Repairing the trestle

[gregh]

Last week I decided I needed to lop a few branches off a tree above my big timber trestle on the sandstone rocks. All went well until one branch bounced off the ground and hit one of the piles and broke it it.
I have been playing around with a tower crane I bought from Aldi. I had removed the 'tower' and mounted it on a rail wagon, so I thought I'd use it to make a video of the repairs.

Great idea, Greg. I've seen a few photos showing repairs on garden railways but not seen a video before. The movement on the crane is very smooth, I assume that's not stop motion animation??

Thanks Rik.
The segments with the crane raising/lower the hook and rotating are 'real' videos. I did speed them up by x1.5, as the crane is pretty slow. I have yet to master stop-motion.

There's a bit of stop-motion in your video - when the repair train moves to a new position.

I tried some stop-motion animation a few years back when I did an animated map of my railway (Blimey, just seen it was over 6 years ago!). I stitched together hundreds of images generated in a Draw package. I found a freebie program to do the stitching into a video. Took ages but I was reasonably happy with the outcome.

Great job Gregh.

I thought I'd watched all your videos, but I don't remember that one. Sure must have taken a lot of work.
Still not what I consider as 'stop-action'. Maybe I have the wrong terminology. Mine is just a few stills strung together. I'd like to be able to do something like those speeded-up construction videos you see. Like this bridge built near my place...

What was the actual time frame Greg?interesting video,thanks for posting

Getting off topic, but it seemed to take years to build. Lots of that time was probably spent on the piers. The actual deck launching still probably took a year (from my hopeless memory.) Here's some more info.

Thanks for that extra information,for me very interesting as in a previous life I used to be a steel fixer and worked on a few bridges amongst other things,happy days,enjoyed it,thanks again,Getting back to the thread its a shame that the crane does`nt bend in the middle,I`m assuming that the 360% gearing is "solid" that will not allow the model to follow a curve but as you say will make a good static model,are you keeping it on the flat car or in a lineside position?

You're correct - because of the solid gearing, the crane can't follow the curves. That's why I had to try the 'stop action' of taking a pic, moving the train and jib, (usually resulting in a derailment) another pic, etc And after 3 or 4 moves I got sick of it!
It will stay on the rail wagon at present (usually on a shelf).

Greg, if I was watching the bridge building, the real one, with my eyes open and read the description you linked correctly, it looks like they slid the roadway onto the piers, having put it together on the opposite side of the valley.

Yes Dan, that's the way they do it.
Here is another similar build.

How did you manage to pick the next bridge up the road from my place???
I love bridges. Maybe we need a new topic on 'my favourite bridges' ?

Pure skill Greg or luck. One or the other!
