You can use them like a "crow's foot" or similar to a swivel knuckle ;)

I love the old tools because they are just so tough and you know they will out last any other modern tool and they generality have 50 years on the new ones to start. The very few wit-worth spanners I have are just the goods, solid and reliable. I even have a couple of 'stanly' hand drills, keep one in the deffer tool box all the time. Always reliable never goes flat.
My great grandfather in the UK was a bit of an inventor of various tools, devices and other things. Between WW1 and WW2 when costs were high, things were expensive and everyone was trying to make ends meet (a bit like today) he came up with a really simple tool to sharpen the old gilette style double sided razor blades (the ones with the jagged looking slot in the middle and an edge on each side). Of course your old cut throat razors can be sharpened with a strop but the gilette blades were a disposable item good for one or 2 shaves. His tool, made using a piece of glass, jewellers rouge (very fine polishing compound) and a carrier that held the blade and was pulled across the glass using a string. Apparently it only took a couple of "pulls" to resharpen the blade and he could get many months out of one side, then switch to the other side of the blade. As with all good ideas, it was "aquired" by gilette after he died and disappeared.
Amongst his other "credits" that he never received acknowledgement for was the aircraft inclinometer (to indicate sideways tilt, a common cause of aircraft loss due to uncontollable spins) which was a simple mercury switch that lit up a light to show excess tilt - very simple but very effective. He never wanted any money for it, just recognition as the designer. He was told it was a stupid idea and within months they were being fitted to aircraft and hailed as a breakthrough.
Interestingly, he also used to have a shop that sold valves for old radios and sold some of these valves (but was never paid) to the man who invented the television.
Nothing like homemade tools.
Yep, that's me. I try telling all the girls that. ;)Quote:

It is a Merlin head stud. I have a screwdriver made from one by my father when he worked for CAC in the 1940s.Quote:

I like this thread. I will have to go through both my grandfather's tools to find something like this. My Dad's dad was self taught, but had many inventions, some patented, others not. One was a steering damper for Indian motorcycles, my Dad has a letter from the NSW Police saying he will receive 2/6 for every one fitted to police bikes. He also invented a new type of headlight blackout cover, very useful in WW2, not so now, but he had it patented and received a small royalty from the manufacturer.
My Mum's father was a fitter machinist at Garden Island during WW2 and had a large collection of tools modified to do certain jobs, he also made many household tools such as carving knives from powersaw blades to a very high standard and despite being made in the 40's are still in regular use today.
