I'm a FNG here, don't post very often but I did run across this thread. I wouldn't have bothered to post except I have to throw some support behind the OP for what he's doing after I saw he was taking some flak. I've been a toolmaker for over 25 years and I also have some "less than efficient" machine tools in the garage I make prototypes with. I know how time consuming cutting these on a manual machine is, I made my last socket like this for my ZRX. I also know how many extra steps you take to make somehting nice to meet expectations for others, done it a few times on other boards.
So if you think that what he's charging (under 30$ IIRC) for this piece is too much you should really try making it yourself to find out how "easy" it really is. Sure there's CNC machinery that will drop this out in a 3 minute cycle time but nobody with a VMC is offering one of these now are they? The price really isn't out of line and if he's done a nice job (some people seem to think so) then cut the poor boy some slack rather than critique him unless you can/will do better for less.
A steering head socket is a great tool to have and seems like he did a nice enough job. I'd order one if I didn't have the means to make one myself.
Not trying to stir the pot, sorry if it seems so. Just wanted to weigh in with my professional opinion on the matter.
We now return you to our regularly scheduled program.
