Been there, done that. Jigs do show up from time to time on Ebay. The Ebay jigs are mostly from an outfit called Whisky River and the top comes compleatly off on them. I actualy like the way they are built a LOT better than the common jig. It's a super nice feature since you can make toneboard slightly oversized (or use a std 5/8 dowle or rod of acrylic for a two piece) and it will fit the jig. Get a loose bore in the barrel and it's no problem to build an ovesized toneboard for it. Now, having said that I bought a used Whisky River jig and was never able to get the sound I wanted (or any acceptable sound :-[) from it. I am the third owner so I suspect its just a bad design or has been modified by a previous owner. On the other hand, I put some toneboards in it the other day to see how it matched up to some known boards and I was quite surprised to see it was a near perfect match to a Extreamly Well Known Customn Call Makers call. I purchased a pair of calls from this maker two years ago and did my homework. Now I may go back and see if I can get a working toneboard from that jig. I have learned a heck of a lot about toneboards since I gave up on that one and it may also just have been just my lack of expereance. I have a 2g jig I got from a fellow poster. I also got with it, a working (and I mean a ROCKING!) toneboard made from that jig as well. I think knowing that jig could absolutly produce that sound made all the difference in the world to me. My first toneboard off that jig was a keeper! Now I have a very consistant approach to how I modify each toneboard I cut from it and I know what my own jig would look like if I ever have the $ to have my own jig made. I will say this, when I do have a jig made, It will be made so the top comes off ! So what is my point here ? Just that there are other jigs out there, but it's buyer beware! and there is more than one design and design can afffect functionality. I know this didn't help one bit, but it's my input regardless. Ultimatly you want a private jig, and any step in that direction is a good step forward.
