Adding anything inside is the worst place to add material. Add it outside. Stiffness is the cube of the beam thickness, so you really want to make it bigger.
Then secondary to making it bigger is to improve the shape to remove those parallel sides. So it you are just going to epoxy something on, try adding something like a channel section to the top or side of the beam. > On May 13, 2024, at 2:11 PM, andy pugh <bodge...@gmail.com> wrote: > > On Mon, 13 May 2024 at 21:51, Todd Zuercher via Emc-users < > emc-users@lists.sourceforge.net> wrote: > >> >> I'm less concerned about the actual stiffness and more worried about >> dampening the wobble. >> > > Maybe you could epoxy a smaller (aluminium?) extrusion or box inside the > existing one?
