While it sucks not to know everything about how your cue is being built but its totally fine with me from the standpoint of business and making money. If I fully disclosed who made the cues or where I made the products then that would be spilling the beans on industry secrets and trade secrets.
Like any products being sold today you are not going to get full disclosure on how they make or produce it. It's what separates them from the competitors. Now if you want to buy my future line of cues and take it apart and saw it apart to see how it's constructed than by all means.
I love cues and wish I had the time to learn how to make it but I have a full time job and I want to bring the consumer an affordable custom cue. Perhaps 5 templates where they can customize from. From veneers to how many pieces of inlay. 5, 10, 15.....
As for me holding a sandpaper, it's marketing, I would rather start with myself before I hire models to dress up and pose with the products. T-shirt companies usually have the founder modeling the shirts before they hire models.
I can easily acquire ready to be finished parts and put it together, hence, I'm a cue builder not a cue maker. I can build it with the right right parts since I do have equipment at home to do such.
