Thanx for all the support guys, much appreciated.
I have pretty much come to the conclusion, that I will be keeping them. Until I cut them up that is.
I know it seems petty, but for the strife and grief this ass has put me through over the past couple years and the fact that I likely won't see the money he already owes me, it seems quite fair. Not to mention that slurs the man has thrown around about me and some of my associates.
I have asked a couple guys in the industry, who have told me that I erred when I took money from him for the jigs. They stated I could just hand over the jigs, chaulk it up as a learning experience and move on, but I'm to much the Bear to do that. When they build jigs for their convenience, it is out of their pocket if they were not part of the contract. In this case, they say I should refund his money, but I have no legal obligation to hand over what is my design and my labour, lest he pay me for it. I highly doubt that will happen, so I guess he's SOL.
I won't put myself in this position again, I can garauntee that.
