Pick up of a Cricket bat and adding a grip or weights to the handle
Ok you’ve added a grip or some sort of weight to the handle because the cricket bat you have bought picks up like a railway sleeper. The cricket bat feels better with regards to picking up but all of a sudden you’re getting bat vibration from the where the middle was.
The techie bit, only a little bit!
The point at which you get the least vibration from the bat is called the coefficient of percussion [COP]. I think I’ve discussed this before so take a look at another article for the infomation on this.
Hmmmm, by adding weight, e.g. an extra grip, you move the centre of mass or the balance point of the cricket bat towards the handle and this moves the COP [the point of least vibration]. That is because the coefficent of percussion is related to the total mass of the cricket bat, the balance point and the moment of inertia…..
So what does that mean?
The cricket bat picks up better but all of sudden the middle feels like it has shifted by about an inch all because of the extra weight at the handle end!

Hi Andy, I was having a think about extra grips affecting pick-up and the middle position… what about batting gloves? Thinking about it, because of the extra weight of the gloves around your hands, which are gripped around the handle, this would make you feel the bat has a higher centre of gravity?
What do you think?

Hello thanks for registering by the way….
I don’t think the weight of the gloves would affect the cricket bat. The main reason for this is that weight shifted is done on the cricket bat itself and therefore is a phyiscal change to the bat. For example, if you had the bat on a pulley system to help you pickup up the cricket bat the physical attributes of the bat remains the same but the pick up is lighter. The middle of the bat will still be in the same place.
I hope that answers your question!
I should also add the “Sweet spot” is a combination of factors not just the coefficent of percussion. This is the point of least vibration and one of the factors that make a cricket bat perform… I may write a bit on each aspect
