40 foot Bailey bridge

 

Being an ex Royal Engineer in the 60-70’s and built these beasts for real it was only fitting I should make one. I found some files in the web for a 1:100 scale bridge. That was the staring point each file way re-drawn to 1:76 scale by 131.57%.

The components parts were merged in the 3d print slicer to form one side of the bridge. Both sides were assembled in a card jig to make sure the transoms aligned correctly. 5 stringers were fitted to each bay 30 in total.

I use EMA plastic weld to join my PLA printed parts. The chesses are actually printed as a block of 13 I felt this would give the structure one strength.

Moving on

It’s been a while since my last blog post — life’s been busy with a mix of projects and a couple of brilliant holidays to Norway! Back on 22 March 2025, I treated myself to a Bambu Lab A1 Mini 3D printer and promptly fell down the rabbit hole of learning CAD.

3D printing has opened up a whole new world for my modelling. I’ve been churning out wheelie bins, station waste bins, skips — you name it. By spring 2026, though, I’d definitely outgrown the little A1 Mini, so on 25 June 2026 I upgraded to the full Bambu Lab A1.

I have to say, 3D printing is seriously addictive. Once you start, it’s hard to stop!
