I too have the same problem, no time to spare. Most of my time is spent working, usually 16 hours a day 7 days a week, sometimes 20 hours. Would love to be able to help in keeping track, but just do not have the time to remember my name half the time, let alone keep up to date on the TDR. Not looking to steal anyone's design/idea just thought that I could throw together the tooling and program to run off a few on the CNC, in my spare time, usually the time others spend sleeping.
