Ancient monument laser-cut and engraved from solid Ash wood.

This small scale, stylised architectural model was commissioned as part of a test project for a new educational play scheme for young children. The client wanted a simplified representation of this ancient monument in a pale coloured wood so we suggested laser cutting and engraving out of solid ash would be a suitable option. The main photo shows the 800mm long model photoshopped into a desert setting which is the context it will be used in. The smaller photos show the two sides of the model and a close up detail.

Educational models for two different clients.

We’ve produced a few house section models, or what might be termed “dolls house” models, over the last few years but they don’t come up very often so it was quite a coincidence when two unrelated clients ordered these very similar models within a few weeks of each other towards the end of last year. Both models were to be used as educational aids; one for a London based university and the other for a South coast county council. We delivered the models earlier this month and both clients were delighted with the finished results.

Fourth model this year for national developer.

One of the UK’s largest housing developers has come back to us again for a 4th sales model this year. They’ve been coming to us for many years for their sales models because of the consistent high quality and value we deliver every time. This model was particularly challenging because of the steep topography of the site which meant that virtually every plot was on a different level. As a sales tool it was important that we accurately modelled every step, retaining wall and embankment across the site so that purchasers could easily understand the levels and contours around whichever house they were looking to buy.

2.5m high models of Communications Masts.

We recently completed this pair of 2.5m high models of ships communications masts for use at DSEI, the premier UK defence Industry event. The masts, one for Port side, one for Starboard, were designed in sections that could be packed into a flight case for shipping and then be easily assembled at the venue. The design also included an extendable aluminium tube to give added strength to the masts’ main structural core. The main photo above shows the models on stand at this year’s event.

Third project this year for South of England developer.

As with the previous post, this is one of three sales models we’ve produced this year for another of our regular clients who keep coming back to us for high quality sales models for their marketing suites. This model was at 1:150 scale which is the ideal scale option for smaller housing developments. Larger developments typically need to be at 1:200 scale or even 1:250 scale just to keep the model base to a manageable size. We were planning to post photos of all three projects this month but two of the almost completed models have gone on hold at the last minute due to some late design changes on site. It’s probably going to be a couple of months before the other two models can be fully completed but hopefully we’ll be able to post finished pics towards the end of this year.

River Bed Model in Fibreglass – Horizontal Scale 1:125,000, Vertical Scale 1:125

Commissioned by Cardiff University’s Engineering Department, this 6 metre x 4 metre fibreglass model of the River Severn Estuary and Bristol Channel river beds was a very technically demanding job, not just because of the huge volume of complex data involved but also because of the sheer size of the project. Comprising several large sections that bolted together, it had to be an accurate representation of the riverbed contours (at an exaggerated vertical scale) because it was being used for physical experimentation in a major research program on tidal power generation.

 

How we made it

The first stage was to create a “mirrored” negative (upside down and back to front) version of the river bed contours all the way from Gloucester, down the Bristol Channel as far as the open sea. This comprised six major sections and several smaller, infill sections. These contours were made from laser cut acrylic layers supported on an MDF substructure, all fixed onto a structural base board with upstanding sidewalls. To construct the accurate depths and contours we had to create our own CAD masterplan using a combination of traditional Admiralty Charts, CAD contour maps, reams of numbers giving spot depths, and numerous sections through the river bed at key areas.

Once the basic structures of the moulds were built, the contours then had to be blended into a smooth continuous “land-form” using various filling techniques. At the same time great care had to be taken to ensure the contours matched perfectly across the joins between the sections. The contours then had to be sealed and “polished” to a fine finish so that the fiberglass forms would come away cleanly from the moulds once they had cured.

The final stage was to layer up resin and fiberglass matting into the moulds, starting with the “gelcoat” layer (which is in effect the top layer and is the visible finished colour) and then several more layers of resin and matting to build up the structural integrity. The fibreglass sections were then eased out of the moulds and flipped the right way up, ready to be joined together on to a structural sub-frame which supported them all at the right height. The image shows the sections just after they have come out of the moulds. They had been loosely assembled on the floor to check for fit.
