GM Prepped bats, as I found out to my cost, need plenty of additional knocking in. 30 mins didn't cut it and my GM went back with a fairly significant crack. Maybe up to 2 hours really ought to be enough. The GN's seem much harder and Simmy used his with no knocking in or ill effects.
You have had a few bats that have broken though Liam.. Maybe this is the reason behind it.... Don't know
I'd say it also depends how much time you spend knocking bats, some of us who knock our bats are leaving then underknocked when we think its knocked.One should know optimum level.
I would suggest that 6 hours of knocking in will leave it more than ready...
The way I have been going with my cricket shopping spree last few weeks my wife might knock in my bat with my head
I concur.Also maybe this might sound stupid but mallet makes a difference too! The previous mallet I had was so crap that it wouldn't intend the bat at all! So mallet should be good enough to intend the face so then you can even out the whole face.Is it just me but I have seen some bats getting indentation when knocking/after having first net session while others don't? I believe pressing plays a role here....maybe Tim/Norbs can shed some light on it..
One question I have always wondered is, when we pay extra from a maker to have our bat knocked in for us how much time do they actually spend doing it? I can't really imagine any maker having the facilities or the time to be able to knock in so many bats by hand properly. Is it money well spent or are we better off saving the money and doing it ourselves? I appreciate this will differ from maker to maker but it's still something that interests me....
