Re: Automatic boring head?

---
Jig boring is generally regarded as a precision operation and the cut
required is set on a dial and locked after each pass.
The automatic feature of these heads have nothing to do with boring -
just facing, or as another list member pointed out, to make an
undercut or groove.
"Doing the best we can", does that mean that mean that you are
obligated to "take a crack" even if you are not really sure?
Sorry if I upset you but I have found most lists to be a very
unreliable source of information, it is quicker to search out and read
a good manual written by an expert than to sort out the wheat from the
chaff offered on line. I think if a person commits himself to print
and charges for it, the chances of it being useful information is
petty good. But then I come from the old school and do not have that
blind faith in computers that the next generation has.
I got into building my NC machine by visiting the Mendonet site, I
would never have built anything if I had first joined this list, there
are too many members with strong personal preferences that
disriminate against equipment that would work perfectly for many
applications.
Where are the 1300 contributors? there are perhaps 20 guys that take
it very seriously and ping pong back and forth to each other that is
tipical of all groups.
I once posted a technical question on the Nissan owners group and some
of the answers I got back were quite amusing but I learned that there
were no Nissan technicians dishing out free advice in their own time.
Professional advice costs but is probably worth it in the long run.
I guess I do not have the correct attitude or personality for lists?
