I worked sheardecks and the like for many years and then through no real fault of my own ended up on a busy line station. Believe me you can carry out simple tasks and you are a hero. Just quote the p/n of a 1/4 hilok 1/2, inch long and the lineys stand there open mouthed. You really can work as much or as little as you want (or feel like)in one day and you will have accomplished more than the average tyre kicker will do in a week. I find that the job is as challenging as I want to make it.
Wouldn't change it for anything!!!
