Create Custom Nut?

mail8YLTP — Wed, 17 Aug 2022 08:32:43 GMT

I have created a custom thread but I need to create a nut on it. I figure I use the 'Section Analysis' the same way as a normal nut but what is the process to cut my existing thread into the nut?

Hi,

Try this way.
If necessary, an offset (negative))of the thread flanks must be added for smooth operation.

Problem has changed... I couldn't get the correct profile in my first version. I had put put a fillet on my profile sketech, so this thread is correct but it won't let me offset the faces to get my clearances for 3dPrinting. I am totally stumped at the moment.

Oops I seem to have replied to myself. This should have been directed to you. On the first example I used your solution and it worked fine. But the thread profile was incorrect so I had to modify it. I don't know if it is because i added fillets to my profile sketch but now it won't let me do an offest greater than 0.02mm which is not enough clearance for my 3dPrinting. I am stumped...

I would start over using the technique shown in this video starting at 18:41: https://www.youtube.com/watch?v=nwsPWjqPz6M

Crumbs I spent hours on this problem. Watched so many videos with all similar techniques but none of them worked with my profile. I had already watched the video you suggested but gave up because the section where he sketches the profile still didn't work with mine. Haha, if I had watched a few seconds more he said something like "but this is not the way to do it"... then he went on to use the chamfer tool. I don't know why he bothered to put the section in when he had no intention of using it, Anyway the chamfer method works perfect and in fact is the easiest of them all. So thanks for sending me back there. I suspect you went through the same half dozen cups of coffee watching it as me. 🙂 I do like this guy though, although he is a stickler for detail he often gets the bits others miss.
