In 4mm there are etched brick edging from Mike Clark, I'm not aware what there could be in 7mm.

 

Thanks Tim, I've had a quick look online to see if I can find anything suitable in 7 mm but to no avail so far. I'll keep looking but I'll probably have to scratch build some:-)

I saw those pictures of Dyffryn Ardudwy too. They are the ones I saw in the photo of Towyn too. In both cases they were along one platform only. Usefully one of the photos has some modern bricks nearby. These look larger than a normal brick it would be better to make any casting to cover several as it would be fiddly laying them individually.

At one time the station building was up for sale. Mrs W was not persuaded to move there. Now if we had known of the lovely walks through the woods it might have been a better bet.

Hi Don, yes I agree the edging does look bigger than a standard brick. I'd probably make a casting so that it covered about half a dozen bricks. As my platform is on a gentle curve any longer than that when they are laid the platform edge might end up looking like an old thrupenny bit!:-)

 

What a shame you couldn't persuade Mrs W to move into the station building, it would have been a lovely place to live and you could have popped out and measured the pavers for me:-)

Dave,

I've just looked in my old copy of "Great Western Way" (1978 version), and under the platform surfaces section gives the size of the blue diamond pattern bricks as 1'4"x5" with a bull nose radius of about 2" at the end for platform edging.  Similar bricks for the platform surface (without the bull nose) are given as 10"x5".

 

I knew I had seen the sizes somewhere, and finally remembered where!!  (Oh to be young again) :-)

Thanks Ian, that's brilliant!) They were obviously bigger than standard bricks, but by exactly how much was proving tricky to find out!

 

I know just what you mean about being young again:-) I've wasted hours of modelling time searching for articles that I know I've got somewhere!

 

Thanks again for the information, I can feel some experimentation in production methods coming on :-)

I wonder if this is the kind of thing that would be best tackled using CADCAM? Each edging tile works out at about 10mm x 3mm in 7mm scale, so the diamond pattern needs to be very fine and precisely positioned. I'm not sure any jig that I could cobble together would have the necessary finesse and accuracy!

 

Computer aided design is not some thing I know much about, maybe a question in the relevant part of the forum would point me in the right direction.

 

If anyone's got any thoughts on the best way to proceed I'd love to hear from them!

I suspect the most effective method would be to drawn it up in a cad program get a sample or two 3d printed. Then use them to make a mould to resin cast them.

However I have no idea how you actually do that. Rich Brummit who posts things on RMweb is involved professionally in rapid prototyping and I has used these techniques for modelling. There may be a 3d printing thread on here somewhere.

Hi Don,

 

It sounds like we are both in the dark when it comes to cadcam! I'm going to have a read in the CADCAM section of the forum and see if I can get any pointers.
