Was not happy with my dimples with DRDT-2 and (dies from popular store 426-3 )
1) fit of rivet in dimple is not complete
2) dimple not crisp not well defined
3) nesting
Many people suggested C-frame makes it much better tried that no difference in results (for me).
NOTEs
1) Dies are not defective purchased 6 sets in total during 2 years period.
2) Reason for this post is to understand if
I have no knowledge in the subject ( most likely)
or
developer of this dies didn't spend enough time to tune them
or
because they try 1 size fit all solution
Please review and comment. I am new guy in aviation and hold only home school diplomas in everything I do. So please don’t shoot!!!
Here is dimple I managed to get using DRDT-2 and Modified dies
Material .032
DRDT2 preload material thickness - 1.25 turns
Drill bit used #40 Double margin
Hole final size Original dies 2.65mm -.104 Modified dies 2.70mm -.106
sorry fill better in metric
Modified dimple rivet fit
Modified not deburred
