BYO reader Travis Glazier builds the pump in a toolbox project from the October 2009 issue of Brew Your Own. Here is an excerpt from his blog at cnybrew.com:

"Over the past few weeks I have been working on following the 'Pumped Up Toolbox' project from BYO where author Ryan Locakard makes his pump a convenient carrying case for brewing odds and ends while also making it more mobile.  I found this project after I had been thinking about introducing a pump into my brew process for a while.

"Over all, I would say this project came out to about $220 give or take some money.  The large expenses were the pump, the shock buster outlet adapter (to keep from electrocuting myself) , and the quick release valves which will allow me to easily change the pump from sparge water to circulating my water for the chiller.

"Below is a video I made about the project.  The pump is working and the project was really easy.  It should be a handy addition to my brew process."
