Archie Zietman Posted December 24, 2007 Share Posted December 24, 2007 Hello! I just tested out my wvo forge, and it works beautifully. It used about a quart of old canola oil in about an hour, and can get up to bright yellow heats with ease. With it, I can work several pieces in the forge at once as well. Only drawback is that it is rather loud. Just figured I'd post about it, Merry Being, Archie Quote Link to comment Share on other sites More sharing options...
Blacksmith Jim Posted December 24, 2007 Share Posted December 24, 2007 Sounds really interesting. Got any pictures or a more detailed explanation of how it's burning the waste veggie oil? Quote Link to comment Share on other sites More sharing options...
J W Bennett Posted December 24, 2007 Share Posted December 24, 2007 Archie, It's not nice to tease on Christmas eve. Pictures and show an tell and maybe a BP are in order. John Quote Link to comment Share on other sites More sharing options...
jimbob Posted December 24, 2007 Share Posted December 24, 2007 Are you using used cooking oil? or just any old oil Quote Link to comment Share on other sites More sharing options...
Archie Zietman Posted December 24, 2007 Author Share Posted December 24, 2007 used cooking oil, but it'll run on motor oil if you want it to. I'll put a blueprint together. Quote Link to comment Share on other sites More sharing options...
Archie Zietman Posted December 24, 2007 Author Share Posted December 24, 2007 Here's a pikkie of the forge right before the run, it don't look too different, except that the metal is now matte black around the holes. I need to plug up the area around the burner, unburnt oil vapor was coming through it, at varying rates. It also has a slide-choke on the T-coupling, to manage the air, though I have just kept the air on full blast and just monitored the oil with the needle valve.

sdalcher Posted December 24, 2007 Share Posted December 24, 2007 Archie, How did the blower pipe fare temp wise? Did it get hot? My propane burner stays cool because of the compressed gas leaving, just wondering how much of a difference there would be with a blown burner. Thanks Steve Quote Link to comment Share on other sites More sharing options...
Blacksmith Jim Posted December 25, 2007 Share Posted December 25, 2007 Is the oil coming in under pressure? What is the apparatus you are using to deliver the oil into the forge? Quote Link to comment Share on other sites More sharing options...
Archie Zietman Posted December 25, 2007 Author Share Posted December 25, 2007 Gravity. I attached a diagram, I'll get pictures when I use it next, on Wednesday. Quote Link to comment Share on other sites More sharing options...
Blacksmith Jim Posted December 25, 2007 Share Posted December 25, 2007 Archie this is great! Thanks for sharing How are you controlling the rate of flow of the oil? Quote Link to comment Share on other sites More sharing options...
Archie Zietman Posted December 25, 2007 Author Share Posted December 25, 2007 I have a 1/16th inch diameter needle valve to control the flow, it varies a bit with the amount of oil in the tank pushing it through, but not too much, I just keep it topped up and its' fine. Tomorrow I'll get running pictures. Quote Link to comment Share on other sites More sharing options...
hdwarner Posted December 25, 2007 Share Posted December 25, 2007 where did you come up with this idea ? Quote Link to comment Share on other sites More sharing options...
Archie Zietman Posted December 25, 2007 Author Share Posted December 25, 2007 Well, backyardmetalcasting.com has a lot about separate body burners for foundries, they get hot enough, so I figured, why not try, but have air and oil burn completely in one chamber, so that there wouldn't be any heat lost, nor would there be the fiddliness of a huge separate body insulated burner to hook up to the foundry, a whole lot more compact.

rusty_iron Posted December 26, 2007 Share Posted December 26, 2007 Gday Archie Thanks for sharing. How do you light your burner? Do you have to pre-heat the chamber to get it going? Did you buy the needle valve new or did you salvage it from somewhere and if you did, what sort of machine did it come from?(so those who would want to make a burner like yours know where to look). What sort of shut down procedure do you use? Questions, questions.... they never cease... Regards Rusty_iron Brisbane, Oz. Quote Link to comment Share on other sites More sharing options...

rusty_iron Posted December 26, 2007 Share Posted December 26, 2007 Gday Archie, Thanks Mate, it helps a lot, thanks very much. Looks like an interesting project to build. No home depot here, but I'll find a valve somewhere when I get to it. Kind regards Rusty_iron Brisbane, Oz. Quote Link to comment Share on other sites More sharing options...
Archie Zietman Posted December 28, 2007 Author Share Posted December 28, 2007 pikkies of the forge at work. Yesterday (the picture day) I almost-finished some fancy candle sticks, and I knocked out a drive hook and a little s-hook for my room both in 5 minutes. Uses a little more than a gallon in 3 hours, on full blast, which is really efficient. Overall, its beautiful though loud (hearing protection earmuffs). I get yellow heats really quickly (less than a minute for up to 1/2 inch square stock) and can work up to 4 pieces at a time. Also, the heat is always constant and I don't have to worry about hollow fires, it's a very predictable and easy to use forge. woohoo! (also, I finished my college applications, so can now forge on saturdays) Merry being, Archie Quote Link to comment Share on other sites More sharing options...
acoop101 Posted February 25, 2008 Share Posted February 25, 2008 I was using waste motor oil when I caused my iron crucible to melt but it works really well for brass and aluminum with old fryer oil. Quote Link to comment Share on other sites More sharing options...
Frostfly Posted February 25, 2008 Share Posted February 25, 2008 I think I'd be REALLY nervous using motor oil. All sorts of fun stuff go in to those. Used cooking oil will prolly keep your lungs in better shape. Bacteria is a bad weekend, Heavy metals are forever. Quote Link to comment Share on other sites More sharing options...
