^ From what I have heard, James Laver has a rig he uses to determine which clefts are worthy of being called "Signature".

Probably curing diseases, not listening to our nonesense

i cant remember exactly who did it (its on youtube somewhere). a bloke attached 3 bats to an air pressure powered lever arm, one was a gray nics, one a laver and wood and another older style bat. they used the bat swing speed and the same ball as constants and then measured the speed of the ball leaving the bat using a super slow motion camera. i cant remember the exact results but the 2 newer bats performed far better, as was to be expect

Yes, I remember that video, it was done for some TV show.

I'd be interesting if someone could create a cheap rig that could be used by bat buyers before they paid for their bats.

Gents, we are giving up too easily. Where are our scientists?

If you wanted to, you'd basically clamp a bat up and fire balls at it, then see how fast they came off. Baseball has a standard testing procedure in the US: http://www.ncaa.org/sites/default/files/2016PRBB_BBCOR_Protocol_20160901.pdf

Measuring ping is reeeeeally easy, we all do it with mallet tests. Quantifying that accurately is harder, but still not all that complicated.

I wonder if we'll ever see a maximum COR (ping) regulation introduced into cricket accompanied by deregulation on materials etc. Lots of potential benefits, limited supply of willow would cease to be a problem if composites were allowed to be used for example.

Heavier, slower L&W rebounded the ball faster.

If you have a search around the forum, we have done this before.... http://custombats.co.uk/cbforum/index.php?topic=16826.0 Sadly the photos are on Photobucket...

I think a test with tongs can be done in physics lab to measure the frequency. I remember doing similar experiments in school lab where we would hit a tong with a rubber block & we would measure the frequency i.e. vibrations of tong. We can replace the rubber block with the bat (middle). I always feel the ping is related to frequency (that's my theory) as it is related to vibrations (in terms of bounce) & in the end related to sound due to that.

We need to borrow some kit from a good golf club fitter, something like a Trackman, accurate measures of swing speed, ball speed, spin etc. Coupled with a Bola and some kind of automated swing could be interesting.

What if the bat is a rocket but is slightly delaminates? Would Your frequency theory work with that?

Testing ping by looking at frequency wouldn't work I'm afraid. You could look at that kind of thing to find the middle of a bat in theory, but wouldn't tell you anything whatsoever about how far the ball will go off it.

There is inherent dishonesty in how bats are marketed and sold.

I think bats should be re-graded for different conditions and not just "aesthetic" (grain based) grading.

Clubbies who play in slow outfields may requires bats that are easier to play aerial shots with. Fast outfields may not require a lot of ping (case in point not so pingy "pro" bats). Bats for fast/bouncy pitches should be graded as such than slow/low pitch bats. Bat grading should be a combination of the different dimensions which would obviate the need for "ping" measurement being relevant.

As things stand now, knowing "ping" number of a bat would save buyers a lot of headache, heartache, and pocket-ache.

Ping number would just become a sales gimmick to justify selling bats at a premium. I'm shocked a marketing department hasn't crawled over the idea!
