How To Setup A Parting Tool On A Lathe

1 x 26 x 2mm Parting blade.

How to setup a parting tool on a lathe. When ground flat on the platform not vertical it will. Not a very good shot but it does show the thickness. This tool height procedure needs to be repeated for every tool that will be used in outside turning.

Install the tool tight in the holder and set the holder perpendicular to the part. Never assume the tool is setup properly just because it was in the lathe. Parting off bowls and lids When turning a bowl on the lathe and holding it by a tenon in a multi-jawed chuck the parting tool can be used to part the bowl from the lathe.

Next I took the blade over to the disk sander and ground it down to bare metal. Like all tools used on the lathe the part-off tool height must be checked and adjusted so it is as close to the vertical spindle centerline as possible. There are several options.

I then cut the end of the blade off to square it off and I cut and ground down the teeth. We recommend to use a sub-spindle if available. When machining with long overhangs it is especially important to mount the bar correctly to ensure enough clamping contact.

I shaped the end of the blade like the Sorby Parting Tool double angle look. Parting tools are used for parting through spindle stock and several other operations. Load your cylindrical part in the chuck of a lathe when you tighten the chuck rotate the part with your hand lightly until it cant move anymore to center the turning part.

45 is a good general angle. Often enough to avoid having to face it off in a second op. Second if the tip of the parting tool is ground at an angle it will minimize the nib further.
