Thanks for that Cisco.
Of course that town is "Fungarey" it is only spelled Whangerai.
Before moving the Sheet blocks along the Boom I wanted to try that position. I had a good reason, so I thought. Off hand I can't remember what it was at the moment. Generally speaking one would use the line of least resistance or the line gravity would take, but then I've always been one for going against convention and the Rules of Engagement. You see we have been so trained to follow convention and rules and reg's that the enemy knows what we are going to do next before we do at times where as I have found that taking a calculated risk and keeping my head down gets me in the trenches with them[}:)] where I can have my evil way before they KKKnow what's hit them. Always keep the sediment on the bottom of the pool stirred up so they have trouble seeing you.

Wheels? it is great to see that at least someone say the humor in my thinking. The center-less wheel is about, some south American chap. They would be ideal for our application, a lot of problems would be solved before we even started to design a LY.

At the moment I am trying to bring in some cast 6" rims from AZUSA. I was going to get Astro's but decided they would be too narrow for the job 3". The tires I have are at least 4" wide rims. I will, however take a look at that site.

Ron

Now that was good. I like the way you think
The idea is to use stuff like that all the time. Surely they will wake up sooner or later???
True Australian-ism is long dead. The days of "A Man's word is his bond" I can't say gone as I've made it a part of my credo but it is very rare. I don't give my word lightly as once it is given I am tied by it. It is a pity something like that can not be fashionable.
Ron

Well not a serious amount when unloaded
Nice to see another that understands my sense of humor etc.
Ron

Thanks Landyacht,
OK! point ;

1. 6'x6' Rims are a problem, I am not prepared to pay, like 3to400bucks per rim.

2. Under the circumstances those tires were designed for 6'wide may well be a prerequisite as the aircraft would use them to their maximum weight under rough touch down, I doubt that I will take them anywhere near those parameters also consider strong cross wind touchdown and side ways bounce in those conditions. In motor vehicle tire fitting we used to consider 1" +- of recommended size quite safe. These aircraft tires are also designed to take higher air pressures than wheel barrow tires and run at far greater speeds I doubt that I will make anywhere near 120MPH, that is unless I take her out in a Cyclone he he he hiyuk. Were I stupid enough to do a thing like that then I would imagine I would suffer my "Just Desserts". Don't you?? I also think that running 4" may give me a bit more rolling diameter under greater tire pressures. I think it will be safe enough but you will be the first to know if it isn't. No second, I will be the first

I am about to give you the reasoning behind the Sheet angle on Schrodinger's Cat and as per usual I treat this Forum as I usually do--------- "A place for open and frank discussion" on our Sport. I believe it is not a place to be offended unless of course a "Discuss-er/Threader becomes Offensive and or abusive and then there ways of removing that person from the scene.

Here goes nothing

I am not a great one on dynamics but my logical thought says that

" "

Direction of pull by the sheet should apply greater pressure towards the mast step coursing lesser pressure on the mast step Base while applying greater pressure towards the curving/loading of the Mast above the Boom mast intersection. 5:1 sheet ratio makes it easier for the weaker sex to operate?? May-hap I will change that at a later date.
Do not be offended anyone but consider I have never built nor operated one of these beasts before but I have used certain of the principles behind them on a lot of different rigs, ( Raising a 1500Gal tank 5mtrs onto a tank-stand then tipping it onto it's bottom up there unassisted I was told by many that I could not do this on my "Pat Malone").
To these ends I can never take the thoughts of one man as gospel but I do take his thoughts and ideas aboard and apply them where and when necessary. Hey who knows I might do something useful some day I also am using different materials and jointing methods to you guys so once again I only play by ear.

One is never to old to learn and the day I stop learning is the day I am carted off to look inside the big Furnace

Like I said I may well have the "Bull by the Horns" If so then your opposing thoughts will be listened too.
Ron

Well Gizmo you probably approve of my course method I just whacked a 1/4" drill through and a couple of Pop Rivets to hold a saddle in place.
The Prusik looks like a good hitch but then tying the blocks on starts to look a little untidy I should think.
I was told that multi sheave blocks start to have balance and binding problems so I stuck to singles where I could.

3-400 doesnt seem right, maybe $30-40 from eddies.
could somebody check that?
when you put the 6x6 tyres in a narrower rim the want to roll off the rim.
they run at the same pressures you would use for you wheelbarrow tyres.
3:1 is fine for ladies, kids, as well as us big fellas.. If they are not strong enough to pull it in then they dont have the weight to have it in , thus a balance is reached
the point I was trying to make ron is that your pulleys will be fighting agaainst themselves, ie more effort for you, with no result except needing lots of sheet rope laying in your lap when you sheet out. hauling it all in will just create a battle between the boom wanting to buckle and the boom wanting to push through the mast

Hi hope this helps I purchased 4/50 x6" wheels from attached site for my wind flyer.
cheers

Nikrum if you are a "true aussie" why not go for saw blades for wheels, that way you dont need any rubber for namby pamby vibration dampening [}:)]

Thanks LY,
May-hap I have it wrong but the boom mast thing was what I was trying to take advantage of and perhaps release a little pressure from the mast base at the spine/mast step joint
Moving the blocks is not a great hassle and I guess between you and Gizmo I am being forced to rethink my layout That's Cool.

EDDIES??? I tried to find them but came up with everything else but wheels. I have looked in aircraft sites and the wheels there were Mucho Diniero. Too rich for my pocket
and no one is prepared to crash a plane for me to benefit from there tragedy
Yep! I would hope there are a couple of SA lads that will come up with some info on eddies,,,,,,,,,,,,Like an email address or a Phone # or both would be more preferable.


Thanks for the input guys.
Ron

i went to the link that gizmo put up on this thread and emailed eddie himself , got this reply




If you have the 6” multi-purpose rim, they are available to suit 17mm, ¾ inch and 5/8 imperial. Price on these is $40.00 + GST each.



I was just wondering that if you got these 18 years ago, whether it would be a 6” multi-purpose rim or a 6” diameter x 5” wide offset go-kart rim (F120-6) If it is a go-kart rim, the price is $49.80 + GST each and they will fit a 17mm bearing.



Regards for now



Ross Edwards

EDWARDS KART WHEELS
almost the same price as 18 years ago!!!!! you want the 6" multi purpose rim to fit those tyres

Thanks for that Paul,
Whoa! I ain't a goin' there.. I don't know what I did and can't quite remember but I did go to that site and finished up god knows where and got an email back saying they didn't make that product or some such Put it down to "SOF's Disease" ( Course term, initial "F").

You have made me look like a total "Goose" for the world to see.. Ta muchly!. Most of them probably knew that anyway.

I will go there and give them a shake and see what I can make fall out of the tree..
Thanks

So Test Pilot1 I hope you are only suffering to Land Yacht Jousting[}:)][}:)]

OK! After having taken by the hand and led to Edwards Karts I managed to, All by myself, purchase a pair of General Purpose 6" x 5" Aluminum Rims and it looks like they will get here for less than $50 a piece. Now who can complain about that for a good price. Now I am dumb foundered. Someone in this country is selling a good product at a good price " Oh Wonder of wonders "Glory Be!"[}:)][}:)]

I am thinking the Air Track Tires and these Rims will not be much heavier than Barrow wheels and a little higher pressure will allow for faster running.. Anyway we will see.
Ron

Before replying to Landyacht I feer that I must report that on the 05 Day of the 12th month in the "Year of our Lord 2010" That Schrodinger's Cat was launched on the Estate section at the Western End of the Wynyard Airfield.





The wind was from a NE direction at between 5 to 10kts . Barely sufficient to move the Cat under my 100kgs but none the less the Cat managed to move me along, all be it slowly. !
I also must report that my good lady wife encouraged a Japanese visitor (Whom had never even seen a Land Yacht before she came to stay), to " 'ave a Go". Yuki immediately managed to Up Stage my efforts.. Mind you my excuse is that she is a Diminutive person probably only a little over half my weight.

SCHRODINGER'S Cat would seem to be a success.
Ron

Bloody Schrodinger's Cat. Damn It! Cisco.
I am absolutely amazed ta no one has displayed any curiosity about the names of my vehicles???? It means that either they aren't interested or they know exactly what they are So Be It.

I took SC out again this morning and it is a pity I had nobody watching with a Movie Camera. No dumby! "Nobody" is not a person..
Anyway it performed brilliantly in 10 to 15kt winds. Scrub outs, wheel of and good speed. The little beast seems to be quite squirty as well. Very pleasing indeed and nick from Peerless Industrial will be pleased to find that the Epoxy product stood up really well to the sail slapping the mast about. It will be interesting to see how long the Carbon Fiber Jointing will stand up to those stresses.
Ron.

Reply to Landyacht.
You will have to explain Planing to me, or at least the tools used to do the job.
I really am not prepared to use my Falcon 18" to do that job [}:)].
The Rim Width I have seen to and the rest is good sense.
Ron

Thank you Gentlemen.

Well then. From what I am hearing I will claim a "Worlds First" for a Carbon Bug.
That is unless someone has date and photographic evidence of an earlier one?? Dang Boys! Sure hope their ain't no one done it a fore me.

I had a heap of fun yesterday Afternoon after my "Last Post"
Schrodinger performed well in heavier gusts though the Spine does wined up pretty well. I am not sure if this is a good thing or not, it does help to keep all wheels on the deck longer even if the front wheel looks strange laying over at 6 or 7 degrees. On airport Tarmac' cheap Chinese tires don't last very long at all. After a total of about 5 hours I have had to reverse the wheels in order to wear the outside half out. The odd thing is the bicycle tire is showing little sign excess wear and it did a lot of skipping in extremely tight turns (Maxlok). When SC's sail has good wind it fills out perfectly not a ripple to be seen anywhere. Problem is getting the Boss to come out in the wind to take pic's and to top it all off my old camera has just died after 10years.
Anyway! Happy happy happy.

Hmm! Landyacht it would appear that you have at least an inkling about the names..
