2016 - My go kart rebuild

[David Ham]

Sorry if you have already posted,but what size springs are you going to use?? Hard to tell scale, but they look like quarter ton ??? No torque converter???

I don't know what size springs they are, but quarter ton could be right. I will never buy suspension off the internet again! they are much too stiff so I had to hinge them right up close to the frame to get any movement. And no I don't have a torque converter but I think I need one. do you know a thread about them so I can educate myself??

alright some more pictures:
My biggest angle grinder at 2100 watts, cuts very nicely.
I finished building my front hubs today:

enjoy yourself:

Its still got a fair bit of work to go but its up and rolling.

Ok yeah! that big angle Grinder will mess you up in a hurry! WOW.
I nicked myself a couple times with the 4".
All I was saying is "One does not simply nick themselves with a circular saw!" LOL

 

[David Ham]

yeah
so I did a bit of work today.
besides cutting steel and humans very well, the big angle grinder also sets clothes on fire.


and I got everything up here all nice and functioning, no scraping metal when the wheels turn so i'm happy with it.

bit of aluminium to sit up under where my feet will go.
also got the throttle satisfactory, so Im predicting a test run and video within two weeks.

Dude Your on Fire!!!

 

[Functional Artist]

Honey, get the hose!

6.5Hp's on fire again.

Your Karts lookin' good!

Can't wait to see the test drive.

 

[Kartorbust]

Nothing beats the thrill of being on fire...both figuratively and literally speaking. You should have been wearing the brown pants when that happened lol. Hope you didn't burn your skin too badly.

Turbo lag? Oh you mean the courteous head start.

 

[David Ham]

I didn't burn myself...
two weeks might have been a bit optimistic, but we'll see what happens...
I actually went out and bought something!!!

getting the paint going, I tested it on this electric motor and found out it takes a lot of work to remove rust!

disassembling.

 

[David Ham]

started painting today, it's brown!

and blue!

running out of brown paint but I should be able to finish it.
a lot of wirebrushing and welding and sanding happened before I painted, not very fun.

 

[David Ham]

So I can get a torque converter from a reliable Australian website (http://www.cutpriceracing.com.au/store/home.php) for AU$199 (US$152) I'm looking at a Tav2 30 with a #35 12T sprocket and 3/4".
I can also get it from two other places on ebay for AU$169 and AU$148 (US$129 and $113). I'm fed up with paying for things (I am 17 and don't have a job) so I think I will go for the last option unless someone advises me strongly against it...

 

[Poboy kartman]

To the contrary...we always buy the cheapest ones we can find...and no one has complained yet.

 

[Kartorbust]

Never heard complaints of cheap TC, just buy quality Comet belts which cost a premium.

A designer knows he has achieved perfection, not when there is nothing left to add, but when there is nothing left to take away.

 

[David Ham]

Alright, so I am puttign it all back together, although it still needs some painting.
some more painting
I am on the verge of ordering my TC...
Edit: If I don't use the cent. clutch, is there any chance of me reselling it, or should I just keep it lying around?
Edit: the TC is ordered! and it will turn up about thursday next week

 

[landuse]

You could resell the cent clutch, but you probably won't get much for it

 

[David Ham]

so, most of the painting is finished, I'll need some more but its going back together for now.

two of my finest welds

 

[David Ham]

I didn't post pictures of the front suspension setup earlier so here it is...putting the whole thing back together.

 

[David Ham]

cleaned up the shed today.

 

[David Ham]

So I worked a bit on the throttle today.
I wasn't getting full travel; the valve would not go all the way around so I tweaked some things and fiddled with things but nothing fixed it.

and then, I added this small bolt.

the problem was, The piece that this held in place was bending, and this limited the throttle travel. Now it works great, below are two pics of the throttle in idle and in open position.

 

[David Ham]

ran the engine today

and I tested the brakes, they're not very good. I might have to think of something else, my new bike has hydraulic disk brakes...

 

[David Ham]

so I went and picked this thing up today
Will install tomorrow

 

[David Ham]

Should it be this tight? I have looked at other pictures and it looks a lot looser, or does the belt stretch over time?
