Newton made his own iron gall ink according to a recipe found in his notes [0]. By using the same recipe you can sort of feel a connection to him... Also, think about it when you hesitate to "reinvent the wheel" or "perform some work below my pay grade". The man actually fabricated his own ink for writing! If Sir Isaac himself could set aside time for this mundane part of his work, you certainly can. (Also, he polished his own lenses, an extremely arduous process; although there were many people in England at the time who were more skilled than him in glass polishing. He found that the very nature of polishing glass inspired him thoughts about the physics of light [1, chapter 1].)
