Moving logs in the rain...

This week the weather has helpfully delivered sunshine on the days I've been working and rain on my days off for work in the woods... So yesterday, despite the rain, I took the trailer to the woods and got on with moving some logs.

This needs doing to get the logs in a place that's dry and windy, and under a tarp, so that they can continue to dry out. I went down to Alex's wood, where I did some work last winter, and collected four trailer loads during the morning and early afternoon, getting a bit damp in the process. One rack had shorter logs, which neatly fitted into the trailer:

Here's one of the racks I was emptying. As you can see, it was a damp and shady spot, so the wood is a bit damp still - but it won't be burned for another year or two, so there's plenty of time for it to dry out.

For the first time (for an actual job, rather than testing it) I used the bridge that EWB students built in the woods back in March.

The log trolley also came in handy, moving logs from a rack deeper inside the wood to the trailer, as there's still some tree stumps that prevent me bringing it further inside the wood at present.

There's still some more logs to move, but after that coppicing can start! :-)

EWB Imperial - building a log bridge in the woods

Last weekend members of EWB UK from Imperial College London came down for what's become an annual camping trip to our woodland. As always, there was a project to get involved with - this time building a bridge over a stream that can support a vehicle! During previous visits they built a firewood shelter and a foot bridge, so this year was a step up in scale.

I made a timelapse video of most of the bridge building, it's about 7 mins long (it's in 1080p HD, so put it full-screen). Take a look, and then read the rest of the post to see the pictures and description.


Here's the full team that came down this year:

The bridge is needed to allow access to a new ride that I cut last winter. I saved some of the stems I'd cut to make parts of the bridge, and we felled a few others as required to complete it. The first steps were digging some foundations, which took quite a while:

and peeling the long logs that were going to be used as the main supports:

We put some chunky logs into ditches that had been dug on each side of the stream:

and then got the main supports in place, bolting them down later on:

In the centre of the stream we also drove in some stakes (see the timelapse video above), and I used the chainsaw to cut a notch in the top of them for the main supports to rest in:

On top of the main supports went some crossbeams (all of this was Sweet Chestnut, by the way), and again I cut some notches for them to sit in:

Then there was a lot of drilling and nailing...

Some of it by hand:

though we did have a solar panel and inverter on hand to recharge the electric drill:

Once that was finished, it was time to start making the ramps to lead on and off the bridge and also lay down some planks (the only bit of wood that was bought in for this):

The planks were also nailed down, and it was starting to look like it might be OK to drive on...

Of course, there's a signature on the side of the bridge:

We posed for a photo or two:

and then it was time to put it to the test...

There were some creaking noises, but it was rock solid!

A job well done - thanks to everyone who came from EWB Imperial to help with this!

Woodpeckers, Spring and Bridges

The woodland is looking amazing at the moment. The ground is green,

The buds are budding (including our fruit trees)

Flowers are ... flowering!

and the woodpecker is lovely. I spend ages watching this little fellow. Not easy to get decent photos because of all the twigs.

There are loads of pheasants around

and lots of butterflies.

Anyone know what this is?

While I was being quiet watching birds, Mike and some engineering students were being noisy, building a bridge in another part of the wood. More to come on this topic from Mike!

Working in a different woodland

This weekend I went over to visit our friends Rich and Penny and work in their woodland. We're actually doing a swap - Rich will be coming to help me put some solar PV panels on our roof in a couple of months - but it was also fun to go and see their wood and work in a different setting.

Part of their wood is a bit hillier than ours, and has more of a stream in it, enough to warrant a foot bridge (under construction):

and a bridge to drive over too:
P1080402

It was along the side of the stream we were working, using a tirfor winch to pull some large chestnut away from the stream as they were felled.

We had a nice spot for lunch each day, and it didn't even rain on us!

Under another tarp, I saw a nice shave horse Rich had made, and a lovely Hazel chair Penny had done as well:

We should be back in our own wood just for a day in the next week or two, to deal with those two big Sycamore near the neighbouring barn. We've actually just started burning the Sycamore from a year ago, having exhausted our 2-year seasoned supply. Next year I think we'll get right through the winter on 2-year old wood though.

Engineers Without Borders build us a bridge!

Last weekend a group of students and graduates from Engineers Without Borders (who I know through my work at the Ashden Awards) came and camped in our wood, the aim being to have a bit of fun, do some team-building and build a bridge. Being engineers, they didn't just bring a normal tent - they had a geodesic dome they'd built themselves!
Here it is with the cover off:
They did have a couple of more conventional tents as well:
Anyway, like any camping trip a lot of time was just doing stuff like cooking:
and trying out new tools:
So, the bridge.... Well, here's the original bridge (over in Sweep Wood), which could only take one person at a time, and you had to be pretty steady on your feet!
We built this bridge about 18 months ago, but never really did enough to make it very good.

The engineers got to work testing scale models for a new one, some of which did not exactly inspire confidence!
But not to worry, designs were adapted for the types of wood and tools available, and we all set off back to the stream. A couple of chestnut stems were selected to provide 5m straight logs, and I felled them with the chainsaw. The nice bit was I didn't have to carry them anywhere, as I had a whole team of willing engineers! :-) They were soon installed across the stream:
Then posts were driven into the ground to secure them:
Someone came up with the idea of using split pieces of chestnut to make rungs:
and by the end of the first day the bridge was in a state to walk on, although not finished. Also, unlike the old bridge, it could take more than one person at a time:
The next day saw a lot of drilling and nailing of the rungs:
and by that afternoon the bridge was done, with the added feature of hand rails at two different heights!
I ran over some of the rungs with the chainsaw to roughen the surface so it doesn't get slippery in the rain:
and then everything was done.

I'm told everyone had a great weekend, and I'd like to thank everyone who came, and EWB-UK, for all their hard work! Some people worked so hard they fell asleep at lunchtime. Or perhaps that was to do with beer round the campfire the night before?
