My impact wrench is by Siliverline and was around £40. Still haven't used for working on car. But I can see it could be used for sharpening my vintage hand push lawnmower with a socket racheting on the bolt off the gear.
I managed to get hold of another breaker bar = 1/2" one but 60cm long with some sockets and extension bit. I am gonna put it in the boot of the car in case having to take off tyres.
We have noise pollution from every direction in the back garden from the neighbors gardens. I think one or two of them seem to run workshops. Every morning there are noise of electric router going or table saw. And then I could hear someone cutting grass with petrol mower, and then cutting hedges. Always something is going on over the back garden. And I also make noise with petrol grass trimmer, petrol hedge cutter and Bosch drills, and I also use power hose washing slabs and drives and windows.
Across the front garden, we have main road. So have lots of cars passing making noise, so we are not well situated in noise pollution, but have been here for now 10 years, and pretty got used to the environments
I was contemplating getting an Air Compressor, but then decided not to. I think my worry was space in the shed, and also expense of having to buy new wrenches and drills and other tools which go with it. And I read about it that they can get fairly noisy causing possible annoyance to the neighbors.
But I could see it would be real good tool to have especially for even cleaning tools and shed floors. Now I use petrol garden blower to clean shed floor, which is working OK, but it is also very noisy and ineffective in cleaning tools such as lawnmowers.
I was looking at CV joint working tools and also balljoint splitting tools on ebay. They were about tenner each, but wasn't sure would be useful in practice. Maybe I will get them when and if I get to work on the stuff.
