I've put a PDF file of the slides from my Advanced Mold Making and Resin Casting clinic this evening in my Dropbox. Here's the link to download:

It's a big file, 16Mb, and there are 200 slides on 100 pages. It will take longer to read than it will for me to present! (It's essentially a narrated slide show, most of which shows things step by step so it moves very quickly and, hopefully, smoothly.)
