Ukswrath I am almost done following along with you guide for my TK. It is beyond useful. However one thing I keep having problems with is return edge size. I know they are not required, but I want to keep them where comfortable.
It would be extremely useful if sometime you could add a separate section (or maybe in fitment alterations) for all of your return edge sizes in mm. I am a similar size as you and it would save me, and probably others much guess work. I am having a hard time telling in the pics.
