Re: GER (Norfolk) single arch under bridge
Tim the windows look really good, the lintels I am not so sure about as they should go into the brickwork if they were concrete. the metal frames windows make me think of a project I was looking at a couple of years ago. All the metal frames were to be reglazed BUT the mastic/ glazing putty had asbestos in it to hold it together. It was going to cost a bomb to get the asbestos out of the 5 story building! I must have got the tender right at we missed it but came second but 300K... I have heard the company that did win it, realised part way through and tried to recover the loss through variations and any other means they could come up with... then ran over time but 6months. But back to modelling... all very convincing. Tim I think you will be onto a winner with all these Laser cut/etched buildings no doubt other people will be asking for one of your kits!

The lintels should overlap the supporting bricks by 6" each side

Re: GER (Norfolk) single arch under bridge
Thanks Lindsay, Doug and John,
The lintels, although look odd, are correct. I'm living on a housing estate which uses similar lintels, but I must confess to not really knowing how they actually support the brickwork above without resting on the windows! I suppose they must key into the inner brickwork at some point.
Lindsay, the laser (tube) heats up during the cutting process. I do have a cooling system but this seems to set itself to the ambient temperature of the room im in. As the laser heats up, the cut becomes weaker. At the size i'm trying to cut, any small adjustments makes the difference of the windows either fitting or looking a bit naff. I must look into getting a cooling machine which I can set the temperature at and keep all the laser settings standard.
On the planned to do list, I've a local station, and a couple of signal boxes I'd love to try. At the moment though, I've got a couple of commisions on the go, which will end up being kits as well.
And measured up on Sunday . .
Cheers
Tim

I don't know how you find the time to prepare the drawings for the laser cutter, have you managed to automate drawing bricks for example and what sort of money do things like a laser cutter and a 3D drawing thingummy cost?

Re: GER (Norfolk) single arch under bridge
Tim I find the plate layer hut interesting as it has a new corrigated roof on top of the existing. Like a lot of bituminous roofs they break down over time. They are a bit harder to replace and the leaks are harder to find and fix. So a full replacement is always the answer. It will be interesting to see how the laser cutter goes with the precast building style. I like the look of the county school station.

Just goes to show, we should always model what we actually see and not what we think we know.

Re: GER (Norfolk) single arch under bridge
Absolutely Jim,
John, I suppose half the time is drawing them up. I kinda know what I'm doing now, so when I draw it all out, it should all fit together. The only automated thing is the corner brickwork which interlocks. These I just copy and paste into each course at the end of the walls. Everything else is done by hand/mouse. It can be repetitive, but most of the buildings I've done have got some non standard brick sizes in them. This is what takes up the time, it's just observation but essential.
A laser cutter can be purchased for around £1500 for a small one, and similar prices for a 3d printer.
Doug, I would say that the corrugated roof is fairly new. It's now in the hands of the Mid Norfolk railway so I'd guess they have put the top on over the old concrete roof. I'm looking forward to getting on this one as well.
I've also had a quick go at doing an open window pack. Quite fiddly to glue up, but they seem to have come out ok.
Cheers

Tim, I love the long-exposure shot of Spooner Row. I know the Great Eastern was renowned for its eccentricities but a signal showing simultaneous clear and danger aspects really has to be unique......

The large double window in the middle of the County School building looks interesting. I wonder if it is a later addition, perhaps even done in preservation times? There can sometimes be a problem in measuring and taking pictures of buildings (or anything else) as they exist now and then making a model of the same which is set at some time in the past since things may have changed. On the Pulborough station building, which i made, there is a window which was there when we did the research in 1985, and still is, but it was not there in 1912!

Learning CAD packages always takes time, but like most things the more that you do, the quicker you get. You just have to be prepared to put in the time.

I was trying to use a free CAD package yesterday but got nowhere with it. It seems I have forgotten all I used to know about AutoCAD and GenericCAD, the latter package being the one I used at work for several years. The free package is called LibreCAD which is attempting to be similar to AutoCAD but is still a 'work in progress'.
I then found that QCAD is now free for personal use and LibreCAD is based on that package so installed QCAD as it has online help which LibreCAD doesn't have as yet. QCAD is available for Windows and Mac as well as Linux so worth installing for anyone wanting to have a play with CAD.
I have decided that as all I want to do is draw up details of the Toller bridge, mainly a cross-section and location of all the tee & angle sections for modelling purposes it will be easier to use pencil and paper. Now I need a drawing board and tee-square, which of course are things I used to have once upon a time!!!

Re: GER (Norfolk) single arch under bridge
I once asked an architect whether the use of CAD had speeded up the design process. He said that the opposite was true - it took longer to design a building on a CAD system than it did on the drawing board.
The CAD system, however, came into its own when you needed to copy drawings (no more tracing or redrawing) and when you wanted to overlay, say, services as a separate layer - again no re-drawing.
So CAD really comes into its own if you are preparing a complex design for techncial assessment (planning applications, building regs, etc.) and for the production of various contract drawings, production of sub-assemblies, etc. etc.
But is it what you really need for a one-off hand-built model? Or is this a case of the tail wagging the dog?
It's surprising what you can design on the back of an envelope with a blunt pencil. Further sophistication can be introduced by the addition of a cheap plastic ruler (but drawing it free-hand is more fun).

The primary use for my work based use of a CAD package was for floor layouts in a seven storey office building, Once I had the outline of a floor set up in GenericCAD and had created a library of furniture it was easy to add furniture to a floor, move it around, switch between floors and so on. I used layers for services like telephone or computer cabling and so on.
That CAD package once set up made it simpler than having to do the same thing on the drawing board I started off with.

I did try the Dassault Systemes one some time ago then found that LibreCad was in the Debian repository so simple to install and it automatically ends up in the Gnome Menu. So it has resided in my system for several years without me making any serious attempt to use it. QCad is closer to what I remember AutoCad worked like but that was a long time ago, possibly version 9 running on MSDOS, I still have a copy of "Inside AutoCad" published in 1988 and bought when we were on holiday in Toronto.
The copy of AutoCAD I had been given was a hacked version and didn't need a dongle so I could play with it at no cost. Nowadays I don't need to use pirated software as Linux provides 'good enough' software for almost every need.

Re: GER (Norfolk) single arch under bridge
I've spent a bit of time yesterday pulling apart the rest of the goods shed drawing. Not happy with a number of areas, but at least it all goes together and is square
I've also managed to get the internal walls and roof done on the Mess Hut for Eastleigh, I'll try and get the doors and windows completed today.
Terry, you are correct. County School station has had a number of changes over the years. It's easy to get caught out with changes and additions. One good example is my home village station; at first glance you would think that nothing has changed. When you start to look, you can see that the previous BR station was a single storey flat roof, someone added a second floor in the 1980's

Re: GER (Norfolk) single arch under bridge
I've finished the prototype for the Mess hut at Eastleigh Depot for a customer, It's come out well. Need to tidy and adjust the cutting drawings a bit for a finer finish but overall I'm quite pleased with this one.
I will also be attending Scaleforum on the Saturday only, demonstrating my lasercut buildings and drawings. I'll be on the DEMU stand with some other fine modellers and demoers. Come and say hello and have a chat if you want

Re: GER (Norfolk) single arch under bridge
One really good reason for using the laser cutter to produce the brickwork buildings and components, is that once drawn, you can scale stuff up and down. You still need to make fine adjustments though to each set of drawings, but the hard work is done.
Apologies for not sticking with 4mm, but I know that others on here model to different scales as well
A trio of scales, 2mm, 4mm and 7mm from the same drawing:

7mm:

Re: GER (Norfolk) single arch under bridge
Just doing some testing today, I wanted to get on with the original bridge at the start of this topic. I thought I'd start with some simple under arch brickwork on the Tring cutting bridge before I move on to the skewed bridges
I've been messing about all afternoon trying to crack the method I'll use for creating the brickwork for under the arches. Apart from the layers being quite fragile, I think it will work quite nicely. I should be able to get the tooth effect I've been after ever since I started the GER bridge too. Just needs some careful measuring and drawing in Trubocad until it's correct. Apologies for the quality, I've messed and tested stuff on it so much this afternoon I've broken a few bricks!
Just another test, someone put a photo of a nice little brick barn air vent on my facebook page, and I couldn't resist copying it
And another finished (almost) model of a tiny power box that sits in Tring car park. I need to do a bit of Jim's handiwork and put a scale padlock and bolt on it though
Cheers

Re: GER (Norfolk) single arch under bridge
Some progress pics on Mike C's little lamp hut building, sorting out the floor and interior walls.
I've lasercut both sides of 1.5mm (ish) mdf to achieve the brickwork look.
I've also taken on board what Dave McWilliams and Brian Hanson have mentioned about recessing the windows from the back. It looks good for this building, just need to do some more fine tuning and it should be ok.
Yet another one on the go (please stop me if you get bored!) Spooner Row signal box, on the Breckland line, box now closed
Onto a personal project. The aim for Tring is to copy the exact track plan as close as possible. Knowing that I can cover most baseboard aspects by laser cutting, I've started to think about how to relate the drawings for each of the OHLE masts which give a detailed description of track spacing and cant.
I had a quick play with using the drawings to draw out a laser cut track profile. This idea seems to work very well, I just need to now decide the best way to include the drawings into the baseboards design.
Cheers

One bridge which caught my eye and has nearly been completed is one near Waltham on the Wolds. It goes over an old mineral line, and I loved the shape of it. Spent an hour measuring it up on the way to a friend and have managed to capture the look of it I think . . .

Re: GER (Norfolk) single arch under bridge
Those platform edgeing bricks are simply amazing. You should market them. I womder though looking at some of the other brickwork if you might be overcutting, the sawtooth effect kn the wall ends looks good but in many of the pictures it looks like it might match better if the cutting depth was reduced, what power are you cutting at !
been trying to convince the domestic godess that I should get a cutter, she has not said no, but then again she has not said yes either....
I follow with interest.

Re the Tring platform wall, and the diamond-paved platform edging - Cor!!!!
Can we have more details, please? These items look amazing.
Is the surface of the bricks and the diamond-pattern incision of the paviors all reproduced by laser-cutting? This detail really is impressive.
