SMALL GO KART FRAME PROFESSIONAL
But we got our frame welded by a professional welder after putting all the pieces in the jig. Mig welding is better than arc welding as it is stronger and takes lesser time to master. The advantage of using square tubing is that you don’t have to make fish mouth cuts (which are time consuming). We used round tubing on the outside (30mm OD, 2.5 mm thick) and square tube on the inside (same specs). You can go for aluminum but that would be around 5times more expensive (a crude guess) and require TIG (titanium inert gas welding) but this would be lighter. The frame was made of a material(mild steel) called ASTMA 106 GRADE B. This makes the kart longer but easier to design.
SMALL GO KART FRAME DRIVER
Our go kart is a rear engine type (so that weight gets properly balanced and the CG remains on the center line irrespective of the driver weight). We used their design to get dimensions like track width wheel base, etc and designed the rest ourselves. We got a standard design for the frame, used by professional go kart builders(it was a side mounted engine design, so we had to modify it to make it rear mounted engine). Drilling machine(hand and vertical drill)Īnd a few other things which i donot remember as of now. Aluminum sheet for flooring (or CR sheet or zinc sheet which is inexpensive)Ħ. Round or square tube for the chassis (30mm OD, 2.5 mm thickness)Ģ. Materials you will need: (actually you need a lot, but these are some important ones)ġ. (in our case, we bought parts one by one when there was the need (please don’t do this)). That way it would be easier for you to design and think which parts goes where and how. It will be very helpful if you gather all the parts before you start the build. USE THREAD LOCKER ( FROM LOCTITE ) ALSO TO PREVENT LOOSENING OF BOLTS DUE TO VIBRATIONS YOU WILL HAVE TO USE A SPRING WASHER IN MANY PLACES, THIS WILL KEEP THE BOLT IN A TIGHT CONDIDITON AND PREVENT IT FROM LOOSENIGN DUE TO VIBRATIONS.Ĥ. FOR NUTS USE ONLY LOCK NUTS (ANY TYPE WILL DO – NYLOCK NUTS, DOUBLE NUTS, SLOTTED NUTS, CASTLE NUTS, K-LOCK NUTS, ETC.)ģ. I SUGGEST NOT USING ORDINARY BOLTS ANYWHERE.ģ. WHEN IT COMES TO BOLTS USE ONLY HIGH TENSILE BOLTS(PREFERABLY TVS or UNBRAKO BRANDED HT BOLTS). THERE SHOULD NEVER BE ANY SOMEWHAT TIGHT OR HALF TIGHT BOLTS.Ģ. )ġ.BOLTS ARE EITHER FULLY TIGHTENED OR NOT PUT AT ALL. WE NEVER FOUND OUT WHAT HAPPENED TO HER BUT IT WAS A LESSON FOR EVERYONE TO MAKE SAFE GO-KARTS.
SMALL GO KART FRAME DRIVERS
( ONE OF THE DRIVERS WHO WAS WITH US IN THE EVENT HAD A METAL ROD PIERCED THROUGH HER LEG, AND SHE WAS IMMEDIATELY RUSHED TO THE HOSPITAL. I WOULD SAY DON’T BUILD A GO-KART AT ALL, IF YOU CANT MAKE IT SAFE. SAFETY :- TRUST ME THIS IS THE MOST IMPORTANT OF ALL. And then, after the race when we were just enjoying driving the go-kart the left wheel just flew out of the rear was only after analysing as to why this disaster happened that I concluded it was because of not using the spring washer while securing the wheel to the wheel hub using high tensile bolts.)ġ1. (saying this from experience :- we had neglected using spring washers anywhere, so after every 7 laps or so we had to retighten the bolts on the wheels, this was real scary as we feared as to what would happen if the wheel came loose during the race. All fabricated parts must be hardened (heat treated).Īnd if you don’t have them bolts can come loose due to the vibrations and this is very potentially disastrous. Locknut and graded (or high tensile) bolts only.ĩ. Bumpers to stop wheels coming in contact with other kartsĥ. So, here is an instructable to help you guys build your own go kart!!!!Ĥ. It took around 30 days for us to fabricate it (it was our first time). This was fabricated for a go kart race event held in Bangalore. INTRODUCTION: Hello makers! This is a go kart made by 12 engineering students (from Siddaganga Institute of Technology, INDIA).
