I glue them up .Just try and get a good tight fit before you glue them. Be very gentle with the sleeves also before they are glued,if you warp them they don't slide together and back apart
easy like they should.I have used tt3 and 2 part epoxy for glue.Just be sure to work fast getting the where you want them if you use epoxy ,when you start to put them on.go on with it and don't slow or stop till it is where you want it to be.
