I machined out these adapters for the front upper and lower A-arms (on the right is the better one)
I produced it from steel, because I didn' found someone selling 6061 T6 Aluminium. I think about painting it. But when the rodend will hit the paintet peace it will look very bad after a while, but without painting it will rust.


Have you thought of zinc plating the rod end spacers?

Hi S.W I thougt about it.
Yesterday I met someone who can order 3.3547 aluminium. It is quiet similar to 6061. I will try to produce the adapters of this Material and hope that is hard and flexible enough.

Unfortunality there is no more progress in the buggy project. In the first week of january I will try to run the FJ. I want to know, that the machine is running correctly before I disassemble it.

Do you know someone building a cuda with FJ 1200 Engine?
I measured the Engine and I think it will be very close to fit it in.

Sry, chrismas panic all around.
Only update: all "difficult" parts I let machine out by a workshop in the town, are basically ready. Only the holes needs to be drilled. So I hope to start hard in january.
When I got the parts I can measure all out for the next laser round. (ring gears, pedalboxes and update CV2; to fit in the Starter Engine and brake caliper of the FJ1200)

So I hope to get it rollin in february. :roll:

OK, the engine of the FJ1200 is running. We tested it yesterday without back exhaust. It was VEEERY loud :lol: , but it works really well.
Now I began to disassemble it. But to fit in this engine will be very close.

At sunday I will laser the rest of the parts (tank, chassis plates, wheelplates, sprockets, brakedisks and so on)
The machined parts are also ready (i will get them next time) and I ordered 16 wheelstuds.

Thats all for now. :-)

A few Pics...

The next 2 images shows the gearbox position. I'm thinking abaut extending the baseframe to get 8-10cm more space for the engine.
Image
Image

In this case the lower baseframe has to be cut off and extended. The rear uprights stands in an angle and the tailuprights also changing the position-angle.
Now the forces from the shocks are derived directly in the lower base frame after the changes the forces may not flow as Tony invented. :?:
Should I do It?

Looking good mate!

Regarding the base frame, if you can avoid extending it, that's what I would do. I'm not sure how far you can more the PIRCV cartridge back before affecting the shocks. I would assume there would be a distance which it would be ok (50mm??), but I'm not sure.

I've seen on another thread on here someone who did what you're wanting to do, and they put in another upright after the original shock mounting upright... Scroll about half way down on page 3. viewtopic.php?f=35&t=5088&hilit=poland&start=40

My buddy who lasers my parts was ill yesterday, so i worked at the engine bay of the cuda and the Gearbox alignment.
Thx Corey for the link to Jurus Cuda that helped me to imagine the needed changes.

So I cutted out the lower base frame and the rear uprights.
Image
I decreased the lenght of the last tube of the lower base frame..
Image
extended the baseframe pipes left and right 80mm and welded all together.
Image

Then I welded in new rear uprights.
Image
Image
The gearbox is spot welded and today I will weld the tail uprights.

The next target date to laser parts will be next sunday.
Then I can align the engine and chainline to fix the engine to the chassis.

I have decided to change the fuel tank position because of the fuel insert hight of the carburetor. Otherwise the fuel cant flow correctly. I also cant install a fuel pump, then I need to change the carburetors.
So I began to draw a 3D model of a new tank in Autocad 2017. I do not have experiences in 3D building so Im a little frustrared with it. Watching youtube tutorials does not bring the needed effect...grrrr

2x Sprocket adapter ring
4x Centre drive cartrige plates
6x Front brake disk
8x Wheelplate
8x Wheel adapter plate (I needed more wheel offset)

Tank looks great mate! Making it Aluminium or Steel?

Laser cut parts are look awesome too!

Putting one pedal in one box with two masters then a brake bias adjuster?

Yes the sprocket corners are very good.
The tank will be made of 1.5mm steel, I cant weld aluminium.

Yes I'll have a three pedal design:
Clutch (Hydraulic), Double Brake, Gas Pedal

I'll put two zylinders in one pedalbox when pressing the pedal I'll brake front and rear Wheels. (Corey never heard about such adapters/balancers thanks)
With the a hydraulik handbrake I can brake rear separately.

Thats enough for me I think.

Awesome progress mate!!!

Are you machining those parts yourself?

With the extra bolts for the sprocket, are you going to weld the ring onto the centre hub? Because (unless there's something I cant see...) otherwise it won't actually be helping with the load, it will just be extra weight.

Keep the updates coming!

Cheers

A company in our town has made these parts.
I cant do such complex things with my old lathe.

I think i will drill and tap 6 holes in the gap of these 2 rings. Then they will be bolted together. Like a modern motorbike sprocket.

Oh yeah that's fair enough.

So does that mean there will be 18 bolts holding the sprocket on? Or am I confused lol
