From my experience; I have built rods with NO specialty tools what-so-ever. They turned out OK, but not as "sleek" as I would have liked. I did the 15 minute rotation for the epoxy cure, but the rod dryer is so much easier with nicer results. As for a thread tensioner, I simply use a book with the thread going through a few pages next to the book spine. If you are budgeting, I suggest the rod dryer above the rest.
