Yip that is the next step. I dummy-ed up the engine tonight and it isn't exactly where i wanted it to be when it lines up so will have to do something different. I'm thinking solid mount the engine to the main frame and then make a side/nerf type bar going round it like a wing that can be replaced when damaged easily, Is that worth the exercise or am i wasting my time do you think? I will be racing it in the smaller ORANZ races just with the local club so i expect some damage to occur, I'm not 1 to be cautious when it comes to racing haha.

What type of engine?
Or you could make a tube frame, like a Nerf bar that bolts to the chassis & the engine bolts to that nerf bar.
Then the engine/nerf bar become a bolt on section.
At any point in the future a new Nerf bar & different engine can be fitted.
Make the Nerf bar protect the engine from impacts.

500cc single with reverse and electric start, Cagiva. If it all unbolts it will need stronger mounts than 6mm plates and tapped holes tho? It will have the lower bar with an up sweep that protects the lower side of the engine shaped like the wings of a sidewinder/piranah and probably a top bar coming along on the angle, i don't want it looking like a Midget side frame but want the protection.

This is a bloody nice buggy!

Just a shame it hasn't got a piranha rear :wink:

Or hole saw through the chassis tubes 1" & weld in 1" diameter drilled, (10mm) slugs.
Then you bolt right through the slug.
Real strong, does not weaken the frame & not too heavy.

Excellent tube work!

Curious why you went with the sidewinder though (instead of a Piranha with dual rear a-arms), and upgraded the front to the dual a-arms? Doubt its the difficulty, as your Sidewinder looks incredible!

And like Sloky, I like the progressive rate rear w/link. What's the link and dogbone from??

From the photos it looks like you might have a caster change when the suspension cycles, have you tried it?

Thanks tony, i will probably go with bosses in the frame to bolt through. Worth the extra effort and easier to use as well when its done.
I wanted a small buggy to play around with the big boys and when i started the project years ago i liked the look and smallness of the sidewinder so started that but over the years it just evolved a little :D. I figure if i can make it why not and i always take pride in my work so like to be different So suspension got changed and frame design etc.
The rear is modeled off my bosses Yamaha banshee but i make every part for it to work in the buggy and changed a few bits but the design is the same, I'm happy as how it worked out.
It has progressive camber and caster from about 5 to 10degrees through the working arc i think it was, its not setup ATM i just banged it all together for the pic. It should work out good i'm hoping (fingers crossed). Like the barracuda.
Any advice of the right setup angles when the buggy is sitting stationary would be helpful thanks guys

The Double A arm front for the Sidewinder & Piranha is modeled on the Barracuda design.
This also has progressive Castor.

You should rear mount the engine and go for a PIRCV style rear end!
sweet looking buggy.

Mike.
The Cuda obviously has a double A arm front end & the double A arm front that Russell Cartmell designed is based on that very same Cuda front.
It has similar geometry.

I reckon the piranha is too wide at the back for the front. (just my opinion as it looks a bit funny to me, nothing wrong with it) and i like how small this buggy is. I know im probably doing some over engineering on it as it only has the solid axle but i can't help myself :D
I can see myself in the future building a barracuda type buggy to do some serious off road as i love the build process, ill just finish this one as it is and get into the sport and see how i go, there will be a lot of learning from this one that will be good for the next.
