Captive nut

[tel]

Been 'gunna' make one of these for a while now - the completion of Boggy's threading tool gave me the excuse!

Nice work Tel!!!
How about a pick of it apart??

Nice job Tel I have seen these before but I will keep your secret I keep telling myself I need to make one with about a 3/4 nut for a paper weight at work.

 

[Jeremy_BP]

I made one a couple months ago. Still can't stop fiddling with it.

Great work. I saw one of these on that ABC show " the inventors" around 30 years ago but i dont think it won

What's rare about 1/2" x 12 ?

One of the first threads ever invented and far better than that abomination of 1/2" x 13 that many lathes can't even cut.

Very nice work indeed ! :bow:

But I think it should have been in the "Tips and Tricks" ;D ;D

Now come on, how did you do it - pztt just between you and me !

 

[Omnimill]

I've been meaning to make one myself. Can I give the game away? ;D

Bit of a joke there John - somebody posted a question on one of the forums about this 'weird' thread he had found in something or other - I forget the details, it's a while ago now.

If you want to keep your hands busy while sitting at your bench, and you want to try out your new DRO, then have a go at making this.

I thought it was an ellipse drawing "compass" but the pencil appears to be missing from the handle end

???

Have you tried fixing a pencil to the end of the arm of that thing John?
