The 2 bar minimum means two atmospheres of air pressure as I explained earlier, not still air. You can estimate the 1000 degrees by when the oil stops boiling (this only takes a few seconds in the oil). Pull the blade from the oil and the oil that is still on the blade should ignite because 1000F is more than enough to cause the thin film of oil to burn. Immediately go into a container where the blade is somewhat enclosed - I use a sheet of tin about a foot long and curled into a cylinder about 5" in diameter. The edges of the tin cylinder are left open so I can slide the air nozzle up and down the length of the blade if I need too. The tin cylinder is nailed to my work bench next to my oil tank. Out of the oil, into the cylinder, blast with air from my compressor until the steel is barely warm. Be careful not to concentrate the blast on one side of the blade to avoid warping. I usually set my compressor to deliver 80 psi which is well over the 2 bar minimum ...
