Claying up parts is a long boring task. This is a long out of print engine that will probably never get kitted again, It's really cool too! This is an afternoons work. You might not think it looks like much, but it does take some time. Parts are carefully set on pyramid shapes of clay. If you think about how a snow plow goes through deep snow and slices though it to move it away, the principle is the same. Well, maybe the analogy is not a good one. I think what I do makes a big difference in the mold being able to successfully make good parts. The area next to the part that is raised will be a place that I will make venting holes. Parting lines are important to this success also. You should take great care in deciding where the parting line should be in your new mold. Sometimes it just makes good sense to do as the original part was made and just snug some clay up to a line on your original part. Take your time and be patient. In any aspect of resin casting you will need lots of patience. The clay I use is KLEAN KLAY. The best deal for this clay is by ordering it from Alumilite, a company that you can mail order resin and silicone from. You might also find some of their product line in craft stores. The black marks on the parts are to keep track of my parts. I am working on two sets of parts. I have a set loaned to me from a mint kit and a set from a nice example that I took apart very easily. I also have some mint parts that I removed from sprues to do this project. In one photo is our newly mastered 1967 Eleanor Mustang convertible body. Originally mastered by Raoul Coulombe. Raoul envisioned a "what if" car and the Fastback version was created for the Nicholis Cage version of the movie "Gone In Sixty Seconds". Rocky picked it up and added the trunk lines and worked the inner door panels. Back to the clay. I like to put pieces of it in the microwave on a reheat setting. I also set it out in the hot Arizona sun and it gets sweating sticky hot. The clay being sticky is important to me as it will get a good grip on the really small parts as you will see this is important.
