Reference the landing gear frame, I recall making up a redux flox mix and be
dding in the tubes, so that the load were better distributed. I intend on pl
ugging the ends, probably with timber dowels prior to drilling and final att
achment, so I can tighten the bolts fully without deforming the tubes, plus a
lso it stops CO2 ingress into my tunnel area.
