Attended Falkirk branch of B&Q this afternoon for advice on suitable board to use for a makeshift table tennis table top. Mark immediately knew the best product, MDF (fibreboard) 4 by 8ft. He then discussed the best thickness and suggested we have the board cut in to two 4ft square pieces, and that we had a choice between the 18mm and 12mm thickness. Mark let me try out the weight of both versions, then even went so far as to place both samples on the floor so I could test bounce height using a table tennis ball. I entered the store knowing nothing about how to create a cheap table tennis table top and left 15 minutes later an expert, who knew exactly the right size and thickness of MDF required. As Falkirk doesn't have a cutting service I will be ordering and picking up from the Cumbernauld branch next week. My thanks to Mark for his professionalism, vast knowledge and patience in taking me through the options, and the pros and cons of each one.
