Designing For Laser Cutting

[Rob Pulham]

There are some plain 7mm samples in with your bits I think I now have two viable methods of making brickwork each with its own advantages.

I forgot to say the samples arrived yesterday and very tasty they are too - I need to re-read this and other threads to have a go at finishing them.

Looks well guv, but you've forgotten the scuffs and cracked brickwork where the double deckers and high trucks have hit the low bits.

I hope double deckers werent going under the arches

If they did then they came out as tourist open tops on the other side

Cynric, they look good.

Hi Guv,

the width between faces of an arch to take double track, needs to be 185mm at 'waist' height of a coach (107mm say 110mm for a single track) , and the height to the soffit from the centreline of each track needs to be 105mm (min) overall height of the 'panel' should be around 140mm including the coping stone.

Hop that this helps.

cheers

Ok this is just sketching a 'scenic backdrop', the arch will be filled with either brick or a little industry, the origin is a generic arch combined from shots on Google.

 

[Rob Pulham]

That's just the sort of thing I had in mind for my diarama

Version number6......




this is 1/32 and the difference is very noticeable, the bricks are more rounded and generally less regular. The downside is the increased preparation and longer cutting time.

I am not sure that engineering brick as used for railway buildings has degraded to the extent of recent pieces. Maybe there is a need to photograph the walls of an engine shed / station building for reference?

Didcot anyone?

It very much depends on what the prototype is, I would agree that blue brick would have worn pretty well, but using Wallingford as a reference point, the shed was quite tatty by closure and the station building had quite a few spalled bricks. The parcels office was better as it was just 25 years old, but the beauty is that I can 'tune' the brickwork. The really clean brickwork scales down very well for 7mm, but it is not quite right for 1/32 or 1/35

Guv'
Just looking at the shots of version 6 and just as they are the wall with the window in has the appearance of what I call "soft yellows", there were reds as well ( my house is full of them), while the other sample if tinted a little could pass for "flettons"

I have got back to the Parcels office drawing and completed a little tidying looking at the shots I still need to do the window ledges, but otherwise the final shape is good to go
The battens have been ommited as the brass sub roof will sit in that space, forming a removable unit with the aluminium corrugations.

The learning curve has been huge doing this and the design process has been refined although it still uses 4 applications

Very impressive Cynric

 

[28ten]

In between everything else a little work on the arches..


I have an orders for 40ft of the stuff in 4mm

 

[Ressaldar]

so my 16' in 7mm will be a doddle then please let me know when it might be coming off of the production line.

cheers

It sounds like my 2'6" will be mere offcuts then - but still they will do the job.

First test cut, like a right noob I forgot to explode the polar array so the arch didnt cut
Standard clean brick is the most appropriate for the engineering brick especially in 7mm



the lockups will be mix and match with several variations

I like it! That brickwork could just do the job for us Cynric
