So why didn't you use something like sintered bronze for the bearing? It absorbs and holds oil.

I've received enough request that will keep me busy for several weeks. So I'm sorry I can't make the offer free anymore. One question is why make one in the first place? A collector once said to me years ago; one of the problems with an Edison motor is that there is steel on steel friction with only the oil you can externally place on it. That in itself initiated the wheels spinning. I wondered if I could improve it. This bearing provides a continuous feed of oil to the bearing and reduce the constant need to oil it externally. Maybe it's crazy and won't make a difference. But I'm sending it out to several individuals to test it and see if it is an improvement. Or maybe it's because I'm too lazy to oil the motor as required! In 1963, I received my fathers Brunswick he played as a child. I was thrilled with it and began my enthusiasm for collecting, He would take me all over the city as I scoured for any old unit. In 1964, he paid $60 for my first Edison Standard (of which he only made $75 a week). I was stunned that he would make such a sacrifice for me. What is interesting is that he worked for Alcoa Aluminum. He was an avid inventor and came up with several improvements for the machines he operated. He was even recognized for several awards (unfortunately nothing financially). He passed away in 2011 at the age of 91 He was my best friend, hero and my inspiration. And we both admired Edison! Maybe a long explanation of why, but there it is.
