I’ve not done marquetry, but I have done things where we have to line up small parts precisely. One way to do it is to use the GF to cut a template to align and hold the small pieces temporarily.
I would cut the template in a slightly thinner piece if you can, so that your pieces are sticking out from the template. That way if you make a mistake, it’s easy to take one out. You then put a bit of glue on the back of each piece, insert it in the template and wait for it to dry. Once it’s all dry, you can remove your template.
You have to be very careful not to use too much glue or it may seep under the template and stick your template to your work.
If they can set up the functionality that lets the GF cut or engrave the back of an object it’s already done the front of (registering one side precisely), GF could also engrave numbers into the backs of the little pieces, so if you were doing a non-regular pattern of objects, you’d know where on the template to put each piece. And, in many cases, I think the template actually could be used for the marquetry’s backing.
Thanks for the references and tips, quite excellent. I suspect that once the GF arrives I’ll be able to try out these different methods and be able to post more detailed questions. Thanks in the meantime.
I’ve been wanting to do something like this but with mirrors, and I’m trying to figure out if the Glowforge can help me score many intricate pieces of glass. (the shapes will obviously have to be carefully selected) I saw some beautiful works like this in the Guggenheim last year: https://www.guggenheim.org/exhibition/monir
What an interesting and lovely piece of art. In thinking about whether something similar could be done in glass on a Glowforge, I wondered how hard a surface the laser could deal with and if its reflectiveness would cause a problem?
For some reason, this segment just popped out at me:
CNC Kerfs Compensation (Cutter Path Offsets)
To achieve a perfect fit, the width of laser cut or kerf needs to be compensated when ImagePaint generates the toolpaths. This width is user configurable via the “Laser” panel. This feature enables the support of different laser models and from different laser manufactures. Note: This setting can be used for any CNCs and any hand and power tools.
I’m still working on the compass rose. Offset and inset in Inkscape are working very well for me. In a 1/4" walnut I add a .07" kerf offset for the fill piece. One thing about it though is that at 1/4" the cut edge is definitely sloped to a center on the bottom so I have to think of the final surface if I’m inlaying thicker wood as the back of the piece I’m cutting.
