Riveting stuff

Rivet detail for the Crossdale Tunnel bridge #4

The Crossdale tunnel bridge is looking good as a structure, but has none of the distinctive surface texture of the prototype. To remedy this I have laser engraved some riveted panels onto 400gsm white card. The results in the pic above really stand out in the strong afternoon sunlight.

Half way there

Half of Crossdale Tunnel bridge assembled

Assembling the Crossdale Tunnel bridge #4

Well that’s the first half of Crossdale Tunnel bridge assembled and no, I’m not ‘living on a prayer’. Now I’ve ironed out the wrinkles it’s on to the second half. I’ve just got to laser cut another set of parts.

For the railings on the sides of the bridge I have used two materials. Firstly, I have laser cut a framework of 1mm MDF to support the decorative ironwork. Secondly, the lattice railings are laser cut from thin card. Again, these are a simplification of the real thing but, hopefully, will capture the character of the bridge.

On to the next stage of the Crossdale Tunnel bridge kit. This is to add the small vertical ribs between the cross braces. These are very thin parts which are notched to fit into slots on the sides. They are a bit fiddly to glue in place and take a little patience. I broke two pieces in the process (Grrr!), but I had cut more than I needed anyway (Yay!).

The ribs are a simplification of the real thing but look the part when assembled.

I do love designing for the laser cutter. This time it’s the Crossdale Tunnel bridge. The material for the kit is 1mm thick MDF.

With the components designed and cut I’ve started putting it together. All the parts are a good fit and easily glued with PVA. Beginning to look like the Ambergate bridge already. Although this is only half of the final span.

Just waiting for glue to dry again. Grrrr.

Where the ‘Crossdale Tunnel’ breaks out of the cliff face, I have now glued the laser engraved tunnel portal, which I laminated together back in September. It just needs a bit of touching up and some texture adding now.

Clad all over #2

I have started gluing the laser etched stone detail to the first viaduct abutment. Other low relief details are then added, etched onto a thicker card. I will add the texture to the stonework at the next stage.
