Another beautiful build it’s nice to just relax and watch something be put together from raw materials just something about this is relaxing thank you for the opportunity to watch this awesome little build looking forward to the next one
Nothing like a craftman creating his own tools by combining a series of different crafts in a higher level! I got ispired once again by your videos! thanks!
Conceptually a great idea, well thought out , executed & a professional looking finished product. However, there are two areas of concern that I feel could be improved. The main concern is that all the longitudinal travel loads are being taken by the small stepper motor bearings. It appears to be a Nema 17 with integrated lead screw. Although these stepper motors with integrated lead screw are designed to take end load, they are not designed for the type of forces being exerted on them by your system. The second area of concern is the 'ball guide' system used for the alignment of the piston assembly very quickly wearing with alignment issues for the slotting cutter.
could 1. be resolved with the addition of a thrust bearing to handle the axial loads, or would the rigid coupling between the leadscrew and stepper still result in too much axial loads being transmitted to the stepper? (I'm not an engineer... yet.) for 2. , I'd like to know what a suitable solution would be. The first thing that comes to my mind is a linear guide rail, but I'm assuming there's another solution of a smaller footprint.
@@seleniumshutter 1: "(I'm not an engineer... yet.)" Keep thinking like that & you soon will be. The 2 most important question you can ask are Why? & How? Question everything ! The stepper motor needs to be totally isolated from the longitudinal load via a flexible coupling & thrust bearing used on the separate (isolated) lead screw to take the considerable forces applied to drive the cutter into the piece being machined. However, this would also mean a considerable increase in the size of drive section which also defeats one of the desirable criteria of the project (compact size). 2: There is a big difference between good engineering & over engineering. Using a linear guide rail would alleviate the issue but at a considerable increase in the size & cost of producing the project with minimal gain. The basic principle used for the guide pin is sound, however, the execution could be improved. The ball only contacts at 1 'concentrated point'. Using a simple square ended guide pin (brass / bronze) in place of the ball would would spread the concentrated wear area exerted by the ball resulting in a much longer life before maintenance is required. With the current design the ball is also the harder of the 2 materials which means the shaft will suffer all the wear. Standard engineering practice when designing for wear is that you make the easiest part to replace the sacrificial piece (softest material). Which is easier? To manufacture a new guide shaft or to manufacture a small brass/bronze round key. Purchase a small brass solid bar of appropriate size, cut a short length off, done. Actually you might even spend another 30 seconds while you are making one & cut yourself a lifetime supply of spares :)
Awesome build! I think this is the most compact toolpost 'power tool' I've seen. Btw, I think you should be able to get rid of the whine from the motor by configuring the motor driver to use microstepping.
FYI this is called keyway broaching. Slotting is something different. They make broaches for this kind of thing that you can use with a simple press and are much quicker. While I applaud your design, it is neat, it's got many problems which others have alluded to and would struggle with hard materials like steel and take forever. I'm assuming this was aluminum in the example.
These machines are usually called slotting machines or slotting attachments, they are also sometimes called broaching machines but if you were looking to purchase something for your lathe or mill then "slotting" would be the keyword to search with. The two phrases broaching and slotting are mostly interchangeable but there is some nuance: Slotting is the application, whereas as broaching is the act of pushing a broach through or against a workpiece. A broach is customarily a multi-tooth cutting tool, or single-tooth for a rotary broach, because the tool cuts to its full depth in a single pass, whereas slotting is an incremental machining operation. They are not fully distinct and separate operations with no conceptual overlap, after all a shaper machine is not normally called a broaching machine even when being used to cut a slot. For my money I'd argue that Maker B named their beautiful project work correctly, it's a great complimentary tool to go with the nice precision Sherline lathe :)
The broaching is done with a long tool with a large number of teeth, where each tooth is larger than the previous one, and this is meant as one operation.
@@henkormel5610 When you freeze the brass it results in a slightly lower diameter. Much easier to press into the outer sleeve. As it returns to ambient temperature the friction fit becomes stronger. Other option is to heat the outer sleeve for the same effect, but utilizing the growth due to temperature change. Disadvantage of this is - now you have to handle a hot part These are both common techniques for press fits
Нужен ещё один двигатель - на поперечную подачу. И синхронизация нужна. А то сейчас возможна ситуация, когда ход резца не окончен а вы подкручиваете подачу. Так и резец сломать можно!
Everything was great and beyond amazing, but I didn't get it. (maybe because of my ignorance) Why did you need a device like that? Is there no way to create a notch, to inner side of a solid circle? Really I didn't get it.
Très bon travail belle exécution mais franchement pourquoi perdre son temps à faire un outil que la fraiseuse remplalace très bien ???? Une explication m'apporterait certainement une raison mais là DSL je ne vois pas !!!
Did I miss the part where an alignment jig of some kind is used to get the square part set correctly on the end of the round tube. Or, is this just machinist voodoo going on here?
Your clips are so beautiful that one can't help but want to watch them over and over again.
Glad to hear that, Thank you very much!

Exactly. The OP is incorrect.

Broaches are expensive and in my experience prone to failure.
와...매번 신기하지만 이건 생각지도 못했네요..대단합니다!!!
hey bro conguratulation,its really amazing
Basically a really small shaper, nice 👍
Sure is!🙏
Nicely done.
Very good job and perfectly planned,end result is fine. Thanks for sharing.
Much appreciated, thank you!
Great work. We shared this video on our homemade tool forum last week 😎
Amazing Craftsmanship 👍🏻👍🏽👍🇬🇧🇬🇧
Perfect work. More video brother
Nicely done and entertaining to watch
Please make such more videos...love from india❤
Next time freeze the brass tube.
For shrinkage or rigidity? Elaborate please?
@@Tsskevik shrinkage
Or warm up steel tube
It is a press fitting and not a shrink fitting. What are you talking about?

14:05 The first time my wife seemed interested in watching a lathe video with me... 😂😉
Very nice work sir
Very nicely done! ,Subscribed!
Awesome, thank you!
that's so cool!
Bravo très bon travail
1:10 You better not shout, you better not cry, you better hold on as I'm going in dry.
Nice Job..from a Machinist.
Thanks 👍
Great job! Does it work with steel too? Respect. / Прекрасная работа! Со сталью тоже работает? Респект.

At 4:25, how did you square the top piece to the milled face?
Hi, very nice work! Is a pleasure watching you video. You will make available the Arduino code?
Я примерно об этом и подумал, когда смотреть начал😊
No tengo ni idea para qué sirve eso, pero es muy guay 😂
Nice job.
Thanks!
dude what kind of mill and lathe do you own? any brand recommended? keep rocking man.
Все хорошо и исполнение отличное а как насчёт стали? Алюминий очень мягкий материал, надо попробовать сталь!
It's nice.
wow! Is it capable to slot a steel?

brother can you please put some generator or put that IC engine to some good use, I want to see it loaded up and doing work please
Amazing work! Can I ask you to send me the code for the arduino? Thanks
what kind of a drill press are you using ? model # if possible please ?
I personally love to have it 😅 great feelings ❤
Cool idea maybe try grinding a hss cutter and run it in a cutting cycle rather then file setup
The whole time I thought you where making a slot machine
😅
What lathe do you have, please?
I think it is a sherline
I would gladly pay for plans for this!
Everything was great and beyond amazing, but I didn't get it. (maybe because of my ignorance)

Brand of Small Manual Lathe?
simplified method is use pneumatic cylinder instead of stepper motor
What mini lathe is that?
what lathe is this?
Sherline

Nice idea and execution. But that motor sound... please change the driver. Put a digital driver.
That's what a keyway cutting broach is for...
They are faster, and cheaper, and more reliable 😂
Très bon travail belle exécution mais franchement pourquoi perdre son temps à faire un outil que la fraiseuse remplalace très bien ???? Une explication m'apporterait certainement une raison mais là DSL je ne vois pas !!!
👍👍👍👍👍👍
You could made it powering with USB.
hes using an external driver, which take more than 5v 2A, of which more would be needed anyway under these loads
👍
Women would love this if you make it faster
Did I miss the part where an alignment jig of some kind is used to get the square part set correctly on the end of the round tube. Or, is this just machinist voodoo going on here?
I thought the same 😅 But alignment is not critical for this part. You can place it basically in any angel you prefer.
