I've only done pop-rivet work on a few occasions and the tools used were; measuring tape, marker, power-drill, pop-riveter.



The key thing we learned is to line up the fitting on the mast and clearly mark the holes. And after you do that CHECK AND RE-CHECK that you have the fittings placed where you want them. After doing that you simply pre-drill the holes. The trick here to ensure that drill bit you use is a hair SMALLER than the pop-rivet you plan to use. This will add friction to the rivet thus making it more secure.



It may also be beneficial to you to have someone with you when you do this. This sounds silly but just having someone there will help alleviate your apprehension.



I hope this helps !!
