Update: "Nut" with 2 parallel sides instead of threads

[dukes909]

I am looking for a "nut", for lack of a better term, that has 2 flat parallel sides in it instead of coiled threads. See silver nut in attached picture. The nut will fit over a metal rod that has a matching flattened area on 2 sides. The outside of the nut can be a regular 6 sided type that will fit in a handwheel or dial that I can fabricate out of plywood. Does this thing have a name that I don't know that would make it easy to search for? If not, any ideas on how to fabricate such a thing?

Picture of assorted parts of from a completed sale from an auction site back in January - no other parts are currently available for this tool (saw). Other pictures show close up of where nut needs to go on rod.
Cheers!

Do you have a pair of calipers?

What’s the flat to flat distance on the outside of the nut? (The wrench size)

Whats the ID, from round to round and the distance from flat to flat on the inside?

I wonder if I need special diameter mill cutter to make one.

13mm wrench fits the flats. I would have thought this would have been standard as it is made in USA but 1/2" doesn't fit. Looks like 15mm OD of round bit.

Believe that's a double d collar you are looking for. Might be able to modify heavy truck shock socket?

Or slide a sleeve over a 6pt socket with 4 sides cut out.

Thanks I'll look around for the double d collar thingee. Not clear on the 6 pt socket part.

Safe search buddy!
Look in the end of a 6pt socket next to your part... If it still doesn't make sense I can get a pic of one.



Lol I **** at web draw on phone

I sort of understand but what is the sleeve part?

 

[Ole Slewfoot]

Whatever you do to keep it from falling off to the side....maybe pipe drilled to size or mild steel formed around the socket.

There’s got to hundreds of those Delta RAS’s that have been pulled apart over the years. You check fleabay for the part?

I have. The picture of the assorted parts is from a sale there in January. Nothing currently.

I'd just find an open end wrench that fits and keep it on top of the arm on a magnet til one comes along. I think I reset the arm angle on mine maybe a dozen times in 10 years.

Did a 5 year old make that drawing?

I'll be the first to criticize you for your remark, surely not the last. Not even a laughing emoji? What practical use was your comment to the GJ member who offered a constructive comment to the O.P.'s dilemma?

Next time, use some KY to make things easier on the penetration.

I agree w/cvairwerks, just keep a small adjustable wrench there to reset it when you need it and keep an eye out for ebay.

Probably a custom part, who knows. If the width across flats (wrench size) is 13mm, the round part on the inside of the same nut can’t be 15mm I wouldn’t think. I wonder if the shaft OD is different where that nut goes on.

The reason I am asking is I have a milling machine. I can put a nut that is 13mm across flats in the vise, plunge in the hole with an end mill and then move the table left and right to create the rounds on each side of the inside of the nut. Not sure if it will work, because where the flats meet the round on the inside is a sharp corner, if I mill it, that transition will not be a sharp corner. But you could probably take a file and finish that transition until it fit on the shaft.

I don't doubt for a minute you know more about milling etc than I ever will but a 13mm fits the flats exactly and a 15mm fits the round exactly; I even had a friend with digital calipers come over and check it.

In any case, I did not want to wait potentially forever for a part to show up on eeebay so I made a dial out of plywood and carved out the nut shape with a chisel in the center. Then I mixed up some high strength JB Weld and coated both the outside of the d-shape part of rod and tge interior of the hole I chiseled out. Compressed it onto the rod and let it set up for 24 hours. Turns the rod just fine now and I even made a plate to cover the roller track opening that was never there before. From a distance it looks ok but at least I don't have to worry about the front being open anymore and I can turn the rod for miter cuts now without a wonky locking plier hanging off of it, .

I don’t know that much about milling either, but I can jury rig some stuff!

I think I understand better - I meant width across the flats meaning the outside of the nut. As in if I was going to put a wrench on that nut to turn it on the outside, like to remove it from a bolt, what wrench size would I get. I think you mean the inside from flat to flat is 13mm wide - in that case, sure the round part on the ID could be 15mm. I was thinking the inside round can’t be 15mm, if the flat to flat on the outside is 13mm.

As long as you got it working, that’s all that matters.
