Nice to see you back on the forum!
Sorry I don't have any recipe for chain oil like rendering chicken fat and one part olive oil but for snake oil, yes.
I use PJ1 it comes in a spay can like wd40 with the tube I'm sure that you know what I mean. I use it on all my chain driven bikes which are sport bikes. They have a product called Black Label it gets thick and is like tar but it gave me over 30K miles on my last chain on my 165 hp sport bike. They also have a clear product that I use.
Never ever wash your chain in any solvent, gas, wd40 etc. It dries out the rubber "o - rings" on the chain. Use a mild soap and brush I use hot water and dish detergent.
I lube my chain every 300 to 500 miles or every other time I take it for a days ride.
Would love to see how your project is coming along and some pics would be great
