Modbury - 2mm Finescale (Brunel's Baulk Road)

I would recommend that Frosted Ultra Detail is your friend here. The White Detail material is very coarse when compared and will struggle to print details below 0.3mm. Also the print depth of FUD is finer than either of the other two requiring less post printing clean up and smoothing.

Another vote for 'Frosted Ultra Detail'... the saddle tank I showed you was made from it, it will make all the work with the rivets worth it!

 

Good luck with the mysterious world of printing, it will make more sense as you make more progress!

Sorry to hear about the set-back, Ian, but impressed tht you redrew it all. Sometimes it seems that persistence is the most important skill a modeller needs.

how do you design something like that and get all the dimensions?

Mikkel,

In all honesty having to re-draw it was in the end beneficial - I had learnt a lot during the initial drawing, so with the benefit of experience the re-draw was much quicker and the end result is probably better. I've uploaded it onto Shapeways, and now need to wait until pay day to order some. I've also made it available to others and allowed downloads too so that if others would like one, or want to make improvements to my rendition they are free to do so (I'm not proud :-)).

Rheneas,

I had a drawing of the van in "GWR Wagons" by Atkins, et al. This gave the general dimensions, obviously you have to take into account the thickness of the sides (I drew the ends to fit between the sides - hence the vertical line on the ends a mm or so inboard of the outside frame). A couple of photo's helps in the size positioning of the detail, some of the elements were re-drawn as they didn't quite look right. Even the positioning of the bolt heads were jiggled a bit so that they would go into the frames where it made sense (as originally drawn they would have been too close to the end of a framing piece to have been secure in a real wagon).

For this particular prototype it's probably also worth consulting "A Pictorial Record of Great Western Wagons" by Jim Russell. The drawing isn't quite as useful (no details of the underframe), but the photograph (end view) is helpful.

I have heard of company policies (I've yet to work somewhere that has a policy like this but some colleagues have) that require the re-creation of models from scratch once the design is approved. The idea is that you will make it better a subsequent time.

I read somewhere that the CAD software gives options for thickness to print.

 

Waht 3-D drafting software do you use?

Dazzler Fan,

 

I am currently using Google Sketch-Up. I don't know about "options for thickness to print", as effectively I am building up cuboid shapes to represent the side and end panels of the wagon which I then put slots in to represent the gaps between the planks . For this wagon, I made the slots 0.15mm high, with a depth of 0.2mm - the side panel I made 1mm thick. For subsequent wagons I will try making the side and end panels a little thinner (as the Cattle wagon and Brake van have visible insides).
