OK, really hate to ask this one, as it may show my ignorance, but why would there be 4 chuff's per wheel rotation.  

Seems to me one chuff would come from moving the drive piston one full stroke which would turn the wheel 180 degrees, and the second from the drive piston moving in the opposite direction a full stroke, turning the drive wheel the other 180 degrees.

If there were 4 chuff's per rotation, the first stroke would only turn the drive wheel 90 degrees and the second would just pull the drive wheel back to where it was before.

I could maybe follow it if there were two "double Chuff's" in rapid succession, on for each piston on the opposite sides of the engine, but would a "doule Chuff" sound that much like two seperate chuffs?

Think I really need help on this one.

            Now for the second lesson! Why do three cylinder locos have 6 chuffs per wheel rotation? How many chuffs per wheel rotation do 4 cylinder locos have? Three and four cylinder locos are common in Europe........Cookie

Gidday again Len and Johnathon
                                                     When I checked the motor it was loose so I packed a piece of styrene between the frame and the motor which has quietened it down. Thanks once again for the suggestions......Cookie

Thanks Len and Johnathon, I will check these suggestions and let you know what happens. These will be easy solutions if they work. Off to the shed to see if I can quieten the growling beast!! ..... Cookie

            I have a Spectrum light mountain that growls in forward and reverse. I have taken the loco apart and greased the worm gear and oiled the motor bearings lightly. All other oiling points have been oiled as well. This has not stopped the growling. I have three other light mountains and they run perfectly. What could I be missing here, has anyone else had this problem and solved it?.....Cookie

            To thin Floquil I have always used 3M car care General Purpose Thinner. Automotive and Industrial thinner. This also cleans the airbrush. I have been using this product for many years and have never had a problem with it. I do not know if you can buy it in the USA.

            If your control system allows it, you can program the CV,s on the main whilst the loco is running. This does not take long at all......Cookie

               Do Bachmann decoders have BEMF??  I think the Bachmann Tsunami sound decoders have BEMF. As stated elsewhere, we need to know what decoder is installed in loco.....Cookie

                I had great success quieting-down my older Athearn locos by gluing, using Silastic, very thin pieces of lead to the inside of the body wherever I could fit them. Don't ask me why or how it worked, but it did the job!...Cookie

Actually I do have an nmra gauge which measures coupler height.  Jonathan. was right the coupler was hanging too low. I corrected this by filing the coupler box a bit. problem solved.

Gidday
                           to raise the height of the coupler I use the Kadee undershank coupler and to lower the height I use the overshank coupler

                  Very fine job!! Well done.

                      Yep, that be them. Thanks for the reply.

           I have been given a Spectrum medium length vanderbilt tender and have noticed a set of connector wires loose in the box. What are these wires for? I already bought a Vandy tender and connected it to a Consolidation, but I did not notice extra connector wires with this tender. The connector wires from the consolidation just plugged straight into the tender. I have a TCS M1 decoder installed and the capacitors disconnected and the loco runs smoothly and oh so slowly. Beautifull!!!

Gidday
           Thanks for the info, I can do that no worries. Easier than I thought. Once again, thank you.....Cookie

Gidday
            Can someone tell me which tenders will interchange with which locos in the Spectrum line of steam locos. I am wanting to attach a Medium Vanderbilt with a light 4-8-2 and the same tender with a 2-8-0. If I can, I wish to avoid hard-wiring the tenders to the locos. I am just lazy I guess. I can hard wire if needs be, but if the tenders will just plug-in it will be much easier. Thanks for your time and effort....Cookie

How many of those old enough to remember "77" still need a comb?
