Based on the "MAD-HATTEN PROJECT" designs we created, were still trying to get our head around the Front End of the Land-Yacht.

We were thinking either using a bicycle wheel and front end assembling or to use the Lake Lefroy plans.

If you guys could tell us the difference between them, it will be taken in to account of construction this landyacht

Thanks

Incorporate the two of them if you like; use the bicycle bits in a LLM configuration. But i would use the LLM plans for sure to do it. If you have the wheelbarrow wheels, then follow the LLM plans exactly...

Bmx wheels work fine on the front end of landyachts
PROVIDED they are fitted with the layover pivot setup so they are not
subjected to large sideloads when turning
30degrees seems to be the most common pivot angle for this and has proven very successful
The bicycle wheel bearings work well too --- outlast the rear wheel bearings many times over even though they are not that well sealed I guess thats due to the light loading

Quite surprising what you say about the bicycle wheel bearings lasting so well Hiko.

I would have thought that particularly with beach work they would flog out really quickly.

What about the fork head bearings if using a BMX front end? Will they last well too when used on the beach??

I have a BMX front end I am planning for a future build using the frame tube (ideal size to fit a 50 mm pipe I have) and fork head plus the front fork which will have to be bent or cut and shut to make it "lay over".

I bought a wheel for it that is actually sold as a golf buggy wheel. It appears to be ABS plastic and the hub is set up for conventional ball bearings. From memory the wheel is a 12.5 x 2.25 inch the same as blokart front wheels

I've found the bike wheel bearings surprisingly resilient. We have driven them into the sea and thrashed around in the sand for 4 years. I did "seal" them with silicon though. I thought at the time that this may actually be detrimental......and seal the water in ....I'm a bit affraid to look....they still run as sweet as!

Similar experience with me
I have recently removed the inner seals on my rear wheels and give the bearings a
spray with wd 40 after use and they seem to be lasting better
Too early to be sure on that
We did this on dicing machines in a food factory that used to get washed down with hot water all the time and the bearing life went up dramatically
It seems that trapped water is the killer

Havent used the head bearings yet just use plastic bushes there
I have cut the tube right off on the forks I have done and made an elbow of 20mm shaft with 50mm legs at the right angle, slipped that inside the remains of the fork tube at the bottom and used a piece of heavy wall 2mm or better stainless tube for the new steering tube
I weld the chromoly forks the inner shaft and the ss tube all together with ss arc rods in one go
A large washer at the bottom for the bottom bush to ride on and the whole thing faired up with car bog between washer and forks
No problems so far with with this method
Using the original steering tube would probably be lighter

Went into Hobart today to pick up a couple of Fallshaw wheels for the Madhatten project. As we were stopped at some traffic lights I happened to glance across to a shop that seems to sell nothing but motorized wheelchairs etc. Some of those rigs in the display appeared to have some really neat looking mag type wheels. I wonder if they are rated to go faster than the 15kph that the ones we bought are?
I'll have to hyjack some old codger and steal his wheels for a trial!
It was pissing with rain so I didn't stop for a closer look......next time perhaps

The Fallshaw wheelbarrow wheels are not rated very fast and look what we do to them!
