Ready Steady Eddy

[EddyCurrent]

The reason I used box section for gantry sides was due to large strength advantage over plates.

I thought this might be an idea for attachment of sides to aluminium.



By welding a plate (with nuts welded to the back of it) about 6mm in from the end of the box section, I could easily file the box profile edges to 90deg. I suppose you could then fill the 6mm deep cavity with epoxy if need be. Maybe use 1/2" plate and drill & tap 4 holes instead of welding nuts behind a thinner plate.
Epoxy plan for gantry horizontal members will be fine.



1. Ball screw bearings moved to outside of frame or as suggested I might use BK/BF instead.
2. Support brackets for sides increased in size
3. I think you are saying that to fit the bearing blocks I need to drill through the ally backplate and use nuts & bolts rather than tapping the backplate and screwing in from each side with set studs ?
