Howdy folks,
It's been a while since I posted here but I'm about to build a go kart so thought I should post it here. It's going to be vintage-inspired in that the frame should have a vintage feel to it, as well as the engine. other than that seat, wheels etc won't really be vintage hence the name. I've made a cad model of the frame already (although it might not end up looking exactly like this):

I already have most of the parts, and have built a pipe bender so I can get started pretty soon, study permitting.

In the last week I've bent the first part of the frame and attached the c bracket for the spindles. It can now stand on all four wheels. in the bottom picture you can see that my spindles are quite long, I'm thinking of either cutting a length out and welding it back shorter, or else if I can find a nut and die to fit the 17mm spindle just cut down the length and put a new screw thread on, which would be a nicer option.

Steering: Done (y)... sort of
I've made some crude attachments to hold the cheap steering rack on, cut the tie rods to length and made a steering shaft. Alignment is a little bit wonky at the moment so I'll probably cut the part of the frame that holds the steering shaft and try again.

Minor update, I've put together most of the back part of the go kart. I also cut off the steering wheel support and started reworking it. Instead of welding the tube underneath the support I figured I could put it straight through, which I think is much nicer. My holesaw broke so I'll just notch the rest with the grinder.

Nice clean lines !

How are you making your bends and what is the size of the tubes or pipe you are using?

thanks :) the OD of the pipe is 26.9mm (a bit over an inch). I built a pipe bender after the two cheap benders I got didn't work for me (one didn't have the right die size and the other was manual and couldn't bend it). Heres a little vid I made:

Big update! finished up the engine and jackshaft mounting parts, steering shaft support, and seat supports. In the last picture I put everything together that I could so far. The reason I'm using a jackshaft is I don't know how much power the engine will produce, it might not be much but if it really goes I can remove that. Unfortunately the steering rack is right where the pedals feel like they should be, so might have to put them in top or something.

Got a couple of small things done, drilled the holes for mounting the jackshaft, and put together a brake caliper mount. I've got a friend who made his own plasma cutting table and he's cutting some parts for me, including an engine mount, foot controls and base plate.

Alrighty, got the parts from my friend finally, and started putting them together... so the brake is all connected, since the line wasn't long enough I had to do this workaround solution using leftover tie rod. Right now it's pretty much done I just need to get the engine going and there's still a lot of work in that.

That's actually a cool link addition :cheers2:

Now the missing cylinder may be part of the running problem :unsure:

😛:bannana:
Haha thanks
hmmm should have thought of that:unsure:

At the moment progress wise I'm just waiting on some parts for the engine... and have to figure out what to do for the exhaust. In the meantime I put together a little time lapse video of the go kart build :)
