With Great Power comes Great Responsibility

Or in other words, just because you CAN do something, does not necessarily make it a good idea!

So after getting as far as I could (be bothered) in a day setting up to have another go with the Pen Wizard, I wanted to try it, and a new carbide cutter out.

I decided to try acrylic again, which although will work, the inherent patten in which may result in a too-busy-a finish, but “I have the power”

First job is to do all the required steps in making a pen, including getting it up to a respectable finish.  It can be done, but is a lot harder to finish with all the grooves cut.  If I was filing the grooves, that’d be a different matter.

Pen Body

So from the original acrylic (seen on the right), I’ve cut, milled, drilled and mounted the blank on the lathe, then turned it round, then finished it with the acrylic finishing pads.

From there, it is off to the Pen Wizard.

Engraving

The Wizard is set up in this case with the guilloche attachment in place, as well as the depth guide.  A laser bit chosen that is allowed to just be exposed through the guide, then the whole thing height-adjusted to just match the start and end points of the pen, and the stops set. The depth guide takes over once the cutter is at full (set) depth, and then rides up over the pen producing a consistent-depth cut (and in the case of a laser point, a consistent width as well).

With 12 of the possible 24 passes done (using the index wheel between passes), the engraving was completed.  The pen body was returned to the lathe for a final sand, then assembled.

I think the result would be nicer in a plain wood, especially with an infill, but still, the ease of the unit made this a very simple, controllable, repeatable job.

Guilloche Pen

Rather interesting techniques so far – looking forward to trying out other designs.
