A few words before I get started:
I'm not sure how many people are aware of this toy. I've never seen it sold in India in any toy stores. Even in the US when I used to live there around 15 years ago it wasn't that popular.
So what is it exactly that I'm talking about? Welcome to:
SLOT CAR RACING!
So what exactly is slot car racing? It's a toy consisting of a track with electrified rails and cars equipped with DC motors. The track has two lanes and each lane has two electric rails. When the car sits on the track it has 2 metal "shoes" that make contact with the rails. These shoes pick up the electric current and turn the motor which then turns the wheels. Each lane is connected to a wired remote that just has a simple trigger. This trigger is used to control the speed of the car. The more you press the trigger, the more current is delivered to the motor and the faster the car goes.
My racing set is made by Tyco and I picked it up in the US almost 20 years ago. I used it for a little bit as a kid and then it was packed up 12 years ago and completely forgotten. When I opened it again last week, it had 12 years worth of spider webs and dust and I had no clue if it was still going to work.
The first task was to clean it and make it nice and shiny again. I had no clue how to go about it so I decided the first step was to get rid of the dust. I needed to see if the rails were rusted which would make getting it to run a whole lot tougher. I started searching around for a can of compressed air to blow the dust away but that turned out to be a task in itself. I went to all the hardware shops in my colony and then to some industrial areas in my city but no one even seemed to know what it was. Frustrated, I turned to eBay and found one seller who had a large stock of them in India. I ordered a couple of cans (approx. Rs. 330 each including shipping) and they took a week to arrive. The somewhat slow shipping is because this item is not allowed to be transported by air for safety reasons, only surface transport is allowed.
Having finally got my hands on the compressed air, I was able to blow away all the dust and spiders and spider webs (shuddering the whole time because I'm scared of spiders). Thankfully the rails were not rusted but there was a bit of oxidation on them. So the next step was to get rid of the oxidation so the rails can deliver power to the cars. I bought 1000 grit sandpaper (a.k.a. emery paper) and very gently rubbed it over every single piece of track and they started to look shiny again.
By the way, compressed air is relatively safe when used properly but is dangerous when used improperly. It should always be held upright and must not be shaken before use. It contains some kind of propellant and the bottle becomes ice cold when in use. If shaken or slanted too much while spraying the liquid comes out and instantly freezes everything it touches for a second. It can even cause frostbite on skin! Here is a link to a video that explains how to use compressed air safely:
Finally, I wanted to apply some anti-rust on the rails so I started looking for a can of WD-40. Finding it was an exact repeat of the compressed air scenario. No one knew what it was and the one guy who knew didn't have stock. I again ended up ordering it on eBay and it again took a week to arrive because it is also not allowed on flights.
I read that spraying WD-40 directly on plastics is harmful in the long run so I sprayed it on a cloth instead and rubbed it over all the track pieces and they were finally ready to be assembled!
This is what the tracks look like:
They just need to be pressed together and the tabs snap into place to hold them securely:
Here are some closeups of the car and motor:
In the pic above you can see the motor armature that's connected to the gear which turns the rear wheels. You can also see the metal contacts ("shoes") on the front that pick up the DC current and transfer it to the motor. There are 2 magnets just in front of the rear wheels that stick to the metal rails on the track and keep the car from flying off. They're needed because the cars can go really fast! Finally there is a guide pin between the metal shoes that goes into a groove that runs all along the track.
Here is a pic of the car when it sits on the track:
These are all the cars in my "garage"
This is the remote gun with trigger that controls the speed of the car:
This is the section of track that provides power to the lanes. We have to plug in the DC adaptor and 2 remotes:
A close look at the power track:
This section of track is for switching lanes. Adds some excitement to 2-player racing!
This is the instruction manual. It includes 2 layouts for the track, one for 4 players and one for 2 players:
