OK Bruce, you got me, ordered another set of wheels. Blumbly I was aware of the two asbestos gaskets but if you keep every thing damp so no dust it's no worries, I was a builder for 20 odd years and have had to deal with a lot of the stuff, not a good product by any meens, I now work in a mine and we have a bit of the stuff there as well (natural in ground).
