My recent acquisition of a pump oiler that worked AND suited the original ball type nipples that festooned the 13 was reason enough to remove the more conventional nipples I'd installed and reinstate the originals. I think the Wanner oiler is larger than the original supplied with the mill. One nipple could not be accessed properly to ensure adequate delivery of oil. When I installed the Alemite nipples I used a 45 degree version in that location.
Greg Q identified the original ball nipple as being a K type and kindly provided me with a link to a German manufacturer. A search on German Ebay for kugelschmiernippel :D proved fruitful. The K type nipples were not too expensive and one seller also had 45 degree offset nipples. But those 45's would not fit without some modification.
So rather than fool around checking the lathe's tailstock alignment this afternoon, I made a 45 degree offset adapter from some phosphor bronze. After milling and tapping the angled outer end, I had considered a number of ways that I might have been able to remove the projecting elliptical end. Freehand against the sanding disc, even free-er hand with a file, some ambitious setup on the rotary table....or what I ended up doing. There is some manual file work still required but it worked out OK. The nipple is now readily accessible.
The paring was real easy. The cuts were light due to the delicate hold the M6 screw had in the threaded hole only 5mm deep. The body of the adapter is 9mm in diameter. I simply rotated the chuck 180 degrees by hand.
One of the photos shows the Alemite version. The ball nipple's 6mm thread was too long. The nipple could not be tightened without closing off the rear of the oil hole. The thread could not be shortened because the outer end is swaged to retain the spring and ball.
