What exactly do manufacturers like GM do to bats to knock them in. Like for how long do they do it? do they use machines? What do these machines do?

[Howzat]

May be wrong but mostly I think its just an extra hard press through a machine!

[Arthur]

Some manufacturers have a machine that knocks the bat in, using a mallet, and they vary the speed and pressure at which it hits the blade.

Some hand knock in too with a hammer, my first Fusion was done like that and I remember hearing another company did it too.

Newbery knock theirs by hand with a cobblers mallet, Chase use a machine with a heavy metal ball on an arm, Kookaburra use a machined bar in a press to give the impression that it has been knocked.

my first workshop prepared bat was my recently accuired Salix Pod 1. By the look of it, the bats seems to have been lightly oiled and pressed and then sanded again to get the whiteness in the willow back. I have tapped/knocked it with a mallet and only very minor dents appeared.

I had a look at the Kookaburra Ricky Ponting Kuhana (Kooks top end bat). It has a wave sort of a feel on the face as the bat comes factory knocked-in and ready to play.

I have not tried the Newbery bats with hammer Edge treatment, but hear they are knocked-in very well.

However, I feel it is more fulfilling and satisfying to put in time and effort to knock the bat yourself....

How long would u guys recommend knocking in for? And using what technique? I know the edges and toe are obviously the most vulnerable areas...
My philosophy on the pre knocked-in bats are just knock them in normally anyway, the more knocking in the better

Mark Waugh used to just take bats into nets and hit the ball as hard as he could for an hour or two, if they lasted he deemed them a good bat

[yvk3103]

up to 2 hrs is more than enough for the softer pressed bats. the first blow should be the hardest then work around the dent created to level the face.

i think if you can over knock in though, why keep bashing the middle with a mallet, surely u want it as receptive as possible. When i got my fusion james cornforn told me just to play it in nets rather than knock in

[Talisman]

Knock as hard as you like until you get any more than small dents, only work the edges and toe. Old balls in nets are great at knocking the bat in and you get the fun of batting rather than the pain of knocking.

Are bowling machine balls ok for knocking in as well?  They are pretty soft so I can't see them doing much harm.

[jandgcricket]

Richie, use an old ball fella.

[Richie]

Yeah, sorry.  I've just read what i've wrote; what I meant to say was could you knock it in on a bowling machine?

[Matchett]

Knocking in is very over-rated.
