Self Locking Lathe Tool Height Adjustment

[hersch_tool]

Hi all,
Here's a quick and easy project where I made some "self locking" height adjustment knobs for my lathe's quick change tool holder.
Thanks!

Nice and impeccable workmanship. Permissible is what likes.
But I would be annoyed by the nut's dead angle the allen key requires.
Why not (e.g.) slit a larger ø nut laterally and clamp/brace it with an axial allen screw?
We know this principle from 'playless' spindle nuts.

That's certainly not a bad idea!
My initial design definitely has some weaknesses, I'll likely make a V2.0 at some point in the future where I'll address the locking screw issue and any other issues that I come across while using it.
Thanks!

You sure were patient repeatedly answering that same point in the YT comments. It's a good demonstration of Cunningham's Law though.

Haha, I've never heard of that before, but it's 100% accurate.
My wife said something similar, "I guess you can use YouTube as a way to check for flaws in your tool designs!" lol
Always looking for the bright side.
And yeah, I figure folks don't read other comments very often.
And I'm just grateful that they watched my video and took the time to post a comment, so it doesn't bother me so much when I look at it that way.
Cheers!

Just remember. Good engineers pay to have their designs checked and evaluated. Great engineers get it done for free!

I to am frustrated by the current jam nut version. Seems to fiddly. So I hope to make a few of these for my most commonly used holder and see how it goes. Bet it goes much better than what is currently used. Basically, it's the answer to my problem. Thanks.

You are very welcome!
Thank YOU for taking the time to watch my vid, and good luck with the project.

Hi Hersch, Thanks for sharing your tool height adjuster.
With your tool height set precisely, how do you lock the adjusting ring if position of hex lock screw is hidden by tool-post lock handle?
Or do you set the height to the closest 1/2 turn?

Lol, check some of the other comments, this question has been covered A LOT...
short version is, you can slide a washer underneath to re-clock the screw, or just lift the tool holder off the tool post to tighten it.
cheers!
