I think you are right. Eventually, I end up changing all my stuff to DCC and adding capability. However, when I get to the point where my frustration is too high, then it is time to run some trains. I sit back, watch the train go around the room, watch TV and then sometimes, I get working again that same night. But, tonight is definitely a no go.
I was cutting my brass tubing to adapt the flywheel to the motor. Normally, I have no issues. Today, nothing but issues as I could not keep the blade in the same groove and was just making what looked like spirals. I use the razor blade method and go back and forth until it finally cuts through.
I don't know of any other way to cut 1.5mm brass tube. It needs to be precise enough to allow the flywheel to slide on. A little resistance is good, but not too much or I risk damaging the tube. The inside diameter is something I can recover from with a .98mm drill bit.
Tomorrow is another day...
