Thanks Alfafamily and Swallow. The wifey might have to take my car to work on Monday then!
I had read it could be done without a press, but really I don't see how. If someone could suggest how given the following then I will change my mind, but...
The all metal 'rose bush' joints cannot be cut (laterally) through the middle, as they are fat (deeper) in the middle and thinner on the outside (cigar shaped) you cannot cut through the middle centre , you cannot get a hacksaw deep enough to it.
It works on the other style bushes though. I've used the method after removing the rubber web - incidentally stitch drilling rather than burning out the rubber web works well . Once stitch drilled the centres 'twist' out like carrot tops.
