Vacuum Pump Project Update

It's alive. The vacuum pump is fully operational and boy does it suck. Sorry I couldn't help it. I got all the parts in the mail last week and started assembling right away. I originally planned a configuration similar to this one but once the parts were here and I started playing with them I ended up with what I think is a little more user friendly setup with things facing you and the valves right up front.

It took about 4 hours to build the tanks, put the box together and fit all the pieces together and then about an hour to reseal some of the threads with more pipe tape before it would hold a steady vacuum. With the valves closed, she will suck about 22.5 inHg and only drop about an inch overnight. I kind of wish the pump was a little stronger but no issues so far. After a few layups on the ski-boat I brought it home. What is the first thing I did with it? Vacuum bag my leg of course.
