Threading 3/32" Diameter rods
When I cut 4/40 threads on my 3/32" rods, the thread is not as pronounced as a machine screw in comparison. I mean to say the peaks and valleys are not as big, meaning that a nut would slip off more easily.
I checked the diameter of my rods with a micrometer and they are good. The only odd thing is I can turn the die with my hands which says to me that not enough materials is being taken off.
Any thoughts?

I've made several 3/32" stainless rods with a 4-40 thread, using a standard die, and never have a problem with the nylon nuts slippng off. If that concerns you, buy new nylon nuts aand screw them onto the rod letting the rod be the "tap". That's what I do.

Threading 3/32 rods
If you are comparing the threads that you cut on your rods, To store bolts or rods in your steel. They may be Rolled threads. As the thread is rolled half the thread is cut down into the rod and half the thread is raised up by the pressure of the Die plates. to get a full thread you will have to go to 3-48 thread like Ross suggested. Good Luck and Happy Steelin.

Most of the time, the nylon tuners you buy are not threaded. I just checked with Mouser, and they don't have nylon hex spacers/standoffs in 3/48 thread. Just use the threaded rod as a tap for the tuner.

It was a big deal on my GFI. Mine was built March 10, 1995, it is an all pull, S-10, and was originally a 3p, 4l. I added I've added one lever and several pedals over the years but I am back to 4 Pedals and 5 levers. It was while trying these modifications that I began having trouble with the nuts stripping. I was using 3/32, 304 welding rod to make my pull rods. For what it is worth GFI uses a rolled thread which increases the diameter of rod being threaded. Thus you have a smaller rod/ lighter guitar, with the same advantage as a 7/64 rod. I believe that is correct but if not please clarify. As my late buddy Doug Seymour used to say, Gene Fields was a mechanical genius.

I have a lathe so it wasn't too hard to make my own. If I remember correctly, I did have a bit of trouble finding 3/16 hex stock. I eventually got connected to US plastic through Don Burrows. Here is the link I located this morning:
https://www.usplastic.com/catalog/item. ... emid=22963 .
Of course if you don't have access to a lathe you are probably better off looking for the proper nuts already made.

Threading 3/32" Diameter rods
I have always used a UNC 4-40 die for 3/32" SS rod. That includes re-rodding an Emmoms LeGrand SKH, LeGrande II, and about 1/2 a Carter D-10 with no problems. Check the adjusting screw so it is not spreading the die.

Re: Threading 3/32
Me too. And I am about to rebuild my Carter D10 undercarriage using the barrels in place of dogbones. I will make new rods for each change.jay thompson wrote:I have always used a UNC 4-40 die for 3/32" SS rod.

Threading 3/32 rods
Hi Jay,
I would like to thread some 3/32 rods. I am concerned about how to get the die started straight. I saw your old post and was wondering where you got the knurled die stock. It looks like this would work better than the one with handles. Thanks for any advice...Bill

Grind a bevel on the end of the rod you are about to thread.
Then fix it firmly in a vise with out too much protrusion or you may bend the end of the rod. I use my nylon jaw Panavise; to get a good non slip grip I fold a strip of fine emery cloth over the rod. This won't mar the rod much if at all.
Start with the correct side of the die; you'll see a conical "entry" ground away from the threads inside the die.
Use RapidTap or equivalent cutting fluid. Keep it wet.
Don't worry if the die is slightly cocked as it starts, it will straighten itself out when it is fully engaged in the cut.
Cut a full turn, then back off a half turn, and repeat until the thread is as long as you need.
It is pretty easy with the right stuff and a little practice.

FWIW, Franklin uses 1/8" aluminum rods. He uses a 6-40 die to cut threads on the 1/8" rod.

Hi Larry, There is a website named DU-BRO, https://www.dubro.com/collections/allLarry Hobson wrote:Ian,. Which hobby stores ?
That has rods of various diameters and lengths. You might try them. Hope this helps.

Threading 3/32 rods
Chris,
Thanks for the threading tips. I was concerned about the threads not being straight. Sounds like it's not a big problem.
