(12/9/2010 I've added some updates down the page, more pics and some details, Holty)

Having seen the plastic bits of my track buckle again in the heat I decided to go all wood. I decided to use up the surplus timber from old doors and some ply I had in the shed.

I used a nailed down garden hose as my router guide, so there are no constant radius curves.
Posted Image

Kerfing under the ply should allow a 'dipper' like drop in the esses.
Posted Image

The veneer on the doors is not thick enough so I glued 2 layers together to get sufficient depth for the router. The gaps will allow this straight to bend and have a 'Nurburgring' hump.
Posted Image
Any uneven or loose bits will get pineed by screws during the installation.

The painted hillclimb, with free-form curves like a real road.
Posted Image

The paint (for the technical minded) is some second hand Taubmans 'Japanese Lantern Shade,' $1 at our local recycling shop. It was the nearest to grey that I could find.

Overall I'll lose my tight Monaco hairpin and about 2 metres in length, but should have twisty bits that are little more kid friendly.
With a few scenery switches and swappable track direction I should be able to stage Bathurst or Nurburging enduros, or Targa Florio, Mille Miglia road races.

There are some kids visiting this weekend so I can't rip up the old track till next week. In the meantime I hope to get the paint, tape and wires ready.

An Update

After the last race session on the weekend, time to dismantle the old Monaco track.
Posted Image

Started assembling the new pieces in the Bathurst-esque shape.
Most of the tape is on, and the track has been wired and tested in sections.
Posted Image

Need to buy some more tape tomorrow and start testing elevation changes.

Gref, thanks for the tip.
The ply I'm using doesn't have a lot of flex, so I expect to have to screw down the ends and attach some sort of jack to the middle to pull it down. It only needs to be a small distance. My testing today with just a plain descent thru the esses was a 'trap for young players,' with the odd car stepping out. I don't want it too difficult for kids, so I might make the dipper adjustable so those who think they can drive can have a real challenge, and the rest can have an easier run.

Looking good holty. Very nice. So what is the size of the track, looks about the same size I am working with.
Thanks
Greg

The track is assembled and running with rough elevation chocks and simple mock scenery.
The table area is about 1.3m by 3.5m

The hill climb in the Mt Panorama direction with the cutting foreground and the esses with Forest's elbow in the distance. The Cascade bachground is just a temporary green forest backdrop.

The pit area with Suedkehre (South Curve) as per old Nurburgring
Posted Image

Also I have the humped straight of N-Ring or Conrod in the other direction.
Posted Image

Which is trying to emulate the hedged straight as per this photo from the F1-GP history site.
Posted Image

The Nurburgring clockwise direction is the trickier, the hairpin at the end of the long straight has caused me to roll many cars. Lucky I have the catchment fencing there.
The MJKs grip well to the painted ply, even the Ninco rubber on the classics goes well.
Thanks to soldered connections and all tape I have good power everywhere. I just can't stop driving on it.

An update

Some plaster and cardboard to start forming the Mt Panorama styled cutting and the esses.
Posted Image

I've painted some urethane foam to create the Nurburgring hedges. The cardboard backdrop is the ruined castle looking over the track.
Posted Image

The old styled GP cars have too much grip and just tip over. To fix this for now I have turned the MJK tyres around so the camber is the wrong way round. This allows a more forgiving slide of the rear in the corners. It does look ugly with the bubbly side out, but you cant see that at speed.
Posted Image

Some kids have had a go and manage to circulate easily, so one objective achieved. For serious racers trying to push is particularly challenging, so I've achieved the second objective.

And it is starting to look great.

I bought a DC-DC upconverter (Jaycar MP3463 $40) to run an old laptop off the battery. I have 2 x 12V batteries that are solar charged in the shed, 1 for the track and lights, the other for the computer. This means no more long lead to run the computer for race management.
The pit area and South curve with computer on the far side

A close up of the refuel lane, for Ultimate Racer refuelling, just pick up the car and put it on the sensor strip until the display shows full. It beats remembering which key to press.
Posted Image

The whole track with green forest theme

In a couple of weeks I'll run a 70's Bathurst in the clockwise direction to test fuel management.
