Default off-road Bar Stool Racer

Hi, This is my first post. Great site

I'm thinking about building off-road Bar Stool Racer. I'm just in the planning stages right now. I'm not looking for speed. Just something to buzz around on in the camp ground. Ideally something with higher torque (I'm 200lbs) so it could pull kids in a wagon. I'd like to keep the costs down so nothing fancy, just practical.

What are the best part sources that I should know about?

Anyone care to share lessons learned, do's & don'ts in this type of project?

I'd love to see some links to projects of this type.

Thanks!

Welcome! Please fill out your profile(location) as it helps when asking for help. As far as an off road barstool.racer, well you wont find one,i dont think. Typically, thats for the street/pavement. You could however build something simular, and just use atv tires instead of the normal "racing" tires/wheels....
Use a 8hp engine with a tav2 tc and gear your drive line for like 7:1-8:1 . You wont go REAL fast,but you can pull a bunch of kiddos ALL day.....ACTUALLY, I think a HF 212 cc 6.5hp engine would work just fine as well, @ 7.5:1-8:1.....

Location updated . I can get the parts from Canada or US.

I also read something about 'jackshaft'. Not sure if that would be less $?

It doesn't have to be that fast. I guess, I want bar stool rider, not racer. LOL. So small ATV tires should work.

Well, with the right size atv tires, you can hit a 7:1-8:1 with no problem and no jackshaft, unless you dont want/cant shell out $130 for a TC (transmission) . If you want/need to go Cent Clutch, you will need a jackshaft to get to a 7:1-8:1, but thats not hard to set up or real expensive. For tires ,maybe something in the 14-16" height tires....

I'm sorry, but an off road bar stool 'racer' ??
small footprint, very high COG... that doesn't sound like a good idea at all.

Anyways...
I think I'd increase the ratio even more as to what Jim suggested.. maybe 11:1 or 12:1
to add torque and reduce speed.
12:1 on 14" rear wheel diameter for example
would be 12.5mph [20km/h] with enough torque 114ft lbf [154Nm]
to move at least 600lbs (bar stool, driver, trailer and kids)

FYI: that kind of ratio will need a jackshaft which simply provides compound gearing

Thanks guys. LOL. Keep the ideas flowing. Barstool is just the initial idea. I may go with a cooler, keg or maybe a big *** La-z-boy recliner. LOL. Something different for the campground were most people have golf carts. I can go with wider wheelbase if needed.

Prices are better in US anyway and I live only 1hr to the nearest US parcel place. Can you guys point me to some online parts sources? I'm mainly interested in parts like wheel hubs, axle, sprocket, brakes, throttle.

Do you recommend sprocket on the engine shaft, clutch or other? I was thinking of using some small motor for this project.

These sound good. I don't need to go faster but I need the pulling power. Is 1000lbs possible?

Yes a 1000 lbs is possible, its all in the gearing..... just change sprockets....
You can use a HF 212 predator. I like the lazy boy idea better. Think about it,you got your spot at the house dont you? I know I do.... Now you can take your spot with you..... You tell your daughter, "sure ,ill babysit the grandkids...." And you do,from the comfort of your chair,with them in tow..... lol

hm 16:1 overall ratio should pull 1000 lbs, but you'll end up with a 'top speed' of less than 10 mph.

Maybe this is when you want to consider getting an engine with about twice the amount of power (11-13HP)

Wow, that HF 212 predator is cheap at $120.

However those torque converters seem to be over $200 at NorthernTool. Any other places that I should consider? What make/model do you guys recommend?

MFG Supply
BMI Karts (prices are good but the shipping stings a bit
Go Kart Supply

You can also try Princess Auto; other Canadian members speak highly of them.

A genuine Comet will cost you around $200, you can get a clone for around $150 but, at the speed you're looking at & the fact that there's a jackshaft in the mix, you're probably better off with a centrifugal clutch... so long as you don't try climbing any hills
