Typical Young Bucks, the Filthy Little Buggers...[}:)] I seem to remember something about that but it was so long ago now. It was hard to get the mind above the Belt Buckle
Usually those Flanged Bearings are of poor quality as they don't have to run at High Speed. I have been told that they are designed to allow them to be flushed of Concrete and sand etc, I know the Chinese ones Crap Out really quickly.
The Bearings are easily replaced with High quality Sealed Bearings that have been designed to take a degree of side thrust but must be fitted the right way around.
Look inside the Axle Cavity with the bearings removed (Easily Tapped from the Rim. The Bearing Seat should be recessed into the cavity stepping out to the Bearing Seat. I most certainly hope so. Chinese Wheels rely totally on the Bearing Flange to control their movement where as Fallshaw (I believe) are recessed to take a better quality Bearing, however one should use a Spacer on the Axle itself to stop over tightening from affecting the Plastic seat. The Spacer should be around.5mm longer than the distance between the distance between the Outer Race side faces. Now there Mud should be clearer than that. Short of that I can not make it clearer without Sketches.

Jess and Bodie.......time for helmets and seat belts!
The steering was quite ok........might be different when under load with full sail and a strong following breeze.
A big thanks to Bodie's dad for the hydraulic hose...way to go!
Good thing we only had a small hill!!!
Here are a few photos I took in sequence this morning
Even without sails it was awesome fun
I wonder what would happen if Joeden rammed into Pato's LandRover haha - it would not be pretty
Ok, it sounds fine to me to run with the 3mm washer each side and the plates on the inside the forks.
If you are happy with this I'll do it in the morning for you.
I will make up 2 longer spacers (one for each side) as well for you.
So when you do upgrade to, 2 x 6004 bearings and the plastic adapters you will be able to slip these longer spacers in each side and get straight back to sailing again.
Question Ron?
If you had a stud threaded into each side of the axle and removed only the nut each time the wheel is taken off, you must have a slotted plate on the forks to remove the wheel?????? Am I right or have I just lost the plot.
Geez my old mellon is hurting now.
Looks like you guys are havin' a ball from the pics!!!!.
No shortage of hills there I've heard.
My old man toured Tassi, a few years ago and reckons it would be the "largest state
in Australia", if they flattened the bugger out.
Cheers
Hi Danny
This sounds great
I'll go into the local bearing shop with a few pics of what we are up to......may put them right off!!!
Will take my Mum's old Bernina sewing machine in tomorrow......the school's machine blew up....Will have to shorten the leech of two sails......don't think we will try to make them flatter at this stage. I'm thinking this rig would be best for reaching and a more powerful sail would be better suited to the slower speeds expected on our school oval as we move into wet winter conditions.
The troops are really keen to get to a big beach.......as am I. Will have to sort out any problems before that.
The Fallshaw wheel will lower the front of the machine.....pity as the rear steering pedals are pretty low to the ground already!
We are going to enclose the cockpit in coreflute.......will stop feet dragging underneath.....hopefully.
Once again....thank's for your support!
Cheers Nick
What is it with Tassies and this thinking that Hobart to Burnie is a long trip?? "All the way up to Oldina" ???? 10k's away? All the way?? Youd die if you drove across the Nullarbor or down from Darwin.. There is a lovely Camping Ground at Pegg's Beach.
In answer to Chook, yes I used the Forks of a BMX on one of my machines and that system on the Razor.
If you guys are over this way on a Holliday give us a hoy and arrangements could be made for a Van or a bed for a few nights.
Ron
Dang...Paul
All 6
wheels are at school....first time! Will check that out in the morning.
The deal with the nice seats went pear shaped.......was going to cost way too much to get them here. Desertyank gave us a very nice cash donation instead.
Need to find out if any of these are still available in Oziland.......keeping in mind they are banned for use in competition stock cars.
The black one is very, very suitable for what we are up to. The red one is very heavy and not as comfortable.
Does anybody out there know what they are called?
Any hiding in a shed somewhere?.......We now have a bit of cash to buy some.
Hi Paul
Sorry aboout the crappy pic
Bearing diam. outside about 50.8 ish mm
Inside diam. 25
Plastic insert brings it down to 20mm
Bearing housing depth is about 13mm...width 50mm
Cheers Nick
Hey guys!
Well the MAD-hatten project is coming together. We have been working really hard and we nearly have a finished project. There is a few other changes we have to make, ect. The new front wheel and axel, Which Chook2 is kindly hepling us with! Thankyou! We also need to cut some sails down to the right size, ( this will be an interesting job!) And once all thats done were ready to sail. We are really looking forward to this and we will make sure we post heaps of pictures and videos for all to view! We have been using the yacht as a billy cart to test the handling and strenght so far its looking really really good! We have a good hill to take it down and its a lot of fun. One difference from using a normal land yacht when your sitting in the front of this yacht you have no control of the steering, so you have to trust the person in the back which has all the controll! There also has been lots of screaming from the person in the front!! I have a good pic for you!
Tassiefubar,
Damn! I am impressed with your teaching methods. Good Ol' Common Sense /Nouse and Hands On. Great Stuff, it will stick with them for a Life Time.
I am still hunting for a site I stumbled on and then lost. It is a Bearing Sales place in the States that also could cut a Groove in the Outer Race to take a Retainer Clip, this would be lovely for replacing Cheap Barrow Bearings with High Quality Bearings.
Ron
These are the seats we are looking for, the red one is quite heavy and not very comfortable. But the black one is very light and comfortable, if anyone no's were we can pick some of these up from Austrlalia wide would be best please POST!!! Thanks Guys!!!
Tassiefubar,
Just looking through the pic's I noticed that the Steering Bar is only cut at the ends and has no slip prevention welded to it.. Ie. a pair of large washers or pieces of scrap metal welded over the ends. Nothing too large of fancy just enough to prevent the feet from slipping off of the end when they are moist.
The pic's are great and everyone seems to be having a Ball, nice to see
Ron
There are probably a few of you who wonder how good the steering is on our "MADHATTEN" LandYacht. Well today we had a test run in the schools gym. I took a few videos and uploaded it here:
quite a wide steering circle. having seen it moving , I would be inclined to shorten the yacht by as much as 500mm. possibly more maybe even 1000mm.
this will substantially reduce the fatal twist that the yacht will probably suffer once sails are fitted. the effect of the sails twisting the chassis will be significantly worse when sailing on "slow", high drag surfaces like the grass you are sailing on.
sudden turns like the lads seem to want to do will make it worse still.
something to think about[}:)] the front passenger could move back to that crossbar assembly too
Me thinks you are right Paul......we can snip about 1m off the thing.
Pity though, as the "SUS...pension" is really good.
We were going to have the foresail a lot smaller than the main anyway .....so we can use a much shorter boom. The slot between the 2 won't be as good but we don't want the thing to "torquesk"...and catastrophically deconstruct itself.
We could also put the main mast behind the rear seat.....perhaps even behind the axle. We could sheet this on a broken windsurfer mast section....as per the origional plan.
We do slide the front seat back to the cross member...we had it forward for Naffy.
We also thought about some extra stringers? on either side running from outboard of the rear axles to the steering head...just above floor level. Extra weight though!
Don't you just love steel.
Got the new front axles today...you ripper Thank's Chook, they look excellent.
A smaller front wheel will look pretty cool.
Have a big HPV race looming.....might have to put the Madhatten project on hold for a week or so.
Have to rebuild a trashed trike and get it competitive again.
THE MAD-HATTEN PROJECT UPDATE
We got those axles 3 days ago... thanks so much chook
We are putting the project on hold for a few weeks because of the HPV race coming up soon.
We have nearly fully constructed Kamikaze, which will be a relief
You are most welcome.
If you get stuck again give me a yell.
I'm only too happy to spin something up for your projects.
Keep those pics coming.
Out of ingorance what is a HPV. To me it's a "high pressure valve" in hydraulics, hehe.
Hi Chook
HPV's are human powered vehicles.
We have built and race two of them.
Here are some pics of "Rosie" and "Camikazi" racing at the Salamanca 6 hour.
More top fun!
We wrote "Camikazi" off last race......rolled 5 times....anad ended up a Munted Benny.
Cheers Nick
Hey hey!!!
Racing "Tadpoles" Gee I've seen it all now.
They look like interesting vehicles. Low carbon too.
Nice construction, the red nosed one looks like a Mig 15 russian fighter thats had it's wings cropped.
Hi there,
This may be a stoopid question, in the wrong forum......but we've exhausted a few lines of enquiry so here goes anyway.
I'm looking for a kiddies toy...plastic ladybird type wheelie thingie. We picked one up from a tip shop a few years back and cut it down and used it for the front end of one of our HPV's. Looked a bit like a MIG so we added a tail and went racing. The troops have had heaps of fun...but all good things come to an end and poor old "Camikazi" was totalled last race.
She had survived at least 10 complete roll overs but I think UV rays made the plastic brittle and I stupidly failed to make a fiberglass mold. Thinking that plastic ladybirds must be ubiquitous....not one has been seen since!
Has anybody got one....or know where we can find one?
Well ......have'nt found a ladybird walker toy....so we have had to run with a garbage bin lid instead.....have not decided if it looks too stoopid or not!
We are nearly ready with Camikazi and have had to rebuild a fair bit of Rosie as well.
Big race is on Sunday....troops are excited about having clip in shoes..thanks to Doug for the pedals
Back to the Madhatten project when this latest episode of madness is over....looking forward to it......bit over HPV's
Salamanca 6 Hour Race is run.....we came second...by 15 seconds!
We were 2 laps ahead with 20 mins to race and our chain came off and got jammed.....BUMMER!
We put in a super-human effort, fixed the chain but just could not quite catch them.....got beaten by a "Gun" mainland team...sob.
Well done team...we will get them at Maryborough in November.
Took the Madhatten Project along and scooted around the track before the race...created quite a stir. Typical Tassie weather....should have taken a real boat.
Dunno how to put the pic the right way up...oops!
