That is spot on Joe.
If you heat the arm and bend it at the axle attachment point it will be even stronger. (without the right angle tab at the end trying to twist it)

I think a bell-crank system may be needed like this. (BUT only if you cant get you head round an aircraft rudder steering system, push right and go right......... like "landyacht" failed at , while piloting my yacht).




This looks perfect Chook. I'm sure you also meant to draw 2 separate steering links that attach to the bellcrank instead of the single one pictured (like the original quad was) That will allow for suspension travel up and down etc.....

Gibber, if you should want the airplane type steering, just reverse the bellcrank's pivot from front to aft of the steering links.

Yes that's a very good point. Separate tie-rods for sure. I was too focused on positioning the pivot points.

One of my Agricultural students did the drawing for me, as the original was drawn on the back of my lunch wrapper and involved lots of pivoting hand movements to get him to understand my rough plan.

I'm not sure, but I think that might bind because the rods are not parallel (or at least it looks that way). Might want to consider a single push/pull rod.

Looks a lot better than the wrapper; how did he do it? I've thought about getting a simple drawing program but never did. Are they easy to work?

So cut the forward pivot paten out of masonite as it was available, will be actually be made from allunimium plate 6mm.
Pivot points will be 20/25 mm steel verticle posts fixed thru appropriate id pipe on steel fixing brackets
The push pullrods from the foot operating panel 16mm round with appropriate ends. Appears as flat slats 40mm
the foot operarion bar will be steel it appears in photo as masonite. basically only in two dimension.
3dimension will take into account actual height differences, there should be no grabbing
Steering tyerods ulluminium.......hope that all makes sence, obvious unforseen problems overcom as encounted
P.S. it was my first time on cut out bandsaw...and i wandered a bit.....could/should have cut better

The local High School uses "Google sketchup"

www.sketchup.com/
It's free as a student and to the general public. A very powerful program if you learn it.

I have a very basic understanding of it, but just don't dedicate enough time to it to get really competent with it.
The students are "jets" on it though and flick diagrams out in minutes.
I could actually build stuff quicker than drawing it in a CAD program I'm so slow.

Also the foot control bar could be straight with a central hole (pivot not offset as drawn) just have a centre pivot and the control rod mounted directly off it at a point out from the pivot that gives you "lock to lock" steering control Joe.

With the two control rods "a pull/pull system" a much lighter rod could be used or even cable.

you picked out what i would do chook on the kick bar, the push rods could be lighter as you eluded to, i have 12mm rod too.
basically i have a working model that will between , the drawing, the cut out, and the final production will be tweeked, to a workable unit.

have to pick all my rear end machining today from my machining shop, they rang yesterday and said "all ready". Looking forward

probably 2 mths to trials time, shorter than that will post some photos. very wet looking day here today , will interupt outdoor work.

I have a better, more positive feeeling of successful completion , more than most polititions at this place and time

front pivot point for foot steer about to be installed. half inch bolt with half n old plastic wheel to act as turn table for 6mm thick front plate that will connect tye rods and push rods. Weather a bit of a bugbear for outside work at this time. All my rearend bits are at hand to assemble and install weather permiting. Little jobs get done at night on my drafting bench.....thats just how it is......

Hey Gibber!!! That's fantastic mate.
My father and also my brother have 9G tractors and have trekked all over Australia raising money for the Royal Flying Doctor Service.
Old Jim has clocked up 38,000kms since it was fully restored. This is in my father's shed all sorts of goodies there. Everything in the shed runs and can be put to work from a 49 Holden a 1923 T model car, a 1920 "Twin City" tractor (4 cylinder, twin cam 4 overhead valves per cylinder.......... See it's not a new thing.)




Chamberlain tractors are a passion of ours. I grew up wearing em out and my Dad spends every waking hour restoring gear. He has 19 tractors, 6 vintage cars along with 11 motorbikes, over 80 stationary motors and god knows how many tools.

This is a 100hp open crankshaft Crossley that came out of the Higginsville Pumping station. It's brother is behind it and came from Widgiemooltha Pumping station. Governed operating speed is 235 rpm.
The flywheels are 8 feet across and the motor as it sits on it's frame weighs 12 tons. It can be shifted by lifting it hydraulically onto it's wheels and then towed around. They are compressed air start at 250psi.

60hp Rushton from the power house in Wiluna. You can see the hydraulic power pack for lifting them onto their wheels

One for you Vic. The old Norseman ambulance complete with the stretcher still inside mate. It runs like a clock.




A T model truck with steel drive wheels like the old tractors, with ground drive super spreader which is driven from the drive chains using a T model diff to drive the spinner.



Lots of other treasures too.

" WOW " chook2, i can now understand the knowledge of your words, after seeing into your boyhood alladins cave. Would have to be very near top tent in -aussie?, no maybe, world wide, thanks for the photos, and commentory. It may be time to run a thread on sheds ( not a competition ) in landyachting ? Someone has to do it. eventually !

well some photos to show where i,m at of today. Unfortunately will be unable to meet the anticipated completion date to be ready for lake lefroy this year, so it will be next year . I think it will take a other 2 mths min, 4 mths max. Thats how it is, so some photos of steering and rear wheel suspension and hand brake set up with the male (BMI) model pozing as T P 3..? QUATERMASTER DAVE.













about another six to come.......l

with 6 small diameter wheels that must cause a lot of drag, do you have a large rig to get it rolling?

the wòod is pine stained dark and placed under the steering arms to mitagate vibration. As to the ability to move from dead stop in very light breeze, dosent seem to be a problem, but one would not expect it to be as agile as a LLM, it wasnt made for that . It is made to run long distances on rural secondary tracks with comfort and control.....
basically only front end left to finish, then rigging, then test run trials......

pretty sure will be at Kingston from about 19th to 28th jan 2017.

would love to give my landyacht chassi a try out with kite power, recon it would be suitable, two up, one control steering

other kite flying.

if anyone is interested and has the gear needed, let me know. I will rig up a secondary seat over top of steering rods,

also a attachment point for kite where mast would stand ( remove mast ). some photos of recommended attachment

would be appreciated.

tell me of any other points needed maybe an explanitory photo too.

photos in above box is where im at....gibba

No need for a kite attachment point, that's what the second person is for! I'm sure there will be someone at Kingston that will want to try your experiment
