PIG CASTER Part 5
Work continues on the mold conveyor belt section of my pig casting machine. It has been extremely tedious work, building each idler wheel assembly and each pig mold. I also have been having problems with the styrene warping. Most of the basic framework was relatively flat after being built, however, after I glued on the separately assembled pig mold belt, the entire assembly curved badly - to the point I am worried about getting it all flat ultimately when I assemble the return belt section to the upper belt section. If anyone has experienced this and dealt with it successfully I would like to hear all suggestions. I might be hoping for too much that the assembly will square itself upon final glue up. The picture shows the upper belt assembly - rear on an angle, and the return belt assembly, flat and weighted down by glue bottles and other things. The pig molds are made from 1/8" Plastruct deep channels with .030x.100 sides - I will go back later and add small round punch outs at the joint between every two molds.
