I may be crazy, but I'm having fun so far.

With all the hundreds of fasteners I've been turning the last two days I find that my Makita 14.4 volt cordless impact is myábest friend. With a 1/4" hex drive It's really a little light duty for mechanic work, but it's rated at something like 100 ft lbs of torque and it's nice and compact. It's great for interior work and handier than an air ratchet or a 3/8 drive pneumatic impact gun. I haven't been able to run the battery down in a days use yet either and it probably uses less energy in a week than my compressor uses just to start up once. I imagine that this and the Milwaukee 28 volt cordless 1/2" drive impact gun (325 ft lbs rating) would be handy for trailside/roadside repairs too. At over $400 the Milwaukee is not cheap though. -- Matt
