To clarify: I was going on a trip for 3 months, leaving April 5. After talking on the phone, I made a decision to make part of the trip taking the Minisonic in person and expecting an estimate while I was present. I delayed my travels in Colorado to arrive in Barstow on the day Don was scheduled to return. But then he wasn't there and I had to leave it. From the beginning, since I had tested the hoppers, and one worked fine, #2 was intermittent as its wire was pressed or jiggled, and #3 did not work with the switch, but did if it was bypassed with a direct connection. All I had wanted was to have the wiring replaced. When I received a return call days later, I was told I needed new switches, etc. I said I would just like the wiring replaced and couldn't that alone be done. I was told no, all this other stuff was necessary if I wanted it working again. I reluctantly agreed, because otherwise I had brought it all this way for nothing. Then after more time delaying my itinerary by remaining in southern CA, I was told that sorry, but that didn't work, and it might be best to buy a new one, as now it would cost as much to replace more parts. I said, then just return it as I brought it in. But when I had thought that was going to be the case and went to pick it, is when I was shown that it was in the new, but non-workable state. The switch system was a different mechanism from the original, and I suppose that maybe the newer system wasn't powerful enough for the old coils, which all had very string power previously. It seems to me that if there was any uncertainty that the changes could have been made on one hopper, like the 3rd instead of doing all 3 and saying, that unfortunately there isn't enough power to move the load. I had hovered around southern CA for weeks waiting for the analysis, go ahead, work done and then expecting it undone and given a date and finding that I was given an ultimatum. I continued on the rest of my trip, through, CA, OR, WA, then east to WY, WI and returning at the end of June. I didn't even unload the box with the machine for several months later from the compartment under the false floor in my truck for months, as I adjusted to more pressing adjustments. Then I hoped that maybe it would work, but they would just vibrate weakly and not move the load. All I had wanted was to replace the original wiring, and was told that would not be done. I agreed to what I was told was necessary for functionality and got something back that had less than before. As I recently began again to work on other dormant lapidary equipment, I was reminded of this incident. I also have the large Vibrasonic tumbler, and accidentally broke the switch off. I got a duplicate switch at Grainger's and then found that I had to get new terminals as well and replace. Did so, put it back together and tried a test load and it moves as it should. I also rehabilitated my Frantom combo unit, a diamond band saw, a Lortone tumbler, and some other things. and am currently trying to get my Nelson 24" saw running again where the problem is again related to wiring, to the switch box and power button box, which is likewise a little complex to me, but bypassing the switch and connecting directly to the motor shows that the saw will run, The date is close the anniversary of my leaving on the trip, that brings it all back to me, and how I felt totally misled.
