Getting all this stuff together in your shop is probably the biggest challenge a new rod maker faces. Sure, many of these tools you can make yourself but you better have a lot of time on your hands to make them. What you might save in money by making them will be more than lost in the time it takes to make these tools. This is something to consider especially for someone looking to make rods as a hobby.
I would also urge you to consider finding a dealer that will stand behind their products & provide you with good service even after you've bought from them. It does little good to save a few bucks on an expensive piece of equipment or rod component, only to hear their voice mail every time you call should a problem arise. In my opinion your best bet is to buy from someone who actually uses the tools & components they sell.
While I don't offer tools or rod components, you might want to look for a competent rod maker who does. This is especially true if you're just starting out in rod making. Not only can they make sure that you're getting the proper equipment, they can also answer your questions about it, too. I was fortunate to have many experienced rod makers help me when I was starting out & I'm grateful to them all. One of the many rod makers who have helped me, for example, are the folks at J.D.Wagner Rodmakers. They were, & still are, especially helpful to me when I need specific rod components or a certain tool, & if I ever run into a problem I know that I can ask them for honest advice. I suggest every budding rod maker find an experienced one for guidance. Most rod makers are willing to help answer a beginner's questions, myself included.
