[DIY] Waste-oil-burner, what a hotty! (Gravity-Drip)

SO I build this little burner over the course of 2 months. The total building time really is only one to two days. Research and tweaking adds to the delays :P
The normal operating temperature at the vessel is about 300-400 degree Celsius. Hot air from the center pipe reaches up to 500 degree celsius. Once dialed in, the smoke clears and the burner is stable at 400'C.
Currently I run engine oil and hydraulic oil through it with a VERY nasty mix of all kinds of things that really made it smoke.
Ash will build up rather quickly and needs to be removed daily.

Tools I needed to build it:
Grinder, cut off wheel, welder, (plasma cutter was a huge help), pipe cutter, pen and paper, knife, measuring tape, flexible piece of plastic to mark around the pipe, wire brush, hammer (fav tool)

Oil consumption at 400'c about 1.5-2L/hr depending on the oil

Heats single garage from -5 to +20'C in ~30 minutes from startup

The design is a combination of many found on YouTube, the only idea of my own is the retaining system for the pan and combining the (to me) best ideas into a simple design.
Components used: One propane tank, some square steel tubing, 4" pipe 10 ft., 1/2 steel pipe (drip pipe), 1/2+1/4 copper line, one brake disk NOT VENTED (rear disk), steel cooking pan, some bolts and iron rod for pan mount.
Tools: grinder, plasma cutter, welder (MiG)

One thing I would do different in the future, make the pipe over the brake disk the same diameter or close to it, to prevent restriction and sharp bends.

Sry for the cheesy intro music, I felt like it.

Multiple 1/2 holes in mixer pipe, pipe is 4 1/2 inches long (should be longer)
