I'm glad I could offer some advice.
I don't have the link to the other thread, but I suggest that you just press hard over a very sturdy surface (I put my mat over the leg portion of my table). I don't try to twist the tool at all.
For me, I stand up, put both my hands on the top, lean into it, and press. It works every time on every type of eyelet I've tried. Rarely, I will need to hit it with a hammer (usually if I'm doing a lot of setting I will need to do this to make sure since I get tired

). I hope this helps.
