Thanks Jazzcnc.

Can anyone recommend a method of reinforcing my bolted connections on my steel frame. Currently have 4 m5 bolts at each connection between the steel box section, and after moving the machine around a few times during construction I'm certain the joints have moved.
I'd rather avoid buying a welder, so that leaves either more bolts, or glue.
There isn't much room for more bolts, so I think glue would be better, but I'm not sure what type would be best. Would a slow setting epoxy be a good idea?
