They also make a nylon wheel. I don't know anything about these, but they're designed for aircraft, so I suppose they would be tough enough for landyachts.
Here's the link if you're interested:

You can't complain about the price of those wheels, even in US Dollars.


How 'bout this then

The main thing to keep an eye on is that the rim /tyre combination doesnt get too heavy. your wheels look kinda ideal from where we are looking. were your bearings cheap pressed jobs or precision bearings

The bearings were very low quality.
Before ordering all new wheels, I'm going to check with one of the suppliers in my area to see if I can get good bearings to fit my current wheels.

It might pay you to check with the people who sell the Manta or Sirocco yachts to see what wheels they use or even how much or little they can sell theirs for.

Good idea Cisco. I'll shoot them an email and see what they say.

For now, I found some bearings that look pretty good. We'll see how well they hold up.
---------------------------------
On a different note...
I thought it would be interesting to see what my total cost was for my Mini, so here's the list in USD:

Bicycle parts: free
salvaged steel: $20
salvaged Mast/boom: $10
wheels: $45
bearings: $50
Rope/ pulleys: $20
Sail (canvas): $50
Bolts/fasteners $15
welding supplies: $10

Total: $220

So far; Alot of fun for not much money. Just the way I like it.

FWIW, none of the tube sizes which Paul suggests for the LL Mini are available in this country (NZ) but in the past I have built a large number of "torsion yachts" ie no A frame using a very readily available, very cheap material with NO failures.
This is automotive drive shaft tube. A visit to a Pick a Part car yard or similar should still yield plenty, even in the days of front wheel drive.
Obviously it is made to transmit torsional loads, as I guess is drill tube favoured by Paul, but he works in and around mines.
There are many driveshaft sizes, depending on whether it's a Mack truck or an Escort, it is surprisingly light, from memory around 1.6mm wall, no seam, and easy to weld.
We still have drive shaft repairers if you want to buy new tube, so I guess they are in most parts of the world too.

The tube used for the mini in some of the original drawings mention did "Drill tube" but most yachts are using the alternative 60x2 Galv tube as used for fence posts etc which is VERY commonly avaliable.

Unfortunately not available in NZ, and hands up who "Likes to weld galv"!

Gal isn't that bad to weld. If you weld in and open area with a breeze you shouldn't choke to death on the fumes. You can sand / grind off the coating on the area to weld, then use cold gal paint to fix it up.

Interesting to hear that the galtube isnt available. I have suggested drive shafts to some of the US builders ( they do have long cars after all). did use a couple myself in the early days of torsional frames, but when the drill tube got discovered ( By a kiwi geologist in Kambalda) we never went back . I did find the drive shafts a tad thin to work with, and have been informed that a better choice is to buy CDT rom a supplier of steel for hydraulic cylinders . Make sure you order UNHONED tube as it is significantly cheaper . . Perhaps our kiwi friends could investigate a cheap alternative, eg the steel pipe you use to hold up street signs? On the mini chassis's weve found that having super steels just aint necessary.

according to the website of steelandtube.co.nz the have a bigger range of Galtube plus than we do in Kalgoorlie do! some 4 or 5 outlets in a town called Auckland , think I went there once , had nice beer and a harbour, i Think , and one of those big Harbour bridge things

I was given a few years ago a plan titled "Class IV Landyacht"
unknown designer and I only have the page titled information sheet No2


It has the wheel base and track sail area etc of a class 5 and the chassis has 2 rails of 38mm exhaust tube and a back axle of 38 mm steam tube
I wonder what sizes exhaust tube comes in could be a supply source there

Exhaust tubing would get the right sizes, but you need to keep in mind that it is engineered to bend tightly over small lengths The club 88 is built from the stuff and requires lots of bracing,and internal stiffeners.
I suspect that a mini could be built of the stuff , but if you had a big knockdown and it bent ,dont be dissapointed.
Pirrad and Agamackay have managed to build minis from trampoline tube which is probably the same stuff

That is what "Diablo's" main spine is and you know how good it works.

cant agree with you paul as my mini is made exhaust pipe tube ,and it has been bashed over all types of surfaces ,also has no internal stiffening what so ever that is with small wheels and large ones .It has been sailed in heavy and light winds with the only sail i have which is 4.5 sq mtrs, tube size is 46 mm

always happy to discover that Ive been proven wrong . I havent got enough time to do all the possible experiments, so thank you for doing the exhaust tube one . How about putting some photos up in the landyacht register so we can have a look, please
other builders would love to see what is possible

Tailshafts out of motor vehicles would seem to be one of the ultimate materials to build a torsional land yacht frame from. Apparently they are seamless, of higher grade steel and are apparently designed for far greater torsional stress than our application on a land yacht. This could be debatable though when a mast step is welded on. (Research Engineer Gizmo to the fore.)

Given the trend towards front wheel drive vehicles (in the US, many V8 cars are front wheel drive), maybe we should rush out to our local wrecking yards and buy up all the tailshafts they have?? (panic, panic, get 'em before the price goes up, good conservation policy)

For those of us that miss that rush and get stuck with using seamed, low grade steel galvanised ex street sign posts, the question becomes, should the seam of the pipe be arranged in compression or stretch in the construction of the yacht to achieve the lowest probability of failure of the material during the attempts of most land yachters to stretch their yacht beyond it's expected capabilities.

I can hardly think of anybody around here who would do that. We will leave that to the extremists.

Hey niaychi,
Welcome to the forum. First post I see but you obviously are not a newcomer to the sport.

Anything you can add to the knowlege pool is greatly appreciated by all as is your general presence. Cheers Cisco

Hi Paul, the sad thing with Steel and Tube (and others) is that what their catalogues, both online and paper, show as being available, does not reflect what they have.
I simply offered driveshaft tube as an option, cos I have tried it, it works, did not fail and is damned near free at the U Pull it etc, especially if you pick one with knackered unis.

Kemosabi;
have a set of 4 azusa lite 6" wheels I will let go for $60.00 plus freight from longview washington. They are just laying around gathering dust.

Was it this thread that talks about bearings?
Years ago I went to a major bearing supplier and asked if we got everyone to buy their bearings could we get a discount. It ended up that showing a membership card got a 70% discount! Yes seventy per cent.
When we first intro'd the FEd 5 we had coupons to get a number of discounts which we had organised. Is this a possibility to help some of the LL Mini builders?

Thanks for the offer Windcrazy. I'll see how these wheels work out for now.

So far I haven't had any problems with the galtube since I switched to the thicker fencing type. The stuff I've been using is all recalimed, but I discovered over the weekend that I can buy it for a reasonable price new if necessary.

I think I have my sail problems fixed now:
After closer examination of Landyachts' Mini build thread, I realized I didn't have sheet/downhaul set up properly. Big Difference! Time to start cutting and sewing sail number 2.

Mini number 2 is coming along. I got the frame rolling last night. My friend loaned me his Oxy torch setup and I used it to weld nearly everything on this frame. For some reason, I have a much easier time using this torch than my stick welder. One thing though: I learned torch welding gal pipe is more dangerous than using an arc because it releases alot more fumes. Something to keep in mind for anyone else considering torch welding.

I wish!on wheels and bearings the prices are all over the place.
The manufactuers want you to use a local distributer, the distributer want massive markups or dont seem to want your tiny order.
The fallshaw wheels weve been using are made in brisbane . Lots of minis being built in QLD so it should be easy for them , but the prices are all over the place.
In WA , I gave up using the local agents , and the state distributer and only buy from the manufacturer, copping the freight myself, so I can get the stuff in a reasonable time frame. fortunately the support network were building up seems to be getting better, dont forget we're often dealing with places and often countries where weve never even been!
Could you try getting that galtube from Chile, theve got it.
When i googled for the galtube in Auckland, many of the hits were from fencing suppliers.
They all seem to use the 50mm stock .the 60mm stock is usually used at gate post and corner posts so that could be another avenue.
most certainly , if you can find sources of near free suitable tube , thats the path I would take as well. Ive never been a big fan of paying too much.In fact Ive kind of made it a religion to build for almost nothing another source would be the cross tubes on car chassis's as well

They MIGHT be made in Brisbane but when I order them through our local retailer they come from Melbourne which the retailer assures me is Fallshaws only premises these days. Not that it matters much.

Local price here is $44 which seems to be as good as it gets anywhere.
