Built a forge last night.

I decided that I wanted to get into making knives two weeks ago. My wife and I were in Leavenworth WA for our 26th anniversary and I saw a small custom knife shop on the side of the road. We went in and looked around. Come to find out the guy teaches classes on how to make custom knives. My wife said I should do it. Understand that I have a huge collection of knives that my dad started me out on back in the 60's when he shipped me a box of Filippino knives. Most of my knives are working knives...not your fancy "put on a shelf" type. Anyway....I came home and told my son-in-law what I wanted to do. His face lit up with a smile from ear-to-ear and says that he has always wanted to have a forge since shop in high school.

I get home last night from work and Justin is out in the shop. He has two boxes of fire brick and a roofing torch. So we talk about designs and come up with one that we liked. My shop has a fireplace in the corner so that sounded like the perfect place to set the forge so the heat and fumes will ventilate out the chimney. We are going to add a hood on the front edge of the fireplace to pull the heat and fumes into the opening. The forge is 23" long and the fireplace is 23" long so the heat and fumes go into the room and not up the chimney.

Please click on the link below and visit the pictures I took and posted in my Yahoo Photo Album. Please give me all of your comments on what you like and anything you think we should change. I had a piece of 1/2" round stock sitting in the corner. We stuck it in and it was red hot in about 2 1/2 to 3 minutes.

We are making a few adjustments today like angling the handle to the right by 45° so it is not in the way and the flames don't lick up your hand when you make an adjustment. We also are going to try and use a fan and pipe the air into the torch for more air flow. We had to make some adjustments last night because the flame blew itself out.

I loaded all of the pictures in order but for some reason Yahoo. mixed them all up. I added comments to them so you can at least know what you are looking at.

Sorry about those of you who have tried to look at the pictures and couldn't get in. I forgot to open the access to the album. That is corrected now so go take a look and let me know your opinions. My wife told me that Justin is out looking for a forge today....we are heading in the right direction.

Looks like that might work! Maybe down the road you could add/rig up another burner or two, with the idea to eliminate or reduce any cold spots you may encounter. Good luck with it! -Matt-
 
Justin made some modifications to the gas input. He used a high velocity fan I had, taped some dryer vent to it, and attached it to some 3" pipe. He drilled and taped a hole in the side of the pipe and inserted the gas wand (he removed the torch head). Now we are getting a good force air input which takes less gas to heat a blade. Problem is my 5 gallon propane bottle won't keep up with the flame. We can forge okay when it is full but the flame cuts out once the tank gets down about half way. Any suggestions on how to prevent this? We are thinking of getting a larger tank but the expense to fill it right now is a factor. Propane was running $2.25 last week.

Justin also shortened the length of the forge up by a brick length after I took these pictures.

Please let me know what you think of the mods and the forge overall.

i was having this problem with my forge and what i did to solve it was i got a big tub it was one of those plastic storage containers that have the 2 pece folding blue lids. any way i filled it with water and put the tank in the water. this keeps the liquid propane at a temp that is high enought to keep the gass flowing full force. i could run a tank bone dry this way and never see a decrese in gass pressuer tell it was all gone. try it and see
 
Click on the link in my first post again and scroll all the way down to the last two rows of pictures to see the latest. The guy in the green flame retardant shirt is my son-in-law for Oklahoma. He is a HUGE train fan. We gave him a R/R spike to pound on.

Thanks for looking.

Not as much as we did with version 5 (I think). Justin (my son-in-law who built the forge, the tall one in the pictures) had that one breathing so hard you couldn't walk in front of it. He has toned this one down so it isn't as bad. I'm going to put another fan in the front like some have pointing straight up to force the heat up. He hasn't had a chance to use it yet so it will be interesting to see how it does. He is already talking about cutting a hole in the back. He also needs to redo the refractory cement on the inside. It was cold when he put it in and he didn't let it set-up all the way before he fired it up. All the cement cracked and fell of the roof of the forge. I doubt he will fix it. H doesn't have the patience to wait.....
