So I've been working on my first knife (plain steel, so I don't waste carbon steel when I screw up) but I've really having a problem bringing my forge to heat, usually getting orange at the best.

Are there any easy to build (read: no welding) plans for a forge out there, or even a decent propane or coal (even charcoal) forge in the $200 range someone can point me to?

>> No.842747

i use a hole in the ground with stones lining it for charcoal and a steel rim for my coal

How big is the air hole in your forge? If you're burning too hot too fast you won't be able to get the steel to heat evenly so it won't get very hot very quick. If you find yourself adding charcoal often this is probably why. But of course you could be not blowing enough air. It's all about finding that sweet spot.

Hi there!

You seem to have made a bit of a mistake in your post. Luckily, the users of 4chan are always willing to help you clear this problem right up! You appear to have used a tripcode when posting, but your identity has nothing at all to do with the conversation! Whoops! You should always remember to stop using your tripcode when the thread it was used for is gone, unless another one is started! Posting with a tripcode when it isn't necessary is poor form. You should always try to post anonymously, unless your identity is absolutely vital to the post that you're making!

Now, there's no need to thank me - I'm just doing my bait to help you get used to the anonymous image-board culture!

Blacksmithing noob here, I want to start pic related as a summer project. I have the tools (or at least most of them) to help start (shears/jigsaw, hole punch, hammer), my only questions are what type of metal to use, how thick should the metal be(the pdf I'm using doesnt state how thick the metal should be), and the type of rivets that I need for this.

Any help or advice would be well appreciated.

Here's my first knife that I'm making. Keep in mind that I have no access to an anvil and can only use an old sledgehammer head. I'm a complete novice and would like some advice on how to get a good angle for the blade... I have access to a Tabletop Wheel Grinder, Angler Cutter/Grinder, and a Tabletop Belt Sander. Any advice would be much appreciated.

Looks good for a first knife. The belt sander is your best bet for an even flat grind. just start with some coarse grit sandpaper and work your way to some super fine 450 or 500 grit sandpaper. In the future, add some sort of a shoulder after the blade so you wont slip and cut your fingers. its bad form to get cut on your own part...

You can make your own anvil from a foot of old railroad track. It's not the best but it works alright.

Anon in previous thread mentioned how cheap and easy railroad rails are to get. Not sure how well they work or hold up, but if they work okay IDC since they're so cheap.

I think I might try to get a hold of one in a month or two when I start on my sword. An actual anvil is like $2 a lb, so fuck that unless the railroad stuff really won't work.

>> No.846620

RR Track's too light for big forgework, but its fine for knives unless you're making huge things.

write to your local rail company and ask if you can buy an offcut. its what I did, they sold me a section weighing about 15 kilos / 30lbs for £5 - the price solely there so they had a record of its sale, so I never need worry about being accused of having stolen it from a railway siding - and they even delivered it to my door.

Rail track is usually 0.4-0.6% carbon steel, good stuff - better than the cheapo cast iron anvils you get in harbour freight or places like that. Yes, it'll never match a Vaughan-Hope anvil, or the likes, but for the small 10-15 kilo range anvils, RR track is perfectly fine. just takes a bit of work to shape from a track to a flat face with flame-cutting and a grinder.

OP here. My firebrick forge cracked yesterday, so I had to pull out the old brake drum forge with a few modifications. I cut a portion out of the side so I could heat longer stock and I worked with the tuyere so it fits better. Time to get some hardwood lump charcoal and get back to work!

wow that's nice.

its a small 60# anvil so i was just going to use 4 pieces of 4x4 but not knowing much about woodworking and being entirely new to smiting i don't know how much abuse those boards will take and if i need heavy strapping, massive 3/4" bolts, or deck screws.

by the looks of that link small wood screws will do, and i definitely want to scorch and stain it now.

I know why Japanese blacksmiths make their apprentices spend the first two years chopping up charcoal. Cause it's a pain in the ass to do it yourself and anybody who sticks with doing that for two years really wants to learn proper Japanese Bladesmithing.

>> No.850874

Looking at some historical pictures and some modern ones, on some of them it looks like either the blade's tang either goes the club part completely, of they "hide" the brass pins by making them part of a pattern. I suppose you could also glue it in using a wooden pin or two, then sanding and finishing it to disguise it as "seamless"

I think the handle's fine, but I think the blade could match its look better. The blade looks like it belongs with a wooden, bone, or leather handle.The color and shine dynamics don't match.

very nice piece anon

> I feel I could have done better.
Next time you forge your point, alternate between turning left and right, instead of rolling it in one direction. That will cause the point to be more straight and that looks much nicer on a curl.

Also, before you twist, straighten the piece as much as you can, and make sure you don't bent while you twist.

You did make a very nice and straight blade, im jelly. i would however take more care when cleaning up, like make sure you sand only in one direction, and clean the base of the blade.

pic is a wand I made a while back, forged the ball too.

The faces are hardened for sure, and the sides are not necessarily so. Also, often, the sides aren't even flat (not that the faces don't have a slight curve to them).
