Been kicking the idea of building a take down in my mind for a while, and eyeing your work has sent me over the edge.

I am not positive I will make it a take down, I may peen the pin over a brass bolster, BUT thats besides the point. Only a slight change between the two.

I was planning on cutting the slot into the end of the tang, and welding a threaded rod onto the end, for the tang nut to screw onto and bring the blade/handle/guard together.

Is there any flaw in my idea? Comment would be much appreciated, and I hope you dont mind me "borrowing" your system.

Here's my prototype, after a few hours of drawing out blueprints, and even more working on it with a file. I still need to even up my riccaso/tang area a bit more.

Should I taper the tang more? Or leave it as is?

Thanks!

I think your idea sounds great.
Steel is pretty tough, so you can minimize your tang considerably and have no fears.
Take-down knives are certainly NOT my idea.
There are deffinitely a couple things that I have "invented" in the five years I've been doing them, but I was taught by a fellow who has been doing them for 20 years.
I have an early 1950s Swiss bayonet that is a take-down, with threaded tang and all, just like mine.
I think they did it for manufacturing purposes.
If you weld on a threaded stub, just keep in mind that it needs to me narrower than your ricasso area where you slot your guard.
I'm sure you've figured that out by now.

Thanks Mr. Anderson.

Kid, that looks very cool!  Keep us posted.

IN GOD WE TRUST

Well, I have my guard filed and fitted, my pin welded, and the blade as cleaned up as I am going to get it before re-tempering.

I decided on a hidden tang with a peened over pin holding it together.

Heres where I am at now...

 

Blade is looking great Kid.

You're making a lot of progress.  I think you're about to mess around and get the hang of this stuff.

Oh, and just to clarify the terms.  I think what you're talking about doing is know as a through tang.  If the tang passes trough the handle and is attached to a hilt, butt plate or pommel by peening, bolting or pinning...it's technically a through tang.  Hidden tangs don't come out of the handle.  

What your doing is actually something that sword makers have been doing for a looooong time.  So it will be good and strong for sure in a knife.  

Great work!
