I don't have an air compressor so I was using a 3/8 drill & a 1/2 impact on the bolts on my floor. Found that the Philips screws where 3/4" long easy to get out. The 1/4" lag bolts I used the impact to remove or break off. I've been thinking of renting the air tools and compressor when I need the use of air tools, but the rental is just under the cost of the air compressor and tools. Might be useful to have on the road as well.
heres the thing with air tools... I once thought how cool iut would be to have them on the road.. and after all my bus has a built in 13 cfm air compressor..
then I realized if im using air tools im probably fixing broken stuff and the bus probably isnt running... so id not get much use and carrying air compressor inside is huge..
other thing was that if im working under the hood there often isnt room to get air tools... if im doing a major teardown im likely not doing that on the road so id be near home where my air compressor is..
I have a 30 gallon harbor freight comopressor I bought 10 years ago.. it works for most jobs but wont keep up if im wire wheeling or grinding tons of stuff..
its uch easier to get 120 volts and have a mild electrric impact wrench and a grinder for conversion work.. an electric impact isnt quite as good as air but its not bad...
cordless ones are worthless.. i have a cordless dewalk grinder and useing the high capacity batteries I can charge as fast as I use them.. but the cordless impact didnt have the torque to take things apart any better than me with a hammer on a wrench or using a breaker bar..
