Number one son was busy making a wheel tidy for my brother's van the other day. He made one for somebody who liked the one in the van. Now he's making another for somebody else.
The wheel tidy welded and cut and ready to be bolted (fitted) into place over the wheel arch. No longer will the owner of the van search for the spare wheel or climb under it to unbolt it.
The spare wheel securely in place in it's new home.
How much would you charge somebody for a product like this? Perhaps this could be the start of a smallholding enterprise. Suppose you could make it out of wood. A lot of industries and businesses started on farms.
