Spine and edge measurement
« on: May 28, 2012, 08:21:28 PM »
 While making a bat, I always have hard time to make sure the spine is centered and the edges on both sides of the bat are identical. I use elementary techniques to do that.

Can anyone suggests any precision instrument or technique with which this can be accomplished?

Thank you!

You could use some digital callipers perhaps?

I use a ruler for both. Just keep measuring. Usually if your eye says something's wrong, there is. It may sound strange but look at it in the mirror, sometimes that helps highlight where the problem is.

Don't remember this apparatus but I remember we would have one in Chemistry lab, it is cheapest option and perhaps precise too!

Will try to look for its name if not a picture at least!

Ryans compass idea is good as he can check the profile at stages the same way a boat builder would do. I've been using a combi square set to 2 1/8" to find middle. I'm thinking of making a jig similar to a bat gauge with either a pin or some kind of port to house a pencil in the centre so I can just trace down when I need to.

I'm making something very similar right now but the idea is based more on a marking gauge. I go sick of measuring the spine and finding I was way off.

Sounds interesting. I have a design in mind, something which can slide along the width of the bat ( assuming that the bat width is not variable), and the center of the instrument possess  a marker which can draw the line.

Thanks. It's for a good friend who's having a bad run of form so I hope it helps turn his season around.

I've got to get a bat repaired but I should hopefully get the gauge built this week.
