From Paul: Thanks again for the time you put into this site and for sharing your knowledge and experiences in a constructive and informative way. I am new to woodworking and still learning about my tools. There are a lot of sites out there where folks seem to like to talk down to beginners rather than help them learn. You guys are awesome and I appreciate your help. Thanks again.
From Dwayne: Thanks I’ve been looking for this answer for the last 6 hours on how to hook up a unloader switch .. I appreciate your time and trouble answering my question.
From Jay: Thanks for your great site. I was able to find that the starter on my regulator had the hot wire slid off the spade lug. Simple fix (a bit of a pain to work in that small box tho). Great site!
From Shawn: Compressor had air over the piston. This site solved my problem quickly. Thanx, fix-my-compressor.com.
From Benjamin: Just to say thank you for this page, instantly able to diagnose intake valve failing, turned out to be a gasket blown through, 10 min job that saved me a whole heap of pain and expense.
