This tender had been modified, with the pickup guide tubes shortened and the crimped ends of the plungers cut off. As a result , the plungers although contacting the centre rail, were under greater pressure. As it is easier to lengthen a compression spring than to permanently compress it, I chose brush springs which naturally are shorter, and gradually lengthened them. The result was satisfactory.

Hi I run 6 Hornby engines with tender pick up via plunger pickups ,4 F8 two i converted from 2 rail with 3rail tenders . I made all the connections apart from 1 castle solid wiring doing away with the poor plug in tender connector. The plunger springs seem to be the same as the ones used to put pressure on brushes as used in the old hornby upright motors so quite light pressure . The insulating around the plunger could break down and cause shorting . Good point using stranded wiring inside the tender .

I had the opposite problem with a recently acquired 3 rail non- Ringfield Castle. The plunger springs were quite strong and retarded the forward movement of the tender considerably. I replaced the original springs with a pair of slightly elongated brush springs for the vertical motor. Much better!

Hi Dusty. first impressions are that the Meccano repair in 1961 was fairly expensive, virtually half the cost of the the loco new. However the front bogie has a new set of wheels and the motor wire has been replaced.

the plungers in the tender look good and apart from cleaning, leave well alone. Like the mechanism in the TPO van, works best when dry. Meccano crimped the plunger shaft and rivetted the tags so disassembly is impossible without causing major damage. I believe your issue here is that the tension of the two brush spring arms is excessive.
@dustyshelfcollectables Жыл бұрын
@@premikyam2726 That interesting, so let me just clarify reduce the tension in the spring and less force pushing the brush against the armature?
@premikyam2726 Жыл бұрын
@@dustyshelfcollectables Yes. a case of less is more, i would say that the arms of the brush spring without tension should be adjusted to approx 20'. Also worth checking the clip that plugs into the tender. definitely clean the clip and the socket before any major plunger surgery.

I kept the body of my 2-rail Bristol Castle for half a century. Two years ago I needed a large GW firebox top for a scratch build...so out came the saw. The set in the 1950s had two rather short, enamelled tinplate coaches with nice interiors.

I'm a new subscriber and enjoying your channel, I had a Hornby Dublo 3 rail train set when I was young, a long time ago. I had a Dutchess of Montrose that exhibited the same symptoms as your Castle. I tried everything like the collectors all the wiring cleaned it all up and said to my dad, I'm stuck on this loco. He was a telecoms engineer and taught me a few tricks and taught me how to use a multimeter. The one supplied with Mr Dodd's magnetiser will do. I think you may have a 'dry' solder joint on your armature where it solders onto your commutator, which can give you intermittent running. If you look carefully those coils are very thin and can break so total care. There are three solder points on a three-pole motor and the coil of one coil goes to the next commutator coils or adjoining coils each solder point has two coil ends soldered together and to the commutator segment at this point its worth making sure the gap between the segments are clean and use a wooden cocktail stick, gently. With the armature removed measure the dc resistance between the two adjoining commutators all around so you should have three readings and make a note and compare the values, they will not be exactly the same but quite close. I would reflow the solder joints regardless and if they look dull I would reflow them anyway. Use a little flux or fresh solder on the tip of your soldering iron and soften the solder and remove it quickly when it appears shiny. Don't dwell too long with the iron and measure again. There are many reasons why solder joints fail and that includes heat expansion and vibration that can occur where the tiny coil is not conducting electricity properly and arcing occurs making the flow of electricity through the joint behave erratically or intermittently making and breaking current flow. I hope this helps! Ian

Thank Ian, that's interesting, I will take a look, I think in this particular loco it was the plungers that needed resetting, but I do have another that is doing a similar thing so I will pay attention to the armature. Thank you for watching and for the advice. Matt

The only experience I have with plungers is on a 2 rail Airfix 14XX. It's possible the plungers are sticking. I used contact cleaner and a light oiling. I know it's a different loco but it worked for me. The cost of that repair alone would have been a fortune for some. I hope you get it sorted as its a lovely locomotive. Regards Paul.

Hi Matt, I've solved this problem on my 3rail caslte by soldering a soft muti strand wire to the top of the plunger shaft , joining each of the plungers and then on the tender connection. You might find that you have to file the top of the shaft to obtain a good soldered connection. Leave the original wire in place.

The way I cure this problem is to file the lower half of each plunger shaft crimped section away with a needle file. This allows the plungers to descend a little further resulting in compensation for the slightly worn plunger shoes.

You can also solder a cap over the top of the plunger with a thin layer solder will add a little depth and will keep pressure on the pickups, and the solder is softer than the rails so no damage to the rails either

Hi. If the sticking only happens with that particular loco, either try replacing the plungers by making your own or, if the track has indentations, simply replace the sections that have them. 👍 Paul.

Just had a look a my three rail castle tender , the plungers seem quite softly sprung and when not the track they come down below the tender wheels so when the tender is on the track the plungers will under tension which means if the tender goes over some uneven track the plungers should drop down to follow the contours of the track . It might be worth looking at plungers to see if they are little too stiff and not moving up and down freely. Putting a little PECO power lube on the moving parts of the plungers could help free them up and improve conductivity, but only use a little as it can go everywhere.

Hi GC. Better still, use WD40 Contact Cleaner spray (NOT plain WD40) as it can splatter without harming any part of the loco (comes with a narrow plastic tube for directing the spray). OOBill on KZbin uses it all the time and I swear by it as, after a short period of time, it frees up moving parts of a loco that are sticking. 👍 Paul.
