Your drilling skills are superb. 0:44 I used a milling machine to drill holes one day just to be lazy, but all the holes were misaligned, and the offset and direction were inconsistent. After many tests I found out that my feed rate was incorrect and that there was still a chance to correct the bit before the taper angle was fully in the surface of the object.
OMG I am so making one of these. Thank you for showing how you did it. Great work even while improvising when needed. Congrats on the new tools. New tools are always so exciting. 😀 I ❤new tools. (and old tools, LOL)
Agree about the cutter mount grub screw, potential weak point if screw overtightened, however, a beautifully finished and very useful machine tool. Both the tool and the video presentation are a credit to the presenter.

Wow that works great ! With the addition of some sort of indexing fixture on the lathe spindle you could use this tool to cut the lines on dials as well .
Brilliant job, if I was to make one I'd silver solder a cap threaded to clamp slotting tool. And turn bar around 180 degrees so I could see when Ive got to starting depth then dial in to complete depth.
Hi and thank you very much for your comment! You have some good ideas. The clamping thing I didn't get I guess. How would you do it? Turning the tool by 180 degrees is a really good idea. Thanks :)
@@WeCanDoThatBetter , where you have your clamping screw for cutting tool. Silver solder on a some round bar same size of tool bar with a tapped hole for clamping screw (grub screw). What you have will spread (deform) slot.
Great build and fun to watch. Been a machinist for over 25 years and have done this numerous times. Can be very tiring on the lathe for sure. Only thing I would recommend if anything would be slowing your reamers down quite a bit. Would give a lot better finish and last a lot longer. I know your machine aren't the type with lots of bottom end torque, but about 50% of drill speed is rule of thumb. Anyhow, great tool and great videos. Thanks for sharing!
Such a great idea, it beats my way by using a chuck in the tail stock and using a boring bar with cutter and sliding the tail stock back and forth, I have started to make a cam style key cutting tool that works with via an electric drill that mounts on to the tool post. Maybe an idea for a future project.
Thanks for your comment! Yes, a kind of motorized attachment would be great but I think more complicated and probably much bigger, so I decided to go the "analog" way first :)
Great video, I like how you make every part with accuracy. It would help a little if you put a gear motor with speed regulator instead of a handle. Thanks for sharing
I'd say that works really well! My only concern with one sided cutting tools on a lathe, especially a small one (similarly with the push style knurling wheels) is the high side load on spindle bearings. I was also unsure on the grub screw, I'm pretty sure a smaller grub on the side of the shank should hold well enough if you can find a way to register the tool on the rear of your slot, shouldn't be difficult with a tapered tool. Why does technical speak always sound so smutty!
Yes, this is a weak point. Perhaps I make a new clamping in the future without slotting the entire thing and making just a pocket for the cutting tool so that the grub screw has proper support. Thanks for the hint and comment!
Bravo. Wie immer eine perfekte Arbeit. Super wenn man die Werkzeuge selbst machen kann, nach eigenen Angaben. Mann kann ja manches bestellen, nur das muss man alles verbessern. Zur Zeit ist es so, egal was kommt, das kommt aus China und das musst du immer nachbessern. Manchmal sogar Kleinteile ersetzen. So versuche ich auch vieles selbst zu machen. Du hast super Ideen. Ich freue mich jedes Mal auf neue Videos von dir. Wenn ich ein paar Fragen habe, meinst du das vielleicht beantworten kannst? Ich meine falls du Zeit hast. Okay, ich wünsche dir alles gute und bleib gesund. Dennis.
Your new Proxxon mill is fantastic, these are quite expensive in Australia, you are very lucky to have it given to you 👍. One thing I have noticed is that your lathe and mill are not bolted down to anything sturdy? They seem to move around a bit? If they are bolted to a strong , heavy bench , the machine surfaces will be better 👍

wahnsinn , wunderschöne Arbeit was du da mit den maschinen lieferst! das ist grenzwertige spitzenklasse! viele würden sagen ohne top maschinen ist so etwas nicht möglich ! darf ich fragen was du machst ( beruflich , wo ist dein background )
Vielen Dank für dein Lob! Das freut mich, wenn meine Arbeit gefällt. Beruflich komme ich nicht aus der Ecke. Habe aber schon etliches an Erfahrung in diesem Bereich in unterschiedlichen Stationen sammeln können.
Sehr schöne Arbeit. Bei dem Werkzeugaufnahmekopf hätte ich persönlich aber Bedenken. Ich hätte eine Tauchfräsung gemacht und die Verrundung vierkantig gefeilt, zumindest die Seite gegen die die Stossnadel läuft. Für mehr Stabilität in dem Kopf. Ansonsten Top.
Danke Dir. Ja, das wäre tatsächlich die bessere Vorgehensweise gewesen. Danke für die Anregung. So weit hab ich nicht gedacht :) Werde bei Zeiten einen neuen Halter machen. Dass man die Ecken ja auch mit der Feile rechtwinklig machen kann, hab ich irgendwie nicht auf dem Schirm gehabt :)
Nice work at the keyway tool, but the grub screw to hold the cutting insert look like a weak a point. Drill a hole and use pin mill to make slot in the cutting tool holder to insert the cutting tool and the grub screw has the whole around to hold the cutting tool firmly secured without expanding the cutting tool holder.
Hi and thanks for your comment! Yes, that is definitely the weak spot. For other keyway cutters I have to make a few more holders in the future. I will try to make them different so that the grub screw can not bend the part.
@@WeCanDoThatBetter You can use HSS round solid shaft instead HSS square or rectangel bar and drill hole to example 5 mm hole for 5 mm HSS round solid shaft instead make slotted hole and screw firmly with grub screw. Select the diameter as you desire and grind to the desired width adapted for the keyway. It take less work to make new tool with hole instead slotted hole. There are many diameters to choose from in both millimeters and inches when buying HSS round solid shaft.
The job you made is good one, I enjoyed the making of this video both parts.. But It could be more far better if some jobs had been done by highteck cnc machine.... As the Ellen screw on the top to fix the tool is the weakest part, I hate weak parts while tooling... The slotting done, If I've done that job i had did it in my style, I like the strongest made items, It's my way of thinking.... Grab Love from Agra India Suneel Kanda
Thank you! I machined the bore in the position the tool is mounted later for operation. Thus it is automatically on centerheigth if mounted with a 2mm shim as during machining.
Very impressive to see a button insert cutting smoothly in a mini lathe. Can I ask what brand of taps you use ? They seem to cut very well is all materials & produce great results.
For keyways in shafts you most probably need a milling machine or kind of. This tool needs a free entrance and outlet for the chips of the tool. This is given when cutting keyways in holes such as pulleys, gears etc.
@@WeCanDoThatBetter Is it possible that you could cut a keyway only on the part of the shaft needed by first using the parting tool to put a groove before and after the target keyway location? Just a thought for something to try so that a milling machine can be eliminated from this process.
I don't understand why the oil groove for the brass bushing is on the outside and not the inside, that oil filling port means you will be using a paste lubricant, right? Does the lubricant run off easily?
Hi and thanks for your comment. I will use oil for lubrication not grease. There are oilpumps for the fitting I used here. I didn't make it that clear in the video: The oilgroove is on the outside of the brass bushing so that the oil filled in can flow on the outside of the bushing around and enter on two points through little holes into the bushing and lubricate the plunger. I made these two holes off camera. But oilgrooves inside the bushings were also good, I will add them.
Why bore backwards, with the work on the tool post and the tool on the spindle?? I imagine there’s a reason I’d never seen that technique on a lathe before.
Hi. That bore in the brass bushing had to be very accurate. With the cutting tool spinning in the lathes spindle I ensured, that the bore has the exact same diameter throughout the whole length and is parallel to the aluminium body and also on exact centerheight when I later use the keyway cutting tool. If I had done it the traditional way with boring bar in the toolpost and part in the lathe chuck, the bore might have turned out slightly conical and less accurate cause small misalignments in the lathes ways or spindlestock will get relevant. Hope, that is somehow understandable:)
Ottimo lavoro ma, ritengo che la vite di tenuta del tagliente, non sia sufficientemente fissa; non so se con lavori sull'acciaio possa rimanere stabile.
You would be much better off using DIN7991 inbus screws rather than DIN912 ones for the toolpostclampingthingypart (or a handle as you have very well put it in English).
I don't have a native Deutsche Sprache either, as you could have already noticed in my accent. Thus, we're even! But that doesn't stop me from making fun at germanwordmakingapproach - so neither you should hesitate to speak English. Just get it check with a dictionary - or better yet, vocabulary - more often than not.
Broaches are very expensive and you need a set for every size you have to make. This tool is much more versatile as you can easily made new cutting bits in the desired size.

Probably still more sturdy than the actual Chinese lathe. Lol. Hopefully your endeavours pay off and all the best for the future

Yes, this is a weak point. Perhaps I make a new clamping in the future without slotting the entire thing and making just a pocket for the cutting tool so that the grub screw has proper support. Thanks for the hint and comment!
