forge blower

admin

i decided by next winter i want a shed with a forge and some blacksmith stuff so i can crank up some coal and stay warm..i found a handcranked champion 400  blower , a blacksmiths vise which needs a spring and mount and a large stake which  along with my piece of rr track is gonna see some anvil duty..been watching videos , fixin to build a forge..i took out my old digital air monitor to see how the blower worked..turning real slow and easy, maybe 10 rpm on the handle, i get around 1100 fpm at the 3" round outlet, so 54 cfm..thats going into a  firebox smaller than a shoebox..i think 50 cfm is  enough by codes to exhaust a toilet..  cranking it harder a getting a deep wooshing sound showed 2400 fpm, so 118 cfm...mine has no brass oil cup on top of the casting  like some i see fotos of, but there is a hole to put in some oil..it turned absolutely beautiful  even before i put any oil in it..the gears are brass and look to be in  real good condition..

Reply:That is awesome!  I would also like to have a forge complete some time this spring/summer.  I plan on using one old front hub/rotors from my cargo van for the firebox.  I live out in the country, but have neighbors close by.  Hopefully nobody will mind hearing me beating on metal for a few hours a week.
Reply:some progress to show..made harder by the fact that i dont have forge / blacksmithing  experience ..i did some internet research, and learned what i could but at some point you gotta build something..i used 4" wide (roughly, i torch cut it, made for some interesting fitup issues.. ) 1/2" thick strips cut from some 4 x 4 x 1/2 angle i have for the firebox. it is about 12 x 12 at the top and 6 x 6 at the bottom.  tuyere (sounds like a french toilet but its the name for the traditionally cast part where the air enters the firebox) 4" sch 80 pipe , 3" sch 40 at a 30 deg angle for the air inlet, 3/8 plate for the cleanout and 3/4 for the handle. ilike how the handle turned out, as you lift it to open the door it contacts the wall of the pipe, you can give it a good hard rap and knock stuff loose. second-to-last .last foto is upside down still have to add hearth and legs, and a little more to the handle so it stays shut..but thats the easy part.

Reply:Looking good. I keep debating how I want to do my coal forge. I like your idea. It's one of the nicer ones I've seen yet. Looking forward to the rest of the project..No government ever voluntarily reduces itself in size. Government programs, once launched, never disappear.

Reply:Looks good. Have you thought about making the the grate removable? It will burn through and need replacement now and again. How large of a hearth are you planning?
Reply:forhire..i found one guy on the net  who used 1/2" and said it had lasted him for years. but as you say, when it burns through, it has become removable, and i'll put a new piece in place..thinking about 30" x 30"  for the hearth..probably some more 1/2" ...got plenny of that 4 x 4 x 1/2 angle..dsw..thanks..next post will have hot coals..
Reply:my forge is  operational..since last post i added a hearth , legs, and a counterweight for the cleanout named the forge monster..my grandson says he wants to paint it blue.. Attached Images
Reply:Looks good... especially the recycled Lincoln tin. How many bricks broke using your anvil on the brick pile?
Reply:I have one of those "Pole Vises" at the shop.....zap!I am not completely insane..Some parts are missing Professional Driver on a closed course....Do not attempt.Just because I'm a  dumbass don't mean that you can be too.So DON'T try any of this **** l do at home.

Reply:Looking good! At this time I think any suggestion is not going to be of any good but if you happen to modify the forge... may want to make it a tad more rectangular instead of square... Will be easier to bring a long blade evenly to temp before quenching (for heat treating).Good job!Mikel
