92mph? My new Project, Racing mower! Craftsman / Jonsered LT12

Haha thanks guys.

I got to change the 820 parts eventually,
Now the rear sprocket will sit nice and low, also swapped the shifter rod and fork.

After its done and tested, I will reveal the drawings and measures.

Exhaust is done, Only welding left.



what ya think?

AWESOME I really like how this is coming together.

Thanks, it's getting there.

Got the steering shaft lengthened today, extended about 2-3inches, just cut and welded on a bolt. That way i also got the threads for "free".

Shock mounting challenge, I'm running out of space!



Think I will try to mount em like this:

I second that just add the waterjet as a whole

im guessing it doesn't mount like you want to because of the reservoir? Why not make the mount on the a-arm taller and just make a taller shock hoop?

Nah I dont wanna mount it the normal way. Takes to much room like that. I'm going to try mount it Formula 1 style. Like this.

In the + there will sit a ball raced hub.


So need to waterjet cut this now for test, just hope it works.

boy that seems like alot of complicated geometry to get wrong with a suspension like that. Good luck with that.

It's not that complicated. Its very well used in Formula 1, cause of low design and you can tuck away the actual shock. It's strange its not adapted for more cars, quads and so on.



But it's even less space on mine since the angles are so sharp.

I'm guessing your using this style shock system for space issues? Looks like you have plenty of room for a conventional shock tower, unless you are trying to keep everything under the hood.

On the steering, is the front bearing on the steering shaft getting some bracing? I don't have a good picture in my head of how you are hooking the steering to the spindles, but the front shaft brace looks weak.

I love the engineering and water jetting, makes for a clean setup.

Ya, but also I need the tank to be above the shocks, also I need to find room for the battery.

And I see what you mean, but the front steering shaft is getting its strenght from the rear brace. The only way it will move as a standalone is back and forth, when the steering shaft is inserted and tightened with the rear brace, it will be locked. - If it dont work as planned i will add an angular pcs. But then I will add weight, so fingers crossed, and thanks for the inputs.

Got the exhaust finnish'ed, but not tested. Also I almost didnt get it to fit after I welded those pipes from the engine lol.

I Tig welded the pipes from the motor, then I remembered how nice it welds. This was w/o filler material, also I remembered how friggin hot it gets. I kinda regret that i tacked it with the mig (those lumps), if not it would be perfect, but who cares right.










Wrapping an opposed flat head is the best thing you can do to it I guess, keep the exhaust REAL HOT!

Well isn't the wrap to cover up them welds anyways lol

Are you calling his welds bad...because mine are worse.lol.

Well you should see mine I'm using a might welder that came out of the trash lol his welds are actually pretty good he was just composing about the tacks just thought I'd try to make him feel better lol

Offcourse

u outta see my welds with flux core, lol, i hate the stuff ansd it hates me, XD

I want a flux core welder so bad.

And my welds was fair I would say, Haven't welded with Tig in ages. And there was 3 seams in those pipes.





And Ive started designing the gear shifter plate and chain guards in CAD now  , but photobucket phone app. wont work atm.

I ordered this, I might go the easy way out on the front suspension at this point in time. - then change it later, since I really wanna drive it before winter comes...

Will look like a mini car, or a big RC Car with these shocks:P



Also ordered this,

A Motorcycle Steering dampener.


And this, once I get a shipping quote,


Also enquired about Billet parts from Eccaburetors.com - but they don't normally ship to Norway. Hope they will, if not it might take 3months to get the parts.

The direct Steering Setup,

I Modified the Mini ATV tie-rods, Lengthened them with a pipe,







Then they will be connected with a Watercut part, (The one in the middle here).


The Chain guide/ Gear Shifter plate design in PA6 (Nylon) or (POM C, also known as Delron).

Cool steering, really good parts used as always. Not to get off topic but what time is it there?

10:44, soon Lunch

900 bucks for Billet parts for the Briggs & stratton Opposed Twin. That's excluding a HD Starter. + Shipping.

And also that's exluding the grinding I will be needing to do to the Engine, to get the billet parts to fit.
