Go Kart project

admin

Thursday:Friday:Today:Hope to have the rest of the steering done tomorrow.  It's only tack welded for the time being. Just want to make sure everything works before actually welding it together.  It's my first project and has been fun so far, I have no plans to go on but things have been going ok, not great but ok.
Reply:Sweet, looks good so far.  Cant wait to see the progress

Reply:what kind of tubing are you using? whered you get that rear axle and the brackets holding it to the frame.

Reply:Looks Great! Keep the pics coming. maybe I will build one for the grandson. Any idea about the final cost?
Reply:THe only thing I would change if I were making that would be to put the axel below the frame.  Other then that, looks cool.Owner of Welding Wiki,The free wiki based resource for weldor's around the world.http://www.weldingwiki.comWe have cookies!

Reply:Why are the spindle brackets angled back instead of straight?
Reply:They're angled because it won't turn sharp if they aren't.  They were binding on the spindle arms straight so we cut them at a 30* angle to get rid of that.I took it for ride today, still no throttle cable or brakes though. I still didn't go get any stock for the axel key but when I first went out it wasn't bad. I spun a full 360 on the black top, it was raining but I was still surprised that it would do it. It seemed like it went pretty fast for how long I held the throttle open. I'm going into town to get some stock right now, maybe if I get it together I'll shoot a short video.
Reply:I dont know if you have driven before go karts with no differential. I would recommend you to try one, becouse turning is difficult. Live axle wont work very well. Shifter karts may seem to use no differential but instead they have one special system in order to lift one wheel when turning so it will work like a diferential. If you are not going to use one I would recommend you to just power one wheel. Since it is very low powered and if you run it on street type floor you wont notice that just one wheel is powered. That is what go kart manufacturers do. Just my opinion. BTW it is looking gr8

Reply:One major issue you'll have is turning especially on asphalt. You appear to have a hybrid somewhere between a racing kart and a yard kart which is fine but you need to understand how a racing kart turns. You have a live axle and most yard karts have one of the rear wheels freely spin because there is no differential. Therefore it is going to push like a dump truck unless you can free one of the rear wheels up in the turn. A racing kart employees 'jacking' to accomplish this which is provided by the steering geometry. Typically a race kart has somewhere around 15 degrees of king pin inclination and 13 degrees of caster. When you turn in the geometry causes the weight to be transferred to the outside rear wheel while causing the inside rear wheel to lift essentially freeing the kart up in the turn. I've built a couple race chassis for asphalt road course. Check out my web page for some pictures. http://www.wideopenwest.com/~djcvelbar/

Reply:Here is a video of it. The first half of the video it's only going 1/2 throttle, the throttle cable slipped and my buddy didn't realize it. The second half or so it's going balls to the wall. 32mb'shttp://www.thebestgen.com/images/gokartmovie2.wmv
Reply:Looks like you're having fun and that's really all that matters with a project like that. I bet that thing would be tons-o-fun in the snow and ice!
Reply:If I can find some 7" wheels I'll be studding some tires to take it out on the ice.  I can't find a single one though.

Reply:so what is the longest that you guys think that a chain should be for a project like this.  I've got an idea on how to build a fun little go-kart/buggy deal, but there's one section where one chain will be really long.  Any opinions?
Reply:It's finished for now, I might put a floor in it next year if I end up putting bigger tires on it.  I'm working on a custom intake set up for it now but it has a custom exhaust I built already on it.  It's running a little lean at the moment though so I'm holding off on the filter for now.I painted it with some walmart 94 cents a can spray paint and it's not sticking to well but *I* think it looks pretty sweet.  It's all flat black for now, I think I might paint some of it silver.  I'm having a buddy make me up some beefier tie rods because the ones I'm using pretty much suck.  They bend if you look at them funny so I think I'm going to have him make me some 3/8" ones.Well here are the pics:     The brake set up I decided on, it locked them up on the snow easy and on the road decent. The exhaust, it's just conduit, I'm thinking of either getting a little breather filter for the end or a small muffler of some sort. Just a shot of the flat black.
Reply:If the brakes are locking up to easily, shorten the linkage arm to get less torque at the caliper.
