Anybody know where I could download a template/protractor for this arm?

You're referring to vinylengine. Yeah, I had found that. Problem is that it's not to scale - you can't just print & use. But I'll give it another look.

go to this site and click on the left bar "translate to english"...if your Japanese is not brushed-up yet!
It looks like there are simple, universal protractors I can use. Who knew? (Almost everybody, probably.)
