Removing Dent in Thin Steel Top Tube

your marin dent looks more severe in that it is deeper in a smaller area.,
that kona dent should pull out, this is how I would attempt it. use epoxy glue to attach one or more small bolts.
place a piece of wood along the tube and a strip of steel with one or more holes on top - the wood spreads the load over the tube.
the bolts will line up with the holes in the steel strip, put on a nut and wind out the dent.
the epoxy or paint may give way but you have the bolt attached to a plate.

Sounds like an interseting way of pulling the dent out I was thinking of rolling blocks but this sounds better
You dont have any photos of this methid do you...Pretty sure I have a rough idea from your desription better photos would make it clearer or a link with photos
Cheers

Been mulling this one over too. I would carefully remove the paint from the surface of the dent and clean it properly so there is no dust, fingerprints, grease etc to affect adhesion.
Then use 3M™ Scotch-Weld™ Epoxy Adhesive DP110 from Vikingtapes.co.uk to glue a small piece of stainless steel Cavitation Plate Pad - 3/8 You can grind or dremmel it to fit the dent but best to go for the contral 1/3 epicenter region of dent for maximum effect.

Leave it dry 24hrs in warm place using gaffer tape to hold and to get a really strong bond.You don't need too much glue. When dry attach a plate with a hook on it then hammer against the plate to pull out the dent. Maybe the supporting wood and bolt ratchet plate method would be even more precise and controllable.
Its easy to remove the 3M glue without damaging the frame by using a heat gun 200 deg F or so. It won't melt the frame. The glue will go flaky and be easily scraped off with piece of wood so no scratches to frame. Redo if necessary,
I think it would also work on small dents to Ti frames.

what appears to be using silicone then using silicone remover to unstick the cups. diagram of what i am on about is below.
here is simiular idea but using a lever

the automotive dent pullers use a small slide hammer and stick plastic tags on with a glue gun, quick pull then snap the tag off. works well on hail impacts.

I've had some success in the past by hammering / tapping on the top or bottom of the dent. Use a metal working hammer lightish weight to tap the raised area where the paint has chiped off in the OPs picture, whilst holding another hammer or a dolly (if you can get hold of one) on the bottom raised bit. Again the lower section of tube where the paint has chipped off. This serves to push the dent out reversing the impact. You cant remove the dent completely but I've used metal filler on the remainder of the dent to bring it back to the shape of the tube. I've done this on a Kona, an on-one and a road frame all with simular dents with good results. Once finished you wouldn't know they had been dented. You'll need to lightly sand the filler and surrounding area to shape the filler and will need to repaint the section after.
