Negative Positive
Title: Some invalid data
Review: This book was my first readng on dust collection. My first impressions where very positive because the book was short and clear.However, after building my first dust collection system (and spending quite some $$$) following the instructions of the book carefully, I realize to my dismay that my system was not even as efficient as my shop vac. (I could have bought a shop vac for each of my tool for the price of my installation).After reading more litterature on the subject I realized that this book contains a lot of errors and describe system that are appropriate for hooking up 1 or 2 machine sitting next to the dust collector.The numbers describe to estimate the power of your dust collector, the size of your pipes, the CFM requirement of your tools are very underestimated.Some illustration are also showing stuff not to do like having long run of flexible pipe.
Is the review positive or negative?
