How are the ends of the bands you cut held together?

I buy sheets of SS shim stock. (non magnetic .012" -6"x 24"). I cut the stock from 3/4" to 1/4" width depending on my mags. I drill and tap a hole in the gap, place the band and measure to the hole. I then clamp it together and drill a hole in the band and attach it with a SS screw. I make the band about 1/16" short so the screw doesn't bottom but holds the band very tight. I use a long dry epoxy so it sets overnight. The epoxy holds the mags from shifing and in place the band adds security in case the epoxy ever fails. I lose a few thousands in air gap but it works well and I don't have to overload the armature with epoxy which makes removing the magnets easier if I decide to change the design. (I hate gopping up my expensive mags with epoxy!)
