That is awsum (echo)... you guys knock these projects out of the ball park. Damn, I always see the negative... if you use the bowl, you can't see that great butterfly and if you wanna see the butterfly, why make a great looking bowl.
Don't know how you segment, however, if you haven't got one, this Mitreset segment is a worthy investment if you do a lot and want quick accurate setup. Just set the two pins,, and adjust your mitre guide on those pins, for the correct 16 segment °.
Not sure how small your little larva butterflies were, and I'm assuming you are lasering, I used inlays in this project, and not my "normal" Timbermate backfill. To give a sense of size,, in the "Muzz" the "M" is 28mm x 23mm and the "u" is 14mm x 13mm, so they are not overly big and "intricate"...
If I'm preaching to the converted I apologise, but there may be someone that will find the following informative.
I cut out the recess for the inlay in the base. I have come to an acceptable laser kerf of .2mm which I use to increase the inlay by that amount ("Contour" command in CorelDraw)... making the inlay .4mm bigger. I then work on the principle that the kerf entry is a tad wider than the exit (no scientific evidence, just a gut feeling), I invert the inlay and cut that way. After righting the inlay I lay it on the base... it is snug on contact. Using a flat piece of wood on top, I genlty hammer it in place with a 20lb sledge... just kidding, tap it in with a small mallet. You just have to remember to keep the little in between pieces of the letters cut out from the base to hammer into the inlay
If your first cut is too short... Take the second cut from the longer end... LBD
