Good concept. The holder with paper shim is not tight enough to stop micro vibrations when cutting. The purpose of the holder is to hold very firm. The depth of cut will be greatly effected. If you design the handle to apply both forward and downward force (to clamp the cutter) would help.
Thanks! I did a bit of measuring the other day, the repeatability appears to be well within 10 microns. I imagine it's at least as accurate as when I use the cross slide to retract/advance the tool.
The repeatability on that isn’t going to be any good. It’s a notable effort, but without an accurate “return to zero” the repeatability wont be there and your threads will likely always be out of tolerance. Plus every one of them I’ve ever seen or used always retracted on their own through either tool pressure, mechanical “switch”, or a shoulder. A good example of a complicated but homemade version can be found on the “Shed Dweller” RUclips channel.
Why won't the cam return to zero? There's going to be some slop, but it should always max out in the same place. I would have liked it to be integrated with the tool holder for rigidity, but the repeatability should be ok.
I think the cam does lock in the same place, the lever rests on the top cover when engaged. I'm interested though, so I'll measure the repeatability. It's probably fine for the level I work at - have always creeped up and test fitted when cutting threads. I've been thinking about using a solenoid for auto retract, sounds like a future project 👍
I did a bit of measuring this morning, the repeatability appears to be well within 10 microns. I imagine it's at least as accurate as when I use the cross slide to retract/advance the tool.
I see it, and I understand it, but.... why? I mean, I get pulling the threading tool off the workpiece, but you still have to stop the carriage to keep from crashing the tool holder into the chuck. Or am I missing something? Nice work, though.
Good question! I've used it a fair bit since I built it, there are a few benefits: It's quicker than using the cross slide, You can't lose track of the cross slide, It's easier to use the cross slide to advance the cut (I usually don't have the compound installed). I'd also seen much more complicated versions of this tool before and wanted to build this simple version. There is also the idea of adding some kind of stop so that the tool is automatically retracted, so you just have to disengage the half nut. It's then safer to cut the thread at a higher speed.
I have seen a cut off tool with something like that. It’s basically like a tap follower. So when you go to use the cut off tool it will push back if it gets too much pressure. Keeps from breaking the tool or destroying the part. Nice job. 👍….
Here is a link to a automatic thread stop that I made for my lathe. It would probably work pretty good in conjunction with this tool so you could then automatically stop the carriage and then pull out the threading tool. ruclips.net/video/AOKd6anp3lQ/видео.html
Very nice!! Reminds me of the retractable threading tool from "The Shed Dweller"! 👍
For some strange reason, I really like the fact that you left in the sneeze.
Remember it making me laugh when I was editing, so left it in there!
@@PaulsGarageProjectsby the way, Gesundheit!
i finally saw enough details so this makes sense. Thank you.
Brilliant idea, simple and elegant.
Thank you! Cheers!
Who knew someone would use the rotary table as a display table...lol. nice work too.
Thanks! I'm too stingy to fork out for a proper lazy suzan!
Actually a ToT trick from a few years back. :)
A great idea!. It beats turning dials. 👍
Thanks! It's great until you instinctively wind out the cross slide unnecessarily!
@@PaulsGarageProjects Human nature! 😂
Awesome Idea, I‘m definitely going to make one myself. Thanks for the inspiration!
Thanks! It's a fun little project 👍
Muy buena idea y de lo más práctica para el roscado. Gracias por el video.
That's a very good idea. Something to keep in mind.
Thanks! I didn't have the original idea (it's probably older than me), but did come up with the simple way of making it 👍
Extremely sweet idea!
Thanks for sharing
Cheers
Thank you very much!
Skvělá práce, a hodně zdraví do další skvěle práce a nápadů 👍🇨🇿👍
Love it!!.... just what I'm looking for, I'll be making a similar one.
Thanks! I've used it a few times since I made it and it works great!

Thanks for the tips!
1:38 bless you!
Super patent. teraz dodałbym jeszcze jakiś automatyczny odrzutnik cofający nóż w miejscu zakończenia gwintu.
I like it 👍 Great idea !
Thanks! 👍
This is a great idea
Well done, nice editing, stop biting your nails.
Many thanks! Like to keep them short - more of a nail clipper than a biter!
@@PaulsGarageProjects Good man.
Like that! 👍 🇬🇧
Thanks! 👍
Nice work. Careful though: You don’t want ypur tool drawn into your workpiece.
Good point!
NICE Job .. Good idea 👌🏻
Thank you! Cheers!
Good job 👍👍
Thank you! Cheers!
Does it chatter more than normal?
I've used it a fair bit since I made it and haven't had any trouble with chatter. Although I do run the lathe at a slow speed when cutting threads.
Clever! 😊
Thanks!
Great idea but not sure how accurate it will be to get continued depth of cut
Thanks! I did a bit of measuring the other day, the repeatability appears to be well within 10 microns. I imagine it's at least as accurate as when I use the cross slide to retract/advance the tool.
Paul very nice work. Do you or where can I find plans? Thanks

Make one for internal please

Des gfoid Mia ganz guad.respekt oida
Do you have drawings for this, I would like to make one.
Hi there, you can find plans here: paulsgarageprojects.blogspot.com/2023/12/retractable-threading-tool.html
Muchas gracias por el aporte
I like it..
Thanks!
As I'm a numpty - would you consider making one to sell?
Hi Mark, afraid I've got too much on with other projects and stuff to make another one.
Mmmmm .... Nice!
Thanks!
Merci
Good
Seriously?..... i cut threads one shot. Not need to do 5 passes on a .100 thread cut.
We got a badass over here. Look out for captain stretchhfab with his infinite torque lathe lol 👍
