    I can still see HT1's pics there by clicking/tapping on the "please upgrade your account" thumbnail, it's annoying to ha e to do that, but the pictures are not completely gone...

    Please do not send this piece out. I'll miss out on the "how to" aspect of it altogether. I have some upcoming plans that will require the precision of creating some complex shapes with the aid of CNC. AND I'll need to turn those into cast bronze. I could just as easily send out some of my junk and pay the man, but then whats the point?

    Typhoon, check this out. Right up your alley.

    Nothing sensational here, just a try. I made a plaster cast to see how it would look as "positive" model.



    I knew the edges of the cast would be bad because the grooves in the plywood aren't clean enough. A v carved bit may not be the best tool , I'll switch to a round nose bit. I just wanted get a general impression and overall it worked.

    I downsized the cross to 14cm (5.5") and reduced the depth cut to 1mm (40 thousandths). This time I machined a HDPE cutting board. Then I cast the model in plaster (left) and in polyester resin (right). The plaster cast is not good but the other one went perfectly. You can see the discoloration in the middle where the texture is rougher and the little scratches left by the knives. I was a little in a hurry and managed to break the cast, my bad, had to glue it back together.

    I had not played with polyester resin for years but it's coming back. We're close to the final product.

    I think I will cast one in aluminum first, then maybe one in brass.

    I glued the back and sprayed a light coat of paint.
