Nice to watch another video from You. Here drone flying is the major interest but making a chain tension part for the chain saw is waiting. Interesting and entertaining video. Being a child, several clocks were disassembled but never tampered with their springs. Some kind of instinct told it could be dangerous... About the chuck key. The teacher in metal works had a reputation of being hard. (On guy got thrown up on a 2 meter high cupboard when running the lathe backwards and not reacting on the noise.) The first lesson was just: "Don't ever leave the chuck key in the chuck. Then he pointed out a hole in the opposite wall several meters away, and told it was made by a flying chuck key. For newbies, it was the necessary "order". Maybe I fell back and pointed that out but hopefully in a respectful way. Still try to keep that in mind even as the lathe usually, not always, has a chuck protection not going down, prohibiting starting the lathe.
That I enjoyed. Only one bit of advice for your future reference, C Bennis Supplies & Services are worth your looking up, because they supply very good quality oils. I know there is also a clockmaker's supplier who services you are doubtless using. So there will be nothing wrong with the oil you have used. Just that, I use an ISO 22 needle oil with an additive to aid its being cleaned from clothing in washing machines. This is a synthetic oil & is obviously longer lasting than a non-synthetic one. This used on my collection of micrometers. Please do not ask me how I got into having around 40 mics & all the standards to keep them accurate!! I also use their ISO 32 Sewing machine oil as a slide oil because it has fabulous rust prevention properties & I find my Super seven saddle floats on it. Clearly these two oils have got to be kept well away from roller bearings, because they will break them.
OI Sunshine, Everyone knows the proper way to wind a spring is to run the chuck in reverse at 500rpm for 3.257 seconds with rubber gloves on and wearing a condom for safety. ARMCHAIR WARRIORS RULE !!!!!!. Best wishes Ade, Mal.
