30 watt Laser in action.

Not mine, unfortunately.  This one is Stuart Tankard’s.  It is a Ytterbium generated, 30w, fibre laser, and the wavelength is such that the 0.01mm diameter beam will burn holes in metal.  Ytterbium, for those who can’t be bothered to look it up,  is a rare earth metal, atomic number 70,  Stuart has used the laser to cut parts from a 1.2mm thick hacksaw blade.  And in the following video he is making marks in a work-tool rest which I will use on my Radius Master sander grinder.

It is a 360º protractor, and grid lines at 10mm intervals.   Looks purposeful.  Time will tell if it is useful.

Watch the video.  I am experiencing tool envy.

 

Listening to my own voice is pretty painful.  I hope that it doesn’t grate too much on you.
