Title: Threading a Tang and Take Down Hardware
Post by: gables on October 14, 2010, 10:30:00 AM

I understand that I can round the end of the tang with a hammer, but how do you get the tang the perfect roundness and proper dimension for cutting threads?

Are most of the nuts for take downs custom made?

I do not round with a hammer. I grind the tang square first to the dimension of the thread you desire.
Then grind those corners off to make it octagonal.
Then carefully take that to round.
Each and every step of the way repeatedly checking with a dial caliper so as to not go too far.

I make all of my hardware with mill and lathe.
The end product you desire dictates method.

See if you can find a chart of drill and tap sizes. I usually try to use sizes that are most common so I can find nuts and bolts of those sizes.

Soemtimes I just round it the best I can, leaving the area to be threaded slightly large and work the die down on it. If it cuts without too much force, it will be fine, but dont force it too much or you'll break something. Make sure the tang is soft before you try to thread it. Lin

Edited: I was typing while Karl was. Karl is telling you right. Sometime the "shadetree" in me comes out.

You can cut the tang a bit short and weld on a piece of redi bolt or all thread, just add a nut that matches the thread pattern.  Not quite as pretty when pulled apart but it does the trick.

Thanks for the info, it got me headed in the right direction. I don’t yet have a welder.  I found threaded screw post online. I will get 2" long posts, grind the head off and end up with a threaded tube. Then I'll thread the end of my tang, screw on and jb weld the threaded tube to the end of the tang. Next, I'll countersink the buttcap and or butt of handle and hold it all together with a countersunk stainless screw.
