Question: is it possible to make threads on a pipe? And how would i do such a thing without buying a very expensive die. I am planning to make a filament extruder, but i can really put on a “nozzle without threads. Alternatively I could try and weld a plate on to the pipe. And make a hole into the plate. Which is obviously not preferable

[@wildin13]

@@rikdenbreejen5230 yes you can, theres a variety of pipe threads. They tend to follow with the size of pipe you're using. They are external threads though... If you want internal threads you can possibly use any fine thread that fits.

[@places3604]

Spending 2k for making a 1$ nozzle. Honestly this is the kind of things I like, even when it doesn't make sense to regular minds. Great work!!

[@f.d.6667]

Agree. But a the very moment you need a custom nozzle, say in a odd diameter, a bi-metal configuration or with special material properties, the machine will pay for itself in no time. Even more so, when you can save a piece of existing machinery for which no spare parts are available any more by machining the missing bits in your own shop.

[@nate6386]

Absolutely, but making these one dollar parts are the practice you need to have under your belt for when you need to make those really important and expensive parts.

[@fpbibi]

Knowledge is expensive

[@joshuamckown3145]

Also... y'know... you can make other stuff besides nozzles. Even if you only want to do 3D printed projects, a lathe is still a really useful augmentation to one's tool set. Being able to make custom threaded inserts and other mechanical linkages is perhaps the most obvious advantage. If you can print plastic AND machine metal, you unlock a lot of choices for materials and methods in the design of your projects.

[@eighty-eighth_section]

It's also good for practice 😉

[@garethneal82]

I’m a tool maker. You can get 60deg drills or cutters. I would sharpen a drill bit because I can and it’s cheaper as I have drills laying about. Also, if you are looking for accuracy, heat and callipers are your enemy. Coolant and micrometers are the way to go.

[@ronprozanski4640]

Fully agree with the micrometers.

[@Donnerwamp]

Don't forget gauges!

[@ColonelAngus101]

Alternatively, use regular 90deg drill and make outside taper 90 degrees. Or 80.

[@garethneal82]

ColonelAngus101 I think the 60deg helps molten plastic flow.

[@j.t.m.workshop78]

I agree i would also sharpen a drill bit to 60 degrees, crude but effective.

[@3lapsed]

Stefan, I'm not a "maker" at all. I watch all of your videos for a proper education and also entertainment from your discoveries. If the mini-lathe has other projects that get your interest, I'm here for them. If you need a break and want to get into something else, or back to a 3D printer, I'm here for that too. I am interested in the idea of whether or not the quality of a extrusion nozzle matters. Also I'm curious if you can tighten up your measurements and improve over the E3D designs. Great video and impressive work!

[@sivoltage]

I do like the idea of mini lathes combined with 3D printing. I bought a 80 year old lathe for £250 here in England and I bought that as a tool to improve my 3D prints making custom supports and other odd bits. I'd love to see what else you would do with the lathe in future projects.

It's always best to ream the hole to the final dimension, just make sure you get the correct reaming bit because they do come in over and under sized diameters for different machining operations.

[@MSP_TechLab]

Even in 3d printing having a lathe is a huge advange. For example today I printed round lid which occurred a bit off size. Of course it is possible to fix such issue with help of file but it is not convinient. Furtunately recently I printed lathe chuck which helped a lot, although it is not even close to precision of real one.

[@komitadjie]

This was a darn neat video to watch! I love working on the old manual lathes, they're so darn satisfying to use. Being able to make your own nozzles could let you do all kinds of interesting things, as far as internal and external geometry goes, I say most certainly carry on with it!

[@steveorevo]

Yes definitely. I’ve had such a lathe for years but have been timid about doing a project so small. Would love to see more mini lathe projects.

I've got almost the same lathe, but mine is about fifteen years old. I don't use it very often, but when I do, I'm always very happy I have it. I also built my own box frame 3d printer a few years back. So yes, I would like to see more lathe and 3d printer videos.

[@bymitten1]

To answer your question in regards to grinding a 60 degree angle on a drill bit ... you can definitely do this! The key things to remember though are to make each side of the flute as equal as possible (using a fixture is the best), making sure there isn't a positive angle as a relief (you don't want the tool to rub and create excessive force) and to make the cutting edge have the smoothest finish possible. I've been a CNC machinist for 15 years working on Swiss style lathes. I'm looking forward to any future videos on this topic. 😊

[@ChristophPech]

I bought the exact same Lathe from Paulimot. Since it isn't very rigid light cuts are often needed so I decided to convert it to CNC. It's great because now I can use a parting blade to cut any complex shapes.

[@CNCKitchen]

Any information on how and what you did? I'd be really interested!

[@ChristophPech]

I milled a new cross slide on the cnc mill put a stepper on it. The leadscrew uses a ihsv servo, but it has terrible backlash, I should have changed it with a ballscrew. For a controller I used a pokeys57cnc with mach4 and 2 handwheel encoders so I can use it like a manual lathe. Here is a short video of it in action: kzbin.info/www/bejne/gnOpiaytmplpY5o Also this guy has a not yet done series about the conversion of the mini lathe and he does a much better job than I am: kzbin.info

[@llucjofre]

Yes plz, more lathe videos

[@seeigecannon]

Great work. Quick suggestion: you can run the tiny drill bit during the first setup. If you use it after you do the previous drilling operations then you will already have the spot drill and it will be perfectly concentric with the bores (plus you wont need to worry about runout when flipping the part). You would just need to clean up the hole after using the parting tool. Let me know if the wording on this is not clear.

[@theunholyghoster4293]

I know the tooling is a bit expensive when you get down to to the small sizes but can you look into making a boaring bar for the hole in the nozzle and then with that make a tapered id hole for the nozzle

[@KLP99]

I think this is fantastic! Very well done. You again show your brilliance.

[@SKYWURX]

Yes you're right in saying you can grind a drill to a 60 Degree tip. Once you have the angle you want, grind clearance behind the cutting edge otherwise you end up having to put extreme pressure on the drill and part when you try to use it and it heats up the tip. Finally, make sure the last thing is to use a sharpening stone to just blunt the cutting edges of the drill at 90 deg to the cut. The softness of the Brass tends to deform and pull the drill (like a screw) rather than cutting. It seems a bit backwards, but blunting the drill cutting edges slightly helps to shear the material off rather than deforming it. I've used this trick a lot on Plastics such as Acrylic, Acetal, Polycarbonate as well as on metals like Brass, Bronze, and Copper.

[@ajhartmanaero]

I saw this in the background of your last video and wondered if you ever did a video on it. I just got a mini mill and mini lathe and they have been making appearances on my channel. Super useful tools to have around the shop and have been 3D printing things to organize and upgrade them.

[@FischOderAal]

The spring around the jaw tool is so ingenious! I remember even experienced lathe operators breaking their fingers because they got interrupted and forgot the tool inside the jaw.

[@Mistakeful_Learning]

You could regrind a drill bit to 60 degrees to make the new version of the nozzle. Or, you can use a piece of drill rod/silver steel to machine a 60 degree D-bit, mill the cutting surface in half, harden, and then polish with a stone. Both methods will work, the drill bit would have to be free hand ground where the drill rod can be machined on the lathe. There are several videos and texts on d-bit grinding and it is a good way to make custom profiles in the home shop.

I have a suggestion if you plan to do more in the future. @11:25 you talk about the center bit being 0.5mm and you can't plunge it in too far. If you made the tip of the nozzle longer, you can plunge the center bit in further. Then use your 0.4mm drill bit. The last operation would be to take off the waste 0.5mm part of the nozzle. Thanks for an awesome video!!!

In proper maker fashion, this is the best way to use E1500 to make a E5 part.

[@f.d.6667]

Great video, as usual. Picking Paulimot was a wise decision because their quality standards are indeed higher and they do know their stuff and they did help me with technical issues over the phone more than once. I can see that you are using "universal" inserts - but there are also "sharp" or polished ones for non-ferrous metals that resemble HSS tools. Paulimot will sell you individual ones of those for around €4.00 but if you shop around a bit you might find bargains for around 20 bucks for a box of 10. ... as for your parting tool: there too you might want to look at an insert holder and "sharp" bits. What's convenient about those is that you can find parting inserts with a radius - great for O-ring grooves or when you want to turn soft inner corners that dont act as stress raisers - look for type MRMN-200 inserts to find out more.

[@rpavlik1]

Nice job using the half nut on your lathe as a dolly for the benchy boats... I'm impressed your lathe handled your use of that carbide insert as essentially a form tool instead of a single point cutter, I suspect it's not conventional but it certainly made the right looking result. Nice concentricity too for a 3 jaw! I wonder if it would be easier and flatter in the tip if you left a little extra length until after you drill the little 0.4mm hole, to face off as the last operation.

[@BinManSays87]

I used to make drill bit they were for masonry but we had to grind them onsite as part on the manufacturing process after heat treating so if you don't let it over heat and ruin the heat treating I'd say it's well worth a go with an older bit

[@jurassicpork765]

I'm a new machinist, I've been at it for about a year. The one thing I could say here is that you can get those same inserts in HSS. You don't have to use carbide OR grind your own tools. That being said, if the carbide's working for you, use it. I use it at slower speeds at work because the rounded cutting edges don't chip as easy as steal. I've even got my boss doing it.

[@Rulusto]

As a professional CNC lathe operator, about the grinded drillbit. It is certainly possible to grind a drill bit to that a 60 degree angle, or you could buy one. For best results i would recommend using a cutting liquid as well when drilling in brass.

[@infernaldaedra]

Hey a tip if you are planning on doing cutaways in the future especially if you are trying to retain small features or fragile parts you can encase a them in a hard resin before cutting away.

[@jamesstevens2362]

You’ve done a great job with this Lathe, and it looks like you got a good one to get such accuracy! You’ve got all the good accessories, especially the tool post and digital dial indicators. I bought one of the same models a few years ago and it was complete rubbish! Nothing I could do would get it working properly. A case of inconsistent Chinese quality control. I agree with you about manual control. There is something very satisfying about shaping a piece of metal by hand.

[@smorrow]

Not a machinist, but grinding bits to the right angle is how people used to bore chambers before 3D printing. (Now they 3D print an electrochemical-machining rifling and chamber-boring mandrel.)

[@davidfarris1332]

A great trick for you! You can flip your single point threading tool upside-down and run your spindle backwards, which allows you to start a right handed thread from the inside at the undercut. This allows you to not have to worry about that nano second margin of error disengaging the thread pass without running into your stock or chuck.

[@Saanq]

Great video - nice to see the process of planning the nozzle build.

[@fredgenius]

Nice! I tried making my own nozzles in this way a few years ago, but it's a huge amount of work for something you can buy for very little. Now, I buy 0.3mm nozzles and drill them out to 0.35mm. The drill wobble you encountered @11:55 may be due to your headstock and/or tailstock alignment to the lathe's long axis. Barely noticeable on larger parts, but a killer for small carbide drills! As the nozzle hole is possibly THE most critical feature, maybe worth getting the alignment right...

[@TheBilgiOne]

What i did was, leaving more material in nozzle end for a better center to drill the 0,4mm and cut it away. For a better way of measuring the taper, index the cutter on a know surface (face of the leaved surface as written above), move to wanted cut area. After touching by looking at the dial you would know how much u plunged in... Do the math beforehand. And use the flats of the calipers when you have the chance rather then the sharp tips. Regard from a fellow aerospace student from aachen.

Nice lathe. As i want one for some time now too, you just made my decision which one to buy a littlebit easier...

[@andrewwilson8317]

You are correct,you could simply grind the drill tip to 60 degrees. Clamp a guide to your grinder and spin the drill against it in your fingers until the tip is all at this angle. Using the angle as a guide simply back the lands off a little on the grinder to give a nice rake clearance. Only a very little would be enough. Some drill sharpening jigs allow you to adjust the tip angle but it's really quite simple to do by hand and eye.

Changing a drill bit's tip angle to the required angle would work, though you may need to double check that the geometry is still good for cutting at the new angle and that it won't cause surface defects and has a good pilot hole
