| Fantasy CycleKart builds | |

| Whilst enjoying a small eggnog this yuletide, I got to | |
| scratching the old bonce about what would be the ultimate | |
| cyclekart build for me as a technical challenge. After building | |
| the Auto Union, which took me about a year, I vowed that the | |
| next build, if it happens (high probability) will be a simple | |
| basic cyclekart. That said, back to the topic. | |
| Question | |
| If you had a big spacious workshop full of all the machine tools | |
| you could need, all the time in the world and the skill to build | |
| it - What would be your ultimate cyclekart? | |
| So, answers on a postcard* (*read post yours below) With an | |
| image and why that pre war car for you? | |
| I will start the ball rolling with the 1935 MG Type-R Monoposto. | |
| I would build this as it looks great and it would be a good | |
| challenge to get both front and rear double wishbone torsion bar | |
| suspension working and lightweight, Rick Eggers in the states | |
| has already done work on the torsion bar system for his | |
| cyclekarts, this would need to take it even further. The body is | |
| fairly complex too. | |

| Hi Jim, another MG for you, MG Magic Midget 1932 first 750cc to | |
| reach 120 MPH. Another plucky Brit. Super Streamlined Austin | |
| Seven 1935. | |
| Regards Nick | |

| The MG-R Type is full of potential for a "Full House" Cyclekart | |
| build. | |
| ie. Front and rear torsion bar suspension and low and | |
| lightweight. | |
| Its got me thinking that this will be my next one ....!! | |

| Nice Nick! getting in one of them might need a removable canopy | |
| to keep the look. Good fantasy builds, keep em coming. And rock | |
| on Jon! I would love to see that one done. | |

| Interesting that torsion bar suspension is a recurring theme! | |
| It does make for very space efficient suspension, which is | |
| probably more important in a cyclekart than a full size car. | |
| In case anyone wants to take this further, I did work out a way | |
| of adapting trailer 'indespension' style suspension units which | |
| may be of interest to others. Most of these trailer units are | |
| too stiff for a cyclekart and are made as a single unit so they | |
| can't be welded without destroying the rubber. However, there | |
| is one company 'Watson-Jones', who may lightweight units (150, | |
| 250 and 350kg) that can be disassembled. This allows you to cut | |
| and weld the suspension arm to the length and angle needed for | |
| your project. You can then reassemble it afterwards and damage | |
| to the rubber part is avoided. Doubling the length of the | |
| suspension arm (originally 75mm) halves the effective spring | |
| rate of the unit and also makes them easier to incorporate into | |
| a suspension design. | |
| I investigated this when I was thinking of building an ERA or | |
| Auto Union and I will be using an adapted version of the units | |
| that I bought for the top radius arm of my Riley IFS. | |

| The rubber type suspension can work very well. If you look up RA | |
| Vanguard which competed at Goodwood recently, that had bungeed | |
| cord on the front, both as spring and rebound. Issigonis | |
| Lightweight Special also had rubber, of course original Mini did | |
| too. When we built a very light back end for a mini the | |
| "doughnuts" received a lot of holes. (Drilling rubber isn't fun) | |
| Another very light car I had peripheral involvement with used | |
| squash balls in comprssion, they come in various hardness. They | |
| were in a tube with a plunger acting on the end of the ball | |
| "stack" | |
