Oil Wicks and Wicking the Lube Oil
Quote:
I crammed the felt in and the oil passed through in a few days, even though I started with 80wt gear lube. I have now heard that oil wicking is an art, with some wicks arcing up and out of the oil reservoir and over and down to the oil inlet ports. When I was a young lad and working in a very large company that made underground mining equipment, I watched the "oilers" come around to each machine in all seven of the machine shops, with their carts loaded up with all sorts of lubricants, applicators and hand tools. My being a forklift driver and shuttling parts through the mfg processes every day did give me some perspective on how raw castings and forgings got made into radial air motors and such devices .... but, sadly, no info was gained from those "oilers." More snooping needed..... I guess I might have to achieve a tighter fit, somehow, or change the wick type.

This comes at a good time, since I had exhausted all my resources and had not yet found the right diameter. I'll try them and see how close I can get. It has to fit closely or the oil drains too fast ....

cutting felt seals
Well, I once had to make some custom annular felt seals...purchased some wicking felt, then took it over to my friendly laser buddy. He cut the felt like it was butter subjected to a hot knife, or laser as it were...
Let me know, I'm sure I could finagle another favor...especially since, although there are no photographs of my fat a** hanging on that breaker bar trying to get the shaft to turn...good times! There are SAE grades of felt for lubrication and sealing. see: http://sutherlandfelt.com/resources/...ication-chart/ I have no connection with the company.

Thanks Hans.
Thanks Paul, This is a helpful note for me from that link: "Wicks for lubricating purposes are made by cutting worsted yarn into lengths about twice the height of the top of the oil-tube above the bottom of the oil-cup, plus 4 inches. Half the required number of strands are then assembled and doubled over a piece of soft copper wire, laid across the middle of the strands. The free ends are then caught together by a small piece of folded sheet lead, and the copper wire twisted together throughout its length. The lead serves to hold the lower end of the wick in place, and the wire assists in forcing the other end of the wick several inches into the tube. When the wicks are removed, the free end of the copper wire may be hooked over the tube end to indicate which tube the wick belongs to. Dirt from the oil causes the wick to become gummy and to lose its filtering effect. Wicks that have thus become clogged with dirt should be cleaned or replaced by new ones. The cleaning is done by boiling the wicks in soda water and then rinsing them thoroughly to remove all traces of the soda. Oil-pipes are sometimes fitted with openings through which the flow of oil can be observed. In some installations, a short glass tube is substituted for such an opening."
