I seal projects, if I'm concerned about and even stain, with shellac. I mix 1 oz of flakes with 8 oz of denatured alcohol. New batches about every 9 months to make sure it's fresh. This will dry in 15-30 minutes and needs a very light sanding, followed by getting the dust off with a tack cloth. (Don't shellac any project that's likely to come in contact with alcohol in it's normal use.)
The wooden gear clock I made I applied two coats of shellac as a finish, including the edges - nothing else on the BB stock. I used BLO on the cherry.
I'll join others I requesting pics of the project as you go and the final project.
