Re: 70's Ludwig Vistalites
I used to be a cabinet builder, so I know my way around some stuff when it comes to tools and fixing things.
On the crack I used this acrylic welding liquid, nasty smelling stuff! I can't remember the name but in the US you got something like Weld-On that does the trick (Weld-On # 3 if I remember correctly). Worked great.
The crack also happened to be on the underside of the bass drum so luckily it's not really visible.
