Great idea Brian and if I wasn't such a long drive from them I would do just that.

I have found that there is a local company who panel out the insides of transit vans and the like with plywood so I am going there tomorrow. You never know they just might be using the right grade and or they might have some off cuts which I could use.

Again I want to thank everyone one the forum for their support in this quest, just think once we find a supplier for me then you will all know of a supplier....
