Hi Dennis,
Rocsim says that a nosecone of this size would way 1/4 pound (.25
lbs). The only difference is that the lenth of the nose cone in Rocsim
is 9.5", and you mentioned 10. That should put you in the ball park
though.
Hope that helps,

Hi Denis,
To Answer your other questions, rocksim says a LOC 29mm motor mount, 7" long weighs .037lbs, a LOC 54mm coupler, 4" long, weighs .067lbs. As for the denstiy of 6mm birch, Im not sure if rocsim can do that. It can give you the total weight however for that thichkness. The weight of a ring of this size and thickness would be .0132lbs or 5.981 grams, or .211 oz, ( barely anything at all ).
Good luck with your first scratch build, ( Im doing my first scratch build too )
