Worked over several days to start riveting parts. I worked on getting the VS spar and then the framework together. The first rivets I did were with a hand squeezer. Wow was that a lot of work to mash them puppies down....But I got my pneumatic squeezer this week and finished the VS skeleton with the C-Rex! Man is it easy to put in rivets with the squeezer. The first few were a blast it was so easy. It was well worth the money.
