did he just turn the 510 down to the same size as the other insert?
does it come apart or is it permanantly in there...by the looks of the set screw it looks removable.
No, Tom made a new shell threaded for the VT 510.
Like I wanted too do with the existing shell. But I couldn't do the work nor easily get the exiting shells to him.
New shell installs like the old one, then the VT threads in too that.
edit: here where I first mentioned drilling and tapping the shell, back in June.
Soon after I bought a FDV connector and a drill/tap combo to try it.
All of the BF 510 assemblies I've seen are threaded M10 (1.0 or 0.5). The hole for Paul's shell is bigger than that.
I think the shell could be drilled and tapped. Have to work out electrical connection.
