As I may have mentioned before, a good friend of mine builds electric motorcycles as a hobby. (He and I have a lot in common -- I met him in the philosophy program some years ago, and he's the one who got me into Strongman competitions.) He's been doing everything out of his home shop with hand tools, and was mentioning today that a fender he installed required 21 bolts. I suggested a mini-impact wrench and some impact sockets for a Yuletide gift to himself.
Since some of you may be looking for gift ideas for a man in your life (or a statistically-unusual but not unheard-of woman), here is what I use.
The blue one is the Makita XDT11. The smaller red one is their XDT15. The smaller one is a better choice for bikes because it also has three power levels, which can help make sure you don’t strip or round off smaller bolts/screws. The bigger blue one is great for larger axle bolts on bikes, or general work on your truck.
My son prefers the American-made Milwaukee alternatives; they're heavier, but he thinks also stronger and more powerful. My sense is that there's plenty of power already for motorcycle bolts, which are often quite small. If anything I think the key issue is to balance the power you bring to the task with the risk of damaging the equipment (e.g. the bolt-stripping/rounding I was talking about).
That boy is, now that I think of it, hard on equipment. There's an appropriate Corb Lund song.
Maybe it's one of those things you learn with age and experience.
