Hey folks...!


As you may have noticed from the first couple of pictures, we've managed to get a little further on...



We had already cut out the basic shape of the "esses", and matched up the join on the back straight. I screwed that down to the riser and started playing around with bits of spare decking planks to form the gradient supports. The picture above shows the last 6ft or so of the back straight and as you can see, 3/4in MDF really does flex a substantial amount... Takes quite a bit of force though; thank God for mechanical leverage! :oD



Next (and last sheet) to be done was the 8'x4' which would hold the rest of the start/finish straight and the first corner. Turn 1 is a compound corner which tightens up as you pass the 90* mark. After cutting out a section so that the leading edge of the climb would sit flush nd routing Turn 1, we slid the sheet under. Then it was simply a case of joining the dots to complete the straight. As everything seemed to line up, we secured that sheet too.


Crude but effective decking planks form a very solid support, and the above photo illustrates the slightly shallower grade up to the back straight.

Next up, we'll be filling any screw heads sitting slightly below flush with the track surface. We'll also be sinking some brass screws down through the track, for power feeds from underneath the track to the copper tape.

Ciao for now!
