    Earlier someone had mentioned problems with water in the oil. Easily solved with either a Mr Funnel (see home page - they advertise there) or designing a similar set up yourself. hust use a 5 gal metal pail like you did for your oil feed, put a standpipe in it and a drain in the bottom. The water will stay in the bottom and the oil can flow out the standpipe into a secondary bucket and it'll be water free. (Not sure what you can do about antifreeze)

    Some pics needed when burning if possible - love to see it in action!!
    Experience is something you get right after you need it!

    Yea, We have had a warm week. Last week the warmest it would get was 18 deg.

    I have always been concerned about the place I want to put the heater. It is a 4 foot area between my bench and a refigerator, we all like cold beer in the garage. When I did the test run I ran the oil over in the burner and do not want this on the floor, that is what started the pan idea and the shroud was just a little more protection for the wall.

    I have a 30 gallon drum that I will be storing oil into. I will have something similar to what you described. Water or antifreeze is not a concern as I have complete control of the oil that goes into my heater. I am a 25 year Caterpillar Technician. Today I will be draining 36 gallons of 30w power train oil into a clean pan. There is no chance water will be in that oil. I plan on using mostly 10w hydraulic oil as this area is what I work the most in. Often I will troubleshoot a hydraulic system and for some reason will have to drain off some of that oil or be required to change the oil and filter during some type of repair.

    I decided to go ahead and make a conical burner from aluminum. I had a 8 inch diameter piece of aluminum that was 1 inch thick. I just finished the 12 deg cut and still need to machine it for the mount. This will happen tomorrow. Pics will follow when it is done.

    Well it is not as warm as it was last weekend, 21 degrees. I wanted to show pics of the flame and the iron burner in operation. It was difficult to get the oil flowing. I am using old motor oil from our personal vehicles. It is very thick when it is this cool. With less wind it was easier to light. Here are the pics at medium burn. It is the best I could do with the oil flow under that temp.





    The next pics are looking down the air intake.

    The new aluminum burner, I will test this tomorrow. The first 1 inch from the out side diameter is cut at 10 degrees. The rest to the center is at 12 degrees.

    The aluminum disk is a total waste of time. The flame would die as soon as I shut the door. The cast iron and steel burner is what I will use from now on.
    I started when it was 18 degrees outside. I also put the heater in the in the shroud. The shroud works outstanding. The heater is at 700 degrees and the out side of the shroud is at 50 degrees.
    A dampener is a great addition to the system. It makes starting easier. I just shut it to a small opening and less air is pulled in to cool the oil. As the oil heats I open the dampener a bit more. To keep the heat at its full potential I have been running it about 1/2 open.
    I have been running this thing outside and keeping the oil flowing it tough below 40 degrees. The oil bucket cools pretty quickly. I think in the shop this will not be much of a problem as there is no wind, and the shop will warm, and warm the oil also.
    Yesterday I went out and picked up a 5 inch chimney system, my buddy is using a 4 inch exhaust, so I think I should be okay. I have a few more parts to pick up; I need to go to a heating and supply store to get them. They are a 7 inch roof flashing and storm collar.
    For those of you who think I live in a warm climate look at the sky in this pic. We are supposed to have snow tomorrow. Kansas weather changes this way all of the time.

    I have some concerns about the oil getting to cold to flow so I have ordered a 25 watt heating pad. It is made by Kats. They make larger units but, if I leave it plugged in I do not want to hold the oil temp to much over 100 deg. Ideally it would be held at 50, that is enough to keep the oil flowing. If my thinking is wrong about the temps feel free to chime in.

    I have been following your building and testing of the used oil burner with great interest. I have a couple of questions that I hope you may have the answere to.

    1. Did you ever consider putting some kind of window or peep hole in the door so you could monitor the burn without affecting the draft. You would also be able to watch the oil level in the conical dish to make sure your flow rate did not exceed the burn rate and overflow the conical dish.

    2. Rather than play with the damper in the flue to control the flame at startup why not add a damper to the air inlet pipe?

    In order to get a clean burn the air fuel ratio must be just right. If you just wanted a stove that put out a fixed amount of heat then you would need only one adjustment. Since you want to be able to have a variable heat output you need to be able to adjust both the fuel and air to get the burn smoke free. Just my 2 cents worth.

    I am really enjoying following along with you. Keep the information coming.
