Wanted: Flue pipe and other oil burner bits.

I also need some form of regulator to control the flow from a gravity fed tank into the burner. Smaller pipe size the better, but needs to be able to flow cold oil at approx 1 drip per second.

make it !
i have before
block of alloy threaded bar and a valve handle
drill through the block 4mm.
drill 10mm @ 90 degres into and past the 4mm.
drill and tap m8 into the 10mm via the 4mm.
grind point on 8mm threaded bar.
the point sits into the 4mm hole restricting the oil
