Pressure Gauge Mod

After seeing this on the twitterverse, I was motivated to make some modifications to my current tire gauge.  A couple years ago I bought an ATV/Motorcycle tire gauge... it works, but not great.  It reads from 0 to 60 psi, which is higher than I need for my fat bike.  I would prefer a 0-30 gauge, but this one works just fine since it has marks at 1 psi increments.  The blow-off valve near the body of the gauge is a nice feature.  The worst aspect of the existing gauge is the push-on Schrader head, which makes it difficult to get a good seal on the valve of the tube.  

I also had a craptastic specialized pump in my junk pile.  I figured the 2 could be combined to make a better gauge...

After cutting both hoses, I found a random adapter (I'm still not sure what it was for) that screwed tightly into both hoses. What I ended up with is a much more useable fat-tire pressure gauge:

The new gauge screws directly onto a Schrader/Presta adapter, which provides a nice tight fit to the tube.  I may end up shortening the hoses a bit more though... sometimes it is nice to bring a gauge with you and a shorter hose would make it much more pack-friendly.  The blow-off valve makes it easy to accurately lower the tire pressure during a ride.  Although I usually just go by feel while out on the trail, so we'll have to see if this ever actually leaves the house...
