You know this is not my first rodeo, I had been building cues for more then 30 years, I know exactly what happened.
You had buyers remorse, and you figured that if you said that the cue was not as described, eBay would give you your money back. So what you did was sand the shaft joint down so it would show a mismatch, and then you gripped the wrap with both hands and twisted back and forth, to stretch the leather so it would look like it was loose.
Here is a lesson for you. If you had just messaged me indicating that you didn't like the cue, and not put in a false claim on eBay and calling the cue junk, I would have given you your money back or exchanged the cue, but you choose to commit a fraud, so live with it.
As far as posting on Facebook or other sites, have at it. You are just going to make yourself look like the dickhead you are, because you will run into a lot of my customers that are happy with their cues. Besides that, I retired from making cues about 2 months ago, and am just selling off my inventory, which amounts to about 9 or 10 cues left, and I really don't care if I sell them or not, so you cant hurt me.
