I Didn't Rush it at all! Plus waiting for bits to arrive etc and soaking for long periods trying to soften the gunk so it was spread over a month or two also a lot of time spent building up courage to use more strenuous means to separate the parts! It is surprisingly sturdy as long as you are careful on where and how you grip the parts (lots of lurking on shaving forums for tidbits of info and helpful youtube Vids) Probably a few days if compressed down into a "montage"!
Was a great learning experience Though! Will feel more confident if i ever do another! knowing my luck too confident!!
