Subject: Cutting Beman Carbon Spars

Can someone enlighten me as to the guidelines for cutting spars?  Specifically,
In the plans I have for a Standard-200 or Team light, they specify long spars
which would require joining of two shorter lengths.  I intend to use Beman
strong/light spars which come in 32.5" lengths.  Is there any limitations
on how much may be cut from a spar?

Thanks,
Scott

If the spar is a straight construction you can cut it anywhere
along it's length without a problem.  Some spars are tapered
internally to increase stiffness and reduce weight, they should
not be cut except at the reinforced ends.  SkyShark and G-Force are
in this category.  Beman products are all straight walled.

If you must cut a rod with tapered or very thin-wall construction
be sure to epoxy a plug of some type into the cut end.  This will
keep it from being easily crushed.
