Hello Nobade,
Could not help but to give my one and a half cents in here.
Even though someone else has done something it still not necessarily a waste of time. Sometimes it's fun and worth it, just to do it your self. For why do we make our own bullets, casting or swaging? There are bullet companies already doing it. Or why do we reload? There are ammunition manufactures already doing it. Or why do we hunt? The grocery stores are full of meat. Lots of reasons are given to do the things we do but it comes down to one basic reason, because we want to.
So, if anyone out there wants to reinvent the wheel, I say be safe and have funnnnnn at it!
