I'm looking to rivet two sheets of aluminium together with the pop type. I've researched that 3.2mm rivets should go into 3.3mm holes. (Who has a 3.3mm drill bit?) That's not a lot of clearance, which I understand is part of the concept to allow adequate development of shear capacity.
However, how do I practically do this for a row of 20 rivets? I don't think that I can pre drill 20 holes to a tolerance of +/- 0.05mm. Certainly not on my cheap 250W pillar drill. The "How to Rivet" demonstrations on line only show the basic use of a rivet gun on one rivet. How would I join two sheets with a row of pop rivets?
