BUFFER TUBE THREADED RING OR BLOCK

[1biggun]

IM LOOKING FOR A SOURCE OR PERSON TO THREAD A HEAVEY LOCK RING OR BLOCK WITH A HOLE FOR A BUFFER TUPE TO SCREW INTO FOR A AK ADDAPTER ON A GUN IM HELPING A FRIEND BUILD FOR HIS 11 YEAR OLF KID

DOES ANY ONE KNOW WERE I CAN BUY A STEEL SLEAVE THAT IS THREADED TO TAKE A AR BUFFER TUBE?????

OR DOES ANY ONE HERE HAVE THE TAP AN COULD THREAD ME A COUPLE IF I SENT THEM THE BLOCKS OR RINGS??
I NEED SOME THING WITH A LITTLE MORE THREADS THAN A THE LOCKING RING THAT KEEPS THE TUBE IN PLACE.

I WANT TO MAKE A PISTOL TYPE TRUNION THAT HAS THE PROVISION FOR A BUFFER TUBE. ON MY SONS BUILD I JUST USED A LOCK RING BUT IT WAS HARD TO WELD IN PLACE WITH OUT DISTORTING AN ID LIKE A FEW MORE THREADS ALTHOUGH IM SURE THE TUBE WOULD BREAK BEFORE THE TREADS PULLED OUT.
I SEE THOSE TAPS ARE PRICY AN ID LIKELY NEVER USE IT MUCH.

I AM AWARE OF THE ALREADY MADE STOCK ADDAPTERS BUT IMO THERE CHEASY AN THEY MOUNT THE STOCK TO LOW FOR USE WITH A SCOPE. ALSO I MIGHT TRY TO MAKE A FOLDER SET UP. I HAVE ONE OF THOSE INLINE FOLDER ADAPTERS BUT THEY MAKE THE STOCK REALLY LONG WHEN ADDED. IF THEY WERE STEEL i COULD JUST MILL OFF THE MALE THREADED PART AN WELD IT ON.

ANY WAY LOOKING FOR A SOURCE OF EXTRA LONG RETAINING RINGS OR SOME ONE TO TREAD A FEW HOLES. OR A LINE ON A CHEAP TAP.

have the proper thread tap of the buffer tube and OSI jig, you would have to cut the hole to the perfect dimensions, I could cut the threads

my tap is not a cheap one

the only problem I have is you are using steel, I have only used aluminum 0% DSA and 80% Tannery blanks.

so is it a thin peice of steel I can clamp to my jig and tap the threads if so its possible for me to do. I am out of town right now and on the road so if time is not essential

send me a PM to discuss further

1biggun, Can you single point thread it on your lathe?

possably but its a lot of work for me. my lathe is a 1932 south bend 9" so im some what limited but I have all the gears. i have never cut internal threads on it.

yea its going to be steel an id hate to have some one mess up a good tap if things didnt work right.

I have been looking at the ACE pig nose addapters for aboout $20 an may be able to make one of them work. I cant find ay were if there steel or aluminum. I was just hoping some one made a nut or some thing that was thicker. so I clould just weld it to a home made pistol trunion.

im going to have to some research. is that thread only used on the AR 15 an m16 recivers is it special?? I need to get my fastener catologs out an see if there is any thig lese using that thread.

I have not ruled out modifying a buffer tube as well an attaching it some how differant may with a sick screw downt he middle into a bored hole in a pistol trunion or some thing like that.

many many moons ago there was a tutorial on using tannery junk casting lowers for emergency shtf scenerios, the builder did not even thread, he ground down the tube threads and smoothed down the interior of the rear of the recievers to size and JB welded it into place and drilled a hole to pin it in place
not something one would want to do with a FFL store bought receiver
just thowing out old ideas

Ok, let me see if I have a piece of scrap that'll work.

Hello 1biggun,
Get some PVC pipe and practice threading it to the AR stock spec. Your Southbend can do it nicely. Tutorials are on the internet from all the usual suspects. No need for a spendy tap. Threading ID is as vital as threading OD for gunsmiths and machinists. Practice on the cheap plastic tube pieces until you are comfortable with the routine.

I make the FIRST pass on steel at about 0.005 inches deep. All subsequent cuts are only 0.003 inches deep to prevent blowing the tool point off or having a wreck. Use tapping fluid. Yes, it takes a while. You'll find that it becomes a ritual that you stick to. 60º threading inserts are very handy. Also use a threading "fish" gauge to help align things, check V-form shapes etc... They rather resemble an arrow head.

Southbends are nice lathes. I'm currently rebuilding a "new to me" old (1950's vintage) 12x36 Atlas.

Above all... have fun.

YEA I SHOULD LEARN TO USE MY LATHE A LITTLE BETTER. INSIDE THREADS IS ONE THING I HAVE NEVER MESSED WITH. THE TIME TO DO IT IS MY ISSSUE. ID LIKE TO BE ABLE TO THREAD A TRUNION BORE ALSO ON THE LATHE SO IT WOULD BE GOOD PRACTICE.

THE THREAD IS 1-3/16"X X16 ITS A ODD BALL TAP AN THERE DONT SEEM TO BE ANY OFF THE SHELF SPANNER NUTS OR ANY NUT IN THIS THREAD.
