Next I started on steering support. that was in August 2015. As can be see on my ebay purchase summary for on/off switch: I made a simple mold out of sheet metal: In that I vacuum infused a carbon fiber part with some wooden structural inserts. The back of it isn't perfect, but decent...

Components may be too big of a word, but my whole front, I call it "suspension" is based on Delrin acetal. Out of 5/8" bolt and two shaft collars, my friend welded a spindle for me. The only other welded thing will be a steering arm. Since I couldn't calculate the spindle arm angle at the...

There is surprisingly little choice in aftermarket go-karts adjustable pedals... So I build mine out of carbon fiber. Back and front stopper incorporated in design (if you have flat base for it to act against). But even at 3/16 it's still a bit too flexibly twist-wise for my liking, so I'm going...

Yes, delrin acetal is great. I tested a piece and it's indestructible, yet light and machinable. The miracle of the modern science! I also used it in the front suspension / steering mechanism, which I'll come to soon

I thought for a looong time about how to mount go-kart seat to a flat floor. It's awkward idea from any angle. I thought about using the usual go-kart style supports and mounting them to longtitudal t-slots. But it would complicate thing, and won't look pretty. In the end I decided to mount it...

When I picked up the project this summer, I started with motor mount. I gave some thoughts on materials to use. I have only simple tools, and no access to router,cnc or laser cutting. So after researching some, It looked like Derlin Acetal is the stuff I need. Light, strong, stiff, easy to...

The gear ratio on motor and shaft is now 11:90. The whole thing with driver is <110lbs. According to my calculations it should and does take it to 12mph with no problem and pretty good (but not neck-snapping) acceleration. Because I have to make an effort to keep up with it on mountain bike. For...

Carbon fiber cured. It is pretty beautiful Not exactly perfect on the bottom, but only the ants will see these imperfections A few (very itchy) hours later: Weight of the whole thing? Under 5 lbs! It came out even lighter than I expected. The panel, suspened at corners, can hold my...

Bought Bridgeston go-kart tires, 5x5, slightly used. Made a mockup to see if it's a viable project: Rear bearings in lightweight plastic housing: 80/20 aluminum extrusions, 15 series for the longtitudal part of the frame. 96 oz when cut to size. Which is 38" long. That'll be almoust all...

That is really cool job! What are your pedals made of? Is it steel or aluminum and how thick?

So it's same #25 I guess. Where do you get sprockets for that? Or did it just fit the sprocket that already was on the kart?

Great conversion. What chain/motor are you using exactly? I'm currently working on my second electric kids kart: http://www.diygokarts.com/vb/showthread.php?t=24528 Most of the motors the sell here have #25 chain sprockets, that's what I used on my first one - 250w @ 24v, #25 chain. But then...

Yes, yes, I got it. No more stupid questions :)

It looks like that thing can cut up to 1" of material? But that's probably something soft... If it could cut 1/2 aluminum and I had something like that in my garage - my family would lost me :)

Just were did I suggest for somebody to work for free? Gosh.... I asked for people to share shops they use. Got two pages of everything but... Those 8 pieces are 3/8, 16" tall, and were made for under $400, here in US. By the emachineshop. Immediate online quote and ordering. The place is...
