I'm a bit new here, and I'm not sure if this is the right forum for this question, but it seems like woodworkers are probably the best people to answer a question like this, so here goes:
I'm using a laser cutter (yes, bear with me) to cut out a pattern out of 1" oak board. Looks like this: This is essentially doing what I would do with a band saw if I could make these cuts with enough accuracy.
The issue is, unfortunately, regardless of the settings on the laser (and believe me, I've experimented), I've been unable to cut all the way through from one side, even with multiple passes. Me being stubborn about wanting to do it this way, I've decided that I want to flip it over and etch from both sides to get the cut. In other words, reverse this pattern and cut that from the other side. My brute-force solution was to surround the pattern with a rectangle so that I could use the four corners to line up the cuts from both images, but with no guarantees that the cut will go all the way through, this feels useless. My blocker is that besides eyeballing it, I don't know how to mark up my piece or build a jig to accomplish this. Anybody have expertise to share?
Thanks in advance!
