rbrown7713 Posted August 13, 2019 Share Posted August 13, 2019 Here is what I came up to actuate a bell for a g gauge locomotive. I will have to do some more engineering, but this is a conceptual test and it works. Bob. Quote Link to comment Share on other sites More sharing options...

rbrown7713 Posted August 13, 2019 Author Share Posted August 13, 2019 Yes, I tried to edit it and it took too long, so you can watch it now, it's OK. Bob. Quote Link to comment Share on other sites More sharing options...
Screwy Nick Posted August 13, 2019 Share Posted August 13, 2019 Bob, sounds like you have a small motor with an eccentric to operate the bell. If I may suggest a 360' servo, 6VDC, will run at a constant slow speed and not make any sound. Heres a pic of the HS325HB servo that I have operating a pump to feed the boiler on my Mason. EDIT: just found FiTEC FS90R will also do it. Quote Link to comment Share on other sites More sharing options...
rbrown7713 Posted August 14, 2019 Author Share Posted August 14, 2019 Yes, I am using the same idea, except I won't have to convert rotary motion into reciprocating motion because I am using a magnet rotating on the servo crank and also a magnet in the bell. I won't have much room, so I will use a micro servo, an HS-81 servo, converted to 360 degree rotation, which I just did. I still have some work to do, but I think it will work just fine, if I can find the room for it. The example in the video was actuated with a magnet moved with my hand drill. The final concept will be a 360 degree servo. I don't know yet, how to hook it up to the DCS, I will need about 6 volts. I did order a controller that I can punch a button and it will actuate it, but I would rather use the DCS, but I don't know how to do it. Anyone know? Bob.

Screwy Nick Posted August 14, 2019 Share Posted August 14, 2019 Bob, with magnet activation you have to space it just right, you are the one to do it. Keep us informed. LiG Quote Link to comment Share on other sites More sharing options...
rbrown7713 Posted August 14, 2019 Author Share Posted August 14, 2019 Does anyone know the voltages supplied to the Challenger smoke unit? It has two supplies of voltage, one to the element and one to the fan, with a variable resistor that I can change in the front of the engine. I am thinking about using the smoke on and off to control the movement of the bell and I am not using smoke because my loco is battery powered. Any info. would be appreciated. Bob.

rbrown7713 Posted August 14, 2019 Author Share Posted August 14, 2019 I talked to Ray and he told me that I should use the fan portion of the smoke unit and the voltage is 5vdc and that is perfect for my servo. I will be able to control it, on and off by the smoke control button. I am not using the smoke, so no problem. Bob. Quote Link to comment Share on other sites More sharing options...
rbrown7713 Posted August 14, 2019 Author Share Posted August 14, 2019 I found a more compact geared motor. I might use either one, haven't decided as I need more testing. Room is not a problem now as I have removed the smoke generator. Bob. Quote Link to comment Share on other sites More sharing options...
rbrown7713 Posted August 15, 2019 Author Share Posted August 15, 2019 Here is test 2 using the small gearbox to move the bell. The next thing will be to mount the motor and use the dcs controls to turn it on and off. Sorry about the video. Bob. Quote Link to comment Share on other sites More sharing options...
Screwy Nick Posted August 15, 2019 Share Posted August 15, 2019 Bob, video is great. You did it, and that's action that is not seen on many locomotives of G scale. (oops there I go again). G Gauge, but yours is the first I've seen that is magnet actuated. LiG Quote Link to comment Share on other sites More sharing options...
Sean Posted August 15, 2019 Share Posted August 15, 2019 Ok looks great..so when the unit is moving I would belive you will have a bell sound .. How will you do that ? Quote Link to comment Share on other sites More sharing options...
rbrown7713 Posted August 15, 2019 Author Share Posted August 15, 2019 I will have to use two buttons, one for the bell sound and one for the smoke, which will be the actuator, unless someone can tell me how to integrate the two.

rbrown7713 Posted August 15, 2019 Author Share Posted August 15, 2019 Here is the finished bell mounted, works, but not in synch. I would have to program a slower bell to be in synch. Good enough for me. Bob. Quote Link to comment Share on other sites More sharing options...
