    Very interesting and informative. Because I bought the Airfix class 31 like new from an over 80 years old store owner in Dorset for only 20 GBP plus shipment to Germany. A really wonderful diesel loco for their age.

    Well I’ve had one since 1977 (blue type) it’s been loud for as long as I remember so after a little oiling and cleaning up she’s running sweeter than in years. Bogie was fragile though cracked it slightly but nothing major . Cheers for the good video and I still love the old girl.👍🏻

    Great little models these 31’s, though that can be said for the whole Airfix range in my opinion; I love their whole offering.
    I got a 31 loose, in blue, as a non runner for a tenner a couple of months ago, but lo and behold the motor runs sweet as a nut and the non running only comes from some loose wires. She’ll likely end up detailed a bit and maybe even painted into coal sector livery, I’d like to double head a pair one day.
    This is an excellent guide, quite like the rest of your productions. The info regarding the screw on the worm gear is especially helpful. Cheers.

    Hi Dave. Great video about a great manufacturer. These 31s are v powerful and being 5 pole they can be very smooth too. I will say yours still rattle along somewhat...with some care they can be much smoother than that...although if you have a pwm type controller like many recent hornby ones then that can cause the buzz. If you look on my channel I have airfix locos pulling over 40 wagons with ease!

      @gs425 5 років тому +1

      @@ModelRailwaysUnlimited hmmmm. Well I would have suggested your bearings may be loose but you said they were epoxyed in. The motor shaft does benefit from a medium to thick oil. I have noticed rattles from body shell or glazing in diesels before. Maybe try run them without bodies and see what they are like.
      Btw it's interesting that you say you have remagnetised some of your motors before. I have done some work on this myself and 99% of Triang motors were made of alnico 2 which has a high coercivity, so should be fine. I believe airfix motors are too. In fact the only magnets I know for sure that can suffer loss of magnet strength are in hornby dublo locos. There is a LOT of subjectivity on forums about this subject, but little real knowledge it seems. Any comments and especially measured improvements welcome. I have just ensure my notifications are on properly for your channel, a good watch. And especially refreshing to see positive mention and service tips for this sort of older loco. Cheers. Gary

      Hi of course you can ask. The cap is a legal requirement to prevent radio and TV interference, however it also has some helpful effects on limiting brush erosion and acts as a block against any AC element present such as HF track cleaners. The value is usually 104 or 0.1 uF Chose one that is at least able to cope with 50v

    You need to show how to get motor out of bogie and stress not to touch fitting on top for the connectors that hold the brushes in place which I note you avoid doing yourself, as they’re next to impossible to refit once the brushes have fallen out. My opinion for what it’s worth is that these Airfix 31s are excellent but over engineered locos and best left alone unless they’re non runners. Unlike Hornby and Lima not an easy tinker for the amateur. The screw causing grinding noise sounds like a top tip only screw doesn’t seem too long on mine so maybe a problem confined yo the engine in the video.

    • @ModelRailwaysUnlimited
      @ModelRailwaysUnlimited  5 років тому

      Hi and thanks, regarding the brush retaining spring and wire connectors, these seemed normal to me, I did strip it back completely but never thought to share that. Spring is held by the screw, tension can be adjusted by slightly bending the spring wire to get a more even but reduced brush pressure. Brushes are lifted from the underside back into place and held by the spring. Hope this helps?

    In regards to the problems you had with your Hornby S15 a year or so back. Not sure if anyone has enlightened you but you DO have a PROBLEM, but it was NOT the Hornby S15 that was the cause ! You were clearly using an old H&M Half Wave controller, an early and problematic type of electronic controller. The normal basic H&M range were fine. But when H&M tried to get smart an provide a more responsive controller to cope with the Stone Age motors in Tri-ang & Hornby toy trains of the day. It all went pear shaped because Club modellers were already starting to use better quality Japanese can type motors in their lovely kit built models, which are effectively the same type as Hornby now currently use !!!!
    The H&M Half Wave type controller you were using, as seen in your earlier videos, rapidly got a very bad reputation, for causing "death by strangulation" of better quality Japanese can motors, and later it was also blamed for "Instant suicide" of expensive Coreless motors such as Portescap & Fulhaber. Get rid of your H&M controller and you won't have similar problems with your new Hornby locos.
    The H&M Half Wave controller whether in "Half" or supposed "Full" Wave setting actually chops 16v AC in half (halves the wave) to provide Half Wave AC, NOT pure 12v DC. Hence your S15 was demonstrating all the classic symptoms of "death by strangulation" of the motor, i.e a slow burn out as indicated by your Ammetres erratic milliamp readings.
    I have four S15's working on my large 87ft x 25ft BASINGSTOKE exhibition layout. These locos have to haul full scale length trains even up 1 in 100 gradients. Apart from adding extra weight inside all of them to ensure they can cope with their trains I've had no problems with these or any other Hornby or other manufacturers motors, including Portescap. Although Hornby motors may not be the very best available, they are good. I use normal 12v DC Gaugemaster panel mount controllers on my layout.
    I can recommend normal 12v DC Gaugemaster Controllers with the cream facias. Either cased versions including a built in transformer, or the panel mounting versions. Just avoid the little Gaugemaster hand-held version with a BLACK facia, which has a bad reputation for burn outs, because its a "feedback" type.
    One other problem now facing people who do NOT use DCC is the increasing amount of expensive electrical parts installed in such things as Hornby Pullmans, so the vehicle can detect whether you use 12v DC or 16v AC (DCC). Capacitors are now often included, and this dramatically raises the amperage demand of such vehicles, to dangerous levels. A Bulleid Pacific with 12 x Pullmans on 12v DC now wants to draw 5 amps, which cuts out my controllers within a few seconds. Removing the capacitors and all the other electrical goods, and rewiring the LED tablelamps, reduced the draw to a manageable 2.4 amps !!! I've also had to rebuild Dapol locos and strip out much of the superfluous electronics to reduce their amperage demand, before something catches fire !!!

    • @ModelRailwaysUnlimited
      @ModelRailwaysUnlimited  4 роки тому

      Hi and thanks for the in depth reply, you are preaching to the converted however. The controller is in fact an H&M Safety Minor and its full wave output is pure variable DC. It also passes through a filter circuit before it reaches the track which includes an inductor and 100uF non polarized capacitor that adds smoothing to the output and makes the test rig suitable for coreless motors. The wave form can be seen in one of my controller videos and it is on par with the Gaugemasters you refer to, in fact with the mentioned circuit it is more smooth and more kind, 33uF added to the output of the GMs will remove the buzz on start up and crawl you might have noticed but will not affect slow speed performance. Many thanks for your information, Hornby do not seem to have any clue as attested to by that really dreadful silver train set controller they persist with a ignominious device indeed! You may find this page interesting www.rohm.com/electronics-basics/ac-dc/rectification As you see full wave and half wave is actually 50hz or 100hz
