Hello, world! As you might know (because you've never seen me here and because I'm posting this here), I'm new here and I want to build a go-kart, concretely an electrical one, I don't like contaminating. I've already reviewed the Electric Projects section including the two important motor selection sticky posts, so no need to tell me about it :thumbsup:.
Now, I'm going to introduce myself. As you might be able to see in my profile, I have a relatively extense knowledge of both digital and analogue electronics & programming (including embedded systems), which will certainly help me in my project (by building my own controller and even my own motor). I have a 3D printer, so I can print plastic parts, but I don't know how to weld metal parts nor have a welder, so I'd probably have to buy the frame & other important parts. At my local kart circuit they sell frames with direction and everything included, but they start at more than 1600 €, which is way too much! It'd probably be more expensive that everything else combined! So if someone knows a cheaper way of getting a frame, please tell me.
That's all, folks! Thank you in advance for your help.

Hello and welcome..

Have you built any electric motor from scratch before?... I'd like to hear...

Nothing like spending a bunch of hours to wind coils, only to find out it turned out in a rats nest of molten copper and burnt wires.... Cause it wasnt insulated enough... Or the like...

Just sayin...

uhh winding coils... :eek:

Anywhoo, kart chassis..

look on ebay and local classifieds (segundamano.es, wallapop.com, ...you know better than me), they pop up every now and again in ALL priceranges!
I'd bet you'll find something decent for a good price if you're just patient enough.
look at this for example:
https://www.milanuncios.com/buggies/chasis-kart-mw-247741348.htm
not bad IMHO..

(anyways searh for kart [NOT gokart, or "go kart"] and look in motor or sports categories only..
some sell them by tonykart, birelkart, topkart etc... w/o no go anywhere :D)

Ahhh yes winding coils... Good times.... Tedious... But when you let 'er rip without seeing smoke and/or fire... But a gentle hummmm.... It is good to see...

Hello, thanks for your help. As for the chassis, there's one thing that's been worrying me: where do I put the batteries? They'll be heavy and bulky, so it's not trivial.

indeed an older (1980) gx200 powered (ideally belt driven) rear engine concession kart would be the best thing to start with..
much larger (much heavier I'm afraid)
but lots and lots of welded bumpers and nerf bars and stiffening plus it being longer with the rear engine setup ...
so enough room to put batteries, a fridge, a 42" TV and whatever you need to make yourself at home ;)
(No honestly, they're mostly cheap IF they pop up... but they're only few and far between by now..)

A standard racing chassis (adult, not bambini ;)) should have just enough room for all your needs though
two might fit behind the seat, one or two could be mounted under the steering where the tank sits originally...
And if you weld in the nerf bars, they too provide room (stiffened up) for at least two or three batteries each .. makes a total of up to ten small'ish car batteries if bad comes to worse.
six at least.

Yes, there will likely be some welding involved, but nothing too bad imho.
not exactly trivial indeed, but no rocket science either ;)
