  1. Chuck, my first thought looking down the inside of the car was USAT, but don't think they made any 1:32?? Nice stuff for sure.
  2. For those of us, myself included who have never seen a full sized one:
  3. Sean, thank you. Here's just one of the things that make me scratch my head! Three increasing pressure, RPM's but the power output remains the same??? Fiddling with the pot on the pulse circuit will release the stall and allow power to increase which also starts the wheels. Can then adjust pressure/rpm to vary voltage and wheel speed. But starting again from dead stop, same results. Any thoughts???
  4. Jan, thank you. I don't know about WISE, but can tell you a whole lot of what doesn't work. These are just the gear/generator notes, another whole folder just for the boiler mods and other stuff. Not counting the countless videos on the lap top. Still havin' fun.
  5. Said I was stubborn. Was loosing as much as I was using, AIR. Very bright light and mag glass brought to light oblong holes holding shafts, fixed and realign gears for better tooth contact and less drag. Found an adjustable pulse wave circuit that didn't use a lot of V. Lastly a different generator that produces more V at less RPM. Still a ways to go to get what I want.
  6. Jan, glad the little girl is doing better, getting the best of care I'm sure. Nasty looking insect, will attempt to look it up. Stay Well Chuck, got some eye, had to play it slow to see it.
  7. Jan, a beautiful model, and looks like it runs well. Speaking of beautiful:::: Moritz doesn't have a care in the world. We wish you the best.
  8. Jerry, beautiful train, and really puts out the smoke.
  9. Chuck, thank you for the encouragement, more testing today. Stay Well
  10. Sean, thank you for the encouragement. Haven't put it up, but not devoting a lot of time to it, right now. The weather eased up some so several small not involved projects will be underway on the deck and fresh air. Stay Well and keep STEAMING.
  11. Chuck, is a nice car, do like the roller pick ups, wonder if Bachmann has any intention of using them on all their stuff moving forward??
  12. Jan, thank you, this is very relevant to what I am doing. Had this type of motor been in the model I would be much further along, and not have additional electronic board to deal with. I unfortunately am working with the motors the manufacturers provided, brushed and can I say not of the best quality. Any further information you have or can direct me to is greatly appreciated. Bug sends his best to Max and Moritz
  13. Pulse Wave appears to address cogging, which allows the truck motor to start at 2V and smoother than direct DC from the generators which started with a surge. Stumbled on a replacement circuit for a Childs ride in/on battery powered toy. Has a higher threshold and is also protected to re-set if over loaded. Couldn't possibly build it with the safety at twice the price, and no burned fingers.
  14. Stoker, never tried the screen inside the poker, but think by time flame reached the surface would be just one line blue flame again, instead of as many blue points as possible. Screen held In place by pulling one wire from side of the screen and using that around the screen & poker then just twisted.
  15. Jerry, thank you for the compliment, more like STUBBORN man. Chuck, you pegged it: What is cogging torque? "Cogging torque is the torque needed to overcome the opposing torque created by the magnetic attractive force between magnets on the rotor and the iron teeth of the stator. There are multiple rotor positions within a revolution where the cogging torque is high. Cogging torque can be minimized by adjusting the pole and slot count of the motor, by skewing the magnets on the rotor, or by skewing the lamination stack. By design, slotless motors have zero cogging torque as they have no iron teeth in the stator". Since I don't have the ability to do any of the suggestions decided to try 'pulse wave' to kind of kick start it, and to my surprise it worked. Till I got carried away, wasn't watching meters and fried the test circuit. Parts in transit.
