The project will apreciate it so much!We will measure them up and see what we need. Again THANK YOU!!
cheers
desertyank,
Now who wouldn't accept an offer like that. It is a most generous offer and I'm buggered if it didn't bring a little tear to my old eye. to be sure it has nothing to do with me but just when I think the Human species is a lost cause someone like you comes along and makes a liar of me. More Power to you
Ron
PS; Past experience says that they could be here in 3 to 4 weeks, not long to wait, Hey??
Hey John
Our address is "Campania District High School, 2 Union Street, Campania, Tasmania (7026)"
Our phone number for Campania District High School is (03) 62604133
And the school's email is campania.district.high@education.tas.gov.au
CHDS is, again, so appreciated of what you are doing for us.
Troops are excited after the excellent response from you guys out there!
We had a build session after school in my workshop.......can you believe it, our school does NOT have a workshop!!!
Issac showed Bodie how to drill holes....hummm. Bodie said it was ..."boring!". He got a "hole" lot of experience.
These are fabricated from Duragal, the next size down from the main beam in the chassis. They "hopefully" will strengthen the area inside the beam where the seat lugs are tightened up and stop distortion.....could be interesting. We positioned them and spot welded them in place.
We also placed a similar bit inside the area where the steering pedals are located.
This facilitated a discussion on whether or not extra weight equates to an increase in speed......they were still arguing this when they went home. Me thinks we need to investigate sprint cars and high performance yachts tomorrow.
Will be fun ....I'm sure.
Oh.....we are supposed to be doing History!!!
OK, plan 'b'; I was unaware that jet fuel is $10000000000000000000000000.00 a friggin pint. The least expensive shipping i could find was $688.00 US. I could get a round trip ticket, and carry the fkrs with me for that much. thats 9 times the cost of the pair of seats....NEW!!!!!
If anyone has a suggestion that's within reason, I will still gladly donate the seats..... otherwise, Plan 'b'.....
I do actually have a plan 'b', but would rather surprise fubar (how appropriate on this occasion) ....... 
options?????
OMG!
John.....I've got a plan "Z".........How about you fly to Tassie for a holiday...bring the seats as luggage. You can stay with us and tour the island. SERIOUS
That would be cool!
Cheers Nick
Well that would see their lodgings covered both ends of the island et both Bases to work from and probably a little Fly Fishing thrown in To Boot.
Ron
When I checked out the prices at the jeggs website I was amazed at how cheap racing accessories are in the USA compared to here!
you fellas are really spoilt over there!
Do the troops win some sort of prize if they get 5000 hits on their thread?
Welding the linkages for the steering today.....cut off and end bit of an old gal rigging screw and welded it to some 15mm x .08mm chrome moly aircraft grade tube. Seemed to go quite well......though for building aircraft the don't seem to weld the stuff. Perhaps somebody could enlighten us as to why
Started on the other end and got a crappy....bubbly weld.....checked the shed for draughs etc...seem to fix the problem a bit......then it got worse......checked the gas.......seemed OK, needle in the correct position. Tried again....even worse!!! Pressed the Mig button while looking a the guage...needle dropped to zero...then rose again. Guess this is what happens when you run out of gasTRAP for stoopid player!
Got Tara and O'Sully to sit in the front seat while I manipulated the steering from the back seat, (taped at the front end with duct tape!) All seemed fine , not too heavy and got quite a nice amount of travel with the set up. Went for a bomb around the yard....the turning circle appears quite large. Is this normal for this style of steering? The bicycle set up on the other 2 yachts have really tight turning circles.
Longer wheel base therefore longer radius from rear wheels to front wheel = wider turning circle.
C'mon tassiefubar!! That is fairly basic and you are these guys teacher and I know they will be reading this.
Who gets the cane this week? The student or the teacher?? LOL
Who gets the cane this week? The student or the teacher?? LOL
Me please[}:)][}:)I love a good beating!
Crikey...STEERING....it works
Got the gas..welded the linkages together and inserted the hydraulic hose.
Went for a spin down the drive...about 800m. pretty steep in places, so got up to a fair lick of speed. NO BRAKES.
Was able to wash out a heap of speed by putting full lock on alternate sides.....steered very precisely and seems quite lite......most impressed. The poor turning circle from yesterday was the result of excess flex due to the use of duct tape....now fixed and very satisfactory.
Ended up shooting out the front gate and onto the road
Great to be back in a billy cart after a break of 40 odd (very) years.
Went for the paddock with the big hill....new local cop had a slow, lengthy gander as he drove past.... wonder what he would have thought if he got there 2 mins earlier as I shot out the gate!![}:)]
He went past twice.......have not seen a cop on that road for years.
I won't tell about the wheel coming off.....nail, instead of a split pin, jumped out
Now for the rig!!!
Oh, and some sort of BRAKES!
I bet I find that nail with the tractor tyre
Yu just gotta love bent nails and split pins, they just weren't meant for Shear Stress and if they ain't bent properly they jump out of their holes.
Damn! tassiefubar why don't you guys use Threaded Bolts and Castellate the Nut then drill the bolt strategically to suit the nut when it holds the correct tension??? That way the Pin will not be under Shear at any point, just like on a Trailer or Car front wheels.
Ron
Hi Ron
Nail was not bent!!!! just sitting there holding the thing in place....you knowWay too tempory.
The funniest bit was the axles not yet being welded in place......the wheel base just kept getting wider
What do you know about brakes?
Hmm! Good question......They Slow or Stop what ever they are mounted on??
Heavy Boots can be good, They are pretty near to useless on a Land Yacht other than for Parking it.
Why?? Do you think they would have stopped the copper booking you if he had caught you???
Ron
PS, Paul if you are a Tinkerer then Nylocks can be dubious as well unless you throw them away after a couple of reuses. They may be Old Fashioned but Castellated Nuts are a positive solution for safety reasons. You come adrift at a few Kmph it won't hurt much at 100kmph It Is Going To HURT a Bunch.
"Nylocks can be dubious as well unless you throw them away after a couple of reuses."
Now now Ron, thats not true,with some maintance!!!
Just lay them face down on something hard (nylon up) and give them a tap to slightly swell the nylon insert and they are good to go again. This gives them lots more lives, till you cant flatten them anymore.
I know, I know, I'm just a tight arse.
Well I guess that's fair enough too but I will stick to my Constellations. I probably was a Knight in passed lives[}:)] and you know what they say about us Knights?
Once a King always a king but Once a Knight is enough..

Hi Danny
The troops have come up with a plan for the front axle. We are using the Fallshaw wheels...4.80/4.00-8. These are running standard deep grove bearings which allow a 20mm axle. They appear to be 110mm through the hub. If we allow 3mm bearings plus a mill. each side for play this would mean 117mm of bright 20 to be used. We were thinking you could drill through from each side and tap some thread in. A bolt could then be screwed in from each side. Don't know if this is silly or not
Hope you can help
Cheers Nick
tassiefubar,
Is that allowing around 8 to 10mm Clarence in the forks for the tires??. Remember I found the Tractor 3pt Linkage Bushes were excellent Spacers and you also need a Spacer between the Bearings inside the Rim. They are to ensure you do not apply side pressure to the bearings when you lock up the Bolts. On my front wheel I used 4 Bushes I think and had them cut to suit. When the whole thing was bolted down any pressure was applied to the inner Race only.
Ron
Ron from the diagram there is no side pressure to the bearings as the holes through the 40 x 5 flat bar is only the bolt diameter.
Let me know Nick, if the tyre clearance is enough or we need to increase the spacer width up from 3mm each side and make the axle a bit longer.
I'll turn it up this thursday for you out of 20mm 1040 bright shafting (when you confirm the spacer widths)
Really nice drawing by the way. Most of the ones I work from are on the back of an old envelope and the dimentions are only on the blue print. (that is in their bloody head still, ha ha.)
Keep me posted lads.
Oh by the way, don't go to the trouble of redrawing it.
You will loose valuable sailing time.
Just let me know if there is an increase in width of the (now) 3mm spacer washers.
Hi again Danny
Just went and pulled an axle and wheel off.......you can do that when it's not yet welded together!
Ran a ruler along the spacer/washer. Seems to be about 5mm clearance. If I was to put the lugs on the forks on the inside of the forks I think we would have plenty of room.
See what you think from the photos.
Cheers Nick
Yum... just noticed a nice blob of sheep poo on the tyre.......from last night's escapade!
The way we see it there is no side pressure on the bearings......the bolts tighten up on the axle.
Hi Danny
The bearings are 20mm
Seems like more traps for young players
Will run with them until we wear them out.......then we will buy some sealed high speed bearings.
Mounting dual forks for strength seems to me to be essential. If so, using 20mm pipe as an axle may not be feasable as we have to be able to tighten them up from both sides.
My brain hurts
Cheers Nick

Might I suggest that those Implement Retainer Pins you are using be inserted from the Top rather than as shown in the pic's. Otherwise you may come to wish they had been Inserted Elsewhere as the Sprung Loop part will weaken and they will drop out and that will not be fun at Speed.
After having inspected my front Axle, Occum's Razor I have used the same system but instead of using a Bolt I used a Stud, locktight-ed in place and Bicycle style nuts to lock it in place.. The thing is we remove and refit wheels a lot and I felt that it was wise to use the Stud as a sacrificial part if over tightened or stripped so the Stud would be easier to re-create rather than re-threading the Axle to a larger size.. I also used a Large Washer (Checked for Flatness) to cover the entire face of the Bearing. They are very close tolerance and serve as Contamination inhibitors/Covers. Just thought you might think about these points.
Ron
Hi Ron
The retaining pins/axle were upside down because It was the only way to get the ruler and bearing in the photo!
What do you think of the deep grove bearings?.....Falshaw recomended them...humm!
Would we be able to retro-fit sealed bearings at a later stage?...Not rocket science, new to us though.
Troops had a run in the new billycart....had trouble getting them out of it. They think it is great for pulling chicks and does not need masts!
Jess Cole....our PE teacher was one of the first guinea pigs.......she has had a big grin on her face all day
