My table tennis rubber is to big for my blade what should I do?
I recently purchased two sheets of brand new rubber from table tennis direct .com the sponge thickness is 2.00mm and I didn’t know at the time of ordering that the new rubber sheets were gonna be to big for my bat what should I do I need anyones help immediately
Either trace around the bat so as to put the shape onto the rubber then cut it a little smaller or stick the whole thing on and then go round with a sharp knife like you would when doing the pastry on a tart and cut of the surplus
Is regularly cleaning your table tennis rubber worth bothering with?
