Help With Clay and Wood.... I have a couple projects I have been putting off for a while because I need advice before begining them. Firstly I have been wanting to make a puzzle box. The same sort of idea as the one in Hellraiser except that I will likely be using wood and mine wont contain a gateway to hell or anything like that. Not that fun I know but if you could get past that I would appreciate the help. I have one specific question. I want to make sure that the wood surfaces will slide across one another with minimal friction. More specifically I am concerned about two larger flat surface areas sliding across one another, not just joints where there is a minimal of surface contact. I was once told that a higher grade wood sealing wax may do the trick and that I could likely use it both for reducing the friction for the sliding parts and for putting a finish on the project as a whole. Does any one know anything about using a product like this and just how good it would be for this purpose? Maybe someone knows a better technique? Also I have had a hard time finding any sort of site that might help me with design concepts for the working mechanisms of the puzzle. If anyone has any idea where I might find such a site or reading material please let me know. Second, does anyone have any experience with using polymer clays like Sculpey and Fimo? Specifically what I want to do is create a skeletal structure using one or two colours of clay then emerse this structure in a translucent clay and further sculpt the translucent clay into a desired shape. I have two particular questions regarding this. 1) Does polymer clay tend to warp and crack due to variation in thickness like normal clay? And will different colour clays set and/or shrink at different rates? 2) In regards to the skeletal structure; it would seem that baking this first before adding the translucent exterior would go a long way in making sure the structure is not warped or mangled in the process of adding and sculpting the translucent outter portion of the sculpture. Is this feasible? That is, can the clay go through a second baking without adverse side effects? And will the fact that the inner structure is not shrinking and setting the same way that the outter portion is compromise the outter portion in any way such as cracking?
