cylinder lubricators

hi everyone, has anyone made a successful lubricator drive, that has stood the test of time, and not given problems after just a few hours running? if so info, please....

Hi John Please post more details as to the end use of the lubricator. I.E. Lubricant amount and viscosity continuous or intermittent delivery Etc.

Hi Eric, the type is for the 5" g 9F. and is of the ball and wedge, clutch drive. I have made several,, they run but are unreliable in a short time, either slipping and no delivery, or jamming up. so I am going back to ratchet and pawl.. you can see one being built on utube,, on account. No23mk2. part 66, 67, & 68 john

Hi John Working in industry I worked on machines that had a sprag clutch fitted. They come in all sizes with the same dimensions as a Ball Bearing. possibly one of the very small ones would fit the bill. Took a peek at you tube

Not a good idea to make the outer in  any old steel it will FAIL even in a short time. The whole thing needs to be made from hardenable steel and properly hardened and tempered. The units I worked on had given thousands of hours service in harsh conditions.

I have made a couple according to the drawing by S. Purinton in ME. It's just a wound spring round a 1/4 shaft and another attached to the arm. The spring grips one way and releases in the other direction. Works very well and costs next to nothing.
