Title: Delamination
Post by: pacman75cricket on February 22, 2011, 11:08:47 PM
I have an ex pro's bat which has been repaired & seems ok but face has some de-lamination so sounds a bit different to other bats was wandering how de-lamination effects performance.

From what I have experienced, it does not affect performance at all, if anything, it improves it, but it only gets worse I find. Delamination is simply an internal crack under the face of the bat, causing a hollow sounding spot.

Sadly it is a killer, glue it back down and you get no performance.

Grains and small sections lifting on the face are a sign of a great playing bat, sadly the end result in time is a lifting and separation of the whole face.

I repaired a bat for a guy at our club which was de-lamination in different places, and it goes fine. Performance not really effected in this case...

I should also add that I held the face down using a bag of pea gravel! I thought it was a good technique!

are you sure it was delaminated?

there are no surface cracks on my bat, the face looks fine, but if you press it in a certain area, the face goes in. when you strike a ball on it flies but sounds strange.

how did u get below the surface, what glue did u use. i have heard if you glue down the "spring back" aka ping, is reduced.

I made a small hole in the face and "injected"* some Polyurethane glue, drill the hole at the top of where you think it starts to delaminate, then let it slide down, the polyurethane expands a bit in to the gaps as it dries which helps too.

According to the guy whose bat it was it went as well as it did before, maybe just got lucky?!

*I decanted the glue in to a smaller tube, and short of forced it in.

So effectively laminating the de-laminated area ;)

I'm surprised an umpire would allow a player use a bat in that state against a new/newish cricket ball.  Surely it would inflict some scuff/scratch damage to the cricket ball and alter the state of the ball. (maybe even allowing it to reverse swing early on in an innings)

unfortunately Lekka, Indians have the umpires running a little scared at the moment, the massive whinge it produced wouldn't be worth the headache.

There's an anti-scuff over the top of Sachin's bat, so it wouldn't be as abrasive as you might think

Have a look at the pic again Johnny. To me it looks like it is just showing the "Hammer Edge" logo strip cut just below the "Edge" printing.

Fair play - I think you might be right about that.

Is that an attempt at subliminal bat advertising?

in the absence of an Newbery edge branding he's done this instead?

sorry to bring up an old topic but I think we had a delaminating bat last night. The inside edge to the first grain started lifting from the toe two/three inches down the bat. The lifting is exactly down the grain and at it's worst at the toe. It's a 2-3mm thick strip. Should've taken some pics I know!

Anyway I've taken it home and glued/clamped it. Problem with it being the edge is it's tricky to clamp across the whole area, so I used rubber bands to maintain pressure along the edge area while clamping the face/toe area.

Pictures would help, but I don't think what you have is delamination. Might just be grains lifting, and what you've done is exactly right. Rubber bands work better than clamps. Better yet, try cutting thick strips from an old bat grip (3/4 - 1 inch wide) to get more uniform pressure over longer cracks.

Delamination usually happens in the middle of the bat face, usually at the sweet spot or higher up. The tricky part is there are no cracks in the face through which you could apply glue. You have to create an artificial opening or just let it be. I make a very thin slit along the grain using a knife and force in the glue through it. PIA to fix, that's for sure ...
