Just working out a build

Congratulations on getting the cat up and rolling!

looks real good to me (bad case of airstrip envy developing here...)

as for Schrodingers cat- the "big bang theory" has an explanation on youtube that works!

Well done Ron, SC looks great (dead or alive)! The carbon seems pretty stiff too, can't make out much 'sagging' despite your lightweight 100kg frame. Hope it all holds together, which I'm confident it will.

Thank you, thank you, thank you all Accolades will be graciously accepted[}:)]

It is very pleasing to do something for the first time and from unconventional materials. To have it all hold together for at least one ride, let alone around 5 hours work. I think I stated earlier that time will show all and test all. Considering the tremendous stresses that would be had at the Mast Step Joint I am surprised that it hasn't cracked up. I tested SC quite heavily, forcing it to slide side ways and pulling it heavily into and across wind generating as much pressure as I could in the wind available and dare say that when it lifted a wheel that it could have gone onto its side. I loosened the sheet to keep her right side up. In the early stages of testing there was a little creaking and groaning which settled down. To repeat myself again "Time will tell".

Tires are now the next thing, getting replacements.. The Hardware and Garden Shops are only too willing to sell you the Barrow but the spares etc.

Dave, if I ever get "She whom must be obeyed" to come and take some pic's of the sail and Carbon under proper wind stress you may change your mind. Even though the Spine is double thickness (1 x Helical wound and 1 x Parallel laid) it still torque winds fairly well.

It is funny/odd/strange, but I thought those names would naturally strike a little curiosity. I personally like them as they piqued my curiosity as an un-educated person. To cause no comment at all (Without probing)struck me as a little odd which only served to get my curiosity up again and make me wonder "Are these guys all well educated and "Full Bottle?" or are they just not "Curios"?". If the latter is the case then how come they are "Land Sailors" Hmmm! Curiouser and curiouser.

Sorry test pilot1, I prefer to Dogpile.
Don't like Googling only use Google Earth.

Anyways I found them used in a book by Stephen Hawking "A brief history of Time". I tried to read "The nature of space and time "
In the first one there was much I couldn't get a handle on but then there was a lot that I could. The second?? Well I don't want to go there..


Mind you knowing the ideas behind those names I figured they were apt for my constructions.
Ron

Ah! 'twas he whom made me realize that "All is as it should be in the Universe". However when it is all boiled down all the Boffins do is to take Common Sense and convert it to numbers and symbols (Mathematically Quantify) to find a Theorem that will describe it all. Ih! Maybe, maybe not. There is one hell uv a lot of info out there to deal with.

I suspect that Hawking and Co's String Theory is as close as they will get short of traveling into a Naked Singularity. I can tell you this much "It ain't gonna be me that travels there--------------------------------Least ways not in this life time

Given the latest info I wonder how hot that Big Bang Material was just prior to Decompression???? The Strings is Hot little buggers.

When you're on two wheels toe-in disappears so maybe mak a two wheeled landyacht?

Just a thought here, is the plastic of the hub exactly true? If the surface you're truing against isn't exactly 90 degrees to the hub then that might do it. Also perhaps try rolling the wheel 180 degrees so that what was on the bottom is now the top and see how the toe lines up?

For a quick test I'd roll out two lengths of christmas wrapping paper on the ground (it's the season after all), and roll the yacht along these lengths. If they start moving outwards then you know you've got toe-in

Its interesting that someone else has questioned the Rear Wheel Alignment and how its done and how can it be checked?, I asked the same question a long time and there seemed to be no finite convincing way of doing it. [all i seemed to get is "It was correct when it was made" or we have a "jig to test it"]
I at one stage spent about an hour or so talking to an Australian paralympian about the wheels on marathon racing wheel chairs, he made the comment that alignment was SUPER CRITICAL and over the marathon distances they do, even a very small error added up to a lot of energy wasted.
With that comment in my mind any slight bump, twist, gust of wind, or movement of pilot weight WILL change the alignment on a Y frame land yacht !!!! and if you did find a way of definitively testing the alignment it would need to be done with a fully rigged yacht and the pilot in the yacht.

Ok! It sounds like the Old Aussie adage "Near Enough (is good enough)" seems to hold true. Funny thing is I fitted the 6X6 Edwards Rims, Axle Stubs and Axles to Occum's Razor and took several hours (With the Flue, it entered every damaged part of me and I'm am just about crippled at the moment, Lower Spine)

I got it very near to exact and everything firm fitting. I pulled it apart and fitted permanent Fixings and put it back together and BUGGER it has a Toe out of about 4.5" over 6 mtrs. Oh well. Nothing can be done about it now.
Mind you I loaded OR up with my 100kgs and it didn't change 1mm. The Lazar Just tilted upwards. Further Tests tomorrow as I now have the Air Tracks fitted and had a little roll down the drive way. Feels nice and Cozy

Am I looking at this right but it looks as though you have a mega amount of trail
on the steering ? If it is as I think it will tend to turn you off to leeward I imagine
The pivot line of the steering should meet a verticle line through the axle of the front wheel right on the point where it touches the ground or very close to it

Not only will it fix steering and toe out it will level the spine and stand the mast up closer to verticle

Please do not take notice to the Front Wheel Rig, "It Ain't Necessarily So" (Where does that Crap come from?


The above was part of that post!! Damn It All!! You three can consider yourselves BITCH Slapped!! Now Go back and read my WORDS!! Do you know what words are???(*&%%$.
Either that or you are conspiring to get me going......... Well congratulations! You managed that quite easily.

Mind you, you just reminded me, that Wheel was not on it when I did the alignment. SOB! What ever gets your rocks off. I'll wear it this time..
Ron

HIKO,
You're forgiven. Don't worry, Based on your Dad's saying I must be the greatest fool of all. Tell him he is Bitch Slapped and all. The saying also has a close relative. In a Court Room it is said a person who acts as both Lawyer and Client has a Fool for a client..

I have to admit that threads that you guys put forward certainly made me look back at how I set the whole thing up and stopped me from Racing into a premature correction. Just imagine, had I gone to it and pulled the Axles apart and Reset the Axle Stubs then when my new Front Wheel arrived I set it up as I want it.. The Toe in would have been horrendous . Not that funny realy if you are the one haveing to reverse you mistake but from the outside looking in it would have been a really good Cack.
Ron

Perhaps wheel alignment needs a thread of it's own!
I reckon the reason this has not been resolved, is because there is no "right answer". The Glen 5 I sailed in Europe was best when set loaded and static, sheet pulled in etc with 1 metre of toe in over 3 km sighting distance. We had a pair of telescopic rifle sights which rested against the wheels, with exceptionally accurate legs to ensure they were level. The wheels had 20 degrees of lean in at the top. The next version of the Glen was totally hopeles with the same alignment, and ran much the same toe out to work. The Seagull Quebec was nearly parallel, the Fed 5 needed considerable toe out to work. The YOTT needed even more toe out.
My class 3 in the avatar was set parallel when the plank was level. As it was set up for both the front plank and rear to flex so the yacht stayed as level as possible under flex/load this seemed to work.
Harking back to the beginning, there is (in my opinion) no right answer.

Well so far KIWI 307 seems to be the only one to, in a roundabout way, think as I do; "Near enough is good enough", in this case or " It's as near as "Damn It" is to Swearing. Anyway once again I've come to a screaming stop, waiting for my Front Rim to arrive. Then I can go about setting up the Front End and steering.[}:)][}:)]

Looking at your Rig CLEMCO I think I may be able to do something similar with OR's Steering. However I won't know until I get a Front End on the deck and doing it's thing. As for SC and my sailing prowess, I think the feet reach the job and perform adequately. It is all information not to be sneered at and to be used where appropriate.
I also agree with the dedicated Thread Idea and no I'm not going to be the patsy to do it.. I do not have the knowledge in this one
