Do you have a Dremel with a cutting disk, or a friend with one? 1/8" tubing is available in many hobby shops and hardware stores. You can get a slightly larger size, but don't, you need the tightness and the spiral cut allows it to easily but firmly screw on.
Take the tubing and draw a spiral about 1 rev in 1/2 inch and then make the cut little touches at a time. Add about 3/16" of un-spiraled and cut it off. Bend the male spade over 90 degrees. Solder it in without filling up the spiral section. You can possible make it easier by adding a bit of height to the uncut portion if height in the machine allows, perhaps 1/4" instead of the 1/8-3/16" described. Fit the spade partly together so that you are not fighting it on the post. Partial fit and then remove spade from the piece that you made and screw it on.
Very easy to make it over if the first trial does not work. You will have 1 ft of tubing.

That's a good fix/solution Fred! I've done this with other electrical wire joining work (not brass of course, I'm just comparing the example) called a 'union'. You may be able to silver solder the brass end onto the end of the terminal post. I can't remember what the metal is though, & if it's some sort of steel it should be able to be low temp brazed.

Thanks, Craig. The Gaggia post looked like stainless, not tested and not sure about Silvia. The post and element below may heatsink solder a bit. I would not want to solder or weld while it is together, but that may be my inexperience. It is screwed on firmly and I think will work. You are going from a spot weld to a circumferential fit of brass, I think enough surface per the reference. I still think that the actual spade connection may not be more conductive than the spiralled brass.
