This is a Boehringer 19x46 hydraulic tracer lathe.

I have a feeling that the tracer system can be disconnected and it can
be converted to a manual lathe. Is that true?

I have my doubts.

Do you have it home yet? If so -- look at what appears to be a
leadscrew, and see if it is threaded, or just a shaft with a keyway down
its length.

I don't see a quick-change gearbox on it.

It looks as though there is a cross-slide knob and a compound
knob, and a handwheel for the carriage, but I suspect that all require
hydraulic power to make the carriage move. (Well ... perhaps the
compound is manual. :-)

I don't even see anything which looks like gearshifts for the
spindle speed. (Unless those are knobs on what looks to me like a
hydraulic fluid tank.)

You might be able to get rough control by manipulating the
followers for the tracer mechanism -- but I would not bet on being able
to control it with any degree of accuracy that way.

Intersting that it has a 4-jaw chuck on the outboard end of the
spindle. A spider for stabilizing long workpieces? Or simply a storage
place for the chuck, and letting it act as a flywheel? :-)

Thats quite common with long work pieces. About 25% of the lathes I
service are used with long work, such as pipe.




Good Luck,

The methodology of the left has always been:

1. Lie
2. Repeat the lie as many times as possible
3. Have as many people repeat the lie as often as possible
4. Eventually, the uninformed believe the lie
5. The lie will then be made into some form oflaw
6. Then everyone must conform to the lie
