Re: Testing your car on a guided track,when racing on a lane track

I have my tuning board level but can not seem to get the cars to touch the side of the rail at the end of th 8 foot board. I get can get the cars to go left or right but the va...

Re: Testing your car on a guided track,when racing on a lane track

I'll do some more tinkering tomorrow. Burned out right now. My son's derby day isn't until the 28th of April.

Re: Testing your car on a guided track,when racing on a lane track

My car as of right now is as follows.

Back /----\
Front. Raised [---/ FEW

But I need to make sure I have the back wheels straight up and not left or right of center. Meaning the bend should be at 12 oclock and not at 11 or 1.

Re: Lanes width for none center guided tracks?

Thank you Vitamin K. Looked on the net and no real answers. I got some supplies to make an 8 foot test board. I'm using half round for the side rails but I'm not sure if they are going to be too tall. I'm going to put a slot in it so that my start gate and timer can be added to this board.

Re: Derby Magic Test Track

The plastic is rigid but the joining pieces have play. You have to make sure they are aligned correctly. My thinking is having the track fixed to some thin wood would fix this issue. Home depot has some thin pieces of cedar that would work perfect. I think you can get a pack of 12 for $24.00. I have...

Derby Magic Test Track

The track is together. 1. Plastic board that is used for the start gate was not drilled correctly. Easily fixed but as someone that uses a Bridgeport there is no excuse for it not lining up. Also had to make clearance for a pin used for the switch. It was catching the board and not letting the start...

Re: Testing your car on a guided track,when racing on a lane track

Had to re drill the holes to make it work and had to move a piece forward. Also a pin was stopping the starting pole that holds the car from going under the track. I had to modify the plastic piece to get clearance for that pin. Basically the starter pole releases but the car would roll over the pol...

Re: Testing your car on a guided track,when racing on a lane track

I'm putting the starting area together and the plastic piece that holds the starting mechanism was drilled incorrectly.

Re: Testing your car on a guided track,when racing on a lane track

Correct, my first idea is to get some thin ply wood and use if that can be attacked to the frame.

Re: Testing your car on a guided track,when racing on a lane track

Ok. My NDFW is raised. I did get the single 32 foot track from derby magic. I will post something about it. It should be at my house when I get home. Storage and price is why I went with it. The timer and program is a steal when it comes included. ( Wish I would have found this group befire a bought...
