hone a broader radius on your tool. or use a burnishing tool..they will get you a mirror finish since it is only that you are reproducing the standard of finish on the tip of your tool combined with straddling the peaks of the thread.
Hi Steve and thanks for your hint and comment. I’m sure that it will be useful for others to try out. However; these techniques do have limitations. For my own production of the Hypograph, it would not be suitable, because the wall thickness of the motor housing , would not support the pressure, causing deformation which is not desirable for that component part. This has a surface finish entirely generated by a single point HSS. cutting tool to obtain the required surface texture. You may find my website to be of interest. Cheers. 🍀K. www.ATKLINT.com

Thanks for your interesting comment. This reminds me of Sheffield in the 1950 era. There were many individual businesses there and known as the “ Little Mesters”. They worked as finishers in the cutlery industry, polishing preformed blanks of knives, forks and spoons etc. I don’t know about the green waxed bar you mention, but I have used a brown one to polish a cast aluminium product. This was used on a buffing wheel with perhaps a 6” diameter polishing pad made up of layers of cloth. This did produce a high shiny finish. The downside to this, was the definition to angular sides and corners of the article was compromised. It was probably due to the high peripheral speed of the machine; the spindle speed was around 3000 RPM. It may be worth a try, but my opinion is that it would be doubtful if a better finish could be obtained on a lathe with a maximum speed of around 2000 RPM. with a workpiece of only 1” nominal diameter. Also the desired contrast to angular sections may be degraded, which is not desirable for the component parts of the design shown on the video. However; you could give it a try. Note also that carbon or stainless steel alloys, as used in knife manufacture, are much harder than the aluminium example shown on the video. 👍🍀
in a working machinist environment its sometimes the case that a polished finish is unacceptable anyway and that it must be a machined finish .got to stick to the prvided spec unless told otherwise.always better if you can aviod having your fingers anywhere near rotating parts .Emery paper and other abrasive papers can bite unexpectedly and pull your fingers in .
Quite right Steve and risk assessment should always be considered, in order to avoid undesirable incidents. In this video, the part being machined, is a component for a spaceship and the finishing process is to demonstrate what can be achieved in a typical home workshop with limited tools and experience. In this instance, it is my own design and specifications for production of a spaceship to be used by kids. I made it for a Christmas present and there’s much more to it than that shown on the video. Incorporated are sliding and push fits with partial vacuum operation for the command module. These are demonstrated on a later video that I published following successful launch and recovery trials. You might like to check them out. 🍀K
Certainly seems to work, though I can see that getting a consistent finish across the piece takes time and practice. For the tool, is a knife shape or round nose better, and would you use lubricant ever for the finishing cut? Thanks 😀 👍
OK, yes to get good results does take time and practice. It really is just a matter of experience. Regarding choice of tools, would be dependant on the material to be cut, also whether or not you need to have a radius of the corners of the shoulders. In that case I would use a round nose tool, because it would be easier to generate the radius, often specified to ensure a greater tensile strength to a component part. On the question if ever I would use lubricant or coolant during a finishing cut; generally I find it non-essential. However ; this could also depend on the material being machined. For example brass, copper and cast iron, definitely not. The latter contains an element of graphite, which is to some extent self lubricating. If machining special steels including 18 % HSS tool steel and harder materials, it could be advantageous to use coolant to disipate heat and prolongue tool life. As previously mentioned, it's all a matter of experience! A good idea, would be to experiment with the various options, which would also develop your skills and knowledge. Thank you for your questions and I hope my response will be useful for you and others interested in this aspect of machining. 🍀 K
Hi Brian and thank you for your comment. This is the first time I have been notified that a large ball bearing can be used for a finishing cut. It would be interesting to know more about this technique, so could you explain with further details? In engineering, there is always something new to learn, even for well qualified people like myself. I feel sure that many others would be also interested in this, so I look forward to learning more about it in any further comments. 🍀 K
I've only seen it on TH-cam, but I think the technique is called burnishing, where a hard ball plastically deformes any ridges into a smooth surface. For some alloys, this also provides a work hardened surface. I've seen watch maker lathe operators using ruby for burnishing also.
Thank you for the explanation and burnishing is a technique that I have heard about, however; it is quite different from a finishing cut from the tool post cutting tool. There are also limitations; it just would not be practical or even not possible to attempt this process, where work piece bores and wall thickness are minimal with critical tolerances. Thank you for your follow up on this issue, it is most appreciated.🍀K
Great tips Keith .I have seen people on other videos using an attachment with a ball bearing to smooth out imperfections which seem to give a good finish as well. Thanks for sharing
Thanks for your comment Vince. Yes but it has limitations and I never use this method, as all my surface textures are achieved with a single point HSS cutting tool. 🍀K
Hi Paul, thank you for asking the questions about this project. Well now, it’s not so easy to answer about material costs, because I already had the aluminium bar in stock, which normally is bought in lengths of 3 metres. You should find a supplier without much difficulty and they usually can supply in shorter lengths of perhaps only 1 metre. That may be adequate for you initially and not too expensive, but I don’t know the current costs. Regarding how much do they sell for; well I have not considered this at all. The reason why I made this was because I wanted a special present to give to a very special grand daughter. There was no intention to go into production, so a selling price was not a consideration. If you want to produce for sale, then you would have to determine your own price for this, considering design and production costs. You may find some of my earlier videos useful, about the Master Class in Marketing for example. Please check them out and I hope my response to your questions is helpful for you. 🍀 K

Hi I'm guessing I'm about the same age as you and it's a challenge to keep up with all the new tech. Good to go back to basics you can't polish a turd! Concentrate on the best tool finish and not trying to make a bad finish better. Very hard at times to hear what you say withe the lathe growling at 1000rpm six inches from the mic and you about four feet away. Try changing the grind on your last cut and get a better chip break on the tool. That will stop the birds nest building up at the cutting edge and scratching your workpiece
Hi and thank you for your comments. I realise it can be difficult at times to hear what is being said, over the sound of machinery. The speed in this was about maximum, 1,400 R.P.M.

Hello Jonathan and thank you for raising the issues of safety when using a lathe without guards. It is good to be safety conscious when in a workshop environment, however; please be aware that: * My videos are not made for kids. * Lathes are not made for kids. * Lathes are not toys for kids to play with. * Not all lathes are fitted with guards. * Many persons having accidents with lathes, may not have had basic training from a qualified instructor. * Before initiating any machining operation, be sure to understand the need for RISK ASSESSMENT!

@@Roadrash-fk9rn Thank you for your comment, however; it is considered good and safe working practice in industrial machine shop engineering to wear appropriate protective clothing.

I can say quite definitely, that from my previous practical experiences and studies of this subject in many machine shops and being also responsible for education in training establishments, that I can confidently state the following conclusion. I certainly do know better than to wear short sleeved garments, when in a machine shop environment. If you ever have the misfortune to suffer the experience of having a hot curly blue steel chip clinging to any exposed part of your anatomy; then you will know why! 🍀 www.ATKLINT.com
All you have done there is polished the peaks and troughs if you wanted a mirror finish you have to bottom the surface out by going through the grits ending up on diamond pasts and then buffing the surface so it’s perfectly flat.
Thank you for your comment Bryn. You’re quite right of course and I have previously produced mirror finishes on certain components specified by the admiralty for one of their destroyers. A diamond lap was used for that job. Unfortunately that vessel was sunk by an Exocet missile during the Falkland dispute. However; the video is to show how to achieve a super smooth finish, using a single point H.S.S. Cutting tool. It is possible to generate a similar finish, by using a different type of tool with a much higher spindle speed, that is not usually available in the average home workshops. 🍀 K. www.ATKLINT.com
Thanks Keith. suggestions: use smaller cloths without fibers hanging and dont wrap them around to avoid getting them sucked in and taking your hand off. your focus is a bit off, its on the slide not the work. its good to give multiple angles and see you talking once in a while. also if your showing so much hand action, trim those fingernails! :) Thanks for the vid, nice result!
Haha, thanks I do like your comments and I have submitted to a manicure a couple of days ago. 🤗 The hand movement is important to be continuous, hence the reason for the focus on that. It's not really easy to get the ideal view of everything, because the camera in some situations restricts operational movements. I hope that others will notice your valid and useful comments. Thanks for your response. 🍀
Hello the speed seem frightening and its my opinion I don't think is agood idea to use a cloth rag ona lathe As it could get caught up and cause an accident having said this I am not an engineer by trade I do have an old Boxford lathe as I am I the process in making a model steel engine. Doing that job I would use a paper towel to apply the polish that would would not be strong enough to pull the hand onto the lathe, impressed with finish Did you have a Velocite .
Hi Richard, thank you for your comments which are most appreciated. You are quite right to say that the material could be caught up and cause an accident. That is why extreme caution should always have to be considered, especially when working close to the chuck at high speeds. In this video the spindle speed was about 1,800 R.P.M. Even at slow speeds, I have known loose clothing to be entangled by the lead screw, where the operator was pulled into a lathe causing an avoidable accident. It is essential to ensure the material being used, is held in a position where if caught by the workpiece, it would not endanger hands or fingers; therefore it must never be wrapped around them. Always be aware of eventualities before processes begin; it’s (risk assessment). I would not use paper towel for this process, because it could be quite messy as it degrades and not have the resilience to achieve the desired outcome. Your Boxford lathe should be great for your steam engine project and I wish you success and good luck as progress continues. There may be frustrating moments at times when the theory and practice of machine shop engineering can be fraught with difficulties. Keep at it and you’ll succeed. Please update us on your progress, as it will be helpful for others viewing this channel. Thanks and good luck. 🍀K You may find my website of interest! www.ATKLINT.com

Your contribution and interest is most appreciated. 🍀 K www.ATKLINT.com
@@muchlote Thank you for your comment. I find that it is not always possible to place the camera in the optimum position, due to the subject matter being addressed and the proximity of moving machinery.

I used a Motor with a Cloth Buff mounted in the Tool Post and some Buffing Soap >> You cannot beat it > Try it, but make sure your Medical insurance is up to date because you might have a Heart attack from the blinding results !
Yes thank you for your comment Graham and I do know that method can produce good results. There are however issues that could arise when using buffing wheels and great care must be taken during their use. They can be very aggressive and may remove or degrade surfaces of the workpiece. The result being distortion of edges and corners, or angles of edges or shoulders, which in most case’s would not be a desirable feature. It is also sometimes difficult to remove all of the residues of Buffing Soap, although certain colours maybe easier than other grades, which could be less abrasive during application. I’m sure your method will be useful for others to know about, but with reference to the above mentioned caveat. Cheers, K. 🍀
Its all about sfm, spindle speed and cut depth. In other words, experience. There is no 'one size fits all' method to achieving a polished finish. Make chips that dont need dips!
You’re quite right of course and thanks for your comment. There are various ways to achieve a desired surface finish. Practical experience will ultimately determine the parameters and techniques needed to produce the surface texture required for the work piece. This could also be variable, depending on the material to be machined. 🍀
Not as applied to lathe work; but have observed the excellent finish for the production of cold rolled strip. The metal is compressed at very high pressure, between large diameter steel rollers, which also have a similar mirror type of finish. This causes the material to stretch and therefore reduces thickness to a high degree of accuracy. A typical application for producing stainless steel strip as razor blades and much larger dimensions for stainless steel sheets. Thank you for your interesting comment and please feel free to expand further. I assume a special type of roller would be necessary to fit on a tool post.
@@keithatklint5380 I saw a video from a commercial supplier and was impressed, so being a cheapskate I made my own. Nothing more than a hardened oval sectioned steel ring on a ball bearing in a holder similar to a single wheel knurl. The oval section concentrates the pressure to a small area to reduce loads and is therefore kinder to the lathe than a single wheel knurl. Just by coincidence I have a video showing mine in use.😉 They work by compressing the ridges but, depending on the turned surface, do not reduce the diameter by more than a few microns Not only is the finish improved but surface is "toughened" to. Its not a process for all occasions but its a handy technique to have available for the times when it is. As I say in the video, it is not a common thing for the homeshop environment but I think it should be better known. Commercially there are internal ones to, but they are of very limited size adjustment and if I say "not cheap" that is not an exaggeration. 😉 Have a look at the video and see what you think. No charge!😃

My reply regarding lost body parts, wouldn’t be as you predict, but would mention that; I know of tragic accidents where this has occurred, having catastrophic life changing results.
Obviously, no one would want any kid or adult to suffer personal injury; but if such an incident were to happen as mentioned in your post; then be sure that any litigation instigated by yourself, is directed only against the person responsible for this in the first instance.
Oh shut up, no one asked you to be the mother of the internet.
@@keithatklint5380Hi Keith, I wonder what Jonathan Rose is going to do if his kids watch videos of workers in Pakistan. You’re better off just blocking him. He’s an American of course.
@scroungasworkshop4663 Hmm yes I know what you mean here. It does make you think doesn’t it? Whenever my technical ability is questioned, I always try to justify my methodology, in order to make it absolutely clear that I will not tolerate unjustified criticism from less qualified sources. My responses are also for the benefit of the many thousands of other viewers like yourself, who would post more constructive comments and I do appreciate your support in this respect. For this reason, I have not as yet blocked any person’s negative remarks. 🍀K.

Long sleeve shirt with a high speed chuck = loss of limbs 👎
@@Roadrash-fk9rn Thank you for your comment, however; it is considered good and safe working practice in industrial machine shop engineering to wear appropriate protective clothing. This includes overalls, smocks or tops with long close fitting sleeves.
It is considered hazardous for a machinist to wear short sleeved shirts, which would certainly not be in compliance with acceptable safe working practices.
I intend to be addressing the issue of RISK ASSESSMENT in a future video, which you may find helpful. 🍀K.

You should know better, not to wear long sleeves.
Thank you for your comment and I have responded to this subject several times now. You may find it useful to check the other views about this.
I can say quite definitely, that from my previous practical experiences and studies of this subject in many machine shops and being also responsible for education in training establishments, that I can confidently state the following conclusion.
I certainly do know better than to wear short sleeved garments, when in a machine shop environment.
If you ever have the misfortune to suffer the experience of having a hot curly blue steel chip clinging to any exposed part of your anatomy; then you will know why! 🍀

All you have done there is polished the peaks and troughs if you wanted a mirror finish you have to bottom the surface out by going through the grits ending up on diamond pasts and then buffing the surface so it’s perfectly flat.
Thank you for your comment Bryn. You’re quite right of course and I have previously produced mirror finishes on certain components specified by the admiralty for one of their destroyers. A diamond lap was used for that job.
Unfortunately that vessel was sunk by an Exocet missile during the Falkland dispute.
However; the video is to show how to achieve a super smooth finish, using a single point H.S.S. Cutting tool.
It is possible to generate a similar finish, by using a different type of tool with a much higher spindle speed, that is not usually available in the average home workshops. 🍀 K.

Thanks Keith. suggestions: use smaller cloths without fibers hanging and dont wrap them around to avoid getting them sucked in and taking your hand off. your focus is a bit off, its on the slide not the work. its good to give multiple angles and see you talking once in a while. also if your showing so much hand action, trim those fingernails! :) Thanks for the vid, nice result!
Haha, thanks I do like your comments and I have submitted to a manicure a couple of days ago. 🤗 The hand movement is important to be continuous, hence the reason for the focus on that. It's not really easy to get the ideal view of everything, because the camera in some situations restricts operational movements.
I hope that others will notice your valid and useful comments.
Thanks for your response.

Hello the speed seem frightening and its my opinion I don't think is agood idea to use a cloth rag ona lathe
As it could get caught up and cause an accident having said this I am not an engineer by trade I do have an old Boxford lathe as I am I the process in making a model steel engine. Doing that job I would use a paper towel to apply the polish that would would not be strong enough to pull the hand onto the lathe, impressed with finish
Did you have a Velocite .
Hi Richard, thank you for your comments which are most appreciated. You are quite right to say that the material could be caught up and cause an accident. That is why extreme caution should always have to be considered, especially when working close to the chuck at high speeds. In this video the spindle speed was about 1,800 R.P.M. Even at slow speeds, I have known loose clothing to be entangled by the lead screw, where the operator was pulled into a lathe causing an avoidable accident.
It is essential to ensure the material being used, is held in a position where if caught by the workpiece, it would not endanger hands or fingers; therefore it must never be wrapped around them. Always be aware of eventualities before processes begin; it’s (risk assessment).
I would not use paper towel for this process, because it could be quite messy as it degrades and not have the resilience to achieve the desired outcome.
Your Boxford lathe should be great for your steam engine project and I wish you success and good luck as progress
continues. There may be frustrating moments at times when the theory and practice of machine shop engineering can be fraught with difficulties.
Keep at it and you’ll succeed. Please update us on your progress, as it will be helpful for others viewing this channel.
Thanks and good luck. 🍀K

I recommend using sandpaper once before using the polishing cloth to avoid getting the surface too rough and causing it to get caught.
Thank you for your comment.
It really is a case of being what is right for your application and what suits your personal preference, in order to achieve the desirable outcome.
I am not able to comment on applying sand paper, as this is something I have never used, as it could present issues in respect of proximity to centre lathes, or other engineering machinery.
Your contribution and interest is most appreciated. 🍀 K

Tha camera is too close to the Cone.
@@muchlote Thank you for your comment. I find that it is not always possible to place the camera in the optimum position, due to the subject matter being addressed and the proximity of moving machinery. Another consideration is, if the camera is placed too far away from the object, the sound quality could suffer.
I don’t intend to compete with professional film production companies like MGM, but I just try to do the best I can with the available resources. Please also be aware that, all my videos have not been edited, so what is published is what you get, even though sometimes things may go wrong; that’s just the way it is. Your observations and any suggestions are always welcome. 🍀K

@@keithatklint5380 I do unserstand the issue, the only reason I comented was the blurr it couses on the viewers.
The worst you'll get is a bruised knuckle
@EitriBrokkr Hmm I do know what you mean and special care is required. 🤔Thanks for your comment. 🍀K
I used a Motor with a Cloth Buff mounted in the Tool Post and some Buffing Soap >> You cannot beat it > Try it, but make sure your Medical insurance is up to date because you might have a Heart attack from the blinding results !
Yes thank you for your comment Graham and I do know that method can produce good results. There are however issues that could arise when using buffing wheels and great care must be taken during their use.
They can be very aggressive and may remove or degrade surfaces of the workpiece. The result being distortion of edges and corners, or angles of edges or shoulders, which in most case’s would not be a desirable feature.
It is also sometimes difficult to remove all of the residues of Buffing Soap, although certain colours maybe easier than other grades, which could be less abrasive during application.
I’m sure your method will be useful for others to know about, but with reference to the above mentioned caveat.
Cheers, K. 🍀
Its all about sfm, spindle speed and cut depth. In other words, experience. There is no 'one size fits all' method to achieving a polished finish.
Make chips that dont need dips!
You’re quite right of course and thanks for your comment. There are various ways to achieve a desired surface finish.
Practical experience will ultimately determine the parameters and techniques needed to produce the surface texture required for the work piece. This could also be variable, depending on the material to be machined. 🍀
If you would like to get that finish on just about any metal without even using Solvol have you come across roller burnishing?
Not as applied to lathe work; but have observed the excellent finish for the production of cold rolled strip. The metal is compressed at very high pressure, between large diameter steel rollers, which also have a similar mirror type of finish. This causes the material to stretch and therefore reduces thickness to a high degree of accuracy. A typical application for producing stainless steel strip as razor blades and much larger dimensions for stainless steel sheets.
Thank you for your interesting comment and please feel free to expand further. I assume a special type of roller would be necessary to fit on a tool post.
@@keithatklint5380 I saw a video from a commercial supplier and was impressed, so being a cheapskate I made my own. Nothing more than a hardened oval sectioned steel ring on a ball bearing in a holder similar to a single wheel knurl. The oval section concentrates the pressure to a small area to reduce loads and is therefore kinder to the lathe than a single wheel knurl. Just by coincidence I have a video showing mine in use.😉
They work by compressing the ridges but, depending on the turned surface, do not reduce the diameter by more than a few microns Not only is the finish improved but surface is "toughened" to. Its not a process for all occasions but its a handy technique to have available for the times when it is. As I say in the video, it is not a common thing for the homeshop environment but I think it should be better known. Commercially there are internal ones to, but they are of very limited size adjustment and if I say "not cheap" that is not an exaggeration. 😉
Have a look at the video and see what you think. No charge!😃
Thanks for that and I have just checked out your channel, left a comment and also subscribed. 🍀
