How To Make A MINI FORGE For Knife Making. Testing to see if it actually works.

How to make a mini forge for knife making. In this video I show how to make a cheap heat treating forge, and see whether you can realistically heat treat a knife using it. You could probably forge a small knife using this mini forge but mainly its for heat treating after stock removal. This is a great way to get started with knife making. You can absolutely heat treat a knife using a mini forge like this one, if you pay attention to a couple details.

Same, just recently found (and subbed to) this channel within the last month or so. I’ve never considered myself an expert on blades and sharpening them but I’m not a rookie either. There’s a lot of good knowledge to be had here and he keeps it interesting for pretty much anyone wanting/willing to learn. I appreciate that he works with products that are readily available and usually reasonably priced. Too many channels out there working with unlimited budgets (thanks to sponsors) and showing off their “unobtainium”. I’m more interested in the “regular guy’s perspective.

[@mikafoxx2717]

​@@MrIgottapEven worse is when they have unlimited budget and give awful advice still, quenching water quench steel in canola oil or something.

[@lacanian_lifter]

I can say for certain that this method works exactly as shown, because, after watching your intro knife-making guide, I heat treated a knife pretty much exactly the same way. That said, I did use heated canola oil, as I think another KZbinr had perhaps advised. I ran into no problems in the course of making two knives which have been in regular use in my kitchen for about a year. Thank you again for this very helpful recap.

[@samuraidriver4x4]

O1 can also be done using this method. After a couple of knives I quickly build myself a heat treating oven and that works alot easier with actually temperature control.

[@joepublic573]

this has to be one of THE BEST intro's to budget / beginner heat treat techniques out there. absolutely brilliant.

[@daw162]

I have a tip, and I use a forge to heat treat. It's worth getting a known annealed (not coarse spheroidized) sample and getting it just nonmagnetic with no further temperature change, and then quenching the steel and snapping it. Then, buying or if already on hand, using a hand held microscope (of the $17 variety off of ebay) to take pictures of the sample. then until the following is doable, test methods using offcuts of various alloys and save the pictures with titles (this is probably useful with a furnace, too) * confirm that the samples done to the same eye/color control as a knife don't have coarser grain than the original low-processed low heat sample * work on thermal cycling to be able to bring a coarsened sample back past the point to where the scope picture of the snapped sample is better than the original low-temp fine structure if using something very high in carbon, like 26c3, buy a nicholson file or a good vintage file and snap it. the iron carbides will make it look slightly more coarse. These kinds of experiments take about an hour tucked in some day when you're not, including the documentation (the small samples in a small forge take only minutes, even with thermal cycling). I have never bought a furnace because I don't make anything but chisels professionally, and I can match and in some cases better book toughness at same hardness with excess carbon steels (I use 26c3 most of the time). But it probably took a few combined hours of experimenting over a period of a month or two to learn what refines and grows grain, and how much different some steels are vs. others (for example, 1084 grain growth is almost instant - 26c3 is much less quick to grow grain, as is 80crv2, but it takes experimenting to find out how far past nonmagnetic by eye - and how long). The reason I use a small forge for chisels and small knives (I have three forges, including one that's a typical large two burner stainless type that will output more BTUs than two gas grills on high) instead of buying a furnace is chisels get hardened only to the bolster (no reason to heat them past there) and fully hardened only about 80% of the way up there - and because the thermal cycling needed to bring back grain size for 26c3 takes only a couple of minutes with a chisel - all of it, including the final heat to quench, vs. waiting a long time for a furnace. That and my tested samples/coupons from the forge are tougher at typical hardness (64) than any of the furnace samples the metallurgist had on file. they were subpar before this perhaps unromantic array of testing and comparing samples. Pictures are needed to really get down to brass tacks because once you can better something like a commercial file, it's not always easy to just eyeball something and tell if it's better than another past effort. All of this costs almost nothing - the hand scope that I use was $12 - the cigar shaped ones that are everywhere.

[@GibsonCutlery]

Great video, as always! A trick for making sure you have reached the curie point (and where in the blade that is happening) is watching for recalescence/decalescence. When HTing in 2 brick forges, another thing that can help is making it a pass-through design and building an "alcove" in front the mouth of the forge out of some additional fire bricks. It gives enough space for your tongs, but helps hold the heat in there so you can pump the blade in and out through the hot spot to draw the temperature more evenly. This requires having a sidearm burner or something like that - you can't quite pull it off with a plumbing torch.

[@toazeno]

My tip for this would be that you can get the fire bricks from a pottery supply store (which might be local) a lot cheaper than Amazon.

[@chasebartell8805]

I’ve used this same mini forge technique in the past with great results. I had a 2 inch wide chamber with a good MAPP torch and quench in Parks 50. As long as you get get an even heat you should have a good hard blade! Great video brother 😎🤘🏻

[@mountainbearoutdoors]

[@VeritasNous]

I made a lot of knives in almost exactly this way using a single brick. I made a larger hole (probably 1.75 inches) and wrapped the whole brick in thin steel wire to hold it together so the cracks weren't a big deal (you can use copper, or whatever). The angle and location of the entry point for the torch makes a big difference. I made mine so that the entry point was near the back, angled down and towards the front. Then the flame swirls down the center of the brick towards the front and heats it up more quickly and evenly (. I was heat treating 1/4 stock knives. It took about 3-4 minutes to get the 1/4 stock up to the right temperature but it totally works with a bigger hole and thicker stock. If you pay very close attention to the way the blade is heating up, you can even get a great "dirty hamon" with this setup.

[@jons2447]

Thank for the excellent content! This is the way to go, My first attempt at heat treatment was done in a fire pit shaped like a hopper. I drilled holes in a piece of 3/4” pipe which I coved with hardwood charcoal. The pipe was hooked up to a shop vac to provide air. In no time I melted a carefully hand made knife blank made out of 1095. I was shocked how hot that forge got. It was so disappointing. This is the way to go,

[@poncho151]

I have made several knives using 1095 high carbon steel, I wonder if this setup would work. It sure would beat my charcoal chimney with lump charcoal and a hair dryer heat treating that I have been using. My system works, I have made some knives and torture tested them and they have held up, but I would prefer an easier way to heat treat. Thanks for sharing.

[@jackkuehneman9300]

An even cheaper and beginner friendly method is just making a plaster and sand combo forge. Soft bricks are expensive and this way can give you a few uses to see if you like the hobby or if you're just making a knife for yourself

[@OUTDOORS55]

Soft bricks are $28 for 2. Thats hard to beat even with plaster and sand. Not to mention the time saving involved. I would definitely recommend soft firebrick over plaster diy. It's easier, less messy, way less time consuming, and will heat up better and hold in the heat. Just my opinion though from trying both methods.🙂

[@felixdzerjinsky5244]

I have actually made small 5" utility knives in a one brick forge, so, yes heat treating in one of these is perfectly feasible.

[@8thsinner]

I like this, makes me think it's within my reach, and I know you can hamon treat 84 but I would like to know what you would recommend to clay and water quench something like a spicy white steel, it's pretty cheap to buy and has good reviews as a steel too, only the hamon of course makes it potentially nicer looking. It takes a higher hardness than 84 too so I am thinking for smaller knives it's edge is going to last longer. You reckon this kind of forge could do that? If not, what modifications would you make?

[@-I-Use-Punctuation]

You can always heat your water to help avoid edge cracking during quenching. This set up, down to the magnet is all straight out of Wayne Goddard's book, the $50 knife shop. Awesome book

[@martkbanjoboy8853]

I wonder if an air acetylene torch would be more forgiving - except I'd have concerns about damaging the torch nozzle. Maybe the propane torch is the better option for starting out.

[@neko8715]

I would love to see you do other steels on this setup. can it handle the trendy steels right now? cpm154, Nitro-v, 14c28n? it would also be cool to see you heat treat something that is maybe too advanced for the setup and see how it fairs against higher end steels. Awesome video as always!

No forge will handle those steels. You need exact temperature control in a kiln for them.

Wouldnt it be somewhat of a good thing to have a softer tip? So it just bends instead of breaking? Just curious. Thanks for these videos. I'm really wanting to make some knives.

[@FuKuNPVT]

i always wanted to try making this but this also makes me wonder a few thing can you answer or try them out in a video. like you messed up the heat treatment a bit at the tip and end of the first knife is that not salvageable? you made a video you can over temper for too long, but like with the first knife can you try again, such as heating the whole thing back up again and try to quench it again. and if you temper it down from to 60 and try heat Treat to whole thing again and quench. and or maybe try heating Treat just the tip and back parts only and quench. oh and maybe a video about different quench oil like you sway to worm it up but how much is warm really? if different oil would need to be more hot than parks 50 and what about water warm it up or room temp or cooled and such. nice video gl in next videos

[@hanelyp1]

With a forge that tight around the blade, would it help if the forge was a bit wider right at the torch inlet to allow the flame to circulate around to both sides of the blade?

[@phil2082]

Dr. Larrin Thomas has a section about heat treating oils on his website. Apparently, standard vegetable oil - canola oil - doesnt work well on 1084 steel. Apparently, it works great with O-1 steel, though. Any experience with O-1? Im going to make my first forge tomorrow and don't have Parks 50 yet.

[@OUTDOORS55]

I have a video doing similar tests with canola and other types of oil and canola did work well for me with 1084. Cant tell you why or how though. Which should highlight why its probably not the best idea to use an unknown oil since different people get different results. Id just pick up some parks 50 that way you know for sure.

[@phil2082]

@@OUTDOORS55 Dr. Thomas showed that canola oil does partially harden 1084, but it never fully quenches to a completely hardened blade, so you never get the full benefit. O-1 steel doesn't have the same issue. But he uses an electronically controlled oven to heat his blades first, which I don't have.

About the small chamber - nah, the space is basically irrelevant. Even if it would be 2L in volume that would heat up in seconds. The problem is the surface - cause that is where the heat gets lost. And the bigger the volume the bigger the surface that has to be heated up and that takes away the heat.

Why not just edge quench?

[@OUTDOORS55]

There no real benefits to edge quenching anymore unless you are doing a hamone.

@@OUTDOORS55 Im curious, whats a good place to learn up on that. Not that i dont believe you, i am just really lookin into making knives one day.

[@OUTDOORS55]

Check the description. I left a link for a book by Dr larrin Thomas called Knife engineering. Its a very easy read with lots of pictures and graphs for us folks who like that sorta thing😉 It will explain everything you ever want to know. It's definitely worth the money.

@@OUTDOORS55 Awesome, thanks!

3:12 Definitely not good for the torch, especially if you have a brass tip 😶 I have a small ball of brass for inlays or something now.. 🤦🤣

The cheapest way is a small pile of charcoal on my grill

[@OUTDOORS55]

You can do it on a grill or fire pit with forced air. I have a video where I do that as well. Its an even cruder set up though and no way to really see what's happening to the steel in the fire.

[@SHIEET817]

@@OUTDOORS55 just got to have an air channel to force a natural draft. Just lay my knives across the charcoal with minimum effort.

i was watching this and had a brain flash and don't know if anyone's tried it before: a video where you experiment with heat treating a bad knife (made of the finest chinese-ium?) to make a good or better one. just a weird thought through my tired old brain.
