I'm pretty sure I recall hearing that if you cut features that are too thin in Delerin, it gets too hot and catches fire easily. I don't think you were allowed to cut it at the maker space I was at. But it's been like 7 years so I could be fuzzy on that.
That's one of the reasons I started with this article in the first place: there is so much knowledge about all of this stuff floating around but it is very fragmented. I wanted to have a single notebook for myself to keep track of what I've figured out, what works and what does not and then it seemed a natural to share it with others. Over time I intend to keep fleshing it out.
