Does my bat need much knocking in?
« on: June 10, 2014, 09:29:04 PM »

Hi all,

Manages to pick up a lovely ton legacy last week. The shop had half a dozen and I tried them all out picking the one that picked up the best and also had a very nice response off the mallet.

Problem is, I think it's fairly hard pressed as although I've knocked the squarish edges in any amount of knocking the toe in or the middle of the blade is having no effect. I've had quite a few throw downs and even a newish ball isn't leaving any marks/indentations.

Am I ok to start using this, as it seems little point in knocking in the face when I can't see any progress whatsoever.

Anyone have any advice?

In my opinion as long as the edges are done and you're not getting the seam marks then you're good to go.

I have a few mates who refuse to do any knocking in, saying they'd rather play with it whilst it's soft. I am fairly sure they aren't right but each to their own I guess.

I had the same issue couple weeks ago after I got the bat knocked in from the place I bought the bat , but still felt really hard and vibrating after couple of 10 min net sessions. Then I uses the bat in a match regardless of it's hardness and used it for 25 overs , later on another one hour against the bowling machine which made it to start responding really well.

Providing You  have spent around 6 hours knocking your new bat in and there are no ball seam marks on the blade then it should be okay. Bat  fibres take time to open up my match bat is in its second season and has just started to do so.

6 hours????

Pah. I never mock a bat in for that long unless it is really soft.

Edges, toe and ready to go.

I might knock the middle in if it is gonna be used against a new ball.

Ha Ha if you knock your bat in for around 6 hours it could extend its lifespan and also delay it  cracking it could also assist with timing the as with any bat the ball should bounce off the blade rather than sound as if it as been hit it with a plank.

Where does this magical 6 hours come from. Surely it depends on how soft the pressing is in the first place. This appears to be fairly hard (a la GM) and therefore should need less?

I'm pretty sure knocking in has nothing to do with timing at all.

Also, it makes a fabulous noise with the ball already  :D

I think the time taken will depend on the extent of factory preparation.

I always give the edges and toe about an hour and a half in total with the mallet (maybe more if she is a stunning looking bat) and then go and hit about 2-3 hours of bola balls then she is ready to rock the nets.

Time is all relative to the bat's needs and the tools you use. The fingernail test is always a good place to start when trying to figure out if it's ready. There is a uni paper I found on the net that tested the effect of knocking in a cricket bat and they say four hours is enough time to double the surface hardness of a bat and is when the fibres have compressed sufficiently and any more just  compresses the fibre deeper. That said I think you need take this figure with a grain of salt  and take great care knocking in the toe and edges if you want the bat to be more durable and last a few seasons. Another paper I read studied the reduction in performance by knocking in and came up with a average 3% decrease in rebound for 6-7 bats tested. I think the highest was 7% and the lowest less than 1%, so sometimes the willow itself makes a big difference in how much you may loose. I'd rather have a bat with 97% of its power for three seasons than one with 100% for 6 games and then it cracks.

If what you are saying is correct, it seems like your bat is knocked in. If you have a new ball, bang it as hard as you can on the bat, and if there are no seam marks, it is ready to be played in.

Well, the importance of knocking shouldn't be underestimated. It is not done just to compress the fibers - that is just one aspect of knocking. The other one is breaking the handle. A new bat has a very stiff handle and the knocking process loosens the twine enough to give a vibration-free performance. That's why the feel of a knocked bat is softer than a new bat. People say knocking reduces vibration and the reason is your handle becomes slightly more forgiving for a mistimed shot.

Also, with compressed fibers, the seam can't cut through the blade. To reduce the knocking time, I generally work on the edges and toe and them apply 2/3 scuff sheets and take it into the nets. As the bat gets older, I start removing the sheets. By the time the second sheet comes off, it is ready to go into a match against a new ball. Getting the edges and toe compressed is very important.

If you further want to reduce your work, you can lay your bat on a very thick towel and then strike it with mallet. When you generally hit it with a mallet, the bat swings back and it causes loss of power during knocking needing more impacts to achieve same amount of compressing. If you eliminate the back swing, your knocking time gets reduced. The downfall to this method is if you knock it too hard and too much, you may lose some of the spring, so be a little careful and don't overdo it.

A right heavy one. The lignum vitae they have is decent.

6 hours, 4 hours, I guess it depends how many hits per minute you do.

Definitely a lignum vitae.  I can put you in touch with the maker of ours, if you like? They are made to order.  Ours is smaller than most, as I wanted it the same shape and size to the Gray-Nicolls Deluxe.  This brought the price down to £63.  Usually they cost a bit more, though.  Still worth every penny...
