Solving a 100-Year-Old Drill Chuck Issue

AI Thread Summary
The discussion focuses on an old hand-operated bench drill that has a centering issue with its three-jaw chuck. Despite cleaning and oiling the chuck, the drill bits do not center properly, raising concerns about the condition of the springs. Suggestions include the possibility of making new springs with piano wire and exploring other potential reasons for the centering problem. Additionally, there is a request for recommendations on where to source small springs in the UK. The issue highlights the challenges of restoring vintage machinery for practical use.

I have picked up a very old (possible 100 years of age), hand operated, bench drill. After cleaning years of dirt and rust off the machine it seems ready to go to work in the school workshop. There is a huge problem though, the drill bits will not centre in the three jaw chuck. I have had the chuck off and cleaned and oiled it. The three springs are present but I am wondering if they are worn. I know that it is possible to make your own springs with piano wire, and I have access to a lathe, but are there any other reasons why the drill will not centre? Also is there anywhere, preferably in the UK where I could get these small springs from if that is the reason why it won't centre?

Would be grateful for any thoughts on this.

Best wishes

Thread 'Query on Isentropic relationships (such as PV^gamma = constant)'

Hi all, I have a question. So from the derivation of the Isentropic process relationship PV^gamma = constant, there is a step dW = PdV, which can only be said for quasi-equilibrium (or reversible) processes. As such I believe PV^gamma = constant (and the family of equations) should not be applicable to just adiabatic processes? Ie, it should be applicable only for adiabatic + reversible = isentropic processes? However, I've seen couple of online notes/books, and...

Thread 'Dry sump pump issue'

I have an engine that uses a dry sump oiling system. The oil collection pan has three AN fittings to use for scavenging. Two of the fittings are approximately on the same level, the third is about 1/2 to 3/4 inch higher than the other two. The system ran for years with no problem using a three stage pump (one pressure and two scavenge stages). The two scavenge stages were connected at times to any two of the three AN fittings on the tank. Recently I tried an upgrade to a four stage pump...
