Pyramid Point Tool

This tool is shown ground with 3 cutting edges, each very much like the vortex tool.

I found one recommendation of gluing a nut to the tool at the ferrule (or making the ferrule a nut). Three of the nut's sides provide a great reference for ensuring the edge is presented to the grindstone consistently.

General Guidelines

Tormek Jig
15° - 20°

Some turners will increase β to be as high as 45°. That will work for some activities, but does not provide access into tight areas necessary for turning beads (especially smaller ones). I find the recommended angle (β) to be better for such work. And if you are new to this tool, learning to use it at that angle will provide for more options as you improve.

The Projection Calculator on this site can be used to calculate settings for different values of β. This calculator is web-based and does not require Excel.


Notes & Comments

Information regarding Grindstones

This tool is one where reshaping the cutting surface can be onerous, and the Tormek BGM-100 Bench Grinding Mounting Set can be quite useful. When grinding on a high speed grinder, all the settings remain the same.

Before the first shaping of this tool, look at how you can make the re-sharpening repeatable with minimal effort.

I found one recommendation for gluing a nut to the tool at the ferrule. (If you are making your own tool, consider using a nut for the ferrule.) There is a picture of this to the right. Three of the nut's sides provide a great reference for ensuring the edge is presented to the grindstone consistently.

I used 2-part epoxy to attach a 1/2" nut to mine as the tool had a shaft of that size.

I had to drill the nut's threaded area out a bit to enable it to fit over the tool's shaft. The minor diameter for some options are:

Sean Rubino's video below shows how to make a point tool, and it is quite good. The jig that Sean made is worth considering for sharpening this tool. If you do make one of these jigs, consider making it from metal (e.g., aluminum). And add a brass tipped set screw to help keep the tool from rotating in the jig when sharpening the other three faces.
