Possible, but ideal? Dunno. Screws threaded into a relatively small amount of what appears to be aluminum, acting on a thin wall chrome plated tube... might be better just to drill all the way through and bolt the thing together. Even did I use the set screw solution, I'd still use glue, expecting the screws to add to the mechanical bond.
Nick, I wrote an English firm, specifying a chrome plate into aluminum housing joint. Response is below. It appears to require a specific gun with mixing nozzle, and so it might be an expensive purchase. Not sure.
It seems to me that no matter what you do (unless you follow the rude suggestion to run a bolt through it), the base is going to need to come off, because either you will be threading it per Cliff's suggestion, or else you will be cleaning grease that has most probably drifted into that joint from above. Once it is off, you have options. A high strength epoxy would work if you can rough up the surfaces adequately, particularly the chrome tube. Epoxy won't do much if it can't get a mechanical grip. If the fit is close enough, an anaerobic glue is a good choice. If you can find the stuff below (whatever it is...) at a reasonable price, that might be the way to go.
