Default RAM rivets

Hi Adrian,

Were they 3/4" rivets? Presume you used a mag base drill. Did you remove the head from one side first? And did you use drills or annular cutters (Rotobroach)? Just wondering cos with my Grant hull out in the bush I used Oxy to slice off a head and we pushed some out with a pneumatic Rivet Buster when cooled when we had two people (and enough PSI). But then for the rest I needed to get out I cut the other head off too and used a packet of 3/16" drills and an air drill coupled to a modified drill press with some suds to drill the centres and then Oxy'd a "Y" so they'd collapse and then pushed the remains out with a hammer and punch while still hot. Tiny bit of damage to the plate or angle where I wasn't precise with the oxy. Interestingly 3/16" was the minimum drill size that would allow clear oxy penetration through the length of the rivet.

Regards

Alex
