Hollow punches never work well for me — I usually find them too blunt to use on plastic card unless it's very thin, and they tend to leave much too ragged edges for the discs to be useful
Making discs to glue to models. It's not like I would use this all the time, but over the last few years I've often enough found myself needing to make discs of larger sizes than I can make with my modelling punch and die sets (one by RP Toolz that goes from 0.5 to 2.0 mm and one by Historex Agents that goes from 0.65 to 3.9 mm), that I was looking for something with bigger sizes of punch. For example, for
this model I made the discs on the sides as well as the ventilator between the hatches using this tool:
To be honest, if I had found one half the size of this, I would have bought it instead — I can't see myself needing the larger sizes at all (though the commander's hatch on that same model is made from a 20 mm disc and an 18 mm disc I made with a circle template and a needle … I could now punch them instead if I wanted to make another
). There
are sets with fewer punches on Amazon, but they were all either weird sizes (not-round numbers) or skipped too many to be useful (like having only 6, 8, 10, 11, 12, 14 and 16 mm), not to mention those were only around 10 euros less than this one that has both round numbers for the sizes and doesn't skip any.
Thanks for the compliment, but I wouldn't go that far
