I welded my nuts

Apparently I need to teach myself CAD, also. I'll get there, one of these days.

I don't have CAD either. You could make a simple line drawing and upload it to something like Potobucket and then post it. I've done that in the past.

After an attempt at visualizing what you are attempting to do (as well as looking at the pic in the linked thread), I have developed a headache.

Glad I'm not the only one who got to the end and the only response that came to mind was "A better pic would've been much more effective than the last thousand words" - but I didn't post it.

Pops, we want to help you, but you need to throw us a bone here bud.

Could you broach the square hole you're after? I'm also wondering why it needs to be square? If I'm getting this right, you're trying to do some kind of cutting along the face or OD of the object being run through these nuts. There's really nothing preventing you from attaching some other apparatus to the exterior of your threaded collar, and that would save you a lot of trouble in the process.

[armedandsafe]

Maybe this will help. The left nut has a guide plate recessed into it, flush with the face. The right nut has a groove milled into it, 0.050" deep, 0.750" wide. A cut plate has been recessed into it flush with the bottom of the groove. The center is the guide/cut unit assembled, with the insertion opening/hole showing on the left side.

These have not been cleaned/polished/blued and the guide/cut holes have not yet been mating reamed.



I finally realized that I had posted this over in the General thread, but not here.

Oh, there is a "slot" betwixt the nuts, not a "hole"! I think I get it.

Calling it a slot makes many people suggest I use a solid piece and a slotting saw. If you look carefully at the left side of the assempled piece, you will notice that there is an opening. That opening goes all the way through the assembled piece, completely surround by metal. That is a hole.

Nanosemantics aside, Pops, a quick sketch would have lifted the veil of confusion for myself and possibly some others.
The pic of the 2 nuts apart says much more than the assembled pair.

I agree. We had such a spirited discussion over in General, I completely forgot that I had not posted that picture here. My apologies, gentlemen.

Pops, don't fret. I got what you meant the first time. May come from working in job shop where we have to figure out what the people want even when they don't know or can not actually discribe it clearly.

Question-what keeps the plate in the grooved nut from rising up against the other plate after assemble? Looks like you are making some kind of noozle or jet? Soldering the assembly would wick into and keep the plates in place where as welding could possibly leave the plates "float".

I was originally soldering the washers into the recess and then soldered the two nuts together. Now, I notch the nuts about 1/16" on two sides and spot weld them to the nut. I then grind off the lump and notch the two nuts in two places. That pair of notches are where I weld the two nuts together. Those two lumps are then ground off and will be covered with a small piece of brass with identification information etched into them.

I'll have a set of pictures later showing the entire proces of building this progressive die later this Summer. It is designed to cut discs of metal, which are then shaped into a cup. One stroke cuts and shapes the end product.
