That is the hammer i used for the job and it worked very well... bigger hammer would have been easier, but its very achievable with the one i had. if you are countersinking the plate Jim i used a 45deg maystag countersink bit, and created a cut into the plate with a diameter of 16mm. the setting allowance for my snap for the armour from memory was around 13mm. This is the length poking through when the rivet is seated. so for example on my carrier the side armour rivets i need to consider 5mm for the frame rail, 8mm for the armour and 13mm for the setting allowance, so the dimension for rivets for the side would be no less than 3/8 x 26mm (button head) i ordered them longer then made a collet on my lathe to the correct setting length, then turned some rivets down in areas where the countersink was not quite as deep etc.... I could chat on for ages mainly because i am a sad sack... but partly because the thought of rivetting a project for the first time is very daunting for folk to want to undertake..... having done the job i can advocate everyone to try it !!!!!
