No Madam it’s not a milk bottle

It’s used to strengthen “minilite” hub centres when a securing tab breaks off . The mod works , kept in place with UHU glue

Thanks for that Paul, I like your tips. Mine have a few taps broken off.

It looks like a neat cut out about the size of a tab on the bottle top?

cheers, Dave

Yes make the initial cut as per the pic then force the top section into the hub centre , then trim with scissors in line with the top of the remaining tabs Hold the section in a vice then apply glue liberally to secure
