Nice job David. There is always more than one way to skin the cat. Odd shape pieces can prove to be a challenge. For laser engraves
a few tricks come into play for something like this. A little playdoe, a small level,
turning the piece & graphic/text to the side or even up side down - use the red dot pointer
for positioning - and your off to the races - set up - a few minutes - engrave time- a few seconds.

Hi,
Along the lines of playdoh........I find more uses for automotive bondo for screen printing jigs than you can shake a stick at. I suspect that if you had multiple parts that it would make a nice jig for a laser as well.
Coat the piece you need set up in a jig with some simple automotive oil, or hold some saran wrap on the piece. Press the oiled or saran wraped piece into a prepared proper thickness of mixed bondo set on a flat board that can be clamped or fixed into place. In around 5-35 mins or so, the bondo will harden. You can then remove the piece and you will have a nice jig for multiple pieces in a laser, mechanical engraver, or many other production processes.

Brian that is a really good idea. Not sure I would have ever thought of using bondo.
The last time I played with bondo it was to patch a 1961 chevy pickup. I was 16 -
and it was my first fixer-upper.
I would suggest that maybe David should put your idea in the tips and tricks
folder.
Thanks

Thanks,
It works very well in lots of situations, is readily available, and is relatively inexpensive. :)
