  1. The cab roof and bonnet are just resting in place. It has had the first test run on the layout. I was a bit worried about how it would handle switches and crossings as I made an error putting the wheels on. Instead of a 14.6mm back-to-back, it ended up with 15mm. It has all gone well though. Current weight 159g. The first test with a train on the hook was 10 of my Airfix minerals. These have a slab of lead in the floor, so it was quite a heavy train. It pulled the train from the fiddle yard to the scrapyard headshunt without a problem and then propelled it back. The return trip is on a slight rising gradient. I tried my Bachmann 03 as a comparison, on the same train. It pulled but with a couple of slight slips, but it could not propel the train back up the line and sat unable to move, with wheels spinning. The odd thing is that I added weight to the 03, which weighs 28g more than an out of the box one. The Drewry weighs 10g less than the 03. I still have to build and fit a radiator cowl before the bonnet can be fixed in place. I'm not 100% happy with the windows and may try to make another set. There were none in the kit and I am led to understand that these kits have never had windows. If it was an etched kit I would stick oversize pieces of clear packaging on the inside, but with the thick plastic walls of the cab, this will look naff. I have had to use a thick clear plastic and have had to cut and file each piece to size. It's all very hit and miss. The fact that the apertures taper in doesn't help either. Other small details that I will try to get in are the pipes from the engine to the radiator, and the locomotive brake air pump and intake filter.
  2. I seem to have dodged a bullet with that one. I took the cab off and had a look at the decoder but couldn't see anything obviously burnt. I tried it again and, again, smoke from the decoder. This time I was able to touch it and I found the heat was from the connections to the stay alive. These connections were soldered on by the supplier of the decoder. I swapped the decoder for a plain non-sound one and this time it started to run and stopped, with the controller flashing up a short circuit. The decoder was swapped for a DC blanking plug and I tried it on DC. It ran but there was arcing between one of the motor wires and the running plate. It appears that when I unsoldered the original wire that was on the motor to fit the new wire from the DCC harness,, the new one was just a few thou. nearer the running plate. I don't know why a short didn't show on the controller when the sound decooder was fitted but at least I know what went wrong now. It's all working again and the decoder didn't let its smoke out. It does all need re-installing but that's a job for another day now. I'm just happy that the decoder hasn't fried.
  3. It was all going too well. I got the decoder in, which was a faff as it had to be put in place and the cab then had to be screwed to the running plate. The speaker was then soldered to the speaker wires outside the cab. The stay alive went through the hole that I cut in the firewall. Engine sat, but not yet fixed, in place. Brass tube elbow and solid brass bar silencer fitted. To strengthen the joint where it meets the printed manifold I drilled the manifold for about 5mm. The tube has the same amount of rod sticking out from a soldered joint, which goes into the drilled hole. Joint fixed using superglue. The silencer has had a flat milled along the top due to the thickness of the plastic bonnet top. Bonnet in place, but not yet fixed. I fired up the sound, which all sounded good, but as soon as it started to move the sound ceased. It sped off and I had to grab it to prevent it from smashing into the rollers on the test track. Then all the smoke escaped from the decoder. As we all know, electronic devices run on smoke and once it gets out they stop working. At least it didn't do it when everything's finished because once the bonnet is glued down it will be very difficult to get at the speaker and stay alive.
  4. I've got Mike's 88DS in 7mm, but it was before N20 gearmotors were "discovered" and I built it with all the panels in place. I've wondered about doing the same but I don't think I could get the panels off now. It would be great to do an engine in 7mm as you can even put all the injector pipes on. Here's a 3VRO for a Wrightlines 33/40HP narrow gauge Ruston that I made from plastic and wire. It's a bit crude, but it was about 20 years ago. Back to the RSH/Drewry and the DCC kit arrived, this morning. I can't simply fit it as various things have to be done and in place first. The decoder is a Zimo MX649N, which is the version with 6 pins that plug into a socket. The plug is something that I cut off some RTR loco or other. The idea is that the decoder will sit between the motor and the firewall of the cab and be under the control desk. The only visible parts of the set up should be the wires, which I will paint black. A driver figure should camouflage the motor somewhat. The speaker was going to be below the fuel tank but the engine is longer than I thought and won't allow this. Instead the speaker will occupy the fuel tank space, alongside the stay alive. The sump and lower part of the fluid flywheel casing will all have to be sanded off for the engine to sit at the correct height. This will be the normal viewing side of the loco on the layout, so I'm not even going to attempt to add injector pipes that are all on the other side! The exhaust connects to the manifold at the rear and curves back to a silencer above the engine. I'll probably try and make the cables to the starter motors and maybe a fuel line to the filters.
  5. This 165HP diesel arrived in 1975, from a shipyard in the North East of England. It was only recorded working a couple of times, before being shunted into the scrap line. A shortage of motive power at Shelby Group's subsidiary, White Peak Limestone & Tarmacadam Ltd. saw it taken into the Watery Lane workshop for servicing and an overhaul of the brakes. IRS records show it as being seen on the 10th of August 1976 on the back of a Shelby Haulage low-loader at Stafford Services on the M6. A 1979 visit to WP, by a group of IRS members found it in the loco shed under repair.
  6. Thanks. Do you know what the Minerva recordings were done from? I have ordered a Victory,and I use DCC sound, but I didn't want to order a sound-fitted one not knowing anything about what was going in it. Will the sound project be made available, or the decoder with it loaded on be made available as a retro-fit by users?
  7. It's getting there. The bonnet isn't fixed in place yet, so the gap between it and the running plate should disappear once it is. The fuel tank is in place and is open at the back to allow the stay alive to be fitted inside. All the doors that are to be fitted are now in place and the framing where the other doors should be will be made and fitted next. There may soon be a 3D-printed Gardner 8L3 to go under the bonnet. I'll still have to make some of the under-bonnet details, including the exhaust and silencer. Current weight: 145g.
  8. I can't find any mention of the sound project that is to go into these, despite a sound-fitted version being offered. It obviously won't be a brand new project, recorded from the real thing, so will be it be made from various existing recordings of similar locos, or will it be a brand new project, made especially and from a single loco? What system/manufacturer will be decoders be?
  9. Thanks for that. I've done the same sort of thing before, but using Oxford diecast boxes. I was hoping to avoid all of that hassle.
  10. There's some good shedology going on here. I think this one, for the shunter/tippler operator, at Royd Hall, is more a cabin than a shed.
  11. I am building the above kit, but there is no glazing provided. Is it meant to be part of the kit, or are they all supplied without? Does anyone produce laser-cut glazing to fit this kit? Thanks.
  12. Thanks for that. Having read that I can see that it's completely useless to me.
  13. I have seen an advert in the latest BRM for these stay alives, which I have never heard of before. I am particularly interested as there are a couple of very small ones, which could be useful to me to fit into small industrial locomotives. The ad doesn't mention them working with Zimo decoders, but is this because Zimo don't have a socket to plug them in, or is there some electronics/operating system reason for this and they simply won't work with Zimo? The picture shows the smallest decoder as being plugged into something called a Zen Stay Alive Control Unit, which negates the size advantage of the small decoders as it is the same size as a sound decoder! Do these stay alives need this Zen thing to operate, or can the plug be cut off and the wires be soldered to the same pads that any other stay alive wires are soldered to on a Zimo decoder?
