Well here's what I've been doing this weekend other than dodging tornadoes.

Started on my waste oil forge build. Made a table with oil jug support, put it on casters so I can roll it in and out of garage. Cut and welded up the metal bits, still have to weld and fab up the stock support for the front door and weld in a few pieces of wire to hold the insulation onto the doors.

The burner is based on "The Brute" off of backyardmetalcasting.com. It's a 1 1/2" x 17" black pipe with valve to control air, a 9" x 1/4" black pipe to drip the oil into the burner tube with a valve to control oil flow. Just mainly waiting on my Satanite to finish installing the kaowool. Here's a few pictures and I'll add more as I go along.

Here's the oil feed tube, it's 1/4" black pipe cut off at 45 degrees at the end.



The burner tube. 17" of 1 1/2 black pipe with the 1/4" oil feeder tube entering it at 45 degrees. The end of the feeder pipe is about the middle of the burner tube.




Forge body. 10"id pipe 15" height, doors, burner support visible in the bottom of photo. Waiting on Satanite to install Kaowool and a few fittings.

 
I was wondering if any one has made any progress with this. I Look forward to seeing yours done. Mine was coming along but I had to redesign it some. I have too many side projects at the time and the cold has kept me from doing some of them. I have access to over 150 gal. of waste oil so as soon as I get mine done I can start saving some $$$
Good luck and keep us posted.
 
Buddy in the local forge council has a 55 gallon drum he says I can have and my brother is a chef so I can get the oil from the fryers too.
 
Hello gent's, are either of you heating and filtering your oil prior to injection/ drip into the forge?
I am building the same type as yours and will be going with the pre heat and filter, basicly using the idea from the biodiesel still/ old hot water heater and an military fuel filter with home made filters, still gets down to 3-5 microns, doing this I think will make for good flow in cold weather and the filtering keeps the nozzle to positive flow and easy adjustment.

What do you all think?? Thanks.Dave.
William, I design as I go along, change is good, aye?
Will, your's is looking good, how thick is your wool going to be in the door and the forge body?
 
I plan on filtering through a sieve and then a cloth before going into the bucket on the forge but not too worried about pre-heat because I live in Alabama and it's usually warm here. Also using large bore tubing should prevent most any clogs that get passed the simple filtering I'm doing. I'm also using clear tubing to see where/if any clogs happen.

The guy that designed the burner I'm using originally had pre-heat and propane ignition but he boiled it down to the simple burner I'm using. I think it's about the 8th design in the series.

I'm using 1" of kaowool with a coating of satanite on the walls and 2" top and bottom with a heavier layer of satanite on the floor.
 
Will, Hope you have this new forge down in the storm cellar for safe keeping. Can't wait to see it in operation. Bruce Evans has talked about building one of these also. Please let us know when you get it working.
 
More pictures as promised if anyone cares lol

Forge completed just waiting on satanite to arrive




Stock holding fixture, 2 pieces of 3/16 x 1/2 mild steel that are bolted together and to a piece of angle iron on the forge body so that they swing.

 
Got it up and running today, lit 2 pieces of charcoal and chunked them down in the bottom. It smokes like hell until you get the fire right. After shutdown, leave fan running to burn out rest of oil in the forge body.

Here's picture of the whole rig up and running:





Picture just of fire :)

 
I'm actually using waste motor oil. It's smelly at the start but when you get the fire right the smell goes away. If you don't leave the fan on after you shut down it get smelly again :pukes:

Dunno about the pictures, they're working for me. I'll try linking with a different code.
 
Will, With you being a knifemaker you should be able to post pictures using manage attachments right off your hard drive. These links are not working for me.
 
Yeaaaaaaa....Glad to see you got it running....Now you gotta share all the particulares about setting it up..LOL

Heat is hotter than propane. I ran the forge for an hour and can't really see a change in the amount of oil in the bucket.

Dunno what you want to know about set up. It's 2 pieces of pipe with a blower at one end. The oil feed tube enters the burner at a 45 degree angle and the end of the oil tube is cut at a 45, the bottom of the tube is about in the center of the burner tube.

I'm using valves to control air and oil flow, after the burner comes up to temp (takes about 5 minutes or so) I can add more oil and cut back on air. I crank the oil up until I see it hitting the side of the forge body then back off. I'm still experimenting with air/oil mixtures but am getting a nice fire that produces minimal scale.
 
What is the heat?? Do you have a thermocouple?? I am very interested in this and am building one myself. Mine is going to be horiz with an oil heater pump on it to vaporized the oil. I needed to get a salt pot up and running so that is what I have been spending my time on.
 
No idea what the heat actually is but steel comes up to forging heat faster than in my propane forge with a venturi burner. According to the btu tables on backyardcastings, oil has the potential to burn a lot hotter than propane. Those guys use these burners for home foundries.

A salt pot is my next project once I get over the fear of setting myself on fire.
 
There is a bunch of BTU potential in oil. That is why I wanted to augment my propane forge with oil. Have you tried any forge welding?? That is what I really want to get it going for. Using #100 of propane every 3 days is getting expensive. Just went down today and paid $65 to fill one tank up. Oh well that's life I guess... I do like a blown forge over a ventury though. I can control mine with very finite adjustments. I really need to get this thing going. Next project I guess.
