Feel very much the same way. Schools karting started for many teams in the classroom to give Design Tech lessons another level of involvement, mine certainly did. There were even a few built chassis still on the grid back in 2000. It speaks to a level of karting so many kids miss out on, even at the basic level of using a spanner and mixing your own fuel. It sounds gate keepy but getting your hands dirty has value. Looking forward to the rest 👍

So here is my two cents. Just know your first chassis is going to be drivable but not competitive. But that is okay. Your going to get done with the first one your going to want to build a second. So don’t get frustrated or discouraged. Fabrication isn’t something you learn over night. There so much to it. Ya anyone can notch a tube but it take time and experience to notch a odd ball joint and to get a perfect fit. Bending tube, I highly suggest buying a quality bender and make sure the bending dies are for tubing. When bending you want min deformation, you want that bend to be as even thickness as possible with min crushing. Welding the better the welder the better the weld in some sense. Iv seen some incredible tig guys do better work then me with a harbor freight welder. But for me i weld 10 times better with my water cooled foot controlled Miller. But I suggest you buy a welder ASAP and practice as much as you possibly can. Once you master that then start practicing welding tube joints. Now most company’s that braze they use a brazed lugged construction. Again there 20 dollar brazing stuff you can get and then there are exotic grazing rod and high end torches. Buy a quality one and start practicing. As far as steel goes, I know some company’s use 4130 chromoly, some use docol, and Iv seen some use DOM ( I would not use this) Some use a proprietary mixture they created in house. The thing your looking for is strength to weight ratio. 4130 isn’t all that much lighter but has a high strength to weight ratio there for requires less material to build. Ok as for the chassis jig think about it this way, it’s there to keep the frame straight and true and level. To keep the material from warping when wielding. So with that said a strong stand from floor to work height, flat work surface and the ability to securely attach things to. Iv built them with a wood stand and flare stock for a table and I just welded stoppers, up rights, and so on straight to it. Then Iv also spent but dollars building a jig that I could build production chassis off of. One thing is you can’t have to much jig. I know some high end kart chassis are welded under stress to duplicate the stress it’s under with full rigged weight, driver weight, and fuel weight going down a straightaway. Is that as important i don’t think so but I’m not a college educated engineer lol, I just go off of what I built and fucked up and then made better. But when using a jig just make sure when you bend a part and lay it on the jig that you secure it to we’re a fat chick could sit on it and it won’t budge you’ll be good. Good luck man. I 100% support this and welcome you into the world of fabrication good luck if you think you’ll maint any other hobbies once you start because all your money is going to go to tools, materials, and building. It’s addictive and good things because it’s time consuming, frustrating, painfull at times, and brain consuming. Have fun keep an open mind and welcome advice, fabrication is all about learning new skills to better your craft.

I appreciate this comment a lot. Unfortunately funds have run dry and that's that :(

As former product engineer, and now technical sales manager in a very competitive equipment industry, the number one recommendation is the following: JUST COPY WHAT THE MARKET LEADER IS DOING. They know more than you. Anything you change will likely be a step backwards. Who is the market leaders. For 100c and TAG...that is OTK. So what this means is buy a used OTK chassis...get out the drafting board, chop it up, and literally copy every single mm of it. Every wall thickness. Every angle. Everything. Building something is hard enough. Designing then building is just too much. Build first. Learn. Then maybe change the design.

Firstly, success of a product can be a result psychological factors not purely engineering. So following the herd isn't necessarily the absolute best route. Also, you always read the regs first. If I copied OTK I'd be making a kart potentially not eligible for Motorsport UK racing. Or at least not optimised for the UK scene. Secondly, if you're building a kart for yourself why follow the herd, that's boring. May as well go buy an OTK.

Can't wait to see how this project turns out. There have been a few smaller manufactures to pop up over the last few years, Air Motorsport comes to mind. May be worth hitting those guys up and seeing if they can offer any guidance on how you could go about it? A starting point could be to make a jig for the Tony Kart you have on a flat welding table and clone it as a start. Then you can start tweaking the design and trying other things/ideas with it

I was going to mention the Air boys but forgot! doh I think the clone kart route is the place to start I think, deffo agree there

Alan I wonder if you’re better off going with a known decent design that’s maybe got a more basic layout vs the OTK. Maybe even something from the 90’s, Fullerton?

Agreed. The Scorpian chassis built by Ian Williams looks good too
