Start early, take it slow, and show us plenty o’ pictures!
and consider Kyle’s advice including its book form in general
well I also opted for the “5 minute” express version of the wood glue cause with the side surfaces not matching absolutely perfectly and having never done this before I felt doubtful about whether I could actually fixate this with a rope I mean I was afraid a lot of pull on the rope could make the whole thing collapse and that the express version glue could grip sooner and better considering I would not apply a lot of rope pull pressure . . .
conclusions . . .
well having never worked with wood glue before I am surprised by how strong this stuff looks once it has dried I am sure the whole thing wouldn’t look as strong in case I had used my beloved superglue for this . . .
as long as the angles are what they should be the whole thing will not collapse under the rope even with the side surfaces not being absolutely smooth flat fitting together perfectly at every spot I am quite sure I could have applied a lot more pressure and so I would also go for a regular wood glue in the future and enjoy its slow drying properties . . .
I was in a haste to apply the express version glue so it would not dry too much already in the air and this was the main reason for messing up the whole dou with glue from my fingers I am sure a slow drying glue would have allowed me to avoid glue stains on the dou even on the first try of glueing a dou together
so after having had an already beautifully polished dou I got glue stains on it and I did not remove them completely I mean that would have meant getting into another like 10 hours of rough to fine polishing of the whole pieces again and I did not feel like having the stamina for that AGAIN so I kept some stains on there and here is a pants down picture of that

a wood finish oil is already applied and drying on that picture I will see how prominently the stained areas will eventually show up once the oil is dried and after a final cloth polish in a couple of hours . . .
as for the cleaning and polishing in general the finest grade steel wool seemed to work very well except for that I made the big mistake of also polishing the fingerboard edges of a 3 piece sao of course . . .
so I guess that is my conclusion and experience as a total amateur after the rough stuff is done . . . on to posting a picture of the assembled shamisen first time woohoo tomorrow I guess and then the work on the little things itomaki and koma and pickup remains after all I won’t actually skin this with stretched leather so whatever I end up using will likely also be a rather not complex thing that remains to be done . . .
