Yesterday, I promised a picture of the cut upper level, well here it is:

It was quite an effort to make sure whole lot didn't break and it's time like that you wish you had a properly equipped workshop with a nice big bench.

The advantages of doing it all as one piece is that you the wood helps to make the transition smooth. Of course there might be some issues at the bottom but they can be overcome.

Next I will be laying a cork strip along central track formation, then the whole lot will be painted grey before supports are put under the board. I'll be screwing the ends of the ramps to baseboard.

Lots of the offcuts will be used to provide the pillars, plenty of PVA will be required!

Now does anyone know of a electronic spirit level? I'd like to be able to place it on the ramp to measure the angles accurately to make sure I have a consistent gradient.
