This is a Laguna Drift Master bandsaw fence. I got tired of trying to set my bandsaw fence. Tap one way, tap the other. Could never get the fine adjustment I wanted. So when I found this, I knew eventually it would be the answer.
The installation requires some patience. I got it wrong at least once. All of the parts are VERY heavy, as they should be. Once this was installed it worked perfectly. As of this writing, December 2013, the fence has been installed for 5 years. I have never touched the install. It is still aligned and tight.
I find myself using the fine adjustment all the time. Simply engage the threaded rod and you have excellent micro control.
