Truth be told. I did modify a Vice Grip to fit into some tight spaces desiring the rounded look to the back side of the solid rivet. First sanded and polished smooth both sides, then a shallow drilled hole as a centering point, then a rounded Dremel burr for final shaping. About $5 from Harbor Freight and a half hours work and save a hundred bucks - or more. I do have both though.
Oh I love it! Work well? I think this is the method I will use on the trailing edge. If Im using round head rivets Im guessing I need to dimple both sides...
It works fine. The leverage from vice grip geometry makes the difference in squeeze power. One challenge, though with rounded dimples on both jaws would be the centering top and bottom. A solution might be to use a very small drill - #60 for a drill through one jaw, then slightly into the other jaw then enlarge and shape.
