about it?

Re: fiber board
I simply cut it with a razor utility knife. It doesn't much matter what angle you cut to, square, beveled in or out. Prefire it and go. I generally use some dry powders on it to help seperate. I like alumina or plaster.doctac wrote:I also received a hugh piece of board..never used it before. Would like to cut out a big ring (drop ring) to make a sink.

I recommend prefiring the board up to the top process temp you plan to use it at.
