So this is the bridge I am trying to recreate.  Little Petherick Creek bridge near Padstow.

Made a trip there over Easter and got a lot of detailed pictures

Found out a lot. Seems like the square sections at the top of the pillars are hollow...I have designed them as solid granite or concrete pads.

Oh well, my bridge is "inspired by" rather than an exact copy!

And so the 3d printer has been working overtime. 

The main girders are 466mm long so clearly far too long for the printer.  I have split them into three sections for printing.  

For the outer ends, I uploaded one end to the printer then just flipped it mirror image to make to other end. My sharp eyed daughter spotted that the 2024 little date plaque also got mirrored so I have some mirror text. Luckily it's all too small to see really.

Here are one set of girders ready to be joined together.

And here is my version set up on the dining room table.

Just what dining tables are meant for!  No curve to your bridge then.

 

That's mighty impressive Ian, so pleased I was able to assist a little.

That is a most impressive homage to the original, which we are lucky to be able to still enjoy, albeit sadly without rails. I travelled across by train in the early '60s, and by (hired) bike in 1997.

Hi Peter, there will be a very gentle curve but not as much as the original!

Excellent! Looking forward to seeing it in position. I’ve walked across the real thing but I don’t care to remember how long ago!

Hi,

 

That looks fantastic - it really has presence - even just stood on the table.

 

Great job.

 

Regards,

james

Today is the day the new bridge goes in. First thing..rip up the track. 

I don't like doing this!

So the big guns now bought in.  Ah spans now levelled in and positioned.

Time to break out the glue and go for it.

It's up and running again

A long day but we now have a bridge in place and track reconnected and working.

Finishing off to do.

By which I mean:

Upper braces

Pipeline across the bridge 

Access hatches

Painting and weathering

I've done the access hatches but not much else.  We have our railway club meeting here tonight so the new bridge will get a bit of use!

So now I have to complete the area under the bridge. I want sandbanks and low water channels, seaweed, rocks etc. I need to transform this:

To this:

Any hints on how to go about this? I have fine sand and resin to hand.
