Then I would sand both blanks on 1 face and glue them next to eachother. Now sand the 2 opposite faces o[
]f the glue up flush and slpit in two with the band saw. That should give you two pieces of 1 1/2" wide by the length by 3/8" thick or close (blade kerf) since you've sanded the two opposite faces flush now you have two flat flaces to glue to eachother. Just reverse one to make the pattern that you want glue again and cut to desire size, drill the blank glue the tubes inside, flush the ends, mount those on the mandrel and turn to desired shape, finish assemble and enjoy.[

I hope this helps better than my previous post. The band saw still my choice. Less waste and it is safer, not to contradict with with chop saw user and table saw as well since I like them both.
