You may be right on that though he seemed to be on track with testing and all. Probably got busy with other happens to me all the time. The one thing with CA glues from my model airplane experience and trust me I built many is that it is hard a glass and can be more than a bear to blend (unless today’s formula is different). So I’ve purchased Starbond and used it on my TVM paying close attention to wiping any excess. I would avoid any fast setting CA like crazy glue sets immediately. I am not a fan of accelerators and try to avoid using them. The Starbond which I do recommend is a slow cure thick and medium CA. Slow does mean overnight you should test on scrap material. So when using in a barrel channel by all means resinstall the barrel with some wax paper between the barrel and repair. I have not used the accelerator I purchased though I do remember from model airplane days the accelerator caused heavy application (gap filling) to swell and expand. Not sure if that is still the case. CA is great stuff for patching your self after a slice with a knife; I understand it is used in surgeries for some time now. No I have never used it for such but it is used. Excess tite bond is pretty tough too but nowhere as hard as CA glue. I think there’s more flexibility in traditional glue so if it came down to one or the other I would stick with titebondI have a funny insight that if the truth be known ... he went to fit the barrel back in and it didn't come close to fitting. Rather than face the landside of criticism for not putting the barrel in when fixing the crack, like everyone suggested, he decided to dive out to save face. WZ
