An update, I have added the flags of The Danish Realm, Kingdom Denmark with Denmark, Greenland and the Faroe Islands. The flag of the Faroe Islands is white with a red cross on the blue cross, it doesnāt really show up in the materials I have available, unfortunately. The Greenlandic and the Danish are red and white, just like the Canadian flag.

Very nice! Iām assuming these come off your CO2ā¦ Thatās very difficult to get right with a diode machine due to the rectangular beam. Do CO2 machines produce a tapered (relative to Z) cut? Iāve tried to do some critical-fit parts with my 20W diode and struggle with both taper and variable kerf.
Yes, it was made with my OMT60W, the good old Eleksmaker I use very rarely. I have had the opportunity to play a bit with a Longer 20 Watt and am impressed by its cutting ability.
It does, but with my 2" lens itās about 0.2mm on 15mm solid pine. With my thin flags (2mm) it canāt be felt or seen.
Hourglass effect, ( if thatās what you mean) should not be a problem up to a certain distance, on either CO2 or diode machines. However, I see relatively often that nozzle heads and diode heads hang hopelessly crooked on some machines. Models where you loosen and fasten diodes with 2 screws on the front plate, without a prism clamp or dovetail system, to be focused, are the worst. Half a degree off the angle and the cut becomes inaccurate. As I said, this also applies to many CO2ās.
Been wanting to try an inlayā¦ Do you do it like this trotek video?
What type of wood works best from your experience?
Material that gives a āhardā edge when processing. Eg. I have had good results with HDF/MDF and hard veneer is also fine. It is also ok with one āsoftā material, it must then have an antās hair more in kerf and a hammer 
Colored acrylic is very exciting to work with, but it requires relatively large and thin objects that are not overly complicated. Acrylic usually has a āroundā and a sharp edge per cut. Here it could certainly pay to play around with different lenses.
Nice.
I know you know this, but for others who may not you can get pretty close with your kerf offset by running a test pattern like this. Cut out the 10 boxes and when itās done squish them all together inside the frame and measure the gap they leave on one side. Divide by the number of squares and that gets you pretty close to dialing in your kerf.
Thanks Carl, this is one of the precise test and measurement procedures. The disadvantage is that it requires sensor blades to measure the correct distance.
For the little flag project, I use leftovers that I always save for such little things. I increase my kerf by 0.025 until it fits tight, it costs a little extra material but itās ādiscarded scrapsā.
Agreed, plus as you mentioned above you will likely get different results from different materials so itās not a one-size-fits-all.
Excellent as a starting point. I think most of us know roughly their kerf settings and then adapt them continuously from project to project.
My kerf is ānormallyā 0.075 mm, it gives me a tight fit in MDF. (distributed to both parts)
For flags, I have given the whole kerf to only the part that needs to be pressed in, 0.150 mm, and it fits perfectly. I have not tried using the offset function for initarsia, it should theoretically give the same result.

Small update againā¦
I am not completely satisfied with the usa`flag. I should have exchanged the 2 veneers, they would have fit better with the color and I have been too hard with the sandpaper, lower corner, right side.

Iād love to see Wales. My ancestral home. Plus, itās a cool flag. 
I will find it and you will get it
Should be a fun one. Interesting details.
oops you got me!, but Iāve made an initarsia with the LB logo, so the dragon in your flag will probably work too
This is for you, Chris!
Iāve started to cheat a littleā¦but I guess it still falls into the āInitarsiaā category

Brilliant! When the pieces get so small you need magnification and tweezers to work with them, I think you get a free pass. Lol!
The plates are only 100 x 50 mm, so the details are not easy to preserve. Iām glad you like it.
