Earl:
I looked up the McMasters catalogue that was suggested somewhere else in the chain. They do have an 18 inch oiler but it has no valve. Is the valve necessary or an attraction? They also have a 15 inch pump type with a flexible spout, but don't know how much pumping it would take to oil a K-36.
I looked at the drawing that I have and have some ideas of how to construct an oiler out of copper and a few fairly standard fittings available from your friendly Lowes store. I will be in Chama for the "C" week with the Friends and if you have not found something by then maybe we can talk about a winter project here in Southwestern Ohio.
