Driving a shaft out of a scrap ball bearing. Bearing has been on shaft for 58 years, well stuck. Don't have an arbour press. Bearing is sitting across vice jaws and shaft is being persuaded with a three pound soft hammer. One hand holding hammer, other hand restraining shaft.
A moment's inattention and the hammer slides of the end of the shaft and squashes the hand against a step in the shaft.
A cleanly cut semicircle chomped into the hand and blood all over the bench.
Wash the crud of the hands with Swarfega. Dry up on paper towels. Spray plastic skin on to slow the bleeding and stick a plaster on to hold it.
Sit down and shake for a bit and then go back out to the shed to see if the shaft needs cleaning up.
The shaft is not too bad, no rust, just a bit of skin stuck to it. The bench, however, needs scraping with a wood chisel to get the puddle of dried on blood off it.
Go inside and have a beer.
