![]() ![]() Your mileage might vary but it's the internet, we're all opinions at the ends of the day or you'd be buying plans from us.Īctually mine is both a 2-seater and a single-seater. This said, could indicate using heavier tube because its easier to weld for those not really versed in that skill. The fact that you're asking says that your welding is probably hobby skill at best and your weld is more than likely going to be a fail point. It's more about the build than it is the tubing. I routinely use 14g instead of 1/8 on lots of things I'm building needing structural strength without the weight penalty. If it's not going to see massive loads from jumping, have potential fire high speed impacts or a powerful engine, why over build it? The majority of the people building carts aren't engineers with solid works stress analysis plug ins and I look at what I'm building as a end use design. You can easily build this with 1/8th for the main frame and main hoops and design your bracing with triangulation out of 16g or 14g. Take those ideas into consideration.ġ0 gauge is you building a boat anchor for that. #Free off road go kart frame plans generatorWho is the user assuming risk? What is the environment it's being used in? This looks like a low power kart being built with the typical generator engine (predator 212 ect) and will have low suspension travel amounts as well as not being very large itself. My opinion is consider the safety factor first. Some good bracing however is surely enough to get away with 11ga (maybe even 12ga)īased on your design and the rudimentary form you're using as a model I'll assume a couple things. and a lack of experience isn't helping any either. Unfortunately perfect bracing is non trivial if you're aiming to reduce weight that way. Round tube makes it easier since it doesn't have a preferred direction. You can get away with 14ga if you add clever bracing. if you just fix the major flaws of the design you'll have plenty strength in 11ga Thicker isn't actually necessary I'd say. While being on the heavy side, it allows to reduce the total parts count and thus makes easier plans. KartFab's 1.25" 11ga a very good recommendation for square tube. Spiderkarts 1.25" 14ga recommendation is actually a good idea for round tube Since that and bigger is needed only because of your initial design When fixing these things you can easily reduce the tube gauge w/o any issues from the 10ga OPmini recommended Perfectly vertical uprights are just stupid in 99.9% of all cases especially for a roll-cage like structure. That front end will never be a good design with it being buttwelded to the seat frameĬontinuous tubes front to back to make a strong ladder frame (adding sidepods if you want the seat-portion to be wider)Ĭorner reinforcement need to be way bigger and tubes are to be preferred over plates. When designing a kart, it's best to know what forces are involved and in what direction they apply to a frame, Click to expand.yeah well that should change ![]()
