I bought both the Craftsman DA sander and 100lb Capacity Sandblaster. I lost the paperwork/instructions on both. Today I finally had a chance to get out in the shop and work on some bodywork, and tried both tools and was thourghly disapointed with both. I am hoping that someone can tell me how to configure either one or both to get some performance out of the tools. I know the max PSI for both but past that I am clueless! Thanks!
