I unfortunately need to poo-poo on the Pinbits tap-riviet kit. It was IMPOSSIBLE to get those stupid rivets to hold. I tried "light taps with a small ball hammer", as recommended by pinbits. NADA, no "roll over" on the rivet coller. I then upgraded to WAILING on the rivet (fearing the entire time I'd crack the NOS ramp I was installing light domes on). Wailing got it to stay in place... until you sneezed on it. Seriouly, if I even touched the "attached" rivet, the stupid thing would let go. I tried using a good 5 or 6 different rivets thinking I had one or two defective parts... not the case.
I can absolutely NOT recommend these to anybody. If you don't want a rivet press, stick with pop-rivets.
