Need some opinions - I'm thinking of making a flex shaft temperature monitor

[SteveNelson46]

I have had 3 A machines before I got my B then added a C. I have NEVER had a heating problem with my flex shafts after the 3rd lubing with Lubraplate 930AA. It takes 3 times for it to really penetrate. Of coarse I do re-lube every few months. They run barely warm. I did replace the spacer spring on the B a while back.

I'm with you Clint. I have a "B" machine with well over 1500 cut motor hours (best guess as I haven't checked lately) and I still have the original cut motor and flex shaft. I've never had a flex-shaft over heat. Also, I've only lubed the flex-shaft maybe a half a dozen times in the last 6 years or so with the recommended lube. I do have spares just in case.

Speaking of temps for the flexshaft, I have been working on some ideas of a cooling coil to maintain a safe temp. Not sure yet exactly how to accomplish it, but my brain is buzzing with ideas. I don't want to know if it gets hot, I want it to stay cool.

Ed, flex shaft temp should NOT be an issue anymore. Use the correct lubricant and monitor it to NOT have an issue.

I do a "Pet the Snake" after the first bit cuts at bit change on a regular basis. At the first sign of any heat, I wait until it is finished and pull the flex and pull the core 1/2 way out and squirt a dime size glob of Chain Lube in the center and push it back in... Nothing special but it works for me. I believe the habbit of petting the snake and watching every bit touch is just normal operation for me. I have seen a non bit touch and have been able to stop and fix before making fire wood.
