Some progress at long last
Some decent weather and a back that can cope with a little bit more work has seen the first bits of the running surface attached to the timber frame.
A central anchor point was created using wood off cuts to make sure I could keep a constant radius when using a guide to position each plank around the end curves. The guide is just another piece of timber with an offcut of ply screwed to the end.
I forgot to take a photo of it in use, but mocked up here you can see how it locates each plank. Another spacer is used to create the gap to the adjacent plank meaning there is no measuring to be done.
And the end result is the first part of the curve from the lift out section to where the point will be.
It isn't much as I could only manage a couple of hours, but having worked out the spacing, tools and got everything collected together, I'm hoping for slow and steady progress in the evenings.
