We've built some sliding seat mounts.
Nice how the Duragal comes in such handy sizes.....telescopes quite well.
Pity I don't know how to do all this in Alloy.
The front seat will have about 400mm of travel, the rear one only 250mm.
The rear seat's mount will have to go over both the front and the rear of the back cross member. We had to cut 250mm off the bottom face of the Duragal, and left 80mm each side , hope its strong enough
O'Sully was pissing himself laughing when he tried it out
Now for the mast positions......the fore mast is easy. The main's position will be determined by how close the fore mast's boom is able to swing through while keeping in mind that the greater the gap/ slot between the two the more efficient it will be.
We don't want to make the whole thing too long though.

Wow !!!!! How good is that.

It's just fantastic to see companys getting in behind school design projects.

This is our future engineers coming along here.

Well done guys.

YEAH!!!
Progress at last!
Having a bung back for the last month has really slowed things down......back on track now
We figured out the positions of the masts and seats and got into it.
Issac has had some lessons in welding.
The fully loaded trebuchet/ ball tearing thingie to pull the roll bar into position was a hoot.........all balls survived....even though it was touch and go there for a while.,
Have to work out the width for the rear wheels......and find something stronger than broom sticks for axles!!
What is that stuff you guys use for axles?
Issac, having spent a few hours drilling holes has vowed to work harder at school and not get stuck in an assembly line!
Bugger!!! Just ran out of MIG wire

This has been a fantastic deal...especially when you consider that the guys we got them off come from the NW of the state and we are miles away down South.
Yep...Tassie's a BIG place!
I also have to put in a huge thank you for the support and materials that have been provided by Steve Walker Sails. What an excellent effort from a couple of small, local and enthusiastic players. THANK YOU SO MUCH!
On a sour note, however
Have mulled over whether to say this or not for the last week........but .....booger, what the heck.....so here goes.
Took a car load of troops into Hobart to get some gear organised for our HPV.....so decided to see if we could garner up some support for the "Mad. Project" as well. The company we approached,(A large....Australia wide player!) perhaps due to an ominous degree of prescience...hummm......categorically said "BOOGER OFF! it is company policy to refuse all sponsorship...blah...blah etc..."
I fully understand that business players, no matter how large have no obligation to provide any support for anybody. The thing that rankles with me is that this is a mega company that seems to undercut all local competition...and floods the market with cheap. imported products.
The following day I recieved in the mail a cattle dog from said company.....however, there is no way that I will ever be buying anything from them again. It seemed a distinct lack of business acumen.
I'm buying local...no matter how much it costs.

Hi Ron
Is one allowed to name these guys on the forum?
Boy...they do make me cranky but.
AND.....I know 5 young extremely enthusiastic sailors who will definitely think twice before they grace the shop's entrance.
BAD FOR BUSINESS! PERIOD:(

Quess so!!!
I think they were a Witless bunch that sells Worthless products...enough said

Paul,
Are you suggesting an Aussie Company did that?? What Planet are they from.. I have found very few Aussie Companies that even bothered to reply to emails.. Whereas Americans are looking to do business and be as helpful as possible.. I had become of the opinion that Aussies Couldn't give a S^&%$&* and that, "This is what we sell Take it or leave it". The helpful ones, with the exception of Edwards wheels bought their products in from over seas anyway. Shoot I can do that for myself..
Why involve a middle man??
Ron

Hi Tassiefubar
That is funny.. There will always be someone to put the Lie to any statement.
It is good that Fallshaw are encouraging input into their products.. More Power too them. I suggested to Edwards that they look more closely at our chosen sport with a view too creating a line of wheel products more suited to our use. I then found BrisKites and their wheels (French Imports) which are hard to get hold off. Perhaps Fallshaw would be willing to look into the matter as Edwards don't seem to be interested. As it turns out Kite Buggies use the same as us and Larger so that creates a larger Client Base/ Niche for a Manufacturer. There are coatings and materials that aren't as inclined to Corrode in Salt conditions and there are quite a few people about that are prepared to pay a little more for a higher Quality of product..
Ron

Today was a windy day in Tasmania, so we took the chance to do a bit of land-sailing on our wet, grassy oval.

It was a perfect chance to train some of our new recruits wanting to be in involved with our MAD-HATTEN group at C.D.H.S.

We didn't go very fast but that didn't stop the learners from having fun.

Here are a few pictures that I took of us having a good time

Izac,
I hope you young blokes really appreciate your Instructor, Tassiefubar. You don't know how lucky you are. Sure I am getting old now but in my day if you didn't play football or Cricket you were a wright off. They just weren't interested in the Odd Balls.
Go for it Be young and enjoy yourselves but please be astute in your Learnings. Much of it may not have an effect on the Life you choose but you will never know until you have lived it. Live long, Play hard and Love carefully.
Ron

The "MAD-HATTEN" group is very lucky to have a teacher like Tassiefubar who spends his free weekends on building the "MAD-HATTEN PROJECT"

I could not think of any other teacher who would have the experience, and let alone teach us their skills to us!!

And I believe land-sailing will have an effect on me down the track because I really enjoy working on the landyachts, Leisure time + wind = land-sailing for me

CAUTION!!!! LANDSAILING IS AN ADDICTIVE SPORT

I am a bit worried about your front wheel and fork setup. I would rather see a Fallshaw wheel on there and I think the front fork material size looks a bit light for the two-up two-masted concept. Could you post a close-up photo of that front end please.
What you are building has the potential to get up to some serious speeds, and there will be a lot of load on that front end.

Yeah! Tassiefubar,
I totally agree with Clemco. This problem has been confronted in earlier threads by Landyacht. Hence when I did my build using BMX Front End I fitted a Solid Rod down most of the Steering Tube as Paul suggested that repeated heavy shocks would bend it. For the Razor I got too work and formed the Forks from 3.5mm wall thickness 25mm tubing then welded the Axle Mounts in place. The Forks were designed to suit a 480/400x4" Wheel, it has about 5mm clearance either side of the tire. You definitely do not want a Front End Collapse at speed. Someone will get hurt and Parents do get a Tad Miffed when their little darlings are injured, so better sure than sorry. People turn faster than Boomschlangs and will bight the hand that feeds them as well.

The outer Steering Tube look like a nice long one, you should leave enough of the inner tube of reinforcing for the Tapered Wedge of the Handle Bar Tube and about 10 to 15mm above to lock the tube in place to take the Steering Bar (Handle Bar). The Razor and the Cat both function fine.
Ron

Tassiefubar,
I guess I was lucky as I know someone up here that has a small lathe and we cut a 25mm rod to suit the bearings and bored it through the guts to take a threaded rod which then was locked into the forks. Simple and effective I also had to use spacers in the system to lock the inner Race down. These were made from Tractor 3 point linkage bushes, a couple of bucks from your local farm/tractor sales point.
Ron

Lunch room type plastic seats for years have been used as land yacht seats... you possibly have a few with bent legs around the school (like you have used in the tandem version you are building)

I was wondering if your students could do me a favour?... can they measure the rolling resistance of your 2 yachts, I want to get actual figures of 2 similar yachts but with different angled back wheels.
It would need to be done on a hard flat surface, with the same passenger, same tyre pressure, don't worry about the rig. Use a spring fishing scale to see how much force is used to get it rolling to walking speed.
Lets call it a maths / physics project

Several here, but I have no idea what it would cost to get them there.

I have 2 made out of plastic that you can have for free, but I need to research the shipping also. PM me if you are interested, and can wait a little to get mine.... cheers



I'll donate the seats and the shipping for a good cause like this one....
