Hi George,

A proper CNC engraving tool is not just a pointy bit of metal. The depth of cut is very small. This makes deviation in the height of either the job or your table a real issue. To compensate you require to spring the engraving point so that it can move up & down. This in turn requires that the fit of the engraving tool in its holder is nuts on as any sideways movement will show up on the job.

The amount of compression has to be adjustable and that means a method of adjustment plus you need to start with roughly the right strength of spring which means having a large selection or making your own (which is what I did).

Now we come to tip geometry. The tip should be machine ground to 120 degrees. Not the tighter angles you see on scribes and pointers etc.

So, you could make your own for less than a tenner but you couldn't buy one that'd really do the job for a tenner.
