OK, here it is! it was a doddle to make, and it works pretty good, more testing to be done in Daylight tomorrow.....
here are some pics of the various steps. took me less than 1 hour start to finish (ok I had a break for lunch to let the glue dry, but actual build time less than an Hour) enjoy!

bottle cable tied in position, awaiting addition of tubing, 250ml bottle, would prefer 150ml or 100ml

above: there is a piece of plastic lolly stick jammed between the cable ties to separate them and keep them firmly in the end of the tube, i am just enlarging the hole to allow better oil flow

here you can see the piece of brazing rod i used ( you could use copper wire or a bit of Coathanger)
this makes it easier to position the end "feeders", the inside edges of the "feeders, which are made from cable ties are grooved with a Stanley knife blade , 3 grooves lengthwise, to aid with the flow of oil to the tip


Above: the tap here is in the "ON" position, if the lever was straight up, it would be in the "OFF" position

In the above picture Inoticed the end was too near the sprocket so then adjusted it, that is why there is wire inside the tubing, so it can be bent and keeps its shape..... Note: Oil is visible just a drip, right on the very Tip, the grooves are working!
so far so good......... if anyone wants step by step instructions I will post all the pics ( about 35 and instructions) on instructables.com with a link


Above: Finished Installation.

cheers
