I first presented a Scratchbuilding in Styrene clinic at a HUB Division (Boston MA area) convention in 2001. I've done it several more times, most recently for the Northeastern Region NERx on-line event in March, 2023. They saved it on YouTube, but the indexing of that event on the NERx site is bollixed. I hope this link gets you about 50 minutes of show & tell, including a couple of models that have threads on Modelers Forum.

If it doesn't, I was about 2:47 to 3:32 on March 22. Search around through archived NERx presentations here:

I've volunteered to fix the indexing, but to accept the help they have to give me access.
