Screw down the pieces. First only three sides.
My son is helping to hold the floor so hubby can file it to fit.
Check the wood and plastic fit properly by putting them in place and then trying the last piece of metal. You may find you need to sand the wood to get the fit right. It is a case of millimetre work here. You cant possibly cut it exactly. A good file and you'll be able to get it to fit perfectly.
Just like that.
Use tape to hold the corners if you dont have enough hands.
