  1. Nah, I'm Mr. Shoestring Budget, me I can print things cheaply with my 3D printer - the real "cost" is my time. The RTS kits have taken about 500 hours so far. Based on that, I'd say King's Cross is shaping up to be a 1,500-2,000 hour project. Hogwarts will probably be about the same, I reckon. If only I could bill those hours out, then I'd be seriously rolling in it While I'm an aerospace engineering exec. and I could be pulling down a decent salary, I've spent the last 18 months working for a new startup doing something original and needed in the industry, but that means most of my compensation has been sweat equity and not a lot in the way of "beer tokens". If the company grows the way we think it will, then in a few year's time I'll have enough to fund my own Minatur Wunderland here in Orlando - and then I might actually have a place to put all of these massive model projects that doesn't drive SWMBO crazy! Ross.
  2. I like it! That size would fit my room here at home perfectly But I still want a full N gauge version of the castle which will be massive - based on the original 1:24 scale model at Warner Bros/Leavesden an N gauge model should be roughly 2.4x2.4m footprint, standing 1.2m tall. That's assuming I model the full castle perimeter, the boathouse, the owlery, the wooden bridge, the standing stones and the pathway down to Hagrid's hut. I want to add lots of little details like a swinging pendulum in the hallway, moving staircases, an operating clock in the clock tower, a flotilla of little boats crossing the water, horseless carriages heading up/down the hill etc. And I want to model the village of Hogsmead, the railway station and a quidditch match going on too! Ambitious? Nah! Ross.
  3. I have been slacking in terms of posting updates here recently, apologies to everyone! I've got a number of projects all spinning at present so let me provide a run-down and status for each: 1. The Gresley LNER Teak Restaurant Triplet Set (RTS) in N Gauge: This is finally into Beta testing!! This week I posted the first two kits to Steve (Atso on here) and Alan (from another board). Both packages are winging their way from Florida to the UK as I write this. Once they arrive they're going to put the kits through their paces and hopefully their testing will reveal everything I've messed up and still need to fix I'm hoping to have everything ready to go to start taking actual orders from customers around mid-October. My current plan is to charge about US$80 (£62-ish) per set, plus $15 (~£12) S&H to the UK. On a related topic, I've also been working on the ESU DCC controlled lighting kit for this too and should have something to show on that front in the next few weeks! 2. N Gauge Third/Fourth Rail Chairs: I was approached to build some Third Rail Chairs for a couple of N Gauge modellers. I've done a couple of iterations now and I think a slight overscale of ~20% seems to be a good trade between accuracy and actually being able to see the darned things without having to use a magnifying glass! They are designed to fit any Code 40 rails (such as Micro Engineering), although I will strongly recommend using a rail bender (here's a great low cost way to build one for yourself) to pre-bend all curved rails as the plastic chairs are not very strong and you don't want to use them to stop a tensioned piece of straight track from springing back into shape. Prototypical spacing tends to be around 1 every 6th to 8th sleeper, so a rough guide is to assume one for every inch (or 25mm) of track you want to replicate the Third Rails on and that will get you in the ball-park. Mind, I tend to include a few spares too, just in case any get damaged in transit. They would also work equally well for Fourth Rail too, for anyone interested. I've got two versions; one for flat sleepers like Peco Code 55 wooden sleepers, and another with an angled base that fits sloped sleepers like Peco Code 55 Concrete sleepers. Prices are £5 for a pack of 100 chairs (12 for 10 offer too), and all but the largest orders will be covered by £5 S&H from Florida to the UK. 73c will enjoy this one 3. Travelling Post Office (TPO) - Sorting Van (POS) with Working Net in N Gauge: I have a few bits and pieces now including a coach body, working doors and a prototype for the mechanism that opens the doors lowers the bag delivery arms, and extends a net out from the side of the coach, all driven by a single tiny linear motor that has a 9mm throw on it. The mech is still very early stage and getting the timing right for all the different elements is proving to be really tricky. Right now I'm trying to figure out if it is feasible to open the doors first to allow the delivery arms to come into close contact with 'bags' inside the coach. With a set of magnets in the arms and the bags, I'm trying to have the door open to allow the bag and arm to then come into contact before it then lowers the bag out the side of the coach in the correct orientation. It's a really complex bit of engineering, but *IF* I can pull it off, its going to be an awesome feature to include. But no guarantees yet, I still haven't got it working properly!! ETA for this project is entirely dependent on my job workload - and working for a startup they work you pretty hard - so its going to be no earlier than Xmas, maybe into the New Year before this will be up to a good enough standard to show off. 4. King's Cross Railway Station: Yes, Mike will be pleased to hear that I'm finally back to working on the big beast again! Firstly I've been taking a look at the Clock Tower on the front of the main shed, and working out how to make the clocks work. I've found some tiny quartz watch movements measuring just 14x18x3mm at Walmart for just a few bucks and these are going to drop in perfectly into the 3D printed parts. Right now I'm working on how to be able to turn the knob on the side to set the time. The tower appears to be just big enough for a finger to go in, but I think it's going to be easier to have it simply split into two along one of the obvious seam locations and have easier access that way! I've also been looking at the issue of platforms. I'm going to 3D print a series of edgings and cross-members that will establish the correct distances apart, and then fill the gap in between with plaster. I want to submerge a series of smaller pieces of foam under the plaster too, to make the whole thing lighter. I don't want to do a single long piece of foam, because foam shrinks with age, so a series of much smaller pieces, maybe each only 8"/20cm long, should suffer only minimal shrinkage and shouldn't cause any real issues over many years of service. The next question once this is settled is how to place the parts of the KX structure accurately on top of the platforms. I want the walls to be dead-straight for every build - it won't look good weaving around. The thought does occur to me to embed a structure into the platform, but that might be overkill and simpler options, like a paper template with drilled holes into the plaster platforms at pre-determined distances for each of the major structural columns, might be better in the end. This topic is still very-much TBD. I don't have much in the way of update photo's for this project yet, but should have, soon. I have a few other projects in various stages, which are on the back burner right now too: - 3D printed sleeper bases for custom-build track - Initial rough prototypes built and working. - Travelling Post Office - Stowage Van (POT) - Researching drawings. - Other Gresley Coaches, Full Rake 1928 Flying Scotsman, 1939 Updates, Dynamometer Car - Researching drawings. - Silver Jubilee - Full Rake - Researching drawings. - Coronation - Full Rake - Researching drawings. - Streamlined (Princess) Coronation Class Re-body for Farish Chassis - Researching drawings & need to get a Farish chassis too! - Polar Express Coaches (for personal use, not going to be a kit) - Researching drawings - ETA Christmas 2020. - Hogwarts Express Hall Repaint & Plate Etches - Still building up the nerve to take an airbrush to a brand new loco! - Hogwarts Castle Model - Research essentially complete. Main tower ~80% designed. No other structures started yet. - Magical Mystery Train Tour - On hold until Covid19 situation becomes clearer. - Large SLA 3D Printer - Research essentially complete. Need US$2000 funding. - Next Gen. Enterprise NCC-1701-D Desk Model - Research essentially complete. Design: ~55% completed. And my train collection continues to slowly grow. I've now got a "Cranmore Hall" which will be repainted Red and will soon bear a particularly famous name, an A10 "Flying Scotsman" in wartime black, a garter blue "Mallard", an A1 "Tornado" and a Class 33 "Eastleigh", a bunch of different coaches and I've got my name down for three Pendolino's from the next batch. At some point I really do need to start building a layout... Ross.
  4. Just a brief follow-up - I spent a few hours last night (while waiting for a Delta-IV launch that never happened) trying to find a suitable screen and I managed to do so! I've now baselined my home-grown 3D printer project to use a 10.1" screen. I expect it will take me MONTHS to develop this, and will still cost me the better part of £900 (ouch!) and I will state for the record that it isn't a very high priority project right now, but I can, at least, see a technical solution on the horizon and gradual work is hauling me in that direction. Ross.
  5. Yikes. I just tried uploading a single restaurant coach body to Shapeways to get an idea of their OO gauge/4mm pricing. US$110 (£84) for Fine Detail Plastic. $182 (£139) for SLA plastic. Given that this kit will require 6 different parts of that approximate size, plus a batch of smaller bits too, I don't think this is going to be an affordable option for most OO/4mm scale modellers. I haven't currently got the spare cash to consider buying a large hi-res 3D printer - to get one the size I'd need for this (225mm long coach bodies will require an LCD screen at least 9.1" across) would cost at least £2K for a cheap one shipped direct from China, probably more like double that for a good one. I have started working to build my own home-built 8.9" 3D printer, which would cost a lot less, but I just looked and I won't be able to squeeze this design into it - I'd need a minimum 10.1" screen and I have yet to find anything that would be suitable. The only other solution would be to print each of the coaches in two parts - front and rear. Designing an attachment and hiding the seam would be the trick there. I'll have to experiment to see what results I can come up with, but I want to get the N gauge versions shipped first, so please give me time. Ross.
  6. David, yes, I've been considering 4mm versions. The design is actually done in 1:1 full scale to match the original drawings as perfectly as possible, so I can re-scale them to just about any scale. In 1:76.2 scale the restaurant coaches (the longest single part in the kit) will be about 225mm long. I don't personally have a 3d printer large enough to print that as a single part, but perhaps someone like Shapeways could print it with sufficient resolution. I'll have to check in with them to find out what their limitations are. Watch this space, and if you don't hear anything from me for a month, please don't allow me to forget!! Ross.
  7. I've posted about this on my main workbench thread but I wanted to also put this gratuitous plug here for everyone else interested in 3D printing to see, because, as part of my purchase I now qualify to get a free bottle of resin for any referrals I can generate! So with that said... I've been using an Anycubic Photon (actually a Fauxton) since March and I've *LOVED* what it can do. You can see the result in my thread (see my .sig below), however I just decided to get myself an early birthday present by pre-ordering an even better printer at almost the same cost as the Photon. Phrozen, a Taiwanese company, is currently offering an early-bird special pricing to the first 1,000 customers who pre-order their new printer, the Sonic Mini 4K. The Printer will start shipping in late September on a first-come, first served basis. It features a larger 6.1" screen (135 x 75mm) compared to my Anycubic Photon's 5.5" screen (115 x 65mm) - which will finally allow me to print single-piece N gauge Mk1 coaches on the flat print bed (well, sans the coach connectors which I just have to make as separate pieces). Additionally it looks like it will be able to operate at around 4x the speed of my Photon too (just 1-2 second layer exposure times!), using their own (cheaper) gray coloured resin, which will allow me to print a lot more test parts, which has been the major delay factor in my recent Gresley RTS development project. And the screen is suppose to last 2,000 hours instead of just 400. All in all, I'm hoping it will deliver some serious improvements - at least until I build my own 17" version (yes, that's another project I'm working on). Oh, and it has an X-Y pixel resolution of 722 PPI compared to my Photon's 534 PPI, so it's 35% better horizontal resolution in both directions, with the Z axis having 5x better resolution with as little as 0.01mm layer heights. They have a special offer right now as this printer is brand new and will only start shipping in late September: The first 1,000 customers can pre-order it with this special offer pricing. I live in Florida, so my pricing is all in US dollars. Obviously, UK pricing will be a bit different, but I understand the offer is for all customers both inside and outside of Taiwan, Phrozen's country of origin- just adjust your currency on their website, as appropriate. The offer is to pre-order it for $299, which is $30 below normal, and for just $1 extra they supply it with 1kg of resin (worth $29.99) and a spare FEP film (worth $20) too. Oh, and they're doing a special half-price shipping cost until the end of the month for any of their printers, at just $29.99. Feel free to take a look for yourself, and if you do decide to buy it please use my link below so I get a bottle of free resin! Let me say thank you in advance to anyone who does! http://phrozen3dp.refr.cc/rosstierney I hereby return you to your previously scheduled programming... Ross.
  8. Since I broke my 3D printer's resin vat, the replacement hasn't quite worked right and my prints haven't been coming out reliably. I'm working the issues, but it is taking time to find another sweet spot. Although the back half of the bogie didn't print properly, the front half did, so I can confirm that the latest coupling & NEM pocket designs appear to have resolved all my final design issues for the Gresley RTS project! So as soon as the thin spring material for the coupling arrives from China, and I can persuade my Photon to cooperate, the designs for all the plastic parts for this RTS kit appear to be ready to go out for beta testing! Woo hoo! Somewhat related to my first point above, I decided to plunk down for a new 3D printer for my upcoming birthday next month As part of the deal I get a free bottle of resin for anyone who also buys one on my recommendation, so please excuse my gratuitous plug that follows! I'm getting a Phrozen Sonic Mini 4K. It features a larger 6.1" screen (135 x 75mm) compared to my Anycubic Photon's 5.5" screen (115 x 65mm) - which will finally allow me to print single-piece N gauge Mk1 coaches on the flat print bed (well, sans the coach connectors which I just have to make as separate pieces).

  9. I've gone and broken a part of my 3D printer (stripped the hex of one of the screws holding the FEB film onto the bottom of the vat), so I'm going to have to wait for Amazon to get me a replacement before I can make much more progress on any of my projects. Might be a week or two before I have any real updates :( Ross.
  10. Another couple of deliveries came in today :) First, from US supplier Streamlined Backshop I received a used, but perfectly working, DCC Concepts PSX2 pair of circuit breakers to protect both my main and programming tracks at the top level! In addition to that, I ordered a pack of 27 watt 1156 car bulbs for localised short protection of individual blocks, plus two sockets (one for main, one program tracks) to start me off with. The same order also included some conductive paint for my wheelset pickups on the Gresley RTS kit. I also got a tiny little micro linear servo motor for me to experiment with, intended to motorize the doors and net deployment on my forthcoming Travelling Post Office! A few days ago I also received a bolt of brass 40-gauge mesh for the TPO nets too, but I haven't taken a photo of that. The wires and holes on this gauze look to be just about a perfect match for the real thing and I hope to make a few test parts this week. So my various kit plans are currently prioritized this way: 1) Gresley LNER Teak Restaurant Triplet Set (RTS). 2) Travelling Post Office Sorting Van (POS) with working doors, deployment arms and nets. 3) Travelling Post Office Stowage Van (POT). 4) King's Cross Station (actually working on this all the time, in amongst everything else). 5) Sleeper Bases for custom track (a new project that will really help with a complex layout that I'm making). 6) Silver Jubilee RTS. 7) Additional Gresley's & Silver Jubilee coaches to make full rakes. 8) Other stations. It's building into quite a list :) Should definitely keep me busy and out of trouble! Ross.
  11. LOL! Actually, in all seriousness, I know loco's were repainted black - I just picked up a WT Black Flying Scotsman - but was any rolling stock ever repainted (black or other colours) during the war, too? Ross.
  12. So my latest design for the electrical connector appears to be working brilliantly Thought I'd share a couple of pics... *Follow-up: The wires sticking down from the bogie won't stick down like that when in use - you just push them up into the Kitchen car, and if necessary, you can fill the recessed area with some blutack. Ross.
  13. I've only got a very basic loop of track so far, really just a program track fitted on a temporary foam base. Until just recently I had hardly any rolling stock, so hadn't invested much time in getting the DCC electronics working - although I have been gradually building up stocks of all the bits I will need. I finally got around to tackling the DCC++/JMRI install two days ago. It was very frustrating at first, being unable to get my Zimo and ESU decoders to respond, but I have finally solved all the issues (well, the ESU units still won't acknowledge anything back to the Arduino DCC++ controller, but it still accepts the programming and does everything it's supposed to do). Everything now appears to be working! And it was just in time too, because my A10 Flying Scotsman in Wartime Black (which will be the main hauler for my Gresley's including RTS) just arrived - as did the Rapido couplers that I know a few of you have been waiting to see! So, right now I have a Hall, an A4 Mallard, this A10 Scotsman and my ESU lighting system for the RTS, all configured and working properly - and they're all controllable from my phone! Woo hoo!! I still need to configure my Octopus III servo controller for up to 8 turnouts - but I think I need to get some turnouts first And now that the Rapido's have arrived I'll start working on the couplers for the RTS - which should be the last major task before I can look at a 'release'. Ross.
  14. Cheers Phil, I found a few options that should fit, even in the N gauge coach. Based on the size of the doors (and assuming they will all have to slide the same way), it looks like I need something with at least an 8mm throw, so something like the Spektrum S2000 might be a fair option. There are also some really small servo controller boards such as the Trinket Mini - and that would provide a lot of capability. If I need something even smaller, the DasMikro DSK-142 has potential too. I'll grab a couple of examples and play around to find a suitable combination. Finding a reliable source that won't dry-up too quickly will be an important factor. The next month or so is likely to be quite busy for me at work, but I'll gradually pull this together whenever I have time. With the F1 season running, I should get at least 8 hours to work on this stuff each week! :) Ross.
