Small air tools, grinders, etc have served me well --- they were cheap and cut some stuff for me and I still have them and use them occasionally. I have a 1/2" HF air wrench I use for just lug nuts, and it works just fine every time. I dont use my stuff heavy so I'm ok with a cheap tool now and then.
On another note - I really enjoyed your video. Your Dad must have been a really good man- especially so when I see how good a Dad you are with that wonderful little boy of yours. Thanks for sharing your family story ----
