Here are a couple that I should have upto polishing stage by the end of the day.

I have to re-heat treat the one on the right because it developed a warp while I was tempering the spine to a spring blue. Tempering worked great but I heated one side too fast and it took a woop...

Blade length on the right is 5". Not convinced I like the handle shape on either one so I might tweak that as well.

Looking good mate !

Gee, you don't mess around. I like the finger grips on the skinner, really looks like it would have a nice feel to it. :thumbsup:

Didn't quite get to polishing stage. They are in the oven tempering now. I couldn't get all the woop out of the 'bush knife, so i ground it out. It has turned into a full flat grind that is looking more like a cooks knife than anything else. The skinning knife is coming up nice too! That is a lost stock knife. I got some "spring steel" from a local engineering shop. The bloke said it had been on the shelf for 15-20 years! Anyhoo... he doesn't know exactly what steel it is so the heat treatment took a bit of experimenting. I think i have it down ok. I just bought a short length that has made two knives. I might get some more if it stands up to some testing.

Will post some pics later.

Bah!!!!

I only have a combustion stove and the oven is ******....

Put the knives in to temper at what said 220C for 2hrs... Should have come out light straw yellow.... Came out Spring blue, which means it was WAY hotter than 220C!!! Will be too soft for a good edge so I have to go through the whole heat treat again!!!

NOT HAPPY JAN!!!

Bah...hahahaha!!!

Good stuff, Noisy. Make sure you set it at a good height for yourself and give yourself a slack belt option as well as a platen.

Wish i had the welding skills, mechanical know how or the cash you build/buy a proper belt grinder. The way mine is set up it already showing limitations.

Well, bladesmithing season is upon us!

Here are some I've been working on. Trying to get a bunch up to polish stage and then fit handles to them all. I'm also working on a simple design that is easy to knock out for the test knives I promised last season. I'll make 4 in total.

Pics below.

Zombie slayer hardened, differentially tempered and ready to take an edge and test. I think it's a bit heavy and will grind down the bevels more and reproduce the hilt a touch before it is finished but want to test toughness and edge retention first. I think I kneed to make a longer, narrower version for extra zombie chopping reach! :lol:

Just when I thought this time burner was out of my system you have to go and stir the pot again...although my 87 year old father wants a Bowie so it's off to the shed again this week. Think I'll do a studded coffin shaped handle.

Sounds good Noisy, can"t wait to see it.. :thumbsup:

Damn I need to get to work on my belt grinder :) Well as soon as I finish all the other projects I have been slaving away at for the missus :wtf:

BTW.. G, I wouldn't say that the Kitchen knife is "failed" just get creative with the handle and set it up to have the tang exposed on the spine and hidden on the belly ;) would sort the issue and make for a nice interesting looking knife imo...

It will be at least a couple of weeks before I get handles on any, mate. I'm ordering some phenolic resin (heat cured resin) to vacuum impregnate some maple and Blackwood for scales and handle blocks. Got all the gear, just need the resin. It will make the handles tough as nails! I'll do extras and sell some. As you know, I have some pretty speccy timber that would make some A-grade blanks for handles and other pieces.

If you're still keen for the knife when it's done, your name is on it! :thumbsup:

That kitchen knife was just ground too thin across the spine and the tang/blade join got down to about 1mm. Not worth finishing due to questionable strength. I do like the shape though.
I have a number of knife shaped pieces of steel that ended up too thin because I forged them out too far (and unevenly) before going to the grinder and lost too much material correcting warps and wobbles.all part of the learning curve and my forging skills have improved a lot. You don't learn by getting things right; you learn by screwing them up!

Knocked out 'Zombie Slayer #2' in about 1.5 hours last night. Will post some pics later. I think I like it! :lol:

:D I'm keen mate, thanks....

So you ended up getting a vac chamber ? How big is it ? Big enough to do stock blanks ? Just thinking that some beautiful stocks and pistol grips etc...etc.. could be produced from the timber you have... I've also had good reports from blokes using vac bags for such things...

Absolutely agree that the best lessons are learned from the screw ups :thumbsup: One can read a million books, but its not until you get hands on and do the hard yards that you truly develop skills....

Yeah, I got a vac chamber but it isn't huge. I think it should be wide enough for a stock blank but i would have to get a taller chamber to fit a stock. All i would need is a cylinder of the same diameter as all other hardware is easily transferable. I have looked at vac bagging but it is an expensive exercise and a bit more complicated than a simple chamber set up. I will be able to do plenty of knife scales, pistol handles, pen blanks, etc..
Should have the resin to get started by next week! :D

I bought the chamber, pump, etc and then a teacher mate picked up another pump from his school's science lab as they were replacing and discarding the old one. It's actually a better unit than the one i payed for, so i now have two! :lol:

Maybe i should test them both and sell the new one off is the old one works fine because i'm pretty skint right now! :problem:

Sure will!
Just got to pick the right bits for the right knife. I should get a few knives out of each piece. They measure about 240x60mm. Possibly 4 knives per blank on the smaller handles.
