It would be really nice to have all of OL`s thread into 1 thread as an overview.
Im not saying to put all the info in it,
but more towards a list with links like this:
1. How to make rings into the mag-body by using files (link)
2. How to make grooves into the tailcap (link)
3. How to make your own battery carriages. (link)
Because after a while, it gets a bit difficult to actually find the info you were looking for.
Just an idea for someone with loads of time!
I know this wouldn't let you adjust the focus but couldn't you just glue the head onto it? As long as you glued it in the right position that would work well.
Sounds to me like you’re looking at getting a lathe. There are people like me who would be willing to do simple machining work for a song. Boring the head and cutting 20TPI threads? It’s an hour of work. Pretty simple stuff.
I think it’s looking pretty good! I’ve been trying to think up a way that you could jury rig a drill to hold the threaded piece - perhaps a threaded bolt and an expanding piece of rubber to grip the inside of the piece. Then you could fix your drill to your workbench, make sure the piece is square and use a file to smooth it down to roundness.
It wouldn’t work for large pieces, but should work in theory for taking off small amounts of material from something like this. Just an idea
