OK here we go. My Goodwood Track thread.
I have some of the sections started, most finished and some of the sections still to go. Mostly due to the fact the I am learning more and more about the Goodwood circuit and how its driven. I keep changing my mind but I'm nearly decided on the final shape. I've watched countless hours of in car footage of drivers negotiating the final couple of corners from Lavant through the Woodcote corner and down to the chicane and I find they drive these corners pretty much as one giant right hand turn so I just made it so you'll have to balance the car at speed in a giant slide. I started making the track corners exactly like the aerial photo of the track but found it was a bit too slot car-ish and the cars would pendulam on the guide maybe a bit too much. Also, as you can see from the following photos, the track is 4 lanes and this final section is one giant squeeze. This is mainly due to the fact that my boys grow and get faster and faster/ there'll be little chance to pull alongside and pass as I guess they'll just pound around this track pretty much on the limit. Although the squeeze section is just wide enough to fit past..just! So perhaps make the corners through here work best suited to the slot cars and get used to the fact that I wont win many races around here anymore. So here are the first couple of photos and I look forward to everyones comments..enjoy.

well, another masterpiece on its way.

good luck with it, and I'll be looking forward for updates.

Cheers

I second what everyone else said,

Specifically a track plan for this track, and more info on the one in the background

Very nice..lets see some photos of the track in the background. I take it, like me, you like the old fashioned cars. I`ve just received the Cartrix Bugatti T251 today, and like the other Cartrix clasics it`s a beauty..would look great on your Goodwood...keep the pictures coming...

I dont really have a track plan. I just google earthed the track and then worked out how the track boards would lay out from there.

The Brooklands idea was ok and the boards I routed worked easily but you drive around almost flat out so that mean't classic cars in huge accidents. Still fun to try.

The Goodwood idea seems to me to be the most practical. The square flat layout will lend itself to some fairly large radius corners and the racing will be alot cleaner and easier to learn for the novices as the corners can be made with plenty of room between lanes. So no track plan as such but I've built enough layouts to know what looks good on paper might be a bugger to get a slot car to go over.

Next is to work out how to hoist the whole thing to the ceiling on a frame.

More work done today on the frame for the track.

Image


Basically, its the same stuff we use to make metal frames for internal partition walls. Extremely light and very strong. Hopefully not too many issues hanging it all up from the perlins. Then it was a matter of putting the main chicane straight and start straight onto the frame and then aim the whole set up for a spot where I think the Lavant corner will exit when the cars leave it 12.5 metres away and then head up to this section. Its pretty much the only spot it will fit and its very close to the right shape so I can count myself lucky that the shape is ok..

Image


I also re-shaped the Chicane ..

Image


I thought its now a bit closer to the historically correct shape. The Goodwood Chicane is such a significant section of Motor racing track I thought it best to get it right. I can always make Madgewick, Fordwater and St Mary's absorb any extra curves to bring it all back into shape.
I also mean't to say , when I mentioned I didn't use a track plan I have plotted the whole thing out to within a few degrees using the satillite photo. So although I dont consider myself a rivet counter, if this track didn't closely resemble Goodwood, it would drive me mad.

So on with the show..

Heres a wide shot.

Maybe a bit hard to see. Track is hanging off battens in the shed. Perhaps a pre-disaster shot. Lets hope not. It's not heavy so I just hung it off small hooks and some light gauge chain. I should park the new car under it. Then Murphy's law says it will fall down instantly. Or give me an instant "hillclimb".

Image


This means I can now begin to put together the run through St Marys down to Lavant before placement of the Lavant Woodcote run.

Nope no rain. Its the middle of Rep footy so I'm all over the country with my kids at the moment. Costs about $3500 each trip. ( God I wish they played the piano) so cant justify extra money for slot cars just now.

I've completed the frame work for the roadway down to Lavant and including the bend at St Marys. Its all raised up and looking good for weight and I hope structurally safe as I have our 4 cars parked under it. ( lets hope it stays up there or Yikes am I in trouble if....)

Only the run back to Woodcote to finish, lay in the boards and we're good to set up a lane and trial run it.

Cant believe its been six months since I started this track. A few problems occurred with the original design. One problem was the space around the outside which forced us to push the track against one side of the shed. My boys and myself managed to get away proper at race start, but every other "expert" slot racer seemed to be constantly having an off exiting Madgwick and end up in no mans land on the run down to Fordwater. This part of the circuit was quite hard to access given the position of the track in the shed and my pursuit of the longest Goodwood circuit possible making me reluctant to throw up the white flag for a 6.5 metre main straight and reduce it to 6 metres. Thus, to retrieve your car you had to walk the track backwards starting at Woodcote, down the 8.5m Lavant straight past St Mary's and then 10.5m back to about halfway between Fordwater and Madgwick.

So scenery was put on hold as we began to redo. I really need this to be a circuit that anyone can drive well on, I hope. So I figure rip it out and start again so all track sections into the skip bin, go from 4 to a potential 5th lane for a pace car which peels off as we enter the main straight. ( Can you imagine the temptation to nerf the pace car from Master 6yr old ) I can also potentially use this lane much the same as the 3rd lane on the little track which gives me two very marginal overtaking spots but you have to be patient. So no 'squeeze' sections apart from the chicane itself and perhaps a bit more anger into St Mary's which turned our to be a little easier drive fast into than I wanted. Perhaps you could argue to leave it like it is because no carnage and all cars pretty much in one piece.

Also redid the structure itself while the opportunity presented itself and put in a little bit more stiffening. Still very light given its size....

Hopefully some fine weather tomorrow so I can cut the MDF board outside. Really getting some rain here at the moment.
