Edge Taipan buggy with Ninja250

[StewieeeG]

Hi all. New here. And this is my first post. So I thought I'd share my buggy build I'm a 16 yo guy in Queensland Australia in year 11 and am trying to make a buggy.
I have so far cut and welded 90 percent of the frame. Attached an old Gemini seat on its raise in the frame, have purchased a 06 ninja 250 engine for my power plant. And an axle

I will post pictures soon.
I would really love to have a discussion going here and I will definitely need some help. So anyone and everyone's opinion is more than welcome and I'd love to get some feedback

Will be interesting to see

If u can
Try adding suspension
Don't wanna turn u away from the progect yet
But if u have done a bit of reading u will know this is a ball breaker

...& the Aussie numbers keep climbing...

Welcome Stewiee, can't wait to see the pics...

 

[MetalMech]

Curious to see this as well since this is one of the frames I am interested in.

 

[StewieeeG]

Yeah I have contemplated suspension. As I have 90 percent of the frame complete it would be hard to add to the rear end of the buggy without extending the frame length and width wise. For the front I could make some a arms top and bottom and attach the wheels and hubs to them no problem.

The frame is quite decent. I'm 6"2' and fit inside. I have a seat on slides though. It seems really strong with lots of adequate bracing and a large roll cage.
Here are the photos...

Nice to see another Queenslander here!!

 

[OzFab]

Nice work so far...

Unfortunately, it's a bit difficult to factor in suspension at this stage; you'll just have to rely on balloon tyres

 

[StewieeeG]

Thanks!
I will have to run a lower air pressure too, and my seat is fairly comfy too, I'll just have to Put up with no suspension
I thought I would stay another buggy as soon as this one is done, with suspension like a piranha or barracuda from edge.au

I need some pointers on the axle instalment, I need to attach the bearing hangers (photo) to the underside of the frame (photo)
Any ideas? Weeks? Bolt?
How to get it parallel?

First you need 2 pieces of heavy guage angle slightly larger than the pillow block (around 1/2" each way). Centre the block & mark/drill 2 holes in each piece. Get yourself 4 carriage bolts

of appropriate dimensions with nuts & washers to match. The flats of the bolts should just fit in the pillow block.

Once you have both pieces bolted to the pillow block, position the angles inside the side rails with the flat against the side of the rail & clamp in place.

Manipulate the angle so they are both in the correct position: The bottom should be level with the bottom of the frame rails & the distance from a common point to the axle should be the same from side to side...

Just ask if you need any more pointers...

Really
Coach bolts to hold bearings down

Hell no
They're for panel work

If they don't snap then the stupid square will round out and they'll be stuck

A nice grade 8 bolt 2 washers and a lock nut

The only place I've ever seen them used is on access doors on some ag gear to get into tanks
They still manage to vibrate, rub though and snap

 

[StewieeeG]

Yeah I shall get four heavy duty bolts and use them, but I need a heads up on how to align with the frame rails. to get them dead on because I don't want to be veering off to the right or left constantly...

Fabroman, I'm not sure what you are on about there I'm sorry. is there any other way to explain it?

Hell no

They are available in higher grades...

What part didn't you get?

 

[StewieeeG]

What part didn't you get?[/QUOTE]

all of it, maybe explain it in laymans terms with photos?

 

[fowler]

Heres my fully sick 3D cad spec drawing

hope it doesn't confuse u more

the top one is Fabromans method of attachment which is the far simpler
and will likely work fine

but as i like to over do the important stuff
id drill 2 holes in the frame rail then install crush tubes
they are just a piece of tube the width of the tube and the id of the bolt
the wall thickness is a few mm

u weld them in the frame then grind it flat
then bolt the bearings to it

the crush tubes are so when u do the bolts up they don't crush the frame

it may just because i build everything like its a bulldozer
i also hate fixing my own work

i just don't like the idea of the angle iron being able to bend and the holes getting flogged out

to get the holes in the right spot is just about measuring again and again

measure 3 times cut once

flip the frame on its back

the axle must be parallel to the front wheels not to the frame
so if u try to line it up to the frame then there may be small inaccuracy that u cant see and it will set u off

measure from where the king pin is going to go back to where u want the axle
each side should be the same
then measure from the king pin to the diagonal opposite side
again each measurement should be the same

the bearing have a small amount if movement in them so a few mm each way is in spec

I used option 2 on my daughters kart; the biggest problem with it is, once you drill the holes, there's no going back &, if the holes are out slightly, it can create alignment issues. The other problem with this method is that the bearing block is wider than the tube, creating an instability/weakness issue.

I used option 1 on my kart; much simpler & easier to set up & correct if it's in the wrong place. However, I also used a different type of bearing setup but, the principle is the same

 

[StewieeeG]

Wow. You guys are a great help!
Thanks a ton.

I will have to install the front axle first then I can get the rear lined up and it should be all sweet!

I will post updates on the bearings when I get around to it. But tomorrow I'm going to get the shed and do some grinding

I would also like your opinions on brakes. I thought of mounting a brembo front unit of a KTM and using that because I have brembo units on my bike and they shred some serious braking power!

What do you guys reckon.

[fowler]

Are u installing front brakes?
They're under rated for sure
The back is only good till it locks up which it will do a lot

But otherwise
Go for a heavy duty one
Is this a brembo from a 2 wheeler?
It will probably do just fine

Is it going to suit your disc?

Is it going to match the disc u have

 

[James.Ait.2013]

This is a build I want to see going. and its great to see another Aussie mate!

 

[StewieeeG]

Yeah its a brembo front unit front a ktm motorbike. They are extremely powerful.

It should match. They are a floating calliper and I can mount it easily enough.

I should suit the disc? Is there anything I should know?

Cheers James Australia FTW!
