Low Density Bats
« on: August 21, 2020, 02:47:21 PM »

If two bats have the same weight, one is a low density cleft (hence bigger in dimensions) and the other a normal density bat, is there a difference in the performance of the bats?

Who dropped their can of worms? :D

All things being equal the bigger profile is stiffer by virtue of cross section size and the micro structure is likely to be very different in those two clefts so the low density should in theory perform better, or maybe just be easier to get an optimal press. You will also feel chuffed to nuts with a bigger bat which is worth 10 runs*

That is not to say the difference is substantial or the smaller bat will never perform like a bigger one as there are a lot of other factors at play. But I guess the lower density gives you a better chance of a stonker of a bat and they look cool. You would also expect it to not last quite as long assuming the water content is the same percentage.

If you want to massively over think it and if the bigger bat is significantly larger, then the physics also says it will feel different in how it rotates around the long axis of the bat.

I think the main difference is in the price.
There is no set in stone rule here except for one, in my opinion.

Only that bat is good which feels great in your hands. If the pick, feel and balance corresponds to your muscles and ligaments to send an accurate and timely massage to your brain, the bat is gold.

Is that not mass rather than volume?  If lower density gives you bigger volume for same mass then surely there is no difference here?  Unless the actual micro-structure / rebound qualities affect it as well?

I think what Dan is getting at is that if the bigger bat is significantly larger in volume, the difference in how the mass is distributed could affect how the bat feels.

This hardly matters these days. Due to growing conditions (warmer summers and wetter winters) there are less and less lower density clefts which come through.

The key point being missed in this conversation is the moisture in the cleft. A cleft which is over dried to reduce weight (NOT DENSITY) will feel lighter when made into a bat however will be more brittle than had it not been over dried. The same goes to a low density cleft, because this is less fibrous the structural quality of the willow suffers and therefore the longevity.

Forget size of bat, think of pressing  to give ultimate performance !

:D

Good to add that a *light* cleft by over drying rather than density at x% moisture content is a recipe for a good time not a long time :D

But why do overdried clefts feels so nice?

That is wandering dangerously in to the territory of Keeley advocates :D I'm joking but it is amusing how buying trends are changing

Trends are having to change I'm afraid

I was trying to read about the same on the internet and came across this interesting article from Cricinfo.

Chris King (bat maker for Cook) talks about the Psychology of bat making

It is an interesting article but Chris King is usually about 3/4 right about the stuff he says- a bit like the video where he said modern bats don’t need knocking in that got pulled the same day by GN. There are laws physics (?) which say bigger is *better* (stiffer) assuming other properties remain constant and he also neglects the different internal structures of different densities of willow which change the mechanical properties. He is right about size up until the point where bats of the same weight distribution and mass have the same rotational properties.
