We have a Cassese 910 at our shop and a thumbnailer. I've been framing for two years and have always used the thumbnailer. I want to actually start using the Cassese but it's in need of a tune up and or clean up from sitting so long. It doesn't seem to hold the frames tight enough and the pressure of the foot isn't enough either. I guess what I need to know is how to go about making sure it is running in tip top shape. Thanks for any replies. Jay
