To increse reliability of staying glued, I always degrease the boron with thinners.
I then use a hypodermic needle through which I can pass the boron; the cup of the needle contains the glue ( best is Duco or UHU) so it precoats the boron as it goes through the needle and on to the wood. Excess glue is removed with a finger which follows the tip of the needle and pushes the boron in place on the component. It's the lightest method I've found and is very, but not 100%, reliable.

Yep, that reflects what I am supposing--that precoating is lighter than my present method. For 30" of .003" boron, I would expect 5-6 mg glue with syringe method. Thanks everyone. Think I see the direction to go, and may end up getting the Harlan do-dad, after my DIY instincts are defeated.
