That is a very ingenious use of the jig to ensure the correct placement for the supporting beams. Does it still get supporting beams on the other end as well - (I am not sure whether the cabin end is bow or stern !!! )?
Be that as it may - even unglued and not-sanded, those cross-beams already seem to have a very good fit!
As you wrote, SOS does not allow me to place 2 icons " the laughing and the love icons" . You are the best !!
The cabins are at the stern.
Wait..... there will be many beams to support the shields.
Cheers and your Sampan looks fantastic !!!
