@chargepositif That is one way to do it, but it is a long prosess. I think it is around 1" (from either side of the log) drying pr year if you do it like that, so if it is 4" it takes ruffly 2 years to dry (naturally) quicker if you have a dryer. I just sliced it in ruffly 8-10 mm and lay them out to dry. Only had 5 crack of 250 disks after 4 weeks of naturally drying.

@space670 That looks great! Such a cool design, and that it just happened to come out with the light & dark is sweet.

I had a woodworker friend suggest cutting logs, with their bark still attached, to a "reasonable length," so maybe 50cm - 100 cm, then sealing the cut ends with paraffin wax (or equivalent) before setting aside to dry. The wax seals the "easy" route for moisture to escape, forcing it out slowly through the bark, and preventing cracks.

@space670 Cool effect tho, pretty dope dude.

Just one setting on engraving , it is hard wood. So that might affect it.

Wow this looks great. Did you do separate settings for the inner design and outer ring? Or did it just work out like that?
