Yeah that's a good idea! In any case the potholes and larger gaps will have some light coloured gravel added into the bottom to represent the asphalt base.
Oh yeah I can make that....

I've been making small amounts of progress on this, but nothing photo-worthy yet. My Pegasus Gothic building kit arrived, along with the resin furniture. The building will work quite well, but will still require a lot of modification and up-detailing. It's a snap-together kit so you can't expect too much from it ;)

The resin furniture I was a little bit disappointed with. The level of detail is far less than the painted pictures conveyed and the casting quality isn't as high as I'd expect. They will do the job, but again I'll probably have to do some up-detailing.

The next thing I need to sort out is a concrete texture for the kerbing and sidewalks. Now although model train enthusiasts argue that the texture of concrete is so fine that it wouldn't be noticeable when scaled down, I'm of the firm belief that with modelling for pure aesthetics (as opposed to maximum accuracy) certain features and textures need to be exaggerated. Like the same way that 28mm figures are proportioned with certain features exaggerated.

So I've been looking around for a way to give my styrene sidewalks and kerbing a concrete texture. There are 4 possible techniques that I feel give appropriate results:
  1. Casting the details in actual plaster. This looks the most authentic because it actually is!
  2. Apply a coat of impasto medium (an acrylic medium combined with a fine powder to give texture). Probably needs sanding to a smooth shape once cured.
  3. Coat styrene with styrene cement and stipple with a brush.
  4. Stipple on Mr Surfacer 500. Might need some light sanding when cured.
I've just done a test of the last two tonight - I'll hit them with some grey paint tomorrow night to see how they look but I'm not feeling very confident (definitely not with the styrene cement technique).

I'm not going to screw around casting plaster (that would make the diorama quite heavy too) so the impasto medium is the only other technique that I think could work. I've got some gel medium so I might just try mixing it with some dust and knifing it on. It only wants to be a very thin layer.

Anybody got any other suggestions?

Oh and during my googling I finally ran across the article that gave me the inspiration for my asphalt technique: http://www.armorama.com/modules.php?op=modload&name=SquawkBox&file=index&req=viewtopic&topic_id=170011&page=1

Im lost on the concrete Buddy as Those are the same options I would say. only other thing is MAYBE some wood glue and fine sawdust mix used as a thin spackle but That would be extremely messy and I doubt worth the troubles.

Maybe lightweight Hydrocal casting?? its super light but not durable, so be careful if you use it. you should be able to get it at RR stores Easy.

And Ace find with the Road. Im LOVING that Idea and look and have bookmarked that for my own use.

Yeah, hydrocal is pretty commonly available. But the weight of plaster isn't the determining factor; it's just the amount of screwing around needed to make all of the formwork and everything to cast it into. Woodglue and sawdust is another idea, but really not much different to the impasto gel.

I've been doing some more work on the Warhound project of late. The last fortnight has seen some major work on the base. All of the plaster work is done (I'm using Hydrocal tinted with a little black paint) and has been cleaned up (scraping and sanding). I also scribed all of the details into the concrete and then laid the asphalt. The asphalt is a mix of plaster, fine sand, PVA and black acrylic (I just used cheap discount store acrylic and ran out of it near the end). It's actually really difficult to smooth out properly and once it's dried properly I'll give it a bit of a smooth out ;)

Here's some progress shots:

Two things I felt were necessary for the road and guttering were a stormwater drain and a sewer manhole cover. More Inkscape and CNC work have facilitated some pieces I'm really pleased with:

Image Image

Painting the Warhound is coming along nicely. All of the blue is done (except the legs, which haven't been primed yet because I've been playing around with them sorting out the base and don't want to damage the paint in the process). I decided to have a go at doing a marbled effect on the blue armour plates by mixing a little white with the blue colour and spraying it on in wavy lines (with the airbrush set at a very low pressure), but it was a bit too light and contrasted too much. So I had to spray a thin coat of the base blue colour over the top to dull the marbling down a bit...

Image

I masked off the metallics that had already been done so that they didn't get tinted blue from overspray:

Here's a shot showing the pre-shading on the head armour plating. It's since been painted yellow, but I haven't grabbed a pic of it yet. The pre-shading works really well with light colour like yellow!

Image

I'm currently working on the brass banding and it is officially the most boring part of this entire project! It takes forever and requires two coats to get a good coverage (you can see what just one coat looks like on the torso armour plate).

Oh yeah I can make that....
