Manny, I've built about 40 rods over the past 15 yrs or so. If you want to come by some time and see my set up let me know. I have some photos of most of the rods. I could give you some tips.
As far as making money selling rods, I would agree with the others. I've talked to a half dozen rodmakers that sell rods at fishing shows. Three said they were not happy about sales, and felt it was a mistake thinking they could make a buck doing it. They didn't seem happy. They had a nice quality product. Two enjoyed what they were doing. To them it was a hobby that they could do and they weren't too worried about profit margin. They just enjoyed showing their rods and talking with people who visited their booths. Selling a few rods was a bonus. They were having fun and also had a very nice product. One fellow said he was making a good profit on his rods, and was selling a lot of them. He was very enthusiastic and had amazing threadwork and designs on his rods. His rods were selling for hundreds of dollars per rod. He said he had quite a few famous people buying his rods. The people buying them were looking for something different. He was providing it. I don't know how long it took him to build up his clientele, but he said he had a nice waiting list. I think he is the exception.
