Did you use regular wood glue for your battons?
the laminate is glued with very strong contact adhesive. hella expensive bottle (40 euro, 50 usd)
and the battons are glued and screwd from outside in and inside out. glue is a type of no nails needed, can carry a elephant, filling type
i got some more pieces done, they took a lot of time, happy that they are out of the way!
i managed to make a mistake. i used up the laminate needed for the outside and left other bigger pieces not used. ordering new will set me back for 150 euro.
or i will use what i have and it will have a seam at the bottom (cab is 186 cm, laminate is 130cm+60cm pieces)
If i router off the sides it will be perfectly flush. and once the artwork is on there. who will notice.. i dont even think you will feel a seam.
if needed i could fill the seam.
