simon br blue Posted May 7, 2014 Author Share Posted May 7, 2014 (edited) Time for another update, I've done some more work on the PBA and have now glued the pipe to the body and fitted the top hatch, now it just needs a clean up and some paint. I have used the replacement parts printed with the previous order to replace the broken details on this original shell, also visible in the photo below is one of the sprung buffers test fitted. Another wagon I've done some work on is the Campbell's PVB which has had one side glued on and a plasticard roof fitted - I made the mistake of cutting the plasticard too narrow which didn't make it easy to glue one side down which in turn meant I had to do some filling to get it looking OK. Once I glue the other side on it will also be ready for the paintshop - I may need to add some weight to this wagon as it's quite light. I received another order from shapeways earlier in the week and this had a TTA tank wagon chassis (more on this in the next update) and also another new type of wagon to add to the fleet. This was in the form of a BDA- I already had the correct bogies so decided to try and draw one using a basic drawing from a weight diagram book and the Bachmann model. The wagon was nice and simple and easy to draw and not printing the deck makes it cheap for a large wagon. I did make one mistake and forgot to leave holes at the edge where the straps would feed through the deck onto the ratchet points to secure a load but this shouldn't be too noticeable when the deck and a load is added. One problem I will need to contact Shapeways about is the shape of the wagon - it's bowed up in the middle (same as the Bachmann model but not something I did when drawing the wagon), I guess its from some sort of shrinkage during/after the printing process to do with the underframe support framework but could be wrong. The removable bolsters have printed well as a separate part and even fit over the spacers I added to the wagon side to help position them. Also after seeing the 15% off WSF at the moment I might have to get another order in soon. Edited May 7, 2014 by simon br blue 8 Link to post Share on other sites More sharing options...
RMweb Gold Robert Shrives Posted May 8, 2014 RMweb Gold Share Posted May 8, 2014 Hi The BDA is very good, without deck it looks like the "burnt out" version I saw on a freight in South Wales after brigade attended to the well alight waggon ! Will the crown come out under load? The real ones -well some had a crown I saw at Bescot years ago. Would a 1/32 be possible ? Robert Link to post Share on other sites More sharing options...

simon br blue Posted May 16, 2014 Author Share Posted May 16, 2014 (edited) I've made the deck for the BDA from Plasticard, just cut out and scribed some planks on. The pictures below show the deck and the stanchions, these aren't glued down yet - the deck is held down by the same clips that help to align the stanchions. Only thing left to do is glue the parts down (hopefully I can glue the deck in a position that helps remove some of the hump in the wagon). Also whilst making the deck I did notice a printing fault on the model which I've passed to Shapeways to investigate. I've also done some more on the TTA tank. I've drilled an pushed the fittings into the tank barrel, this did show up one mistake I'd made when drawing the pipework as I'd made the filler pipe too short, but everything else looks ok and I've ordered another from shapeways. The fit of the rubber hoses looks quite good but may need a piece of wire inserting to allow them to be connected or disconnected easily. Just needs some etched walkways now Edited May 16, 2014 by simon br blue 2 Link to post Share on other sites More sharing options...
tomstaf Posted May 16, 2014 Share Posted May 16, 2014 Oooh, I like the BDA Simon If you've got a wire brush, run that across your decking in random lines and it'll scribe a wood grain effect into the plastic card. Cheers Tom Link to post Share on other sites More sharing options...
Marbelup Posted May 18, 2014 Share Posted May 18, 2014 Hello Simon Re the bowing issue with your flat wagon, I wonder if this idea would help? With some of my S scale wagons which don't have a full body for rigidity, I have been building in holes through the underframe members to allow me to slide in lengths of steel rod to provide some reinforcement. My wagons are printed in i.Materialise Prime Gray which does have a tendency to "sag" when thin sections are unsupported. The attached screenshot shows the holes just inside the side sills of a flat wagon. I draw a cylinder to represent the steel rod 0.5 mm shorter each end than the length of the wagon. To insert the rod, I drill through the remaining 0.5 mm at one end, then fill the resultant hole before painting. I am using steel rod 1.85 mm diameter and I make the holes 2.2 mm diameter to allow for the tolerance of the 3D printing process. Obviously, the rods could be proportionately larger in your scale. I realise the buffers may well get in the way with your wagons - mine don't have buffers, which makes things easier. 2 Link to post Share on other sites More sharing options...
simon br blue Posted May 22, 2014 Author Share Posted May 22, 2014 Thanks Richard, I'll have a look at your idea if the reprint of the wagon comes back looking the same (I'm going to get another print after I found some issues with the current model- not related to the bending). I noticed some marks on the model sides - as can be seen below the wagon side almost looks like wood instead of metal after a coat of paint. Also visible is a test deck part painted to represent weathered wood. Also painted recently were 2 PVB Campbell's soup wagons (4 and 7mm). I've done a bit more on the BAA, I've test fitted the central framework made from 2 sections of evergreen I beam. I also redesigned the bogie mounts to clamp the beams and intern the mesh deck to the underside of the wagon. The first picture shows the wagon without the deck and the second with the mesh added. I will probably end up weathering this as I've not seen a picture of the deck looking clean. Another wagon that's had a coat of paint this week was the PBA. It will need another coat of white but it's getting there. As mentioned the other week Shapeways had 15% off WSF orders so I took the opportunity to order another hopper body along with a chassis. I went for a 7mm Redland PGA wagon with the hopper designed so that it could also be used for a BIS PAA wagon, this design is basically a 7mm WSF version of the 4mm FUD models printed the other year. I might get some hopper bodies cast in resin as a rake of Redland hoppers would look good behind a Heljan class 60. 5 Link to post Share on other sites More sharing options...

Guest Ejennings Posted June 20, 2014 Share Posted June 20, 2014 If you are planning to buy 3D printer machine, then go ahead. Some manufacturers offer unassembled kits which ranges from only £300-£600. And yes, soon 3D printers will be available in every household and can be used for resin tooling. For our first project, we created 3D model of padlocks and keys for our rooms made up of 3d2print’s nylon material. Link to post Share on other sites More sharing options...

You obviously haven't got the message yet so the next step is to say to readers....... Don't buy anything off 3d2print - there are more ethical businesses for you to choose from.

simon br blue Posted July 23, 2014 Author Share Posted July 23, 2014 Time for another update. All wagon progress this time. Firstly I've added a deck and primed the OTA wagon. Just needs a topcoat and some logs. I have also printed another BDA wagon - the second type with disc brakes and different bogies. I got this done as I got some store credit for the original one that had poorly printed sides (something to do with some poor quality powder they had in one of the printers). In my most recent order I got a pair of Y25 bogies printed (the cast type?), I've not got a wagon to put on top of these but I did them as a test with one printed normally in WSF and a second printed in WSF polished to see what the difference was and see if a bogie could withstand polishing. Have to say I'm impressed and it looks good and there's no damage, some of the bolt head details have been rounded off a little bit but overall happy - next order I'll get some standard Y25's printed to see what they're like and if they can be printed (the one this time was done with 'print it anyway'). First picture shows hte smooth bogie and the second shows the difference between the two - particularly noticeable on the slope on the top of the frame which is a bit fluffy and stepped in the non polished. The polished surface is also nice and smooth to rub. Not pictured but I also ordered a set of buffers polished and they turned out OK as well and should slide easily when sprung. A wagon that I've drawn but not printed yet is the Railiner experimental curtain side wagon. This will use a cut down Campbell's soup cast curtain side with a plasticard roof formed over the frame the same as the Campbell's wagon. The wagon chassis was modified from the DOW chemical tank wagon as the original used a ferry tank wagon chassis. One issue I did have was finding a set of drawings as the BR diagram had a number of errors including the off set wheelbase, roof shape and height. The final new wagon I've had printed is a Polybulk. I drew this using a combination of a wagon diagram, a side on picture and some measurements from the Bachmann model. To keep costs down I decided to draw a framework skellington that I could add plasticard to. I added groves to fit the plastic into at the top and bottom of the hopper and printed the discharge doors and hand wheels separate. When it arrived there was a problem with the model as the end handrail was damaged but I was able to get store credit for a couple of euros to allow a replacement handrail to be printed with the next order. Adding the plastic to the sides wasn't as easy as I'd hoped - was a bit like trying to squeeze a bike tire onto a flexible bike wheel using cocktail sticks instead of a pair of spoons. I did get them in place eventually but have already made a mk2 (pictured at the bottom) with less framework but hopefully a stiffer construction. I also need to modify a Y25 bogie with bigger/thicker brake shoes. Not sure what livery it will be as hoped I could get a 7mm set from Fox transfers for the traffic services livery but would need to order 25 sets to make it worth them resizing their HO ones. Once the ends have had a sand I'll have to sort out the little bits of damage before sorting the livery anyway. 7 Link to post Share on other sites More sharing options...
simon br blue Posted August 12, 2014 Author Share Posted August 12, 2014 Time for another little update on wagon progress. This time it's 2D printing. A the wagons have progressed I've been looking for ways to finish them off and only found limited transfers available for the wagons which made me think about drawing my own. I did this in Microsoft paint - basic but simple program, scaled and printed using Microsoft word onto decal paper bought off Ebay. First test was some decals for the Dow chemical tank drawn by working out dimensions and colours from pictures. Picture below show the transfers (printed on clear paper as the tank body is white) on the test tank, not in the correct position but just to see what they looked like and what detail I could get with my desktop printer. The second wagon tested was the nearly finished CO2 tank, with transfers made up in same manner as before. both the tank wagons had the stripe painted on but in future I might try printing the stripe. The final wagon to test the new method of transfers on was the PBA Tiger. For this wagon I had previously purchased part of the transfers from precision labels after they had scaled up their 4mm versions. This had the ECC logo and tiger branding with a couple of other decals but I had to draw some of the extra lettering and also required the blue stripe. I drew the stripe in 3 parts and added this to the model - this was easier than masking the stripe (which is currently on the other side of the model but didn't turn out very well). One slight issue with the stripe is the patchy colour of the blue (probably to do with the way I coated the decal paper and maybe the micro sol/set) but when looking at the weathered prototypes it looks ok as most seem to have weathered quite badly in real life. The tiger only needs a couple more transfers on this side and the other side completing before it'll be ready for some weathering. 4 Link to post Share on other sites More sharing options...

simon br blue Posted October 1, 2014 Author Share Posted October 1, 2014 Time for another update. Some developments and some new wagons but the biggest news is the soon to happen Shapeways price change, which will make a lot of my models too expensive to realistically build up a rake of wagons. One wagon that I've drawn but not had printed is a Procar 80 car transporter. To keep the price down (not that it matters much now) the deck was open and I would use small scale mesh to represent the mesh the cars would drive on. The railings are separate fittings and the bogies were redrawn from the previous order when I tested the polished WSF bogies. I might still try to get one of these printed before the prices change. Another wagon that I drew and am currently getting printed is the a TTV LPG tank. For this tank I've also drawn some transfers to put on the tank. Another wagon set that I was working on but may now have to rethink was the Redland/Lafarge Self Discharge train. The first wagon drawn was the KJA discharge wagon, this was easily the most complex wagon I've drawn with the conveyors, engine and hydraulics. The wagon was designed so that the discharge conveyor would pivot and raise and lower. I may still get one printed before the price rise - it will still cost about £100 to print but alot less that it would after the 7th of october (£180). I I'm part way through drawing the hopper wagons - starting with the centre wagon and then modifying that to made wagons at the end of each rake.

simon br blue Posted October 29, 2014 Author Share Posted October 29, 2014 Bit of an update, Done some work on a couple of wagons, firstly added some resin sides and a roof to the Railiner. Next step will be to give it a paint and make some transfers. Some more progress on the Grainflow PAA, I've cast a resin hopper body, next job will be to glue the top and hopper together before painting it. A bit more progress on the Campbell's soup wagon, I've added some transfers to the 4mm version. The main Campbell's logo transfers and data panel were produced for me but the others are home made. Now onto some new arrivals - My order placed before the Shapeways price increase turned up with some new and updated wagons. The two updated models are the Campbell's wagon which I've made the end and roof stiffer, this is also one of the models which has gone up in price allot but interestingly the price doesn't go up much more if I make the roof and ends solid. The second modified model is the Polybulk which was modified to make the sides stiffer and to add a solid walkway as this area was not much more expensive to make solid than to have open in the original model. The other 2 models are new and were printed because the price was a bout to double on them. The Procar 80 car transporter was done to see how a long model would print and it looks to have turned out well and isn't distorted. It should also be good addition to the speedlink wagons as they didn't always run in long rakes like the other transporters, the bogies are also the same as the one on the PXA wagon. The PXA wagon has turned out well and I'm particularly impressed with the look of the conveyor belts. It was printed in several part separately and they won't all line up correctly on the wagon until the plastic deck has been added. Most of the detail has come out well on the engine and pipework. The final picture is of some beads that I found wedged in one of the polished bogies - I guess its what Shapeways use to smooth/polish models, the feel like they're made of ceramic.

RMweb Premium Steve Purves Posted October 29, 2014 RMweb Premium Share Posted October 29, 2014 Would you consider doing the Redland kit in N gauge? after the petfood wagons I am looking at the self discharge train.... Link to post Share on other sites More sharing options...
simon br blue Posted October 31, 2014 Author Share Posted October 31, 2014 Would you consider doing the Redland kit in N gauge? after the petfood wagons I am looking at the self discharge train.... I think it would be very delicate in 2mm when printed in FUD, not sure if other finer printers could print it of again if it would be too thin especially the conveyor. I did upload a 4mm FUD test and according to the Shapeways upload tool it would be printable. I'll have to see what the hoppers look like when I've drawn them as they should be thicker and easier to print. Simon. Link to post Share on other sites More sharing options...
RMweb Gold Revolution Ben Posted October 31, 2014 RMweb Gold Share Posted October 31, 2014 Hi Simon, I must admit I'm chewing my lip in envy at the Redland vehicles. Like Steve I'd love to see them in N. I take the point that as you've done them in O they would be too flimsy, but what if the main bits were beefed up a little and the fine bits simply removed and done with glued on photo-etches? cheers Ben A.

Just as I thought. Could a hopper and chassis be printed with an etch done for the framework. Wouldn't know where to start personally but would definitely be interested in a rake (or 2). Those and the ketton/castle cement PCAs (that TPM used to pruduce) would complete my missing links then! I did think about building a master and resin casting a kit but dont know how successful an N gauge hopper would cast? Link to post Share on other sites More sharing options...
