Hi Cisco
Its not mine. Belongs to Barry (aus4) It fits the purpose for us as we have 460k round trip each fortnight to sail. Ron, please post some pics of your steering.
Cheers
Vic
OK! Here's the deal.
Please read what I have to say in this post prior to Reply.
It should be understood that the Bicycle Steering Head/Fork section has been fitted with a solid steel Rod, a High Carbon heavy walled Tube will do the same job, if solid a central hole has to be drilled into the top end to take any excess steering tube Bolt the Handle Bar Locking section should be set in the Fork Tube for the minimal amount of metal needed to lock it firmly and SAFELY in place and from the fork end measured up to its base giving the maximum amount of solid Rod/Tube to be had for reinforcing of the forks.
There that should be as Clear as Mud.
The Quadrant, to me, is a logical size to give maximum travel and ease of operation i.e. best leverage. At it's current size it can be swiftly slapped over for sharp turns for minimum effort. The Pulleys cam from the bottom end of a Wind Surfer Sail, triple Block, they are Deep Groove Sheave. I believe they will have less tendency to allow the Cables to jump off. The bushings were a central cheek holder with a over fitted Axle Bush, this I used as a fixed bush over the retaining Bolts with the Sheaves running on them. The Foot Peddle is fitted onto a Chassis Mounted Box Section/ Square RHS tube to allow Leg Length Adjustment for shorter operators.
When the local Sail Maker goes back to work I will upgrade what you see serving as Cable. This will be SS Rigging Cable Plastic Coated. The Peddle to Cable Connection will be via 2 Heavy Trampoline style Springs to maintain tension on the steering cables at all times. The ends of which will be as long as required to fit the shortest leg length and held in place by Cable Clamps to allow adjustment and tension setting.
Thank Christ for that.. They've gone. Not much else I can add without being directly Q'ed
Ron
This morning was quite calm when the wife and girls went out for the day. I told them ,Halfheartedly, that I would enjoy a bit of a shot on the Airport. HA! the Breeze started to get up and so to my excitement. I loaded Occum's Razor into the Ute had a Piece of chicken and a couple of Black JB's and made the off.
. The Breeze was just that a Light Breeze which I thought I may get a little bit of movement out off
. Out came the Razor and I quickly assembled it and settled into the Capsule. Damn! I could sleep very comfortably in that thing. And so the saga of two hrs of strengthening breeze given especially to me for the enjoyment there of. Yes I say to me as it most certainly looked like it wasn't going to happen until I asked for to come. Yeah! So now I hear you saying "The Man is a Nutter" Anyways there was a settling in period where I just pottered about and as the wind got between 10 -12Kts I started to experiment with OR. It seems to me that the wind was better in some parts of the Tarmac than others and I finished tearing down the strip around the Gravel Heaps and doing a few sort of hops and judders until in the end I could get speed enough to go into full Broadsides "With Squealing Rubber". Those aircraft tires certainly handle rough treatment.[}:)][}:)]. On one occasion the Razor "Bolted Clean Away" I know it wasn't standing still, that is for certs. I think about 40 Clicks and it scared the Bejesus out of me so I swung her about and misjudged the turn and finished up Screaming with laughter and half way up a 140Cm Heap of Gravel
No I kid you not I will have to get some sort of Speedo on that thing because I started to run the 150mtr strip at a damned good pace and only having a couple of inches clearance between my Butt and the Bitumen does get a little disconcerting but running up that heap and having the Front End pointing at the sky and my rear wheels trying to climb as well was the funniest thing to experience for a second I thought I was going to launch myself. I am still trying to get Jenni' to come take a few pic's of OR in Full Flight. From my Supine position the Mast Has a lovely sideways Curve to it and the Sail is Full and Smooth and it seems the Harder it is Sheeted Down the Faster the Razor runs. Yep! She lifts her Skirts and Runs Like the Wind and the closer to the wind the faster she wants to run.
Ron
PS. In all providence supplied me with almost exactly 2 hrs of Breezes before I had to give it way and go home.
As luck would have it a friend came over to see me Crash Tricked him, Didn't I? Anyway he shots of Occum's Razor's Shakedown.
I managed to Break a couple of inches from the mast bottom and one of those Aluminum Sail Board Extension Tubes. Not a pretty sight
How do I go about uploading WMV Movie footage 
Ron
for the movie , upload to UTUBE the post the link.
what we have learned today is that although a windsurfer mast with windsurfer extension tube as a stiffener works fine as a base for a LLM, it doesnt look like it is really strong enough for a class5 size yacht.
experiment possibly conclusive
i would like to see a close up of the before as I dont know what that SS part and bolt is for
Dam, I did the same thing when I tried a windsurfer mast on aus230,I had a aluminum insert to,snapped like a carrot, suggest beefing it up with a wood insert.
Neb's/Nebo',
Nope. That would weaken the Mast.
Aus, Please note that the Extension broke at the first hole above the Mast Seat. All the stress that came too it was directly on the Aluminum and it had NO reinforcing so in reality It did really well considering the Forces that came against it.
When it broke it only took 2" of the Base with it, very lucky really.
Landyacht, [}:)][}:)] Now L'y you should know better than to ask of an experimenter what he is keeping as a secret weapon.
Well from what I see of Land Yacht Class 5 mast and Steps is that they tend to Lay against a bolt to support them at the angle required. That to me is a very nasty pressure point. So let us just call that part a "Upper Mast Support
and Retainer Bolt". Now how is that for a Convoluted Handle
I shall now go take some pic's. Hang on a Tick.
Thanks for the Upload Tip. Both yourself and Vic have been very helpful.
At this point I think I should "Thank" of the membership that have offered advice and encouragement over this lot of builds. Believe me it is much appreciated. Thanks Guys.

Well So much for you tube. First I try to set up you tube account, then I have to set up a further account with Google only to be told that I do not exist in gmail. Hells Bells! I know that already nor will I I am not asked to create a Password so I can't log in any where. Like most of these prog's, Face Book, Twitter etc they are bulls**t info gatherers, so I suppose you will have to make do with the odd still and be happy with that small mercy.
Ron
To add a little more info to the use of Carbon Fiber and probably any Fiber type material Masts. I would suggest strongly that Windsurfer Mast Extensions should not be used for anything but raising the mast 25 or 50 mm. Definitely NO More. They can be used, I should think. For use as strengthening the base of the Mast, for the length of the Extension. However I think if you feel the mast should be reinforced a piece of a broken mast around 750mm to 1mtr even longer is the way to go. At the Base of a Carbon or Glass Mast some strengthening should be used against Tube Collapse should be used. Even though these materials are very strong and do not fail slowly. They either have integrity or they do not. Personally I like to Over Engineer these things as the little extra added weight is worthwhile as against a Catastrophic Collapse. That would be real fun on a Stinking Hot Salt or Clay Pan.
Ron
PS, Those Scooter Wheels look nice. There is another Scooter around with Wheels around the 16"/400mm mark I have seen down here and had the same thinking Gizmo
we dont normally use the extensions as extensions Nikrum , we fully insert them.
get one as long as possible and put it in a round section mast step( eg LLM) not a tapered set up. experiment done long ago , fail confirmed.
those scooter wheels do look nice, but being scooter wheels they are too heavy, and the tyres wont give that good a ride, again too heavy, but would feel nice on some nice smooth tarmac
The extensions may be OK on a windsurfer, But I have busted several on my old windflyer and one on the mini and another on aus230. If you need extensions put it on top of the mast and use a internal stiffener (wood or Thick aluminum tube) in the base of the mast it saves a lot of heart ache.
Cheers
aus230
Typical! Shut the Gate after the Bull has escaped.. Lucky I didn't get pregnant! .
Yep! Now there is a lesson well learned. I should have known better.
I have/had some extra pieces of Mast sections and I have strong doubts that the mast will bust again. If you take note of the busted extension and the Mast Step Rest. You will see exactly what happened and why. Post; Posted - 12/01/2011 : 7:42 am pic's will explain what I have done to gain a little extra permanent mast length and reinforcing at the same time. I guess I should mention and not loose sight of the fact that this particular Mast is built up of 3 or 4 broken mast pieces and was more as an experimental trial before shortening my 5.5mtr Spare .
Ron
I have just been into the Events and Comps Page. Great Stuff. I also noted the steering mechanisms being used.. Suffice to say I haven't made a bad choice for the Razor.
Ron
I took OR out to Peggs today. Typical, When we were going up the coast a few K's short of Pegg's the waves were showing some nice white caps and by the time I got into OR it was dropping and becoming gusty! What is that Crap.
I go fishing and when I arrive there is a nice ripple on the water and by the time I get my gear on and in the water the wind has dropped,Swung or increased to the point that the Fly Line is standing parallel to the water!!! London to a Brick on if I went to Lake Lefroy you guys would be have a ton of fun until I turned up then you would either be becalmed in the middle of the Salt Pan or blown clear across the other side... Damn!
Anyway I got a few bursts to settle me down and then my mates wife thought she would like a go.. Hey! Not a problem. Set her up a few brief instructions and start her moving and Wham! She bleeding SHOT through like she had a Bull after her and I will grant her this she kept her head and did a few turns and managed to slow down and get back near her spectators and her expression was total surprise and "Bloody Hell! It is Fast" and she cruised on by having a load of fun and she managed to lift a wheel in gusts.
Hopefully there will be a few dood pic's to post on the Web soon.
Ron
I just thought I'd upload these for a couple of comments from those more experienced than I.
I had OR out on the Tarmac yesterday arvo. Winds 5 gusting to 6 on the Beaufort Scale. It did get very interesting at times, very interesting indeed. I near to had to use the Toilet paper we keep in the car for emergencies . I would dearly love to know what the beast was doing but she was still accelerating towards the 8' Chain Mesh security fence, haul the sail in and steering away with squealing tires. This happened a couple of times. What I did really like is when the gusts the Mast bent really nicely then released the pent up power allowing me a warning and time to react to a wheel lifting. The acceleration was another thing that I was astounded by. I could feel the thing lift her skirts and RUN. Suspension? Well I would recommend Carbon Fiber Axles on a "Y" Frame, I am running around 40PSI in the Rear Aircraft tires and 30 - 40 in the front and the ride is by no means rouge. That is absorbed by the CF axles, they also take a bit of the sting out of sudden gusts of wind. It would be really nice if I could Run Occum's Razor the full length of the Airstrip on a windy day
Ron
Looks like that machine of yours is going well Ron
Good to see you are having fun with it
Is that the Nut in the background ?
I climbed over that lump some years ago
By George HIKO there's no putting one over you lad, is there? It surely is the Nut from Pegg's Beach not to far from Port Latta.
From what you see of the Mast and Sail, do they look ok?? Not looking for compliments or the like. If there is a problem just say so.
Ron
Looks good, my only suggestion is move the black pulley [last in the rope before it gets to your hands] forward perhaps above your ankles rather than your knees, that way you it wont end up pulley to pulley like in one pic.
Ditto to that Looks good to me Ron
You will gradually change things in a small way to suit yourself as time goes on if you are anything like me but you can be proud of your efforts
Well done mate!
Thanks Giz'.
Yes it is a bit of a pain. The system is 2 single sheave Blocks one with a secondary loop to tie of the Down-haul Rope End the other end of the rope is tied off on the Down-haul Block which the Sheet passes through. When first rigged the Sail has not been stretched, the stretching allows the Down-haul Pulley to close with the Sheet Blocks, "Choker Block". This is adjusted latter on when the Sail has stretched enough.
At some point the stretching etc allows the 2 smaller Pulleys in the Down-haul system to become "Choker Block". For the uninitiated Choker Block refers to the situation where the pulleys in a rigging system close/jam together and no longer operate for the purpose rigged. Most terms,such as this: Choker Block, Brass Monkey, Box and Screw, Devils Windlass are born out of Navel and Black Smith-ing development of the equipment. Freezing the Balls of a Monkey was a very real problem until Brass was used then if it were cold enough to Freeze them from a Brass Monkey it was very cold indeedOther problems alleviated by the usage Brass in the construction of a Brass Monkey was the Balls not rusting themselves together and to the Monkey. So endeth today's lesson
Ron
PS. HIKO yours just came in. Thank you I was looking for Critical comment but a Pat on the Back also goes down a treat.
Ron, if you slide your top pulley blocks forward on your boom, you can remove the downhaul and pull the whole sail down with your sheet rope, stretching the sail evenly. To help spread the load on the boom, separate the top pulleys. Doing this will allow the pulleys to interlock and pull the boom lower. Even with the sail sheeted right in you can still push the boom into the wind to point a little more into the wind.(takes a bit of upper body strength and improves upper body strength). Hey! Exercise while having fun1
Great looking yacht Ron. The guys' comments on sheeting are right on as you can see a fair bit of flex in the boom.
I especially like your wheel combination. Recycled aero tyres for the rear is the go.
They will cop a hell of a flogging by the looks of your skid marks.
Lucky you did not get any of them in your pants.
Cisco
I wouldn't be too sure about that. There were a couple of when the Old Sphincter tried to chew its way through the seat. It didn't feel to much like fun when there was a conflict between Upwind Wheel Lift and Power Slide.
Yes. I think that the Aircraft Tires are certainly the go; Cheap as Chips, Tough as nails, Sound good in a Power Slide and loads of other features. I think the Low Dia' would be tougher then the Glass Home Made (I'm not knocking them) Wheels for my application as they are probably able to take HOONING better, especially on Tarmac and gravel.
It would be great if any of you guys where coming to Tassie in the not too distant future to swing by Wynyard for a test run of Occum's Razor. We could probably dig up a Bed for a night or 2, mind you pitching where tucker is concerned would be appreciated.
Ron
Well, talking about and "Skid Marks" and "Sphincter Contractions", the hairiest one I have had was at the Elliot Heads Esplanade.
It has a really noice concrete path (whether it is a foot path or a blokart path is the debate) which is maybe 3 or 400 mm wider than the blokart wheel base.
My first time at this spot and the wind was blowin' noice too, about 20 k.?
Parked Francis Fairmont (or the Silver Streak if you like) in the top end car park, emptied her boot and rigged the jig pointed into the wind which was coming from a little bit south of east ie ESE. Pretty perfect for one direction and workable for the other.
Direction I would be sailing on the first leg was a slightly windey route north as we can't let the joggers and dog walkers get bored can we?
So, secured the car, mounted the rig, pulled the sheet and it just took off. I'm hurling along having a ball when the front wheel starts jumping off the path because the mast is hitting the overhanging branches of the She Oaks planted next to the path.
Look up. OK dodge the trees by dropping the right wheel off the path and I am still hooting.
Next thing the ground drops away for a gully which is crossed by the concrete path I am on. However the crossing has posts and rails for the frail on it.
Heading for this at least 45 kmh does not allow the feint hearted time for indecision. Instant "Go for It". Rather bust a couple of wheels off than bust me 'ead.
I am still here and so are the wheels.
Statutory Warning:- "Do not try this at home or anywhere else."
P.S. The effects have worn off but I still get a tremble when I think about it.
I forgot to mention. I have another sail on the move and soon to come. It is/was an 11mtr Windsurfer Speed Sail with Cams, Stiff Tubular Battens and a1mtr wide head. It has now been cut down to about 7sqm. The foot is a bit shorter than the current Neil Pryde Sail allowing a deal more meterage in the head area.

The above image if you can imagine it less the bottom batten panel is a goo approximation.
Any takers on how this may perform??? It would be nice to have an idea of what to expect from it.
Ron
I reckon it would make a good light wind sail. Plenty of power up top. If the wind comes up while sailing, you may become the first lanyachter to do a 360 degree sideways flip [}:)]
