Thank you for your appreciation and your comment. No, it's not my idea. It is a tool that I found in an old book for machinists and long forgotten.

That's what I wanted to do too. Thank you for your comment !

Welcome, my friend !

Your idea is good and it is not difficult to build. Someone said here that a cold air gun tool is also a healthy and useful choice. Thank you for your comment !

Thank you for your suggestion !

I am honored by your comment. The fact that you appreciate my work and give me a suggestion to improve my equpment, I will be proud to think that you are my friend. And yes, I will make a shield for the motor. Thank you !

It's really an improvement, just possibly unhealty. Thank you sir for your comment !

I discover every day that any idea can be improved, without exception. This is something that makes me happy. Thank you Mike for your encouragement and appreciation. It means a lot to me.

Yes, it was an idea, but I had to order a magnetic base and I needed it as soon is possible.Anyway, from the position where it is now, I will not move it. Maybe I won't use it because inhaling the vapors can be dangerous. I just found out from the comments. Thank you for your suggestion !

I am honestly in a big dilemma. It is a method widely used by experienced machinists. I was so happy that I finally solved one problem but it looks like I ran into another one. It's an issue I honestly hadn't considered until you comments. I didn't think about the risks of inhalig a dangerous substance. It was suggested to me in a comment that the solution might be an external air exhaust system from the spray area. I have something like that but not of great power. Thank you for sharing your experience with us and for your concern.

Yes, unless you are scrupulous about cleaning the machine after using mist will make a sticky mess. In the home shop even using flood coolant is not something I would recommend. In a job shop where the machine is used daily, keeping the coolant from turning into a smelly mess requires constant attention. In the home shop leaving coolant for a week in hot, humid conditions will leave the place smelling bad and a good way to get dermatitis on your hands. If you really need coolant, you might consider a cold air gun. Would be a good project to build on the lathe vs. buying one.

@@JIMMY916 I don't think it is a method widely used (anymore), and I just hope the hobby machinists stop using it asap.

The only drawback is the possible danger of inhaling the vapors. Otherwise, the method was good, especially for the milling machine where the chips were removed by pressure and the filming became explicit for the viewers. That's why many youtubers use this system. Thank you for your comment !

I am grateful for your comment. I don't know what solution I bought, but it is surprising to me that it is odorless. Next week I will read the label myself :) I had no idea about the cold air gun. Thanks for the suggestion and I will probably build one.

Thank you John ! Nice words as usual.

What makes me think is how dangerous it is to inhale these vapors. I didn't think about it until after I read a friend's comment. And yes Edward, UA-cam has rules that are sometimes more difficult to understand.

WOW. I really didn't think of that. Maybe someone who has been using something like this for a long time can answer us. This is indeed a good question. Thank you !

Technically not good but with the exception of factory’s with a large numbers of CNC machine centers with mist collection nobody I know worries about it unless you get some kind of allergic reaction .

There are several types of emulsion. Are they all identical or do they contain different components ? I don't think that the manufacturer's labels specify whether or not it is dangerous for health. This information should be mandatory.

​@@JIMMY916just in general i've found machining in a small space impacts air quality significantly. I have a bunch of air monitors from work that track particulates, various chemicals, vapours etc. Doing basic machining with cutting oils, lubricants etc set off a few alarms. That was without coolant running. Might just have been because i'm crap at machining. No idea if high particulates and chemicals in the air are much of a health issue but i prefer to have decent air flow through my workshop just to be safe. Set up a cheap extractor fan and air quality quickly improved.

Thank you for the information. My workshop is a little bigger than a matchbox and that is quite a problem for ventilation. I will look into this very carefully and use the solution you provided. But I seriously wonder if it's worth the risk. However, I have an amateur consolation.. I rarely work compared to those who have this job and work daily. Thank you for your time !

Yes. There are many methods. I think the liquid pan can be mounted above the level. Gravity would help a lot. Thank you for your comment !

@@JIMMY916No, it will siphon all of your liquid.

I was thinking about the help of gravity but with regulation of the flow through the tap. To no longer depend on air absorption. The only problem would be that I inadvertently forget to turn off the liquid valve when stopping work. It would be an unpleasant surprise next day.

I’m going though this process right now. The air pressure to Venturi the coolant out the tank is higher than I want. So I’ve pressurised the coolant tank using 3D printed parts and run a tap on the coolant line. Still in building phase but hopeful I can run much lower psi to achieve the same result. Plus have independent coolant and air taps.

Yes, it is a system that can be improved very easily. Thank you for your comment !

So did I, first job, works a treat.

Thats a good idea.

I needed something like this, especially since my hobby machines are a bit outdated. Thank you for your comment !

I think an improvement would be to move the liquid container above the level. Thank you for your comment !

@@clintchapman4319 Thank you very much !

I was referring to special tools for such things (like broach). Thank you for your comment !

@@dagorithe Thank you !

@@homemadetools Thank you!

@@IsZomg Thank you :))

@@philoso377 I think that would be a bit much for me, but thanks for the idea :))

@@JIMMY916”a bit much..” ?

I mean, one more boring moment will put everyone to sleep...

@@JIMMY916you may reply your update to this comment about the run out in the bull nose relative to the head spinal.

I didn't pay attention to a detail I noticed about my band. Not all teeth are the same size. They are 8 tpi but some are smaller in height than others (factory made). For cutting steel I am very satisfied with the cutting speed, only with aluminum it is difficult. This band was the most expensive on offer. I will try the alcohol method. I didn't know that was an option. Thanks for the info Michel !

@@JIMMY916 That's the vari-tooth design for quickly cutting thought steel, when the surface finish is not that important. Not ideal for aluminium, but it should cut.

I think there are several problems. Every comment I received suggest a fix. Inappropriate cutting band (even if it is 8 tpi), too low speed, pressure adjustment, lack of lubrication. Every advice can improve my situation and my conclusion is that, I will fix all these aspects following your advice. The cutting time depends on many possibly wrong settings that I neglected. I will fix the problems one by one and I hope to succeed. Thank you for the advice.

Yes, it has a cut pressure adjustment that I have never adjusted. When I get to the workshop I will increase the pressure. I think that was the problem. God bless you. God bless you all for your help.

Yes, I will be more careful. Bad habits are hard to correct. Three months ago I was working with gloves.. Thank you very much for your advice. People like you have corrected many of my mistakes.

@@JIMMY916However it is good to use gloves to remove chips, they will cut you badly.

@@pvtimberfaller Yes, when the chuck is not spinning. I learn my lesson :))

@@pvtimberfaller Needle nosed pliers is best, then you don't forget an take a shortcut and leave gloves on and lose a finger or your hand. Gloves have no place being near a machine of this type

@@joewhitney4097 Thank you very much for the appreciation ! It means a lot to me.

@@pvtimberfaller Yes, true. Unfortunately, I think I got used to it. Thank you !

So Just finished watching your video. At work we have a handheld belt sander (1” wide, about 2’ long) for polishing in the lathe. I have seen some for sale that you can clamp in a tool holder as well, that is what my dad used for finishing rifle barrels.

Can you please give more details ? Or a link where it is for sale ? Thank you !

It was on Alibaba, a machinery company in India. It would be pretty easy to build.

I assure you that the filet came out well. Its role is to support a magnet, nothing more And I know that being a long hole and made of aluminum, the tap is self-centering. If i were to redo this piece, I would do it exactly the same way. And so many say that I get involved even when it's not necessary Now it really wasn't necessary even if that's a "contradiction". :)) Thank you Chris for your comment !

@@JIMMY916 Jimmy, I didn't see or say anything about the pocket that seats the magnet. My comments were confined to Tapping only. Please reread what I posted. By the way, that comment you made about a tap self aligning in deep holes gave me chills! If you stick with that philosophy I would fully expect the dreaded.. "SNAP"!

@cdrive5757 Please be honest Chris. Do you think the tap broke or the thread came out crooked ?

@@JIMMY916 No, I don't think either, but someday it might be an extremely fragile 2-56 or 4-40 thread. I read through some of the comments left by others and something in particular grabbed my attention. There were viewers that complained about the length of this video. Comments like (I'm paraphrasing).."We don't need to see every single pass on the lathe". Your retort was "Those viewers that don't need to see it will just fast forward through that stuff". You then expressed the importance of keeping that footage for the less experienced. Jim, In keeping with that philosophy I stand by my disapproval of that tapping segment on the lathe. I think you know better and the "Shop Smart" methods that would have pleased your shop teacher. I know when I have to piss I tend to rush things! 😜 Motto to live by: Good shop practice takes practice! 🥰 Peace, young brother Jim

Hello, my big brother Chris :)) Six months ago, when I posted my first video, I was thinking about who would subscribe to my channel ? It never occurred to me that my audience would consist of professional machinist, teachers or engineers with almost 50 years of experience. This amazes me and honors me in the same time. I get free tips and lessons from the best. But unfortunately all this comes with a big downside. I can't impress you at all and that doesn't help me at all. I feel like if I were building a plane in my huge workshop, apart from ”nice work” we'd be talking about the paint it should be painted with. Nothing about project :)) Of course, I'm exaggerating now but you get what I mean. It would be unfair to say that I don't also receive extremely positive and encouraging comments, but I have friends who seem to intentionally avoid giving me feedback on the final product. Positive or negative, it doesn't matter. I think it's too early to ask that of you right now. My case is probably identical to that of a driver who has been driving for a year and already wants to participate in races. I have to remind myself that: it is an honor that you subscribe to my channel And yes, it is. It's just that sometimes I'm in a hurry. God bless you Chris

Unfortunately, we are not neighbors. But we are certainly brothers. Thank you very much for your nice words !

Thats is my first video...I would definitely do it differently now. Thank you for your comment !

If someone thought of a tool before me, it means that I was born late. In the end, I will have an idea that no one has had before me. I hope you won't get bored of me until than :)) As for chamfer the hole, I know that I do many things upside down. Something learned incorrectly can hardly be corrected. I assure you that I will do it in the correct order from now on. Thank you for another free lesson !

I am honored by your kind words. They are the encouragement I need to continue. And for that, my friend John, you made a happy man today.

I think my electric motor is too weak for aluminum cutting. My band is 8 tpi. That probably forces him. Or the speed is inappropriate. Thank you for your information !

Yes, it's 8 tpi. I think there is something wrong with the cutting speed. It's either too small or too high. I will use wd40. Maybe thats the problem. Or maybe the shape of the teeth is inappropiate for aluminum. Thank you very much for your comment !

What I don't understand is why you think that all the holes and threads are machine made I will give you only one example where you methods cannot be used. A screw on an engine block of a car that pulled the thread and it has to be redone to an increased size, my tool guarantees perfect alignment (your methods is useless). I am sure that our imagination does not stop at using this tool only on the lathe or milling machine where it is obvious useless. I am amazed at the confusion...It is an mobile tool, if you want.

@@JIMMY916 Yes, that's perfectly true. The method I saw used in some video is primarily useful immediately after drilling the hole when the workpiece is already clamped perfectly in place under the chuck.

You are right after all. I am the one who had to be perfectly explicit because I am the one who presented a new concept for the first time. If there is confusion, it means that I was not clear enough. I will be very careful about this aspect from now on. I promise. Thank you Edward for your comments !

Yes sir. ”NO MISTAKE ALLOWED” is probably the video you reffer.

Yes, a good alternative is to use a nut. Unfortunately, I don't have any nuts other than the extremely common ones. Thats why I thought of this centering device. But your idea is very good and I'm glad that you write to me and I learn new things. Thank you very much !

Correct ! Good and equally simple option. I will use it. Thank you !

For me it is very complicated to make this improvement... True, all profesional band saws have this option., but mine is a hobby toy. I will spray wd40 and I think I will better results. Thank you for your suggestion :)

I didn't think to use wd40 for cutting. I have used cutting oil on other occasions but without noticeable results. I will try your method. So the cutting band is not the problem ? I'm glad if that's the case. Thank you for your suggestion ! And for your time.

@@JIMMY916 The rule of thumb is the harder the material the more tpi you need. Aluminum is very soft so I recommend a courser tooth blade. I agree with the comment below about coolant but it isn't always practical with a hobby machinist so that's why I recommend a blade in the 14 to 18 tpi range and a lube stick, another trick I have done in the past is to place a blow down gun blowing sideways across the blade blowing the chips off the teeth as it comes out of the cut, again not practical but it helps a little bit.

Could it be the wrong speed for aluminum ? Is there a rule for cutting aluminum quickly ? For cutting steel I am very satisfied, only with aluminum it is difficult. My guess is that I am wrong here. Thank you for your time !

The videos on youtube that presented details in an explicit way as I present, taught me to work on the lathe. The presentation of details is for people like me. I am convinced that the experienced ones only look at the end. He is not interested in the production process at all. Thank you for your comment and for your appreciation !

@@JIMMY916Exactly!!! I love the detail and the lessons thereof. Even the sound of the turning is a reference guide to those of us finding our way to the light. Keep up the great work brother. I enjoyed every second of the class/video.

These are too big words for a beginner like me, but for that I thank you. God bless you for the encouragement, my brother !

@@DK-vx1zc Thank you very much for your appreciation !

Thank you very much !

You will have to teach me how to remove them from autocad. I do all my projects there but my IT knowledge are very limited. Could I take pictures of the sketches and send them to you email ? This is easy and I know how to do it :))

Unfortunately, as far as I know, it only exists in italian. If it's useful for you, let me know and I'll look for it.

@@JIMMY916 I'd love to have a copy of it. I'm sure that Google Translates can convert it to English for me if it's a digital copy. And I appreciate it very much.

I looked in my computer and can't find them. Instead, I found them on the internet. You have to look exactly as I tell you ”Maquinaria para Carpintero AT 520 MULTI- PURPOSE MACHINE” and you will find a PDF with all the information of my model. If you need other information, please ask.

@@JIMMY916 Found it! Many thanks. Your info leads me to another link with an English version of the same machine with different company on it. AT520 seems to be a popular model

@@JIMMY916 Any chance you can provide me with the 3 belt sizes for the lathe drive? There are 2 for low speeds and a single for the higher speeds. What I have is not correct.

I'm sure it's a total waste of time to tell you that the surface gets harder by pressing the metal. I'm not the only one saying this, experienced machinists like you have said it. But you can probably only achieve this with quality inserts.

Thank you my brother ! I am honored that you appreciate my work.

:)) Thank you for watching and for your time ! Your comment inspires me.

Thank you very much for your comment ! I'm not a fan of cold bluing but it is a frecvent used method too.

Yes, there are many things to improve. Thank you for your comment !
