Rowland, with the risk attached, I can't help but think that using a hacksaw
blade as recommended in the manual, and as I did, is a much safer way. OK,
it takes half an hour to do both TP6's thoroughly with a blade, but I got a
really rough surface and I'll be very surprised if either 'gives' after a
period of time. Drill just once, just that little bit too far, and you've
really b _ _ _ _ _ _ d it.
