Bullnose Live Center for UNIMAT 3 Lathes - from LatheCity Purpose of that tool Live center for model work.

The live center with M14-1.0 threads fits to the UNIMAT 3 tailstock. Ideal to work on delicate parts, wood, or plastics since little friction is generated. In particular a bull nose live center is used to work on tubing or all parts that cannot be turned by a standard pin end live center. Size and details The bearings we use have an outer diameter (O.D.) of 5/8” and an inner shaft diameter of 3/8”. A tool steel bull nose shaped pin is pressed in the bearings. The front end is flat and has a diameter of 1/4" the back end diameter of the nose is 3/4", taper angle approx. 60 deg. The bearing is mounted in a steel adapter that has metric M124threads to fit an UNIMAT 3. The entire accessory has a total length of only ~1.8" and is machined from a 3/4" hex bar. The body is 1.3" long + the bull nose end. The live center was tested up to 2800 RPM on an UNIMAT mini lathe. The bearing is self-lubricated and sealed. All dimensions are approximately.

Therefore, don’t overdo it with the loads and RPM. Load ratings of the bearings are given below. Maximum RPM is 2800. However, extensive use at the highest RPM is not recommended. It will be your responsibility to make sure that your lathe is running properly. Alignment problems can cause vibrations which can lead to unstable working conditions. First test Use a #1 center drill and center drill a work piece. Mount the small live center in tailstock and push towards the center drilled work piece. The live center will start to rotate which is best seen at low RPM. Use a marker pin and place a dot on the pin end of the live center. You will need to center drill the work piece or the live center has not enough attachment to the workpiece to turn. If you prefer not to center drill the work pieces, then use a different center such as a revolving adapter. Included: One M14-1.0 bull nose live center, this manual, and a safety booklet.
