Geoff,
Another thought is the condition of the boron as a bondable surface. Has
anyone thought about prep? How about a bit of acetone or MEK as a "wipe"
on the material using a small soft artists brush? Then use something other
than your fingers to handle them afterward. Also, the tools need to be
clean too. The idea is to keep the bonding surface clean of anything like
oils or perhaps some treatment applied to the boron in the manufacturing
process.
With the use of many new space age materials it's been my experience that
when bonding any solid surface material or porous for that matter that
surface prep is extremely important. Even scuffing with a grit paper on wires
and shiny surfaces. We probably do not pay that much attention to it as we
have never had to before.

Just a couple of points which might be useful Both Duco and Ambroid are
good for general construction. Duco has a better grab factor and is much
more effective for seaming sticks and booms. Use Ambroid for Stick bracing
.Duco permits creep with 0.001 tungsten wire under tension. Increased stick
bow without realising it. Not good. Tan2May99
