Are Tools related questions off topic? I think there are varying levels of tool questions and some will be suitable and some won't be. The original question I was going to ask, but thought twice about was:
What size air compressor (HP, Tank Size, CFM, etc) would be suitable for a home garage where I'm going to do small amounts of maintenance but nothing major? i.e. I would need to be able to use a tyre inflator and a rattle gun, I'd like to be able to do small amounts of spray painting but I don't plan to respray an entire car.
It's not directly related to Maintenance and Repair and isn't directly related to a maintenance/repair question, it could be a little subjective so I was unsure. Compared with a question like:
What tools will I require to change the front pads and bleed the brakes on a 1977 XC Ford Falcon?
(which I personally think is on topic, but I don't know for sure)
Is there guidance on this somewhere that I haven't come across?
