I run my own business as a motor vehicle repair garage, I was changing the rear suspension unit, on an Alpha, when I put the spring clamps on the rear suspension unit, to compress it, as I was unbolting the rear suspension unit, the spring clamps slipped, and trapped my middle finger between the inner wheel arch, and suspension unit, splitting it from the knuckle joint, up to the end of my finger. As the spring from the rear suspension was now trapping my hand, between it, and the inner wheel arch, I had no alternative as I was on my own, than to pull my hand from between the top of the suspension unit, and the car bod. I still bare the scar which happened 30 years ago, and I still remember vividly the pain, as I was self employed at the time, going to the hospital, and not completing the repair, would have cost me money, so I strapped my finger up, with Elastoplast, and carried on, completing the repair to the car, as my priority was keeping the customer happy, and feeding my family.
