Engine?

[usman111]

Hi,

Im have been looking to make a go kart for a while. I would like to know if a pit bike engine would be suitable, in particular this one:

Thanks

hey welcome to the forums.

depends how heavy the cart is. would be fine in a smaller kart.
if it will be more than 350lbs total (with u in it) than maybe get a little bigger motor.

think about how much a pit bike weighs/resistance then think about ur cart.

good luck

I'd probably choose the Lifan 110 they sell for 6 pounds more. Otherwise yes, that will make a nice shifter kart.

if i recall most off those type/size engines are about 7hp, that put with a 4 speed will get you going pretty fast.

What type of welding machine and amps should i buy and brand?

Price range is the determining factor. Shielded MIG welders are the easiest to use and learn. Followed by flux cored wire feed welders. Then stick. Lastly, is TIG. It's the toughest to learn but produces great welds and is very versatile. Shielded MIG is literally point and click and out comes nice welds. The minimum amperage is 90 amps. Many people have made karts using the flux cored welder from HF. It's about 100 bucks but the wire is poor quality and expensive. I prefer MIG because of its simplicity and nice results. As for brands, there's a few that dominate the quality welder market. Lincoln and Miller are the main two. Hobart and Craftsman also make good equipment. The HF stuff will work well but, just like any other HF tool, there are no guarantees.

Wow those are pretty expensive. Is there anything cheaper and affordable for a 16 year old thats easily available in the uk?

pick up a nice arc welder for cheap, make sure it can be adjusted and also a named brand of rod (6013) makes all the difference. I use hilco red 6013, a pleasure to use.

I call BS. Point and click for decent looking welds. But a strong weld requires the right settings and the right weld speed.

i think he means it is alot simpler than stick and alot easier to get a good weld

i have had many uses and engine swaps over the yrs using my trusty flux cored wlder,i had it for the past 11yrs or so so i think i have gotten pretty good with it,worx for me.keep meaning to upgrade but i have found no reason to put it to the side just yet for what i do.

 

[Bluethunder3320]

today i got my own first welder, its a HF 90 amp flux. got it for $110 and got to try it a bit before dark, works pretty well (other than high splatter probably because crappy wire)

ive used a lincoln (i think?) 250 amp stick welder at class with 70 and 110 series rods.

why 110? because my class gets them for free somehow. they use them to weld submarines together.

I call BS. Point and click for decent looking welds. But a strong weld requires the right settings and the right weld speed.

In comparison, it's much easier. The machine usually GIVES you the wire speed and amperage. The proper welding speed can be picked up in an hour. I was taught the basics of welding in one class period, 42 mins. Then, I was set free to weld and go get my progress checked by the teacher. He'd throw out a pointer here and there to improve until the welds were strong and appealing. Which is easier to learn, TIG or MIG/flux cored? Which is easier to control in areas such as interior corners on karts, MIG/flux cored or stick? In comparison, it is point and click.

 

[fowler]

yes i learnt with mig then i tryed stick with was ok but trying to weld any but on a flat surface welds horosontaly was imosible

 

[redsox985]

My point exactly. If he's learning to weld, or buying his first machine, you can't beat the ease or versatility of a MIG/flux cored welder.

 

[daftmachine]

Maybe its just me, but i dont think Arc welding is that hard, okay it sticks some times, a little practice and u'll be fine.
maybe this one http://cgi.ebay.com/HD-100-AMP-ARC-WELDING-MACHINE-WELDER-ACCESSORIES-NEW-/180571836750?pt=BI_Welders&hash=item2a0aeb914e#ht_2344wt_906
but the ones that know alot about welders may say something is wrong with it, just a idea.

i just weld, i dont know much about them.

 

[redsox985]

Flux cored wire is more practical than MIG because it doesn't need shielding gas and welding outside with a breeze blows away the gas and oxygen is exposed to the weld and it just doesn't work properly. For a cheap welder, a HF $100 flux core welder is your best bet, but I would spend a bit more and get the once that can be converted to MIG so that, in the future, you have that ability if you desire. MIG produces nicer looking welds than flux cored but has it's limitations.

 

[daftmachine]

Well still would anyone answer my question is that little thingy enough ^ or is it too suckish course if he will go with a mig welder and the other one is fine enough, ill buy it for sure

Hello again didn't want to start a new topic, where would you measure the diameter of a king pin? Because i ordered some but i think they are 8mm not 10mm like it says in the description because they dont fit on the 10mm bearing snugly:
