buggy go kart thing with overpriced cm250 engine

[fowler]

i think i f***ed the design a bit cause it is going to be 2.3?2.4 metres long
(10cm shorter than modelengieers sidewinder)
can anyone find the length of the tray on a toyota landcuiser ute 70 series

 

[Kaptain Krunch]

i'd re-do those motor mount welds...

 

[That One Guy]

Length of the tray?

 

[fowler]

the distace from the back of the cab to the back tailgate is the tray
the problems fixed as i remebered our generator trailer
ill proberly go over all my welds again all my welds again anyway
at the moment it looks like i might be redesigning them anyway

 

[lemegacool]

when you are welding relatively thick metal try to chamfer the edges with a grinder... makes the weld look cleaner and is MUUUUCH stronger...

-----\/------ plus you could get your hands on a sandpaper attachment for your grinder with a couple meduim grit papers... it really brings a nice touch to the finish...

also flash is right... the proper thecnique is to properly set the gmaw parameters and weld in a straight line... its much more pretty than a weaved out weld

these pics are actually quick welds i did at work on my break lol...

in order fcaw t11 gas shielded and smaw 7018-1

sorry i hijacked your thread

 

[fowler]

that is qute thick steel
yes there are some very messy welds
i am improving though
i dont get this weld in a straight line thing everyone brags about
if i weld straight then it is a heaped line that looks like a trail of glue (if u can visulize that) it isnt anything like above

 

[r97]

sry for jumping in but when you say welld in a strait line do you meen make a dime/puddle/spot weld or whatever you want to call it, and then move halfway up onthat one and repeat?

 

[fowler]

whos that directed at

 

[fowler]

i gotta ask what u are talking about here
"fowler thats a pretty cool idea! and the machine make shure your frame doesent flex from its length and having the engine inbetween the axles, looks good so far, goood luck"
this came from the F1 indy kart thread

 

[r97]

i mean with no bracing (which he may add in later) the frame could flex from exsesive length read here http://gokartguru.com/metal_frame_go_kart.php its prob not gonna happen but it would be real anoying if it did

 

[r97]

its (the welding in stait line question) directed at flash and lemegacool

I was taught to make small circles or half moons when welding with a mig welder on steel. When using a mig, with spool gun, for aluminum, I was told to go in a straight line at a constant pace. With stick use circles to stir the puddle.

 

[r97]

im self taught and just do over lapping circles with mig. ive nevr had a chance to weld aluminum or use stick.

 

[The_Machine]

Yeah, self taught also. making good welds in my opinion all boils down to how well you have your hands rested near what you're welding. I hold the gun on my wire feed mig with 2 hands for maximum control and precision. the type of pattern I use I determine by the joint. sometimes half moon, sometimes slinky style. I was drunk as hell one night, and so was my friend. He said he wanted to learn how to weld. I told him my techniques in 30 seconds or so, and he did the most flawless weld. It's not a hard thing to do.

 

[redsox985]

Hahaha ya not difficult. I rest my left hand on whatever is nearby...my knee, a table, project, w/e, then use it as a rest for my right with the gun and go. Aluminum with a spool gun is fun. IDK what it is about aluminum but with practice, it just looks awesome.

 

[fowler]

i mite try the overlapling circles
and yes r97 there are another 2 side suports to go in and side rails that stop me falling out then i triangulate it all

redsox i have a challenge
if u can weld aluminium try welding two coke cans together
i here it is very hard

 

[r97]

ive tried that with tin cans and my mig didnt work to well (tin cans are steel plated with tin)

 

[fowler]

the boilys at work try it sometimes only one can do it

 

[redsox985]

When I get back to school where we have the mig with spool gun and correct shielding gas (I believe straight argon) I'll try it.

 

[fowler]

yes u use ally wire and argon
