I've been researching the web and all of the forums and I've had a small hiccup with my first foundry build. I built a box of dirt foundry and ended up burning through the bottom of it and caught it on fire a little bit. I plan on modifying it but I picked up a 20 lbs propane tank today that has a valve issue and I got to thinking. Does anyone have experience with pouring plaster of Paris and play sand mix over kaowool for use in a charcoal foundry I'm only going to be melting mostly aluminum, brass, copper and possibly try my hand at making some bronze or aluminum bronze in the future once I -
Melted steel in 4 Minutes. How annoying!
glumpy posted a topic in Induction Heating, Oil forges, etc
I have been playing with a WVO fueled Burner in a pile of bricks as a furnace. Had a bit of a disaster when I went to melt some aluminium and burned through the steel crucible in about 4 minutes. -
Hello fellow metal workers, I have some questions regarding making aluminum tank tracks for a robotics project. The tank tracks are 4.25" wide x 5/8" tall (length TBD) they are made up similar to the way an Abrams tank track is put together. I found a metal works company who specializes in turning small 6061 aluminum - rubber coated wheels and though expensive they can produce what I'm looking for. So now I'm back to the tank tread portion which I'll probably make myself. My experience: 10+years experience with TIG welding/fabrication and can weld most things. Many years ago I read a book -

Hi Guys, Been looking into casting some of my own parts as 1 off part purchasing is bloody expensive and no where near as fun. so I have been doing some research on casting, forging, furnaces and so on. I have put together a bit of an improvised plan for a 44 gallon drum, as i want something that can handle some decent size casts as well as have the capacity to go up to irons and steels when i get experience with the craft. As i wouldn't mind doing a bit of smithing as well. From all the designs I have seen, they all require the basic drainage in the bottom, a hole in the side for

Here is the start(midway)building of a Heat Treating / Burnout Oven(for lost wax casting wax burnouts) I'm building. 14" x 14" x 17-1/2" tall inside. This will have 4 heating elements. Grooves made with a standard wood router and a template. The temp will be controlled by a PID digital controller w/ ramping step option. More pictures to come.

Howdy! I'm planing on making a forge where I can melt iron, charcoal, sand, and glass to make carbon steel! I am very fascinated by Wayne Coe's Inswool Kast-o-lite Plistix/ITC-100 Propane forge in a 20 gallon tank. I would absolutely love to go along those lines for my propane forge, but I want to get everything (if I can) locally at a Home Depot/Lowes or something. But I need do need my forge to reach temperatures of almost 3000 degrees Fahrenheit. There aren't any refractory supplies near my location and if I can i would rather not buy online. Thank you!

Bit of iron bloomery goodness. -
Bloom straight out of the furnace. Tried to compact while too cold. Broke into pieces, some furnace bottom and slag still attached. Forced to stop at climatic moment to deal with wife's chicken customers who showed up unannounced, driving my dog insane. Hit it while too cold. Sigh......Well, got some good pieces to reheat and refine. -
Bloom immediately after pulling out of furnace. Too cold! Some of my wife's customers showed up unannounced, dog going nuts, forced to deal with them. -
Furnace was damaged by thermal shock of cold rain on hot clay. Eventually started coming apart. Had to patch quite a few times. Gave up on recycling slag after awhile because tuyere was getting blocked and I didn't think the furnace would last. -
view down the "spyglass" into the tuyere. -
furnace after first charge -
Well, chicken emergency is over, supposed to rain tommorow, and gotta work in the morning, so firing what I've got to harden a little against the rain. Loaded up with charcoal remnants and stuck a blow dryer to where it would force air in the slag hole. Nice effect. Probably should have built a fire around the outside too, but not gonna have the opportunity to watch it and make sure nothing relights from the ashes. Such is life. Finish tommorow or the next day, weather depending then ready to smelt! -
well, tuyere's in, got the first 20 inches up, minor chicken emergency, finish it later. Gonna be about 14 inches i.d. at bottom by about 30 inches tall. 12 inches i.d. at top. Walls about 3 inches thick. Tuyere is black pipe at 10 inches high, pointed about 20 degrees-ish. Built around a box wire frame. -
log stuck in for slag hole -
Bloomery attempt number 1, the muck and a very puzzled four year old. Daddy, didn't I just get into trouble for exactly the same thing? About 2 parts red georgia earth (a lot of clay, but a little sandier here than some spots) to 1 part fireclay, and a nice helping of pine wood chips to honeycomb it a bit once fired. -
Base for my first bloomery attempt -
Me at the Etowah day use area in N. Georgia. All that remains of the biggest iron working area in the south prior to 1900. All under a lake now, except for this blast furnace, which is around 60-70 ft. tall and could in its heyday run around 9 tons of pig iron a day. Same area I go to get my hematite. -
I'm interested in getting started in casting, and I intend to do primarily investment / lost wax casting, for things like blade fittings/pommels, scabbard fittings, buckles, and really anything else I feel like casting. Online sources are good, but what I'm looking for are recommendations on books for learning what I need to know to get started in lost wax casting. I intend to build a waste oil furnace like this one: http://www.artfulbodgermetalcasting.com/2.html for melting the metal. Dan Manders recommended a book for lost wax, but it seems to be a little hard to find. I also found thi

In a couple of weeks time, I will be traveling a considerable distance to take a look into a used continuous furnace we are looking into buying. The furnace we are looking into is a Can-Eng Continuous Belt line. It is gas fired. Max temp is 960 C . The line consists of a cold loading entrance, hardening furnace, belt quench, post belt washer/temper. It will be re-bricked prior to shipment. This will be the first time we buy used machinery, What should we look at when visiting the furnace? and tips on what to pay special attention to? What documentation should we ask the seller to provide
