Hi Nic,
You got your t-molding and slot cutter (with arbour?) from t-molding.com I believe - how were they. It took ages to arrive didn't it, but got there in the end and the slot cutter and t-molding are all good?
Don't know why I'm even looking yet, it'll be ages before I'm installing t-molding, but the research part is easy to do at work, the sawing less so!
