Hey Fellas!

I have been wanting to start forging at my own house for a while now and it's finally starting to happen. I'm just about finished with the forge and here are some of the "in progress pictures"

Here's the forge body. Some people seem to have trouble with finding good sized pipe but if you go look at the scrap yards it really shouldn't be to hard. This one is about 8 1/2" diameter I welded a rebar handle to it and I'm about to cut a hole for the burner port. The "X" is the location of the burner port, The location is fairly important but I just do it by eye. what I do is eyeball center then take a little bit more towards the opening.


My Lincolin 225 Arc welder wasn't quiet up to cutting this complettly on it's own so I drill a series of holes around the perimeter and then cut it from there. This might not be the best way but it was the best I could reasonably do and that's what I did


Fitting the burner port, it took a bit of fitting to get it in there but I got it where I like. I also angle the burner port "slightly" towards the back and try to make it so the burner flame will be curling around the chamber.


The pipe walls are often to thin to properly tap IMHO so I and going to be welding these 1/2" square stock on there and tap into those.


I taped the 1/2" square stock and then welded them on and here we are( these welds are not all that great but they are WAY stronger than necessary, I'll keep working on the welding but these will last a good long time I should think)


Fitting the K-Wool(It might be Inse blanket or somthing like that...some brand)


Finished fitting it:


I still need to add a coating to the blanket(I'm using satinite) but I decided to stop there and finish this knife, then work on the burner

I'm going to be building a venturi burner for this forge. I considered buying a T-Rex burner and almost did then decided it wasn't worth it so am building it. I have built and used blown and venturi burners but I like venturi for general forging how I like to do it. Blown might be better for forge welding but I'm not going to be doing much of that and will probably make a separate forge for that.

Venturi Burner Accelerator:

This isn't really a tutorial or and explanation or why it works it's mostly just a picture documentary. Michael Porter's book is a really good resource if you want to know more about these
 
This is what we are going for


These are most of the parts, for a 1/2" venturi burner I'm using the .023" MIG tips I believe.   


Using SCH 80 1/8" pipe I drill it out with a #3 Drill for the 1/4-28" tap


Keep that tap strait!




Here it is all taped...nice and strait!


You probably don't HAVE to shape the out side of this but It can help with air flow...and makes it look cooler. You should probably at least grind or the threads on the one end


Not perfect but still pretty good, a metal lathe would be handy. Make sure to not grind around the MIG hole.


Now we need a bushing that will fit of the 1/8" pipe and keep it centered in the 1/2" pipe. I did that by using a 3/8"x3/4" bushing from the hardware store and turning the outside down on the belt grinder with one end in a hand drill till it fit


This is basically what you want


That's all I have for now, I'll post some more pictures later.

Okay, Here is the satinite added to the forge:

I find that a fairly thin mixture is best for applying satellite and I like using a cheap paint brush; Also, Spraying down the wool with water helps applying it.



And here it is all applied; Rather ugly but it works



I haven't shown the finished burner part of the build but here it all is on it's first run(I just turned it one, it would take longer to warm up)



How cool is that?


The burner took some tweaking but got it running really smooth. I will probably be adding doors and a steel rest this weekend.

I also meant to mention that I get most of my forge supplies from www.HighTempTools.com(Regulators, Wool, Hoses, Satinite etc...)

Look'n good
knife too.

when i lined my forge i took a length of pipe that was approx as long as the forge and rolled it over the Kaowool after the wool was inserted . It leveled it out the wool pretty well ready to be coated afterwards.

Also sprayed the kaowool with water before i spread the Satanite - one time i tried to spread satanite onto some other project and it was significantly more difficult to control the work.

Love my forge -

Mine's about 19 inches deep -

looks great D!!

once you build the first one, youll have to make room for more. I have 3 in the shop, plus the foundry, and am thinking about building a 4th :}

while you are building this one, think about ways to make it as versatile as you can. my medium forge which is the one I use the most has doors on each end, that you can open and close, and sliding doors built into the doors so I have a lot of adjustability in how I want to run it. also I have an extension forge that you can butt up against the back of the medium forge, insert its own burner if you need it, and it almost triples the lenth. and I just came up with a sliding workpiece holder for the forges that is built into the rails that they sit on, that you can extend to whatever lenth you need to hold the end of your work where you want it in the forge, which sure beats a separate stand, or sitting there holding it forever when you don't want to.

Thanks John! Yes! spraying the K-wool with water helps allot. In the first forge I made I mixed the satinite WAY to thick and it was hell to spread(and I didn't use water) but a couple forges latter and I'm a pro(sort of Wink )

I don't think I can hardly find any more room Joe! I sure wouldn't mind more though. I really wish I had more room around here...space has just become more and more at a premium as I add tools to the shop. I guess I'll just have to go buy barn...I wish...someday I'll have more room... 

I'm definitely going to add some doors and a built in stand but that might be a week or two latter. I probably won't add any sort of extension though, I doubt that I will need to heat anything longer than 12" all at once. I might build a blown burner option for this forge.

I really liking it so far, I may have to go to the scrap yard this weekend to get some stuff to the door and a few other things. I added satellite monday and fired up the forge(after letting it dry) and that burner is running like a champ!

Thanks Ed! I appreciate hearing that!

I went to the scrap yard this weekend to look for a few things for the forge but didn't really find what I was looking for, but I did find some goodies for a new grinder. I decided I had enough to at least add a steel rest. Like an idiot I forgot to pick up some steel to make a door for it though(Head slap!) alwell I'll get something for that later.

here it is, still need a door:


I also got to work on a new design:


A friend was over and we were drilling some rather exotic materials:




Thanks for taking the time to look this over guys! I appreciate it!
