Peter, what is the actual thickness of your board? For me, making perfect cuts will be harder if it is much over 2mm. Could you share more info about the specification, museum or conservation and any PAT test certificates? I like the larger size, very much—hope the price is good.
The board I stock is 3mm thick. I could get the thinner board if you wish but will have to check prices and minimum order quantities and get back to you.
