OK converted.
When I have the time I will post the "how to do" in the tech section. I am flat out at present and expect that I will be that way for a while, so just be patient and I'll get around to it.
It will be a bit hard to explain the machining processes over the web, and only those fimiliar with machining techniques will understand. I will try and keep my explanations simple for all to see.
There is always the option of going to "my photo's" and studying the photo's of the spring loaded locker plates that I have already posted.
