Ideas wanted for Go-kart
I did some searching in the news groups but didnt quite find what I was
looking for. I would like a project for me and my 10 year old son, he's quite crafty with his K'nex and legos always making some weird contraption along with the old pc parts and vcr's. So I thought it would be nice to move on to something larger scale, like a go kart or something similar. I know that horizontal shaft engines are easiest to convert and I should be able to find an old roto tiller or something similar, but have no idea how to make a working drive train from motor to wheels. I was thinking of making the frame out of wood and re-inforcing with angle iron since its much easier to shape. I was hoping that theres some diagrams or pics out there and maybe a few helpful hints |

Try any small engine repair shop for the parts at a decent price. You'll need a horizontal shaft engine, say a Briggs or a Techumseh. A centrifical clutch and sprocket assembly to match the shaft size of said engine, a few feet of chain and a final drive sprocket and shaft. Also drive hubs and wheels. I've seen some older models of riding mowers adapted for use as a go-kart. You might look into that also. |

I have no desire or plans to build a go kart, but as a mental excercise, it started me wondering how one would build the drive train with a *vertical* shaft engine...which are in much greater supply these days. In fact, I'd donate one if somebody wanted to try. One scenario would be of course, a twisted belt drive, where a twist in the belt converted the vertical torque to horizontal. I wonder if there are any small tractor or other purpose-built differentials out there. They could be shifted 45 degrees to point straight up.... Probably useless speculation...I just wondered if anybody had done it. jak |

I was hoping that theres some diagrams or pics out there and maybe a few helpful hints Most of them use a solid axel supported by ball bearings which can be ordered from places like McMaster-Carr. Normally a sprocket is then bolted or welded to the shaft and a chain connects that to a centrifugal clutch mounted to the motor shaft. Simple and generally robust. Make sure you design the steering and layout carefully so the weight is ballanced and the cart stable, I've ridden some that flipped very easily. |
