They look good, what did you use to make the joins in the tank lagging?

Thanks Simon,

 

The banding was made with Salters 0.030" x 0.030" microstrip, attached to the barrel before painting.

 

Thanks for your help with the wagons, really pleased with how these have came out.

Cheers for the tip about 51L/wizard models, I purchased some ferry fittings and various etched wheels.

 

Regarding the Wisbech and Upwell models, I'm still working on them, the balcony railings are the weak point at the moment, maybe need etching or laser cutting.

 

Work has also continued with the various Polybulk wagons.

 

I rescaled and printed a 4mm version of the E443 slab-sided Polybulk, the body is grey PLA and printed in 2 parts on the Balco printer, the details are grey resin printed on the Form 2.  The bogies are Shapeways Multi Jet Fusion Y25 bogies.

The other 4mm Polybulk that's nearly finished is the Malt Distillers version.  Balco PLA 2 part body, Form 2 grey resin details, Shapeways WSF Y25 bogies. Etched ferry loops and brake wheels from 51L/wizard models.

Moving up in scale the 7mm Grainflow Polybulk is nearly finished.  Similar to the first Polybulk its made with a Balco PLA 3 part body, Shapeways WSF Details and Y25 bogies.

Finally for tonight is the 1/32 Grainflow polybulk pictured with the 2 smaller versions (which makes the 4mm version look tiny).  It's made the same way as the 7mm version with Balco PLA 3 part body, Shapeways WSF Details and Y25 bogies.

Hi there,

 

Have you done anything about transfers for the Malt Distillers Polybulks? I've got 3 modified Electrotren wagons in various stages but am stuck on the transfer front.

 

I think there's all look great - I've got a bit of a thing for Polybulks!

Steve from Railtec has mentioned producing these previously.  Hopefully he can produce these and the Grainflow decals.

 

There are some Polybulk decals in the catalog already, though without reading the previous several posts they may not be a 100% fit for what's needed. Limited resources recently been working on the CO2 distillers, which are an absolute can of worms as there are at least 3 variants, so packs are being made to suit the specific variant which is available on Shapeways (smaller style bodyside anchor box without corrugated vehicle ends). Doesn't help that there's little consistency in the sizes and styles of many of the markings too. Probably at least a full day's labour so far just on researching, graphic design of all the elements, testing and manufacturing a suitable pack for the CO2s alone. And people wonder why there are so few transfer manufacturers...

Cheers Steve, hopefully get some of these at Warley.

 

Pictures of a couple of more wagons below.

 

First up is the 7mm PAA ICI Urea hopper with White Natural Versatile Plastic chassis with PLA hopper, Form2 Grey resin hopper top doors and wire pipe runs.  I struggled to find a good colour match and ended up mixing up a similar colour.

Next wagon is a 7mm TUA Carless tank wagon, White Natural Versatile Plastic chassis, tank ends, ladders and walkway.  63mm plastic pipe for barrel with masking tape used for tank joins and homemade transfers.  This is the shorter tank, I now have a longer wheelbase version to build.

Another new wagon thats nearly finished is a 7mm KFA Warflat wagon fitted with GPS bogies.  Body printed in 2 parts in grey PLA printed on Balco printer.  GPS bogies and bufferbeam printed in versatile plastic from Shapeways.  Air brake fittings and vehicle chocks printed in clear resin on Form 2.  Handbrake wheels and securing eyes not fitted yet.  Its been identified that the bogies are too narrow and I've now drawn some wider ones.

Hi

 

To save you reading back through the previous posts they aren't the same. These are the other ones (diagrams E518 and E581) I mentioned when you kindly did the diagram E442 version. 

 

Cheers

I've used 3D printing as well. Off the machine, the parts do come out rather grainy, with some layering evident (this is inherent in the way the machines work, and a lot better than it used to be!). However, a blast of primer followed by some rubbing down usually gives a good surface finish. It does, I am finding, mean that you're better off leaving off rivet detail and adding it afterwards (unless you want some really fiddly rubbing down to do!) I've recently had a couple of wagon bodies prototyped as a test exercise (there's a pic of the raw body on my blog, will put more as the finishing and chassis construction progresses). I'm currently working on the CAD for a loco body for an industrial shunter (below), and will let you know how things go!

In terms of software, something like Google Sketchup is capable of producing the required files. There are other free packages available, but you tend to get less errors and issues with a high end CAD package. That said, if I didn't have access to one (Solidworks) in work, I certainly wouldn't shell out the couple of thousand it costs!! In terms of time, I find I can model something complex on the computer in a fraction of the time it would take me to scratchbuild it. Of course, it's not as much fun, but there's still a fair bit of work involved in the finishing and detailing process.

 

Apologies for hi-jacking the original thread, but there seemed to be a lot of interest in the technology, so I thought it would be worth sharing my experiences.

Regarding using free CAD packages Fusion 360 is quite  powerful & if it is for non-commercial use you can get it for free + a GREAT HELP is there are many  Fusion360 tutorials on You Tube!

Hi, yes I can make models available in 4mm, let me know what you're interested in,  the only issue is that the models wont work out particularly cheaply as to get reasonable detail the more expensive materials will be required.

 

Below are a couple of more wagons suitable for Kings lynn, another 7mm Polybulk in the original POLYBULK livery.  This is one of the original Shapeways printed models with platicard sides added, I did get a couple of these but with the price increases at Shapeways it made sense to develop the PLA printed version.  The transfers are Railtec (E442 Polybulk transfers) for most of the wagon with homemade decals to finish off. 

 

49224741573_ed06be1f8f_k.jpg7mm Polybulk by simon br blue, on Flickr

 

Next wagon is a 7mm Ferry tank wagon used for chemical traffic to DOW Chemicals a Kings Lynn.  This was actually printed a couple of years ago but only finished recently, the chassis and ends were printed by Shapeways in versatile plastic, Shapeways Fine detail tank hatches, PLA printed top cover and plastic pipe for the tank barrel.  Finshed with homemade transfers.

49101083681_9e37eddeb2_k.jpg7mm Ferry tank by simon br blue, on Flickr

 

I have also recently been painting a couple more 7mm mineral wagons,  7mm HTV hopper with PLA body and Form 2 black resin test chassis (ZDV) and shapeways chassis (HTV's), homemade transfers, weathered with MIG and model air acrylics, the only parts not fitted yet are the handrails.  The ZDV was weathered using MIG and model air acrylics and MIG streaking rust affect.

The 7mm 16t mineral wagons are Lima body with Shapeways chassis, various weathering effects used to experiment with finishes, again weathered using MIG and model air acrylics and MIG streaking rust affect

I'm new to this thread, so apologies if I'm raising something outdated.

I'm specifically interested in Wisbech & Upwell items in 4mm (00) scale. By a very devious Google route I ended up here and saw your 04 & luggage van (etc). Are they available for sale? I did manage to find you Shapeways link but can't see them there.

Hi Stewart,

 

The Wisbech & Upwell project stalled when Shapeways withdrew the material the models were designed to be printed in.  I will look again to see that can be made available in other materials.

Time for another update,

 

Firstly some wagon progress, the 7mm Redland PGA hopper now has most of the transfers applied, Fox transfers for most of the details with homemade Redland decals.  Additional underframe details added after looking at the Cavalex models version.

Next up a 7mm Polybulk in the original POLYBULK livery, this is the Shapeways version printed in versatile plastic with plasticard sides added.  The transfers are mostly Railtec (using the E442 pack) with the rest homemade.

Next wagon is an Albright and Wilson TUB Phosphoric Acid tank.  This was printed several years ago but only put together near the end of last year.  just requiring transfers which is the holdup now as I don't have a way of printing the white lettering.

Another tank wagon nearly finished is a TTA ICI Caustic Soda tank.  This is a updated model from the original Soda tank with a simplified chassis with separate underframe fittings to reduce the cost when printing through Shapeways.  This tank also requires transfers and then some weathering as the colour looks too bright.

Another update,

 

Been doing some transfer application recently in 4mm and 7mm.

 

First was the 7mm TTA Caustic soda tank with transfers from Precision Labels.  This is the first of the TTA that I made and is painted in a darker colour to the most recent wagon.

49813660048_5a4a667f0c_k.jpgTTA Caustic soda tank by simon br blue, on Flickr

 

The next wagon is one of the 4mm Grainflow wagons, this wagon has the Fox transfers Grainflow decals although I've not finished all the smaller elements but took a couple of photos when I'd finished the other wagons.

fantastic models and great use of 3d printing technology.

 

Have you considered doing cement tankers in 7mm? either the straight tank variant or the V shape ? I appreciate the latter is occasionally available elsewhere, but probably something very useful for 7mm modern modellers.

Time for another update.  I've not had chance to get the previous prints painted but hopefully the weather will improve and warm up a bit soon.

 

On the drawing front I've nearly finished another Wisbech andUupwell item of rolling stock GER brake no.16, render below shows current progress but its been harder to find photos and detail compared to the locos or modern wagons I've done previously.

 

GER%20brake%2016%205.1_zpscoy0ttlg.jpg

 

 

 

 

I have some feedback in relation to this model (in 4mm) on this, which I hope you will take as constructive. I think that a corrected design printed in a better material than is currently available, could result in a very good model.  I am sorry not to have offered feedback sooner, but the beauty of 3D is ability to make changes. 

 

The model appears only available in grey "PA12".  This material seems every bit as nasty as WSF; it is rough and captures the detail poorly, e.g. no relief on the door vents.

IMG_8810.JPG.69ccb8a842153be01d48379bde377d29.JPG

 

 

Overall, I liked the design, and it was good to have a floor and the underframe and brake details.

 

There are some issues, however. This van was converted from an 1875 GER coach, and a better knowledge of coaches of this vintage and GE design would have assisted in the design of this model. There are plenty of pictures of old, mainly grounded, coach bodies of this ilk on the web.

 

The solebar looks a little too recessed, or, perhaps, the upper foot-board too shallow, as if steel channel was intended, whereas this is a wooden solebar prototype.  The upper foot board needs to extend outward further.

 

The headstocks, too, were wooden and, thus, should be deeper than on the model and, also, would have had rounded profile ends.

 

The body has some serious issues in two respects.

 

First, the style of the body panelling is incorrect for this vehicle:

 

  • The waist should not feature the recessed panels with radiussed corners.  There should be square-cornered raised beading with a slightly rounded profile.  This is very much a feature of 1860s and 1870s carriage design.  The conservative GE carried it into the 1880s.

 

  • The panel style above the waist is wrong.  The door lights, quarter lights and blind vertical panels above the waist should have square bottomed corners and large rounded (in fact triple-radius) tops. This style persisted on the GER until the second half of the 1890s.

 

Second, there are elements of the body treatment that do not reflect any carriage building practice of the era:

 

  • The groove representing the doors is carried all the way to the top of the body, making the doors on the model appear the full height of the coach. Doors terminate below the eave panels, or the coach falls to bits!

 

  • The panels above the waist are framed with raised beading, almost like a window bolection, with gaps between it and the adjacent panelling that should not be there; shades of the egregious Hornby 4-wheel coach.

 

  • The upper part of the non-brake end is wholly wrong.  I appreciate you could not find a picture. 

 

It is difficult to derive the necessary details from pictures of No.16, but, if you know what GER coaches of the period actually looked like, you can understand what you are seeing better when you squint at little pictures and partial views of No.16.

1826465888_GERWUT06-Copy.jpg.7af056efe374f6d81901ece9d327b199.jpg

 

Looking at the picture above, you can discern all the features I've pointed out.

 

This picture is of a GE coach of the same period of construction and usefully shows much more clearly how things would have been on No.16, including:

 

- Rounded thick wooden headstock

- non-brake end

- waist beading

- upper panels and windows

Again, trying to be helpful (!) Please feel free to PM if you want to discuss.

Hi,

 

Thanks for the comments, always good to get feedback.

 

just to reply to the comments above-

 

These models were originally resigned for the Shapeways black resin which they stopped using a couple of years ago.  I only made the models available recently as the cost for PA12 was significantly reduced recently meaning that some may want to order one.    Shapeways SLA resin material would cost about £75 and the Fine Detail plastic (previously FUD) would cost over £60, I can make these available if anyone wants them but would have to check if they meet the design guidelines.   Below is a text print that was printed by Shapeways in their HDA resin before they pulled the material.

 

W&U no.16 4mm

 

Now that they have been pointed out I can see the issues with the bodyside and think some of these carry over from elements copied from previous Wisbech and Upwell coaches and looking at some other vintage coaches and as mentioned I could't find a photo of the non break end with the door.  I think the chassis issue was because I struggled to find decent photos and used the photos available of the brake on the Mid Suffolk Railway which doesn't have the original underframe.  

 

All the models available on Shapeways can be viewed in their 3D viewer which may show up any detail issues on other models and as mentioned most details can be easily modified when noticed.

Hi,

 

Thanks for the comments, always good to get feedback.

 

just to reply to the comments above-

It's a nice model, badly let down by the material. It's certainly worth tweaking to bring it in line with the prototype, if you are interested. 

 

Then, perhaps, you might consider selling the right to print, because a much better print could no doubt be obtained on a home Photon or via a hub?

 

When out of lock-down, the factory that does the Rails SE&CR van offers an SLA service; it would be very interesting to know the cost of printing this coach would be. 

 

They could print them for you for sale.  Yes, you have to do post and packaging, but I would suggest a better quality than Shapeways and at less cost.

Hi, like most people on here I don't sell or give away my stl files.  I have a Form 2 SLA printer but it would struggle to print the coach and to remove the support material easily.  I models in this thread are made for myself as a hobby, I make them available for others if requested.

 

A more modern item of stock that i was able to take plenty of reference photos of is a 156 DMU.  I wasn't able to find any detailed drawings but using the drawings and some side and front on photos I've made some drawings although there are some more detail to finish like the interior and sorting out a way of making the window frames - I'm thinking possibly laser cut frames or an etch.  I did test print of the basic shell printed in 2 parts with the main body and a cab end with gangway printed as one part.  I then printed a test of the snowplow and coupling on the Form 2 and a bogie on my Balco printer.  I think the best way to print this would be as a one piece shell on Shapeways with separate details bogies and under frame.

Understood, though that's a shame.

 

Your HDA print looked very nice, but do you think I should have paid c. £50 for this ?  Would you?

 I realize you are disappointed with the model, I think the current price is £38 for the model but would I pay that for a similar print in PA12,  yes I would and I currently have some 4mm models on order with Shapeways but I realize that PA12 that is a compromise between design limitations, surface finish and minimum thicknesses.  Hopefully 3D printing will continue to improve where prints like the HDA model in my last post can be produced without the need for support like the current SLA models,  without support residue marks like the Fine Detail Plastic on Shapeways and without the layering or lower resolution seen on FDM printer.
