In that article Terry Metcalfe described how he cast parts by melting beads of a thermoplastic called “Makit and Bakit” beads in RTV molds using an ordinary kitchen oven. I decided that this process was definitely NOT going to work for me.

  It has been nearly 30 years since my "Hot Glue Casting" technique was published in the "Narrow Gauge & Short Line Gazette" magazine. Although this innovative process hasn't changed much over time, the availability and cost of Room Temperature Vulcanizing Silicone (RTV) as well as weathering and finishes has had some significant innovations. Now is as good a time as any to refresh this article with additional information and lots more color photos than was in the original publication.                              (16pgs color & B/W) Read More ...
