Thx DLP.
The oil is in an old fuel tank, hung from a tree, thru a 150micron filter, then the 1/4 in ballvalve (open just a crack) thru 1/4 in copper down the old flue (now makeup air) tube, reduced to 3/16 and drips on to a cone-bevalled steel plate. See link below:

It works good! Lotsa heat! Cost me aprox $50 in spare parts, but for this design to work you NEED to machine the "burner pot", which "Granpa" G made for free.
Cheers, G.
