I've got the Main Squeeze that came with my RV-12 tool kit from Cleaveland. It works great. I've had a couple situations where the 3" yoke couldn't quite get perfectly straight to make a perfect squeeze, especially next to a flange combined with another piece. Should I buy the longeron c-shaped yoke, or a longer yoke, or maybe purchase a rivet gun kit, or maybe a combination? Just trying to make life easier without excessive spending. Thank you
