Re:
Jim, this was years ago so memory of what I did might be faulty, I had a spinning rivnut in an old Cannondale hardtail frame.
No bottle cage just the wee bolt which was the top one in the seat-tube. I got a long thin screwdriver, I think, something with a thin narrow edge like a screwdriver anyway and pushed it down hard against the part of rivnut inside the seat-tube to jam it in the hole in tube then carefully unscrewed the bolt. Had skooshed WD40 on threads of bolt inside seat-tube and left it to soak for a while. If this hadn't worked I had thought of cutting a longish V notch with filed "grippy" bits, like a pair of pliers, in end of thin strip of steel to jam around rivnut inside frame to hold it.
You probably know this trick already, I then tightened the rivnut up using a longer wee bolt than bottle cage bolt with a nut and washer on bolt. Screwed bolt into rivnut till threads fully engaged, washer is fitted between nut on bolt and rivnut, hold bolt then tighten nut against washer/rivnut to crimp rivnut tight in frame.

Cheers, I'll have another look at it this afternoon, it's my Cannondale SR400 road bike frame, I could really do with having 2 bottle cages on it for longer rides!
The other frames with the same problem are... Another Cannondale! :facepalm: and a Trek carbon frame that I'll be selling but it'll be easier to sell it if I fix the bottle cage Rivnuts first (unless I royally f*ck it up and damage the frame beyond repair
).

I have a set of Vittoria Randonneur Trekking 700x35c tyres if they are of interest. New & unused. Having a bit of a clear out and the tyre pile could do with thinning out

Re:
Update on my foray into shorter cranks. Just got back from a bit of gravel riding close to home on a bike I fitted 150mm cranks to. Amazeballs is my verdict, easier on the knees, encourages a spinny style and in the right gear climbs well whilst seated. I urge you to try it, especially if your getting older and weaker which alas I am :roll:

Re:
Jeez Velo, next thing we know you'll be fitting narrow flat Handlebars and telling us all 3 x 8 is the perfect gearing
Meanwhile, stupid bottle cage bolt is still not budging, just spinning in the frame. Tried penetrating oil, pressure, leverage, heat, swearing... I've watched a few online guides, seems the answer may be to cut the bolt off and use a Dremel type thing to cut down the lip of the rivnut so it falls inside the tube, then fit a new rivnut.
And who doesn't like buying new cutting/grinding/noisy tools that make lots of sparks?!
