As mentioned in earlier post I found some broken frame rivets. As it was only two rivets I decided to try and replace them using heated rivets, pneumatic airgun ( rivet hammer) and some custom made tools seen below.
|Bucking bar to the left, rivet punch in the middle and the air hammer tool to the right.|
(old rivet head is placed in the tool to get a feeling of the accuracy)
|The rivet punch in the middle is made to slide over the air hammer tools to the right.|
|Air hammer toll assembled and ready to go.|
|I tried using a butane torch on a bolt to see how hot I could get it. Well it wasn´t enough so I had to borrow a acetylene/oxygen torch by a friend, man what a difference.|
