Yes, I'd be interested to know that too. Wouldn't you have to remove the handle on the old bat first?
Weight and volume if you known the volume then weight and then density can be ascertained.
As Smokey unofficial apprentice and right hand badger the things we have calculated are great and a forward step in bat making.
Handles weight can play a factor too in the weight of the bat but BAT MAPPING is a form like no other
You could say get a picture of your players favorite bat and want a replica made....
In the past we talked about weight then density but cleft volume is more important in a shape.
Smokey has taught me very well and anything can be bat mapped but do not expect a 3lb bat to weight 2-7 as somebody asked recently it is theoretically impossible.
Most CnC reverse engineer things we or should i say Smokey is a pioneer and had brought the technology to anybody who wants it be it individual to small brands.
