Before I explain how I've done the bodywork I must also explain that due to lack of space and money open moulding is the only option open to me to complete the work. The bodywork on the trike is GRP over foam formers. After much trial and error I finally decided to do it as follows. I used ply and foam to make the body panels up. When the former is sanded to it's final shape I let it rest for a few days and then cover it with aluminium tape I then lay up the resin and matting over the former. usually two layers and allow it to cure for 12 hours. I then carefully 'pop' the GRP off the former. Any more than two layers it can crack, any less and it flops and won't hold shape while you back it out. For large flat panels I laid 3mm core mat out on a flat surface and added resin. Once cured it's easy to mark out your panels and cut it with a slitting disk or hack saw blade in a jig saw. I used bits of ducting to make formers for the side duc...
Parts laid out on the jig table so i can start working out a few dimensions. The jig table has another 5 ft section to be fitted to it at the end closest to the camera in the wide shots of the front of the engine.
The seat has arrived. Now I need to decide if it's easier to use this as a pattern to make another once I've made a few minor modifications to it to suit my shape and size. I fit in it ok and it's comfy but the bulge under the knackers needs sorting and I'm going to make mine a bit longer in the seat area. I may also use a bit of marine ply to extend the back rest and then cover it all in foam and waterproof vinyl. I'm fitting the seat much like they would in a F1 kart, four struts bolted into the seat and then bolted to the chassis. Once the seat is in and adjusted properly I'll be able to work out where the dash bulkhead needs to go. I've got to get two roll over hoops that will mount on the rear bulkhead and fabricate two head rests to be bolted to the front of each hoop. The seatbelt mounts will be welded to the chassis once we have the seats bolted in. I'm using four point kit and I'm sure that they will be more than up to the job. I...
