The "interfering with each other" is the problem. I have a
Dickson style which is smaller -- for an Emco-Maier Compact-5/CNC lathe,
and it has only two stations, but I can still only use one at a time.
One station is for turning, the other for boring and facing, so the
tools point in directions to cross and interfere with each other.

I guess that with a three-station toolpost, you could mount two
tools on the opposite stations, leaving the boring/facing station empty.
I'm not sure how useful that would be, however.


I do a job occasionally in which I save some machining steps by having 2
toolholders in the Dickson, one slung so one tool passes slightly under
the other. The part has a recess in one end and a shoulder the other, I
use a trepanning tool to form the recess and shoulder, in separate ops,
and so bring the tool in along the lathe axis. I have a chamfering tool
slung under the trepanning tool so it cuts a chamfer on the OD on the
face with the recess and at the edge of the shoulder. Takes little time
to set-up and saves quite a bit of time compared to swapping out the
toolholders for the trepanning and chamfering ops.

O.K. That sounds like an intersting way to use them, and for
the chamfering, the below center would only somewhat change the angle of
the chamfer.

I thought you last post of 5:39 on the machine screw thread excellent
and summed up everything very well with regards the general feeling with
the facts or lack of them given by the OP. I probably shan't make any
further contribution there as the OP seems to be unwilling to clarify
the breakage situation.

Agreed. I'm getting close to killfiling him, because I remember
him coming in with some other question some time ago, and being
similarly confrontational.

Not sure about the 5:39 post time. I was posting between about
8:00 PM and perhaps 1:00 AM -- but it may be that your newsreader is
translating the date/time information for your specific locale. Since
you are in the UK, there would be about a five hour difference. Right
now, it is 10:46 PM local time, and 3:46 AM GMT, so a posting somewhat
after midnight here would have been posted somewhat after 5:00 AM there.
I'm too deep into the reply to check your newsreader in the headers.

Enjoy,
DoN.
