The shuttering in place and the concrete pads poured:

How do you manage to do this Trevor? It seems to be perpetually raining here in in Carmarthen, not that far away!

I think I grab the moments between the rain drops!

No seriously we have had some dry spells between the showers.

Ooooh, I do enjoy seeing civil engineering like this in progress - keep the updates coming!

As Columbo would say, "nice place you've got there".

I love the epic scale you're working on there - it should really work for the Welsh slate vibe. I can only imagine the mountains in my bit of "Wales" (a small Bristol back garden), but you're going to be able to do it properly!

Thanks for the updates, much appreciated...

Andrew.

I have made a bit more progress. Lots of other things going on here which get in the way. It is beginning to take shape, with the trackbed following the lie of the ground - which seems quite satisfying:

The vertical difference beeen the two ends of the trackbed is now 12 inches. At a slope of 1 in 60 that means another 60 feet of trackbed needed. I have 2 more gravel boards to lay, so that is 12 feet, leaving 48 to plan for. That could be a circle of just over 15 feet diameter, so we are within striking distance.

Looking wonderful Trevor, but with only two gravel boards left you might have a short intermission during lockdown as deliveries will surely be affected.

I don't think that the lockdown is going to make much difference really. When I have those last gravel boards down I was going to change tactic anyway. My thoughts were that on the rising part I would start the curve outwards- over the void if you like. After a 1/4 circle I thought I would then reverse the curve (dangerous for good running I know) and start 3/4 of a curve to join up with the other part.

Somewhere in this I want a run round loop, which means doubling the width of the trackbed for that.

So all of the curved bits I was going to cast in situ. Gravel boards and sweeping curves just don't go together!

However I have bags of gravel, sand and piles of rock which are in the way. I think I have to finish the path along the first extension to use that up before I can continue with the trackbed.

So for the first lockdown I dug out the bank. It seems appropriate to use the second to finish off the area I dug out.
