The wheels are plastic rimmed builders wheel barrow wheels and come in widths from 4 to 8 inches. They can be purchased from hardware or stores that sell engineering supplies. First we need to knock out the bearings and this leaves a hole with almost a 2 inch dia but a slight taper towards the centre.	This taper needs to be removed with a rasp or 40 grit sand�paper so a 2 inch dia axle can be fitted and the wheels move freely on the axle.
These beach wheels are being made for some small 12 ft Surfcats we use for kids training boats at our sailing club. As the boats a re small we are only using 4 inch wide wheels. We turn the hulls upside down and use them as a mould to make the cradles for the beach wheels.	The hulls are protected from the resin with some newspaper and a inch layer of rubberised foam which becomes the padding the hulls sit on when the cradles are made.
Over the rubberised foam we have layed up several layers of 450gram chop strand mat the a layer of 1/8 inch core mat and several more layers of 450 gram CSM. This layup is wet out with polyester resin and the quantity of resin required is 2.5 to 3 times the weight of the material to be wet out.	The beach wheels are nearly finished they just need the cradles to be trimmed and painted and some locating collars of 2 inch plastic pipe pop rivetted to the axle to�keep the wheels� next to the cradles� when the boats are being wheeled around.

Alternatively the cradles can be made from materials other than CSM. Here the beach wheels I made for my Taipan 5 years ago have ply epoxy cradles and still going fine.I have also see cradles made from aluminium. Seems like quite a simple process to shape the Aluminium to the hull make up supports to hold the shape and pop rivet them to the axle.
