In the middle of winter in the midwest, you really need something to do. I build rods for myself, friends and family. I do not solicit any outside business. Yet. I'm retiring at the end of this year; leaving my full-time teaching job, and keeping, for now, my part-time consulting gig.
I'll have a lot more time next year to spend doing something. I'm in the process of making mistakes, learning new procedures, and generally getting better at this craft. Am I a "professional" at this point in time? No, I most certainly am not. But, I'm getting better. Every new project is an adventure, and a learning process. My friends and family like the rods I've built, and the ones I've built for myself fish well. The fit and finish is not up to professional standards, but will be soon. I haven't used any high end blanks; more mid-level stuff so far. I have some high end blanks, still in the shipping tubes, waiting until I think I can do them justice.
Some time in the future I will likely hang out my shingle, and start looking for customers. I have several regular customers for whom I service and tune reels. I will be expanding that next year as well. Adding the rod business should keep me well occupied. I won't make a living at it, but I don't need to make a living at it.
I've seen too many guys retire, plant their butts in a recliner, and die soon thereafter. I do not intend to do that.
