How to build a BSP BASIC saloon chassis.

To build the kit you will need: .047 wire, .062wire .032 id brass tubing, and .062 id brass or stainless steel tubing. Building of any slot car chassis requires care. Please ensure that you wear protective eye glasses and only use tools in the recommend way. Soldering should be done in a well ventilated area.

The order I build the chassis is not the only way, but is a method I have come to from building many chassis.

Below is a picture of the chassis frame. The pieces locate into the slots marked with corresponding letter.

Solder all the parts in their correct slots and the chassis will look like this. You should not have any parts left over once you have done this. The guide locating and strenghtning post is a 3/32 axle cut off. Part e sits with the larger hoop on the outside of the chassis.

The pan sections like this...

The next task is to make the spine hinge. For this you need the .062 wire and the .062id tubing. I use the stainless steel, as this is stronger and wears less, but is far harder to solder. The front part of tube is around 5mm, the rear 10mm in length. Solder these into position first, and then insert the wire to make sure they line up and the wire can twist with no resistance. Bend the wire and then slide into position to make sure the bend is correct, trim off any excess, and solder to the motor box, ensuring the solder does not flow into the tube.

Each pan is attached to the chassis centre using 2 pieces of .047 wire. Each piece should be around 10mm long. These pieces are soldered to the pans once they are in position. The up movement is controlled by the hoop on the front on the chassis.

Finally the chassis requires pin tubing which are soldered into the 4 supports. A lead wire retainer is also useful, located infront of the spine. Front wheels are supported using pins slodered though the hole on the inside of the H slot. This car has got BSP lexan liteweight fronts.

Your chassis should look like this. Give the whole car a good scrub to deter rust, and attach the running gear and motor.

The car that won the Barnton BOC was using : BSP Blueprinted Proslot motor, BSP tyres on 10mm hubs, gearing 6/36 with a CAT 307 bodyshell.
