Big Wheels

[195E]

Some kite buggies have big smooth/slick wheels, they appear to be half the price of eurocrap depending on size.21/12-8 is £86-00. Problem is they come with stainless bearings 12-20 mm and the sockets they sit in are various sizes around 32-52mm width. The wheel, not tyre, width is 75mm. So, as I am not an engineer, can anyone work out how I can fit these wheels to my fishing boat trolly which I think has standard 1 inch axles. Oh and of course to cat trollys. Here be the bits:- http://www.powerkiteshop.com/accessorie ... igfoot.htm Thank you.

Look into a stainless bar and have it u clamped to the original frame.

I too am interested in the big wheel conversion problem as I am looking to buy a boat but with big wheels a main criteria. That seems to be a struggle. I am an engineer so happy to meet up, hopefully with the engineering nouse to work it out for both of us. Call me - Sean 0780 6613737

Thanks Sean, I am waiting for some info from the kite buggy people, when this arrives I will call you. Thanks...Geoff.

These are the wheels on the Zapcat trolley and they come in standard axle sizes.

Thanks Simon, I'll have a look at those as well then.

Simon, does the Zapcat trolly use the standard 1" nominal aluminium axle or is it a stainless special? thanks...Geoff.

[simongiles]

The original Aluminium axle was too weedy so we upgraded to stainless steel which is still on the verge of deforming.

However Zapcat + Engine + Fuel = Approx 180kg

I think our Darts can't be much more than 140kg

Now I have a boat I have ordered some of the following (22x11.00-8 Scorpion Bigfoot Kite Buggy Tyre & Plastic Wheel - £92 ones) but what is also interesting is that you can fit the tyres (£49 ea.) on the std wheels, although it would be with some difficulty.

Worst case is having to change to a stainless bar so that I can put real 25mm bore bearings on but the plan at the moment is to just get some nylon bushes. I will let you know how it progresses.

They look good. So you have the asymetric plastic wheels?

[mckenna789]

Yes asymetric, phosphor bronze bearings and stainless shafts. All up cost around £250. So far it seems to work well but time will tell.

The stainless was from http://stores.ebay.co.uk/specialised-pi ... 4340.l2563
I got 2 x 650mm (they will cut to custom length for no extra cost.

Bearings from https://simplybearings.co.uk - 1 x AL2532-30 Oilite Flanged Bush 25x32x30mm (AL.2532-30.FL) = £12.57 Pack 5

The trolley is in the park now (next to the gate so happy to show anyone the details - or feel free to have a look.

I have found that a high speed bounce down through the moats that the kids build on the beach as I rush belatedly to the shore has revealed a weakness on the axles I purchased. Reinforcements are on their way at around £24 delivered.
